Description

Detailed Description of the Invention

[0001]

The present invention relates to an improvement in an ultraviolet sterilizer.

[0002]

2. Description of the Related Art Conventionally, an ultraviolet sterilizer is used for sterilizing the inner and outer surfaces of food containers, cups and the like. As a conventional ultraviolet sterilizer, for example, as shown in FIG. 4, a reflector 2 and a light source 3 are mounted inside an irradiation apparatus main body 1, and a light shielding plate 4 is arranged in a front part of the light source so as to be capable of protruding. Is configured.
According to the ultraviolet sterilizer, it is not necessary to turn off the light source by arranging the light shielding plate 4 in front of the light source at the time of no sterilization. Therefore, at the time of sterilization, sterilize food containers, cups, etc. with stable ultraviolet rays. You can

[0003]

However, when the light shielding plate is projected and inserted, since the light shielding plate protrudes beyond the end of the ultraviolet sterilizer, it is necessary to make a large installation space for the ultraviolet sterilizer. There is also a drawback that the ultraviolet device itself becomes large.

The present invention has been made in view of the above points, and provides an ultraviolet sterilizer which can be constructed in a small size and which does not require a large installation space for the ultraviolet sterilizer. With the goal.

Means for Solving the Problems The present invention has the following structure to solve the above-mentioned problems. That is, according to the first aspect of the invention, a plurality of elongated light sources are mounted inside the elongated ultraviolet irradiation apparatus main body, and a semi-circular light-shielding / reflecting body is rotatable around each light source. It is arranged and configured. In addition, each reflector is connected by an interlocking gear, each interlocking gear is integrally rotated by a drive gear, and each reflector is configured to cover a part of the cylindrical light source in cross section when ultraviolet rays are reflected and when ultraviolet rays are blocked. There is.

According to a second aspect of the present invention, a plurality of elongated light sources are horizontally mounted in a straight line inside the elongated ultraviolet irradiation apparatus main body. Further, a semi-circular light-shielding / reflecting body is rotatably arranged around each light source. Further, each reflector is connected by an interlocking gear, and each interlocking gear is configured to rotate integrally with a drive gear.

BEST MODE FOR CARRYING OUT THE INVENTION The ultraviolet sterilizer of the present invention will be described below with reference to FIGS. 1 to 3, reference numeral 11 denotes a horizontally elongated sterilizer main body having an opened lower surface, which is made of, for example, a stainless material. The sterilizer main body 11 has a length of 1200 mm and a horizontal dimension of 180 m, for example.
m, the vertical dimension is about 80 mm.

Reference numeral 12 denotes a light source mounted inside the main body 11 of the ultraviolet sterilizer, for example, a 65 watt ultraviolet sterilization light source 12 is mounted. Further, the ultraviolet sterilization light source is configured by mounting three lights in a straight line in the horizontal direction. In addition, the same light source is 1 to 5 depending on the amount of UV irradiation.
Configure to light.

Reference numeral 13 denotes a light-shielding / reflecting member which is rotatably arranged around each light source and has a paraboloidal cross section. The light-shielding / reflecting body is made of, for example, an aluminum alloy. Further, the light-shielding / reflecting body is configured to cover about half of the cylindrical light source having a cross section at the time of ultraviolet ray reflection and at the time of ultraviolet ray shield. Further, the distance from the lower end of the light source mounted inside the ultraviolet irradiation device to the work is, for example, 20 mm.
Configure to a degree.

Reference numeral 14 is a main gear arranged near both ends of each light-shielding / reflecting body 13, 15 is an interlocking gear linked to the main gear 14, 16 is a drive gear, and drives the drive gear 16. As a result, the main gear 14 and the interlocking gear 15 rotate, and the light-shielding / reflecting body 13 is inverted. Reference numeral 17 is an air actuator for driving the drive gear 16.

According to the ultraviolet irradiation device having the above structure,
All the light-shielding / reflecting bodies can be opened and closed at the same time, so that the entire work can be irradiated with ultraviolet rays on average, and the light can be shielded at the same time.

[0012]

As described above, according to the present invention, the light-shielding / reflecting body is arranged in each light source, and all the light-shielding / reflecting bodies are opened and closed at the same time. Therefore, the conventional ultraviolet irradiation device can be constructed in a small size. Moreover, it has a special effect that does not require a large installation space for the ultraviolet sterilizer.
