Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a disposable dust collection filter for a vacuum cleaner.

[Background of the invention]

As a result of recent analysis of garbage in urban areas, a large number of woolly mites have been found, and along with this, house mites, which are the natural enemies of woolly mites, are also appearing.

The reason for this is that as high-rise houses appear due to overcrowding in urban areas, the degree of airtightness of each room increases, and the proper indoor dryness and humidity control that has been achieved by natural building materials since ancient times breaks down. Therefore, it cannot be denied that the increased humidity of the tatami floor is a contributing factor.

By the way, it is said that the bodies and carcasses of woolly mites may be the cause of respiratory diseases such as asthma and Kawasaki disease. House mites also suck blood directly from the human body, causing swelling and itching.

However, when harmful microorganisms such as those mentioned above begin to appear, the function of a vacuum cleaner to collect these harmful microorganisms along with dust is no longer sufficient to simply collect dust as in the past. , it greatly suppresses the reproduction of dust mites and other harmful microorganisms that are collected during vacuum cleaner operation, and even if there are dust mites that escape from the vacuum cleaner body, they will be killed in a short period of time. The need for measures to reduce the number of people living in Japan is becoming an urgent issue.

Furthermore, if you collect mites in a bag-shaped dust collection filter for a vacuum cleaner and leave them for a long time, they will be removed if the bait is in the garbage, the humidity is 40% or more, and the upper limit of the temperature is around 50 degrees. It has been confirmed through experiments that a large amount of mites breed in the dust filter if there is one.

An object of the present invention was to take into consideration how a disposable dust collection filter for a vacuum cleaner is used during use and after the filter is replaced and after the garbage is thrown away. Once collected in a dust collection filter, the reproduction of harmful microorganisms such as house mites and woolly mites is greatly suppressed, and even if there are mites that escape from the dust collection filter, this can be prevented in a short period of time. In addition to killing the filter in time, it also maintains its germicidal effect even after the filter is removed from the vacuum cleaner and thrown away.
The dust collection filter for vacuum cleaners, which is excellent in terms of environmental hygiene, prevents dust mites and fungi from propagating in the garbage, while the vacuum cleaner itself can constantly restore the sterilization effect by replacing the disposable filter. Our goal is to provide the following.

[Summary of the invention]

Therefore, the feature of the dust collection filter for a vacuum cleaner according to the present invention is that a disposable bag-like filter that is detachably attached to the dust collection part of a vacuum cleaner is provided with an insect repellent of 1.23 g/m ² or more, The reason is that it contains an insecticide or a microorganism exterminating agent.

[Embodiments of the invention]

Hereinafter, the present invention will be explained based on one embodiment of FIGS. 1 to 5. FIG. 1 is a longitudinal sectional side view showing the overall internal structure of a vacuum cleaner incorporating a disposable filter 10 according to the present invention. , Figure 2 is the first
The figure shows a perspective view of the front lid device indicated by the reference numeral 6 and the bag-shaped dust collection filter 10 is taken out. FIG. 3 is a perspective view of the dust collector shown by the reference numeral 4 in FIG. FIG. 5 is an enlarged front view of the dust collecting filter 10, and FIG. 5 is a perspective view of FIG. 4.

In FIGS. 1 and 2, 1 is a main body case of the vacuum cleaner, 2 is a motor, 3 is a cord reel, 4 is a dust collector, 5 is a dust remover, and 6 is a front lid device.

The main body case 1 has a handle 7 at its upper part, casters 8 and wheels 9 at its lower part, and an indicator 11 at the front of the upper part which displays the clogging of the dust collection filter 10, which will be described later. , and a clamp 12 for opening and closing the front lid device 6.

The motor 2 is located in a motor chamber 13 and is vibration-proofly supported by a front anti-vibration rubber 14 and a rear anti-vibration rubber 15, and an exhaust chamber 16 is provided at the rear of the motor chamber 13. Code 1 on reel 3
7 is wrapped.

As shown in FIG. 3, the dust collecting device 4 includes a sub dust collecting filter 18 (this
8 is built into the dust collecting device 4 as in the past so that it can be cleaned in time when the dust collecting filter 10 is on hand, that is, when there is no spare part) and the paper bag 10a of the dust collecting filter 10. , a paper bag support member 10b, a garbage discharge prevention lid 10c (FIGS. 2 to 5) that is integrally connected to the paper bag support member 10b, and a paper bag support member support portion 19 that supports the paper bag support member 10b. It is composed of a paper bag support member positioning pin 20 for positioning the paper bag support member 10b within the dust collector 4, a filter packing 21, and a net filter 22.

Further, the paper bag support member 10b has a dust suction port 23 (FIG. 3).
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 of the dust collecting device 4, and this dust removing device 5 removes dust from the dust collecting device 4.

In the above configuration, when the motor 2 is rotated and dust is sucked through the suction port (not shown), this dust is
The paper bag 10a passes through an extension pipe (not shown) and a hose (not shown), and passes from the hose port 24 of the front lid device 6 to the dust suction port 23 of the paper bag support member 10b.
collected inside. When the paper bag 10a is filled with collected garbage, the indicator 11 is activated.
Notify the user of a decrease in air volume.

As a result, the user turns off the power, presses the clamp 12 of the front lid device 6 to open the front lid device 6, and prevents the dust collection filter 10 set in the dust collector 4 from being discharged, as shown in FIG. Lid 10c,
Paper bag support member 10b integrally connected to this
The dust suction port 23 is covered with a lid to prevent dust from spilling out from the dust suction port 23 when disposing of trash. Then, holding both sides of the paper bag support member 10b, pull out the dust collecting filter 10 from the dust collecting device 4 and discarding it, and then set a new dust collecting filter 10 in the dust collecting device 4.

Therefore, in the present invention, the paper bag 10a constituting a part of the dust collection filter 10 contains an insect repellent and mite insecticide of 1.23 g/m ² or more, and the paper bag 10a contains an insect repellent and mite insecticide. By including the above-mentioned mites in the paper bag 10a, the frequency of contact between the insect repellent and the mite insecticide increases, so that the reproduction of mites in the paper bag 10a can be significantly suppressed. By applying insect repellent and mite insecticide at a rate of 1.23 g/m ² or more, a good mite killing rate can be obtained as shown below.

i.e. 50g of powdered feed prepared to a moisture content of 15%
and 0.5g of the test mites in a paper bag, mix well, and place the bag in a thermostat at a humidity of 80 to 100% (this paper bag was treated with insect repellent and mite insecticide commonly available in Japan). After 10 days, the paper bag was taken out, 0.1g of test mites were taken from the paper bag, and the number of living mites was counted under a microscope.The experiment was carried out three times each.The average results are shown in Figures 11 and 12. According to experiments, as shown in Figure 11, a particularly good mite killing rate can be obtained when the content of insect repellent and mite insecticide in the paper bag is 1.23 g/m2 ^or more. confirmed. In addition, the first
As shown in Figure 1, when the content of insect repellent and mite insecticide in a paper bag is 1.23g/ ^m2 , the mite killing rate is almost the same as when more insect repellent and mite insecticide are added. If the content of insect repellent and acaricide in paper bags is kept to 1.23g/ ^m2 , the amount of insect repellent and acaricide used can be saved while maximizing the mite killing rate, which is economical. It is true.

Moreover, FIG. 12 (months after opening of paper bag--mite killing rate characteristic diagram) shows the case of insecticide paper bag content (1.23 g/m ² ) based on the above results.

To explain the above points in more detail, we conducted a study using ticks, which are a typical example of harmful pests in urban areas, and found that the insecticide content per paper bag was 1.23g, as shown in Figure 11. / ^m2 or more, 90%
It was found that the above effective insecticidal effects can be obtained.

On the other hand, in the present invention, in actual commercialization, it has been determined that the effective duration of the mite insecticide is sufficient for 6 months with an insecticidal rate of 80% or more, as shown in FIG. 12. The reason for this is that the standard replacement period for disposable paper bags is two months, so the safety factor was tripled to six months. This six-month period is extremely effective, as it coincides with the high temperature, high humidity season in Japan, which is the breeding environment for ticks, from April to October.

As mentioned above, the reason why the lower limit of the insecticidal rate was set at 80% is that if the insecticidal rate was maintained at 80%, the increase in pests could be kept to a slight increase.

By the way, if the paper bag support member 10b that constitutes a part of the filter 10 is also impregnated with an insect repellent and mite insecticide, the mites collected in the paper bag 10a will try to escape from the dust suction port 23 by using the paper bag support member. 10b, the insect repellent and mite insecticide that has penetrated into the paper bag support member 10b will enter the body through the pores of the mite body and harmful microorganisms, and even if the mites crawl out from the paper bag 1.
Even if you escape outside of 0a, you will die within a short time, so you can rest assured that it will not harm the human body.

FIG. 6 is a longitudinal cross-sectional side view of the vicinity of the dust suction port 23 showing a second embodiment of the filter of the present invention. Among the paper bag support members 10b, 10b' is a paper bag support member that does not allow penetration of insect repellent and mite insecticides; '' is a paper bag support member impregnated with an insect repellent and mite insecticide.In other words, in this embodiment, the paper bag support member 10b' and the paper bag support member 10b'' are pasted together in two layers to prevent insects and mites. The paper bag 10a is bonded to the inside of the paper bag support member 10b'' which has been impregnated with a chemical agent.In other words, even though the above structure has no effect on the human body, some users do not want to touch it. In consideration of this, the paper bag support member 10 is directly touched when replacing the dust collection filter 10.
Care has been taken to prevent insect repellent and acaricide from penetrating into part b'.

In addition, in the embodiment shown in FIG. 6, the paper bag 10
A is impregnated with an insect repellent and mite insecticide, or the paper bag 10a is coated with an insect repellent and mite insecticide.

Also in the embodiments shown in FIGS. 7 to 10 below, the paper bag 10a is either impregnated with insect repellent and mite insecticide or coated with insect repellent and mite insecticide.

FIG. 7 is a longitudinal sectional side view of the vicinity of the dust suction port 23 showing the third embodiment of the filter of the present invention, and FIG. 8 is a view taken in the direction of arrow A in FIG. This is a paper bag support member on which a mixed adhesive glue 26 of an insect repellent and acaricide is applied to the joint surface with the paper bag 10a.

Similarly to the embodiment shown in FIG. 6, this embodiment also takes care not to apply insect repellent or mite insecticide to the surface of the paper bag support member 10b that is directly touched when replacing the dust filter 10. According to this embodiment, the number of paper bag supporting members is one less than that of the embodiment shown in FIG. 6, which contributes to a reduction in price.

FIG. 9 is a front view showing the fourth embodiment of the filter of the present invention, and FIGS. 10A, 10B, and 10C are dust suction ports each explaining the usage state of the dust collection filter 10 shown in FIG. 23, 10b is a paper bag support member of the dust collection filter 10, 10c is a dust discharge prevention lid that is integrally connected to the paper bag support member 10b, and 10b is a perspective view of the paper bag support member 10.
0b and the dust discharge prevention lid 10 are coated with or impregnated with insect repellent and mite insecticide. Reference numeral 27 denotes one side of the garbage discharge prevention lid 10c (in other words, when the garbage discharge prevention lid 10c is bent at the boundary with the paper bag support member 10b when disposing of garbage, the dust suction port 23 provided in the paper bag support member 10b 28 is one side of the garbage discharge prevention lid 10c (the side on which the adhesive 27 is applied).
Shows the protective sheet covering.

That is, in this embodiment, the surface of the adhesive 27 applied to the garbage discharge prevention lid 10c is covered with a removable protective sheet 28, and when the garbage is disposed of,
By peeling off the protective sheet 28 when folding the dust discharge prevention lid 10c and bonding the dust discharge prevention lid 10c to the paper bag support member 10b with the adhesive 27, the dust suction port 23 of the paper bag support member 10b is opened.

In summary, according to the present invention, the following effects can be achieved by taking the above-mentioned points into consideration.

That is, the present invention provides the following features: (1) A paper bag 10a that constitutes a part of the disposable dust collection filter 10 is coated with insect repellent and mite insecticide.
1.23g/m ² or more, and by including the insect repellent and mite insecticide in the paper bag 10a, the frequency of contact between the insect repellent and mite insecticide and the mites walking around in the paper bag 10a is high. Therefore, the reproduction of mites in the paper bag 10a can be significantly suppressed, and in particular, if the insect repellent and mite insecticide are applied at an amount of 1.23 g/m ² or more,
It was confirmed that a good mite killing rate as shown in the previous experimental results could be obtained.

(2) Furthermore, as a result of (1) above, even if some mites escape from the paper bag 10a, they can be killed in a short time.

(3) As a result of (1) and (2) above, even if the dust filter 10 that has collected dust is left in a trash can for a long period of time, the filter 10 maintains its sterilizing effect, and the dust mites inside the paper bag 10a remain. The seeds will not go into the trash can and reproduce.

(4) As shown in FIGS. 3 to 5, a foldable garbage discharge prevention lid 10c is connected to the paper bag support member 10b to close the dust suction port 23 of the paper bag support member 10b when disposing of garbage. By providing this, it is possible to prevent trash from accidentally spilling out from the dust suction port 23 when disposing of trash.

(5) As shown in FIG. 6, a paper bag support member 10b' that is not coated with insect repellent and mite insecticide and a paper bag support member 10 that is coated with insect repellent and mite insecticide.
By bonding the paper bag 10a to the inside of the paper bag support member 10b'' which has been laminated in two layers and treated with insect repellent and mite insecticide, the paper bag support member 10b' is directly touched when replacing the dust collection filter 10. Care was taken not to apply insect repellent or mite insecticides to this area. That is, even if it is said that there is no effect on the human body, considering the fact that some users do not want to touch it, insect repellent and Care was taken not to apply tick insecticides.

(6) As shown in FIGS. 7 and 8, insect repellent and mite insecticide are applied to the back side of the paper bag support member 10b, which is the side where the paper bag is attached, in the same manner as in the embodiment shown in FIG. , dust collection filter 1
Paper bag support member 10 that is directly touched when replacing paper bags
Care can be taken not to apply insect repellent or acaricide to the surface of the paper bag support member, and according to the embodiments shown in FIGS. 7 and 8, compared to the embodiment shown in FIG. The number of sheets required is one less, contributing to cost reduction.

(7) As shown in FIGS. 9 and 10, a surface portion of the garbage discharge prevention lid 10c that is integrally connected to the paper bag support member 10b and faces the dust suction port 23 of the paper bag support member 10b when disposing of garbage. By applying an adhesive 27 to the surface and covering the surface of the adhesive 27 with a removable protective sheet 28, the protective sheet 28 can be peeled off when folding the garbage discharge prevention lid 10c to prevent garbage discharge. The lid 10c is bonded to the paper bag support member 10b with an adhesive 27, and the paper bag support member 10b is attached.
The dust suction port 23 of the paper bag 10a can be sealed, and the effect is that by sealing the inside of the paper bag 10a, it is possible to reliably prevent dust mites once collected in the paper bag 10a from escaping out of the paper bag 10a. can do.

Although it is not a dust collection filter for a vacuum cleaner itself, it is published in Japanese Patent Application Publication No. 1973 entitled ``Method of sterilizing exhaust gas.''
Japanese Patent Publication No. 128677 discloses a technique for applying a disinfectant around the air passages within the vacuum cleaner body.

However, the problem that the technology described in the publication is trying to solve is the removal of germs from the air flow discharged from the vacuum cleaner body.

However, according to the technology described in the above-mentioned Japanese Patent Application Laid-Open No. 50-128677, the disinfectant applied around the air passages in the vacuum cleaner body can be used to remove dirt, especially hard dirt, that is sucked into the vacuum cleaner body at high speed. It is highly likely that the product will come into contact with the product and peel off, and if this is repeated over a long period of time, the effectiveness of the disinfectant, i.e., the disinfectant applied around the air passages within the vacuum cleaner body, in removing germs from the exhaust stream will be impaired. It is undeniable that it will happen.

On the other hand, if the disinfectant applied around the air passage inside the vacuum cleaner's main body peels off, or if the disinfectant is reapplied around the air passage on a regular basis, It is difficult for general users to apply disinfectant to narrow spaces such as air passages, and on the other hand, it is troublesome to outsource this work to a contractor each time.
This is troublesome and cannot be said to be a realistic method.

On the other hand, when a vacuum cleaner treated by the sterilization method described in the above-mentioned Japanese Patent Application Laid-open No. 128677/1983 is used, the following problems arise.

In other words, even when using the vacuum cleaner described in JP-A-50-128677, if the dust collection section becomes full of dirt, the dirt must be removed from the vacuum cleaner body and thrown away. However, since there is no barrier around garbage that has been discarded as described above (for example, the wall of a paper bag), pests such as mites that have survived in the garbage can easily crawl out to the surrounding area. be. In other words, in the conventional technology shown in Japanese Patent Application Laid-open No. 50-128677, the garbage that has filled up inside the vacuum cleaner body is removed from the vacuum cleaner body and is disposed of before being used for environmental hygiene, which is a pest control measure. There is still room for improvement in this respect, as the issue of protection is not yet recognized.

On the other hand, according to the present invention, house dust mites that are once collected on a bag-shaped dust collection filter by operating a vacuum cleaner,
It can greatly suppress the reproduction of harmful microorganisms such as woolly mites within the dust collection filter, and even if the mites escape from the dust collection filter, they can be killed in a short period of time. Re-contamination of the living environment with microorganisms can be prevented.

In addition, in each of the above-mentioned Examples, the case where an insect repellent and acaricide were used was illustrated, but a wide range of microbial insecticides having the same effect as this can be used.

[Effects of the Invention] The present invention is as described above, and the present invention was made in consideration of how to use a disposable dust collection filter for a vacuum cleaner, and after replacing the filter and disposing of garbage. According to the present invention, the reproduction of harmful microorganisms such as house mites and woolly mites once collected in the bag-shaped dust collection filter by vacuum cleaner operation is significantly suppressed, Furthermore, even if there are mites that escape from the dust collection filter, in addition to killing them in a short time, the sterilizing effect continues even after the filter is removed from the vacuum cleaner and thrown away. While preventing the growth of dust mites and fungi, the vacuum cleaner itself can always have its sterilizing effect restored by replacing the disposable filter. It is possible to provide a dust collection filter for a vacuum cleaner that prevents recontamination with mites and fungi in the living environment and is excellent in terms of environmental hygiene.
