Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable sterilizer having a built-in ultraviolet lamp which emits ultraviolet rays having a sterilizing action or generates ozone gas having a sterilizing action.
In particular, the present invention relates to a sterilizing apparatus capable of suitably performing sterilization at a location that is difficult to access with a conventional sterilizing apparatus such as a high place that is not accessible, a narrow gap or a corner portion of equipment, or the like.

[0002]

2. Description of the Related Art In recent years, unprecedented types of food poisoning occur frequently, and the hygiene of food and cooking environments has become a problem. In addition to hand washing and disinfection at home and outdoors, tableware,
As a measure against the sterilization of cooking equipment and food materials, a portable hand-held sterilizer with a built-in ultraviolet lamp has been proposed so as to be easily used at home or outdoors.

This portable hand-held sterilizer has an ultraviolet lamp provided on one side of a compact apparatus main body, and can sterilize an object such as tableware and food by exposing the object to ultraviolet light from the ultraviolet lamp. is there. And
Because it is a portable and compact sterilizer with a built-in power supply and control circuit such as a battery, it can sterilize everything by holding the sterilizer and irradiating it with an ultraviolet lamp. ,
It can be used not only at home but also outdoors.

[0004]

However, the above-mentioned conventional sterilizing apparatus continuously sterilizes a wide surface by slowly moving an ultraviolet lamp close to an object such as tableware or foodstuff placed close by. However, it was difficult to sufficiently irradiate ultraviolet light in high places where it could not be reached, and in narrow gaps and corners of equipment and the like. As described above, leaving a portion that is not partially sterilized even when sterilized on a very wide surface has reduced the sterilizing effect by half.

Accordingly, an object of the present invention is to provide a sterilizer capable of uniformly and reliably sterilizing even high places that cannot be reached, narrow gaps and corners of equipment and the like.

[0006]

To achieve the above object, the present invention provides a sterilizing apparatus for sterilizing a telescopic radiating member having a radiating section for radiating ultraviolet and / or ozone gas having a bactericidal action at its tip. The main body is provided.

Further, an ultraviolet lamp for radiating ultraviolet light having a germicidal action is provided at a radiation portion of the radiation member.

[0008] Further, an ultraviolet lamp for radiating ultraviolet rays for generating ozone gas is provided in the base of the radiating member housed in the sterilizer main body, and the ozone gas generated by the ultraviolet lamp is radiated from the radiating section of the radiating member. And a blower member for circulating the air is provided.

Further, an ultraviolet lamp for radiating ultraviolet rays having a sterilizing action and an ozone gas generating action is provided at a radiating portion of the radiating member.

The radiating member is characterized in that its outer diameter gradually decreases as it goes to the tip.

[0011]

FIG. 1 shows a sterilizing apparatus according to a first embodiment of the present invention. In the drawing, reference numeral 1 denotes a sterilizing apparatus, 2 denotes a sterilizing apparatus main body, and 3 denotes a sterilizing apparatus main body 2 having a base. , A radiating hollow radiating member whose outer diameter is gradually reduced toward the tip, 4 is a radiating portion formed at the tip of the radiating member 3 for irradiating ultraviolet rays, and 5 is a mixture of argon gas and mercury vapor. An ultraviolet lamp filled with an ultraviolet radiation gas or an ultraviolet radiation gas mainly composed of xenon and housed in the radiation portion 4, a cover 6 made of a material that transmits ultraviolet light, for example, glass or synthetic resin, and covering the ultraviolet lamp 5 , 7
Turns on the ultraviolet lamp 5 provided on the sterilizer main body 2.
A power switch 8 for turning off the light is a timer switch for setting the lighting time of the ultraviolet lamp 5 stepwise.

The radiating member 3 includes a first-stage cylinder 3a, a second-stage cylinder 3b, and a third-stage cylinder 3b from the base disposed in the sterilizer main body 2.
By gradually reducing the outer diameter of the cylindrical body 3c of the third stage and the radiating portion 4 in four steps, the cylindrical body 3c of the third stage is provided in the radiating portion 4,
The second-stage cylinder 3b becomes the third-stage cylinder 3c, the first-stage cylinder 3a becomes the second-stage cylinder 3b, and finally the first-stage cylinder 3a becomes the sterilizer main body 2 And is compactly folded as shown in FIG.

A drive circuit such as an inverter for driving the ultraviolet lamp 5 in the radiating section 4 and a power supply (not shown) such as a battery are housed in the sterilizing apparatus main body 2. Appropriate conductors (not shown) for connecting the ultraviolet lamp 5 to a drive circuit and the like are provided.

When the sterilizing apparatus 1 of the present invention is used, the radiation member 3 is extended to bring the radiation section 4 close to a desired position, and the power switch 7 is pressed, so that the ultraviolet lamp 5 is depressed.
Emits ultraviolet light having a wavelength of 254 nm, and sterilizes the surrounding area. When it is desired to irradiate ultraviolet rays for a certain period of time, the radiation section 4 is set, the lighting time is set by the timer switch 8, and the power switch 7 is turned on. This can prevent the battery from being consumed due to forgetting to turn off the power switch.

FIG. 3 shows a sterilizer according to a second embodiment of the present invention. In this sterilizer 1, ultraviolet rays having a wavelength of 185 nm are radiated to the base of the radiation member 3 in the sterilizer main body 2. And an ultraviolet lamp 9 for generating ozone gas by acting on oxygen in the air.
A blower member 10 for taking in outside air into the sterilizer main body 2 is disposed below the airbag. Further, by forming a radiating portion 12 having a ventilation portion 11 formed of a number of slits and a net at the tip of the radiating member 3, the air in the air introduced by the blowing member 10 into the sterilization apparatus main body 2 is irradiated with ultraviolet rays. The ultraviolet light of the lamp 9 acts to generate ozone gas, and the ozone gas is carried to the radiating section 12 and radiated from the ventilation section 11. 1 in the figure
Reference numeral 3 denotes a driving circuit such as an inverter for driving and lighting the ultraviolet lamp 9. Reference numeral 14 denotes a lamp support for holding the ultraviolet lamp 9.
A ventilation hole 15 is formed to allow the air delivered by the air outlet 0 to pass through. Other configurations are the same as those in the first embodiment.

In the sterilizer according to the second embodiment,
Since the radiating part 12 inside the radiating member 3 and the radiating part 12 at the tip end are in a hollow state in which neither an ultraviolet lamp nor a conducting wire is present, the radiating member 3 can be made thinner and longer. It is possible to sterilize with ozone gas even at a considerably high place such as the upper surface of a cupboard or a narrow gap.

FIG. 4 shows a sterilizer according to a third embodiment of the present invention. In this sterilizer 1, outside air is introduced into the sterilizer main body 2 at the base of the radiation member 3 in the sterilizer main body 2. Radiating member 12 having a ventilation portion 11 formed of a number of slits and a net at the tip of radiating member 3 and acting on oxygen in the air to generate ozone gas therein. An ultraviolet lamp 16 for irradiating ultraviolet rays having a wavelength of 185 nm and ultraviolet rays having a sterilizing action of 254 nm is provided. The ventilation part 11
The sterilizing ultraviolet rays are radiated from the ultraviolet lamp 16 from the slits and the net, and the ultraviolet lamp 16
Ozone gas generated by the action of ultraviolet rays is also emitted.
As a result, a synergistic sterilizing effect can be obtained by irradiation with ultraviolet light having a sterilizing action and ozone gas having a sterilizing action. Other configurations are the same as in the above-described second embodiment. Further, the blowing member 10 is not an essential component, and even when the blowing member 10 is omitted from the sterilization apparatus 1 of the present embodiment, the oxygen around the ultraviolet lamp 16 is ozonized, so that it is substantially the same. The effect of is obtained.

It is also conceivable to combine the second embodiment and the third embodiment described above. This is to accommodate an ultraviolet lamp for radiating ultraviolet light for sterilization in the radiating portion at the tip of the radiating member 3. An ultraviolet lamp for generating ozone gas is disposed at the base of the radiation member 3 in the sterilization apparatus main body 2. Although the number of parts is increased, the function of the ultraviolet lamp is shared between ultraviolet radiation and ozone gas generation. An excellent radiation effect of ultraviolet light for sterilization and generation of ozone gas can be obtained.

Although not particularly shown, the safety switch in each of the above-described embodiments is not set so as to perform a sterilizing action when the radiating member 3 is stored in the sterilizing apparatus main body 2, so that the power switch 7 is not used. It may be configured not to be turned on. This eliminates the possibility that the power switch is turned on by mistake and the ultraviolet lamp is turned on during carrying.

[0020]

As described above in detail, the sterilizing apparatus of the present invention is provided with a telescopic radiating member having a radiating portion for radiating ultraviolet rays and / or ozone gas having a sterilizing action at the distal end portion in the sterilizing apparatus main body. By doing so, it is possible to extend the radiating member and radiate ultraviolet rays and / or ozone gas from the radiating portion at the tip of the radiating member at the time of sterilization, thereby making it impossible to access high places, narrow gaps and corners of equipment etc. It is possible to preferably sterilize a portion that was difficult with a conventional sterilizing apparatus, and furthermore, when not in use, fold the radiating member inside the sterilizing apparatus body to make it compact and portable.

Further, by disposing an ultraviolet lamp having a germicidal action on the radiating portion of the radiating member, it is possible to access a high place where it cannot be reached,
It is possible to preferably sterilize a portion that is difficult with a conventional sterilizing apparatus such as a narrow gap or a corner portion of a device or the like by using ultraviolet rays having a sterilizing action.

Further, an ultraviolet lamp for radiating ultraviolet rays for generating ozone gas is provided in the base of the radiating member housed in the sterilizer main body, and the ozone gas generated by the ultraviolet lamp is radiated from the radiating section of the radiating member. By disposing the blower member for irradiating, it becomes possible to dispose the ultraviolet lamp at the base of the radiating member and make the tip of the radiating member hollow, thereby making the radiating member thinner and longer. Even if the gap is extremely narrow, the radiation portion of the radiation member can be inserted and the ozone gas can be radiated to easily sterilize.

Further, by disposing an ultraviolet lamp which emits ultraviolet rays having a germicidal action and an ozone gas generating action at the radiating portion of the radiating member, the irradiation of ultraviolet rays having a germicidal action and the ozone gas having a germicidal action are synergistic. A high sterilization effect is obtained, which is even more preferable.

Also, the radiating member gradually narrows its outer diameter as it goes to the tip, so that the radiating portion at the tip for radiating ultraviolet rays and / or ozone gas becomes narrower, and narrow gaps and corners of equipment and the like. For example, it becomes easy to insert a radiating portion into the device and sterilize it.
