Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposable dust filter for an electric vacuum cleaner and an electric vacuum cleaner using the filter.

[0002]

2. Description of the Related Art As a result of a recent analysis of garbage in urban areas, a large amount of Phytolacca cerevisiae have been generated, and along with this, house mites, which are natural enemies of Phytolacca cinerea, have also been generated.

The cause of this is that as high-rise houses emerge due to the overcrowding of urban areas, the degree of airtightness of each room has increased, and the appropriate adjustment of indoor dryness and humidity, which has been performed by natural building materials since ancient times, has failed. As a result, it cannot be denied that the increase in the humidity of the tatami floor is a factor.

By the way, it is also said that the insect bodies and carcasses of Aedes albopictus may cause Kawasaki disease and respiratory diseases such as asthma. In addition, house mite sucks blood directly from the human body and causes swelling and itching.

[0005]

However, when harmful microorganisms are generated as described above, the function of the electric vacuum cleaner which collects these harmful microorganisms together with the dust is also
As in the past, simply collecting dust is insufficient, and it greatly suppresses the reproduction of mites and other harmful microorganisms once collected by operating the vacuum cleaner, and even mites that escape from the vacuum cleaner body. Even if there are such species, it is an urgent task to take measures to bring them to death in a short time.

[0006] When mites are collected in a bag-like dust collecting filter for an electric vacuum cleaner and left for a long time, the food is in the garbage, the temperature is 40% or more, and the upper limit of the temperature is 50.
It has been confirmed by experiments that a large amount of mites propagate in the dust collecting filter if the degree is about the degree.

The present invention has been made in consideration of how to use the dust collecting filter for a disposable electric vacuum cleaner and after the filter is replaced and after the dust is thrown away. , Among harmful microorganisms such as house mites and mosquito mites that have once been collected on the bag-shaped dust collection filter by operating the vacuum cleaner, even if there are mites that escape from the dust collection filter, they will die in a short time. In addition to preventing a large amount of these mites from being propagated and performing sanitary waste treatment, the effect of the drug continues even after the filter is removed from the vacuum cleaner and the waste is thrown away. For the vacuum cleaner that is excellent in environmental hygiene, while preventing the growth of fungi, the vacuum cleaner itself can always regenerate the effect of the medicine by replacing the disposable filter. Dust filter and the filter
It is to provide the used vacuum cleaner.

It should be noted that although it is not a dust collecting filter for an electric vacuum cleaner itself, it is not disclosed in Japanese Patent Laid-Open No. Sho 50, entitled "Sterilizing Method of Exhaust Gas".
Japanese Patent Publication No. 128677 discloses a technique of applying a bactericide around the air passage in the electric vacuum cleaner body.

However, the problem to be solved by the technique described in the publication is to remove bacteria in the air stream discharged from the cleaner body.

However, the above-mentioned Japanese Patent Laid-Open No. 50-1286.
According to the technique described in Japanese Patent Publication No. 77, the disinfectant applied to the vicinity of the air passage in the cleaner body may come in contact with dust that has been sucked into the cleaner body at high speed, particularly hard dust, and peel it off. It is considered to be sufficient, and if this is repeated over a long period of time, it cannot be denied that the effect of removing germs in the exhaust gas flow by the disinfectant, that is, the disinfectant applied around the air passage in the cleaner body is impaired.

On the other hand, when the bactericide applied around the air passage in the cleaner body is peeled off, or periodically,
It is conceivable to reapply the germicide around the air passage, but it is difficult for a general user to apply the germicide to a narrow space such as the air passage inside the cleaner body,
On the other hand, it is troublesome to entrust this work to a contractor each time, and it is difficult to say that this is a practical method.

On the other hand, in the case of using the electric vacuum cleaner treated by the insecticidal method described in Japanese Patent Laid-Open No. 50-128677, there are also the following problems.

That is, even when the electric vacuum cleaner disclosed in Japanese Patent Laid-Open No. 50-128677 is used, when the dust collecting portion is full of dust, the dust is taken out from the main body of the vacuum cleaner. However, since the garbage thrown away as described above does not have a barrier object (for example, the wall of a paper bag) around it, pests such as mites that survive in the garbage can easily get around. There is a problem of crawling out. In other words, in the prior art disclosed in Japanese Patent Laid-Open No. 50-128677, the environment which is a countermeasure against harmful insects after the dust filled in the cleaner body is taken out from the cleaner body and discarded We are not aware of hygiene protection, and there is room for improvement in this respect.

On the other hand, according to the present invention, the reproduction of harmful microorganisms such as house mites, mosquito mites and the like once collected on the bag-shaped dust collecting filter by the operation of the vacuum cleaner is greatly suppressed, Furthermore, even if there are mites that escape from the dust collection filter, they can be killed in a short time, and recontamination of living environment with microorganisms can be prevented.

In the above examples, the case of using the insect repellent and the acaricide for mite was illustrated, but a microbial insecticide having an effect equivalent to this can be used.

[0050]

EFFECTS OF THE INVENTION According to the present invention, in addition to suppressing harmful microorganisms trapped in the dust collecting filter from propagating in the dust collecting filter and performing sanitary dust treatment, the filter is vacuum cleaner. Even after removing it from the bag and throwing away the trash, the effect of the drug is maintained and harmful microorganisms are prevented from propagating.On the other hand, in the vacuum cleaner itself, the effect of the drug can always be obtained by replacing the disposable filter. Can this
Depending on the replacement use cycle of the disposable filter
It is possible to prevent re-contamination of living environment with mites and fungi .
