Description

[Detailed description of the invention] This invention is designed to prevent bacteria on the walls, ceilings, floors, and surfaces of instruments placed in rooms such as operating rooms and hospital rooms, as well as bacteria floating in the air of the rooms. This relates to a sterilizer that kills bacteria, etc.

Conventionally, this type of sterilization device has multiple ultraviolet germicidal lamps attached to the main body of the device at variable angles, and by manually changing the angle of these germicidal lamps, the range of ultraviolet rays irradiated by these lamps is adjusted. was there.

However, in such conventional devices, (a) the amount of ultraviolet rays emitted from the device varies depending on the direction, and there are directions in which the ultraviolet rays cannot reach a sufficient distance; The irradiation range is narrow, leaving a large area that cannot be sterilized.

(b) Manually adjust the angle of the germicidal lamp one by one.
The distribution of the amount of ultraviolet rays, the size of the room, the distance between devices,
It is necessary to create a condition that best suits the installation location of the device.

(c) Since the ultraviolet rays emitted from each germicidal lamp are emitted in multiple directions, the amount of ultraviolet rays irradiated per unit area is small, and a sufficient sterilizing effect cannot be obtained even within the range where the ultraviolet rays are irradiated.

(d) If we try to increase the amount of UV irradiation per unit area by installing a reflector around each germicidal lamp to focus the UV rays, the actual range of UV irradiation will become even narrower. You can't do that.

(e) In order to make the irradiation range of ultraviolet rays as wide as possible, it is necessary to install a large number of germicidal lamps.

(F) As mentioned in the previous section, a large number of sterilizing lamps are required, and each of these sterilizing lamps can be attached to the main body of the device at variable angles, so the space occupied by the device during use becomes very large.

There were drawbacks such as.

Then, the contact 27 fitted into the groove 28 formed in the cam 23 moves into the guide hole 61 as shown by arrow E in FIG.
reciprocate horizontally along the

Therefore, the swinging arm 25 swings back and forth within a predetermined angular range as shown by arrow A in FIG.

At this time, the contact support member 62 reciprocates in the length direction of the swing arm 25 when viewed from the swing arm 25.

According to the swinging movement of the swinging arm 25, the sphere 30 rotates in all directions relative to the swinging arm 25, and also moves linearly in the longitudinal direction of the arm 25. conduct.

On the other hand, the rod 35 moves horizontally relative to the sphere 30.

As a result, the rod support 34 performs reciprocating rotational movement within a predetermined angular range as shown by arrow C in FIG.

The reciprocating rotational motion of the rod support 34 is transmitted to the oscillating body 40 via the shaft 33, the cap gears 37, 39, and the oscillating body support shaft 38a, so that the oscillating body 40 also moves to the oscillating body support shaft 38a. a, 38b as the centers, reciprocating rocking motion within a predetermined angular range as shown by the arrows in FIG. (It is defined as a 180 degree range from horizontal to horizontal).

As a result of the above, the sterilizing lamp 41 is rotated around the rotating body support shaft 4 and at the same time is oscillated around the rocking body support shafts 38a and 38b, so that the ultraviolet rays irradiated from the lamp 41 Since all directions are scanned during a certain period of time, there will be no direction that is not irradiated with ultraviolet rays.

Also, of course, there is no need to manually adjust the angle of the germicidal lamp 41 depending on the size of the room, the installation location of the device, etc.

In addition, in this device, since the ultraviolet rays emitted from the sterilizing lamp 41 are focused by the reflecting mirror 42, the amount of ultraviolet rays irradiated per unit area can be greatly increased, so the sterilizing effect is dramatically improved compared to the conventional one. can be increased to

In addition, since ultraviolet rays are scanned and irradiated in all directions by rotating and swinging the germicidal lamps 41 as described above, the number of germicidal lamps 41 can be reduced.

Furthermore, since it is sufficient to rotate and swing a small number of germicidal lamps 41 in this way, the space occupied by the device can be reduced.

In addition, in the present invention, the shape of the reflecting mirror is not limited to the shape as in the above embodiment, and it goes without saying that a reflecting mirror having a parabolic cross section, for example, may be used.

Further, the drive device for driving the rotating body and the oscillating body is not limited to the mechanism as in the above embodiment, and other mechanisms may be used.

In the above embodiment, the device that drives the rotary body and the drive device that drives the oscillating body share a part of the same mechanism, but the device that drives the rotary body and the drive device that drives the oscillator have a common mechanism. They may be made independent of each other.

However, if the mechanism is as in the embodiment described above, the thickness of the rotating body can be reduced, and the rotating body can prevent a blind spot for ultraviolet ray irradiation from occurring below the device.

Further, in the above embodiment, the device is installed on the floor, but the sterilizing device according to the present invention may be installed on the ceiling or the like.

As described above, the sterilizer according to the present invention includes a rotating body that is rotatable about a shaft extending in the vertical direction, a rocking body that is rotatable around a shaft that extends in the horizontal direction, and a rocking body that is attached to the rocking body to perform ultraviolet sterilization.
