Two sockets (9) for 5) are fixed and a germicidal lamp (5) is fitted therein, and a blower (6) with a motor is further fixed in series with the germicidal lamp (5).

Description

[Detailed description of the device]

[Industrial applications]

 The present invention relates to an indoor air sterilizer for removing airborne bacteria in indoor air.

[0002]

[Prior art]

 Conventionally, sterilization of indoor air, which is performed in hospital rooms and the like, has been performed by using a chemical or by attaching a cover to a sterilization lamp and fixing it to the ceiling.

[0003]

[Problems to be solved by the device]

 In recent years, nosocomial infections in hospitals have been increasing, and in particular, many infections have been caused by methicillin-resistant Staphylococcus aureus and many deaths have occurred. The cause is that resistant Staphylococcus aureus was created by variously using antibiotics in patients infected with Staphylococcus aureus due to various reasons on the hospital side. Methods to prevent this infection mainly include hand washing of medical staff and inpatients and removal of airborne bacteria in the air in the patient room. Dispersion of drugs used as one of the two methods requires considerable caution due to their adverse effects on the human body, and the duration of efficacy is also temporary, so they are not implemented as much as they are time-consuming. It has become impossible to be done. Another method is to install a germicidal lamp on the ceiling of the patient room, but this method uses the natural circulation of room air, so the sterilizing speed cannot keep up with the inflow and outflow of air as people enter and leave the patient room. Has stopped only air sterilization around the germicidal lamp. According to this method, ultraviolet rays have a short wavelength and collide with anything in the air and diffusely reflect, so that they leak out of the cover. Therefore, they are naturally radiated and harmed to the human eyes. The problem to be solved by the present invention is that it does not produce resistant Staphylococcus aureus as in the case of using a drug, and puts a germicidal lamp in a case so that ultraviolet rays do not completely leak to the outside. , The ultraviolet light emitted from the germicidal lamp completely destroys the DNA (deoxyriboacid) and RNA (ribonucleic acid) in the cells of floating bacteria in the air in the hospital room, so forced circulation of the air in the patient room The object of the present invention is to provide an indoor air sterilizer that speeds up the sterilization rate and keeps the interior of the patient room in a sterile condition at all times.

[0004]

[Means for Solving the Problems]

 The indoor air sterilizer according to the present invention solves the above problems and is as follows. The indoor air sterilizer according to the present invention is provided with an inlet (2) near one end of a box-shaped case body (1) and an outlet (3) near the other end of the box body (1). An air passage (4) is provided between the intake port (2) and the discharge port (3), and a germicidal lamp (5) and a blower (6) are radiated to the air to emit ultraviolet rays in the air passage (4). In order to irradiate as long as possible, they are fixedly arranged in series with appropriate intervals. In addition, the germicidal lamp (5) and the blower (6) are wired from a power cord (7) having an outlet (8), and the power source may be DC or AC. Use the one suitable for the power supply, and use the well-known circuit according to the power supply used for the germicidal lamp (5). The indoor air sterilizer according to the present invention is designed to be used by mounting it on a table. However, without being particular about this, screw holes may be provided on the bottom surface and screwed to the wall, or the adhesive may be used. Or double-sided tape may be used. Further, the disinfection lamp (5) and the blower (6) may be mounted in either the front or rear order.

[0005]

[Action]

 To use it, either in the hospital room or in a necessary place, either seriously put it on the table or fix it to the wall with bis, adhesive and double-sided tape, but if you connect the outlet (8) to the power supply The sterilization lamp (5) lights up and the blower (6) rotates. The operation at this time is that the air in the patient room or the like is sucked into the case body (1) from the air inlet (2) by the blower (6) and is irradiated with the ultraviolet rays emitted from the germicidal lamp (5). It is sterilized by this and is discharged from the discharge port (3), and thereafter this action is repeated. Therefore, the air in the patient room is sterilized by circulating in the patient room.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the drawings. A box-shaped case body (1) is provided with a suction port (2) near one end and a discharge port (3) near the other end. Two sockets (9) for the germicidal lamp (5) are fixed to the bottom of the body (1), the germicidal lamp (5) is fitted, and a fan with motor (6) is connected in series with the germicidal lamp (5). Then, the germicidal lamp (5) and the blower (6) are wired from the power cord (7) having the outlet (8).

[0007]

[Effect of device]

 The main cause of nosocomial infection is due to methicillin-resistant Staphylococcus aureus, and deaths are common. This methicillin-resistant Staphylococcus aureus was artificially created by heavily using antibiotics in patients infected with S. aureus. Therefore, even in the future, even if a drug that can cope with the current resistant S. aureus is created, resistant S. aureus in that drug will continue to occur. Therefore, as a means to remove resistant Staphylococcus aureus, it must be treated from the environment in the hospital. Therefore, the best treatment method that does not rely on chemicals is the method that uses ultraviolet rays, which destroys the cells of resistant Staphylococcus aureus and kills them, but it is a well-known technique. In this natural circulation method, air sterilization is concentrated around the sterilization lamp and does not reach the entire room, and the sterilization speed cannot keep up with the inflow and outflow of air as people enter and leave the hospital room, but the wavelength of ultraviolet rays is shorter. It leaks out of the cover where it collides with anything in the air and is diffusely reflected, thus irradiating and harming the human eye. According to the indoor sterilizer of the present invention, a germicidal lamp is housed in the case to prevent the ultraviolet rays from completely leaking to the outside, and the air in the hospital room is sterilized and forcedly circulated to accelerate the sterilization speed. It is possible to keep the interior of the hospital room sterile.
