Abstract

PURPOSE:To obtain a dust collection filter for a vacuum cleaner which is excellent in environmental health by treating the inside of the bag member for collecting dirts with a chemical agent to suppress the breeding of microorganisms, leaving the bag support member non-treated. CONSTITUTION:A disposable bag-shaped filter 10 has a paper bag 10a for housing dirts collected and a paper bag support member 10b having the paper bag mounted on a dust collection part free to load or unload. The inside of the paper bag 10a undergoes a treatment with a chemical agent to suppress the breeding of microorganisms but the paper bag support member 10b is left non- treated. As a result, the frequency of contact increases between harmful microorganisms such as ticks walking therein 10a and the chemical agent, and the chemical agent enters into the body of the harmful microorganisms through pores or the like to suppress the breeding of the harmful microorganisms in the paper bag 10a significantly. Thus, even if there are the harmful microorganisms such as ticks escaping from the dust collection filter 10, they can be killed in a short time.

Description

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.

[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-shaped dust collecting filter for an electric vacuum cleaner and left for a long time, the food is in the garbage, the humidity 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 view of the suppression of the propagation of harmful microorganisms during use of an electric vacuum cleaner and further after discarding dust, and the main purpose of the present invention is to apply the bag-like dust collecting filter once by operating the vacuum cleaner. Significantly suppresses the reproduction of harmful microorganisms such as house mites and mosquito mites that have been collected in the dust filter, and even if there are mites that escape from the dust filter, they will die within a short time. In addition to tightening, it also prevents the growth of mites and fungi after removing the filter from the vacuum cleaner and throwing away the trash.
We provide a dust collection filter for electric vacuum cleaners that is excellent in environmental hygiene and can regenerate the effect of suppressing the growth of harmful microorganisms by the dust collection filter even for the vacuum cleaner itself that has re-installed the dust collection filter after throwing away dust. To do.

[0008]

The above object is to provide a cleaner body having an electric blower, a cord reel, a dust collecting portion, and the like.
A disposable bag filter disposed in the dust collecting part, wherein the disposable bag filter detachably mounts a bag member for accommodating collected dust and the bag member on a dust collecting part of an electric vacuum cleaner. This is achieved by having a bag supporting member, without performing a chemical treatment on the bag supporting member, and by performing a chemical treatment for suppressing the growth of microorganisms inside the bag member in which dust is collected.

[0009]

According to the present invention, when the motor is rotated to suck dust from the suction port, the dust passes through the extension tube and the hose, passes through the dust suction port of the bag supporting member of the disposable bag-shaped filter, and is discharged to the inside. It is collected in a bag member that has been treated with a chemical that suppresses the growth of microorganisms.

When the bag member is filled with the collected dust, the indicator operates to notify the user that the air volume is low.

As a result, the user turns off the power, pulls out the dust collecting filter set in the dust collecting device from the dust collecting device and discards it, and then sets a new dust collecting filter in the dust collecting device.

The body case 1 has the handle 7 on the upper portion thereof, the casters 8 and the wheels 9 on the lower portion, and the clogging of the dust collecting filter 10 described later is displayed on the upper front side. It has an indicator 11 and a clamp 12 for opening and closing the front lid device 6.

The motor 2 is located in the motor chamber 13,
An anti-vibration support is provided by the front anti-vibration rubber 14 and the rear anti-vibration rubber 15, an exhaust chamber 16 is provided at the rear of the motor chamber 13, and a cord 17 is wound around the cord reel 3.

As shown in FIG. 3, the dust collecting device 4 includes a sub dust collecting filter 18 (this sub dust collecting filter 18
Is incorporated in the dust collecting device 4 as in the conventional case so that the dust collecting filter 10 can be hand-held, that is, when there is no spare portion), and the paper bag 10a of the dust collecting filter 10 , A paper bag supporting member 10b, and a dust discharge prevention cover 10c integrally provided with the paper bag supporting member 10b.
(FIGS. 2 to 5), a paper bag supporting member supporting portion 19 for supporting the paper bag supporting member 10b, and a paper bag supporting member positioning pin 20 for positioning the paper bag supporting member 10b in the dust collector 4.
, Filter packing 21, and net filter 22
It is composed of and.

The paper bag supporting member 10b has a dust suction port 23 (FIG. 3).
Is connected to the hose port 24 of the front lid device 6 via a seal packing 25.

Further, a well-known dust removing device 5 is provided at the rear portion of the dust collecting device 4, and the dust removing device 5 removes dust from the dust collecting device 44.

In the above structure, the motor 2 is rotated,
When you suck in dust from the mouthpiece (not shown),
Through an extension tube (not shown) and hose (not shown),
From the hose port 24 of the front lid device 6 through the dust suction port 23 of the paper bag supporting member 10b, it is collected in the paper bag 10a. When the paper bag 10a is filled with the collected dust, the indicator 11 operates to notify the user of the decrease in air volume.

As a result, the user turns off the power, pushes the clamp 12 of the front lid device 6 to open the front lid device 6 as shown in FIG. 2, and the dust of the dust collecting filter 10 set in the dust collecting device 4 is removed. The discharge prevention lid 10c is folded at the boundary of the paper bag supporting member 10b that is integrally provided with the discharge prevention lid 10c, and the dust suction opening 23 is covered so that dust does not spill from the dust suction opening 23 when the dust is discarded.

After that, after holding the both sides of the paper bag supporting member 10b and pulling out and discarding the dust collecting filter 10 from the dust collecting device 4, a new dust collecting filter 10 is installed.
Set to.

In this embodiment, however, the paper bag 10a in which dust is collected is treated with a chemical agent that suppresses the growth of microorganisms, and the paper bag 10a is thus treated with a chemical agent that suppresses the growth of microorganisms. By performing the treatment, the frequency of contact between the harmful microorganisms such as mites walking in the bag member and the drug increases, so the harmful microorganisms that have come into contact with the drug enter the drug into the body through the pores, etc. The reproduction of harmful microorganisms inside the plant can be significantly suppressed, and even if there are harmful microorganisms such as mites that escape from the dust collection filter, they can be killed in a short time. Recontamination with environmental microorganisms can be prevented.

Also, even though it may be said that the medicine does not affect the human body, the portion of the paper bag supporting member 10b which is directly touched by the hand when exchanging the dust collecting filter 10 in consideration of the direction that the user does not want to touch it. By not applying a medicine to the filter, the user of the present invention can use the filter 10 of this kind more easily than the case where the medicine is applied to the portion of the paper bag supporting member 10b.

Further, by not applying the medicine to the portion of the paper bag supporting member 10b, the amount of the medicine used can be reduced correspondingly, which is economical and contributes to the cost reduction.

The harmful microorganisms such as mites are not contained in the paper bag 10.
Since there is a high frequency of contact with the drug while walking in a, it is possible to apply the drug to the paper bag support member 10b without
There is no significant impact that cannot be evaluated as a product.

Furthermore, by treating the inside of the paper bag 10a with a chemical agent that suppresses the growth of microorganisms, it is possible to prevent the chemical agent from directly touching the user's hand, and the entire surface of the paper bag 10a is exposed to the chemical agent. The amount of the drug used can be reduced as compared with the case of applying.

As a reference, 50 g of powdered feed prepared to have a water content of 15% and 0.5 g of sample mites were placed in a paper bag, mixed well, and placed in a thermostatic chamber having a humidity of 80 to 100% (the paper bag Was treated with insect repellents and acaricides that are commercially available in Japan.) 10 days later, the paper bag was taken out, and 0.1 g of the sample mite was taken from the paper bag, and a living mite was observed under a microscope. 6 and FIG. 7 show the average results obtained by conducting the experiment of counting the number of 3 times each, and according to the experiment, as shown in FIG. It was confirmed that particularly good mite insecticidal rate was obtained when the amount was 0.23 g / m ² or more.

Further, FIG. 7 (months after opening the paper bag-characteristic diagram of mite insecticidal rate) shows the case of the paper bag content of the insecticide (1.23 g / m ² ) based on the above results.

By the way, Japanese Patent Laid-Open Publication No. 50-128677 entitled "Sterilizing Method of Exhaust", which is not the dust collecting filter itself for the electric vacuum cleaner, applies a bactericidal agent around the air passage in the main body of the electric vacuum cleaner. Techniques for doing so are disclosed.

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, when the electric vacuum cleaner treated by the insecticidal method described in Japanese Patent Laid-Open No. 50-128677 is used, there are 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 and mosquito mites once collected on the bag-shaped dust collecting filter by the vacuum cleaner is greatly suppressed in the dust collecting filter. 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 insect repellents and acaricides was illustrated, but a microbial insecticide having an effect equivalent to this can be used.

[0037]

The present invention is as described above, and the present invention has been made in consideration of the usage of the dust collecting filter for the disposable vacuum cleaner and the usage after the filter is replaced and after the dust is discarded. According to the present invention, the house dust mites once collected in the bag-shaped dust collecting filter by the vacuum cleaner operation, greatly suppresses the reproduction of harmful microorganisms such as mosquito mites in the dust collecting filter, and further Even if there are mites that escape from the dust collection filter, in addition to letting them die in a short time, the effect of the drug continues even after the filter is removed from the vacuum cleaner and discarded, and the mites are removed from the dust. While preventing the growth of bacteria and fungi, the effect of the drug can be revived by replacing the disposable filter on the vacuum cleaner itself. To prevent re-contamination in the mites and fungi of the living environment by the use cycle, excellent on the environment and health, it is possible to further obtain ease of use, even excellent dust collecting filter for the vacuum cleaner in terms of economy.
