Abstract

PURPOSE:To sharply suppress the breeding of captured noxious microorganisms and to annihilate them in a short time even if they escape by making a bag- shaped filter, whose dust collecting part is mounted freely in mounting and removal, contain moth-proofing agent, insecticide, or microorganisms expellent at specified value or more. CONSTITUTION:A paper bag 10a, which constitutes a dust collecting filter 10, contains moth-proofing or ticks-proofing agent of 1.23g/m or more, whereby for a genus of ticks walking about inside the paper bag 10a, the contact frequency with the moth-proofing and ticks insecticide becomes high, and breeding can be suppressed sharply. Moreover, if making moth proofing and ticks insecticide permeate the paper bag supporting member 10b of the filter 10 too, in case that a genenus of ticks being captured crawl out along the paper bag supporting member 10b seeking to escape, the moth-proofing and ticks insecticide enters the bodies of ticks and noxious microorganisms through pores, etc., so they can be annihilated in a short time.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Application of the Invention) The present invention relates to a dust collection filter for a vacuum cleaner, and more specifically, it is used to collect dust mites and other dust particles that are once collected on a bag-shaped dust collection filter during operation of the vacuum cleaner. It is an environmental hygiene product that can significantly suppress the reproduction of harmful microorganisms within the dust collection filter, and even if there are mites that escape from the dust collection filter, they can be killed in a short period of time. Regarding excellent dust collection filters for vacuum cleaners.

[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 housing has appeared due to urban overcrowding, the degree of airtightness of each room has increased, and the proper indoor dryness and humidity control that has been achieved by natural building materials since ancient times has collapsed, and as a result, It cannot be denied that increased humidity on 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. , a measure that greatly suppresses the reproduction of dust mites and other harmful microorganisms that are collected during vacuum cleaner operation, and even if some dust mites escape from the vacuum cleaner, they will be killed in a short period of time. The need for this has become an urgent issue.

In addition, if you collect mites in a bag-shaped dust collection filter for a vacuum cleaner and leave them for a long time, if the bait is in the garbage, the humidity is 40% or more, and the upper limit of the temperature is about 50 degrees. If there is, it has been confirmed through experiments that large mites breed in the dust filter.

The purpose of the present invention is to significantly suppress the propagation of house mites, woolly mites, and other harmful microorganisms that are once collected in the bag-shaped dust collecting filter by vacuum cleaner operation, and furthermore, even if the dust collecting filter Even if some mites escape, they can be killed in a short time. The purpose of the present invention is to provide a dust collection filter for a vacuum cleaner that is excellent in terms of environmental hygiene.

[Summary of the invention]

Therefore, the features of the dust collection filter for a vacuum cleaner according to the present invention are that the bag-shaped filter that is detachably attached to the dust collection part of the vacuum cleaner contains an insect repellent of 1.23 g/rrr 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 the filter 10 of the present invention, and FIG. The figure is a perspective view of the front lid device shown in FIG. 1 with the reference numeral 6 opened and the bag-shaped dust collection filter 10 taken out, and FIG. 4 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 that indicates the clogging of the dust 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. A cord 17 is wound on the reel 3.

As shown in FIG. 3, the dust collector 4 is equipped with a sub-dust filter 18 (this sub-dust filter 18 can be used to clean the dust filter 10 on hand, in other words, when there is no spare part). ), the paper bag 10a of the dust collection filter 10, the paper bag support member 10b, and the paper bag support member 10.
The dust discharge prevention lid 10c (FIGS. 2 to 5) that is integrally connected to the paper bag supporting member 10b, the paper bag supporting member support part 19 that supports the paper bag supporting member 10b, and the paper bag supporting member 10b are placed in the dust collector 4. It is composed of a paper bag support member positioning pin 20 for positioning, a filter packing 21, and a net filter 22.

Further, the paper bag support member 10b has a dust suction port 23.
(FIG. 3) 5 This dust suction port 23 is connected to a hose port 24 of the front lid device 6 via a seal packing 25.

Further, a well-known dust removal device 5 is provided at the rear of the dust collector 4.
is provided, and this dust removal device 5 removes dust from the dust collection bag @4.
Remove dust.

In the above configuration, when the motor 2 is rotated and dirt is sucked in from the suction port (not shown), this dirt passes through the extension pipe (not shown) and the hose (not shown), and then passes through the hose of the front cover device 6. From the opening 24 of the paper bag support member], the dust passes through the dust suction opening 23 of Ob and is collected in the paper bag 10a. When the paper bag 10a is full of collected garbage, indicator 1
1 is activated and notifies the user of the 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, as shown in FIG. 2, and prevents the dust collection filter 10 set in the dust collector 4 from being discharged. M10c is folded at the boundary of the paper bag supporting member 10b which is integrally connected thereto, and the dust suction port 23 is covered to prevent dust from spilling out from the dust suction port 23 when disposing of trash. After that, holding both sides of the paper bag support member 10b, pull out the dust collection filter 10 from the dust collection device 4 and throw it away, and then replace it with a new dust collection filter 1.
0 in the dust collector 4.

According to the present invention, insect repellent and mite insecticide are applied to the paper bag 10a that constitutes a part of the dust collection filter 10.
Contains 23g/rrr or more, paper bag 10
By including the insect repellent and mite insecticide in the paper bag 10a, the frequency of contact between the insect repellent and the mite insecticide and the mites roaming within the paper bag 10a increases, thereby significantly suppressing the reproduction of mites within the paper bag 10a. In particular, when the amount of the insect repellent and mite insecticide is 1.23 g/rn' or more, the following good mite killing rate can be obtained.

That is, 50 g of powdered feed prepared to have a moisture content of 15% and 0.5 g of test mites were placed in a paper bag and mixed well.
Store the paper bag (this paper bag has been treated with insect repellent and mite insecticide, which is generally commercially available in Japan) in a thermostatic chamber with a humidity of 80 to 100%. After 10 days, remove the paper bag and remove the sample mites from inside the paper bag. Figure 11.12 shows the average result of three experiments in which the number of living mites was counted under a microscope using .1g of mites.According to the experiment,
As shown in Figure 11, when the content of insect repellent and mite insecticide is 1.23 g/m or more per paper bag,
It was confirmed that a particularly good mite killing rate could be obtained. Furthermore, as shown in Fig. 11, when the content of insect repellent and mite insecticide in the paper bag is 1.23 g/m2,
The mite killing rate is almost the same as when insect repellent and mite insecticide are added.

Therefore, if the content of insect repellent and mite insecticide in a paper bag is kept to 1.23 g/m'', the amount of insect repellent and mite insecticide used can be saved while maximizing the mite killing rate, making it economical. It is true.

In addition, Fig. 12 (months after opening the paper bag - mite killing rate characteristic diagram) shows the insecticide paper bag content - t (1
, 23 g/m").

By the way, if an insect repellent and mite insecticide is also impregnated into the paper bag support member fob that constitutes a part of the filter 10, the mites collected in the paper bag 10a will be absorbed into the dust suction port 23.
When the paper bag support member 10b is crawled out in an attempt to escape from the paper bag support member 10b, the insect repellent and mite insecticide that has penetrated into the paper bag support member 10b enters the body through the pores of the mite body and harmful microorganisms. Even if mites are in a 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 vertical sectional side view of the vicinity of the dust suction port 23 showing a second embodiment of the filter of the present invention.
Of b, 10b' is a paper bag support member impregnated with insect repellent and mite insecticide, and 10b' is a paper bag support member impregnated with insect repellent and mite insecticide. In other words, 1
This embodiment includes one paper bag support member 10b' and a paper bag support member 10.
A paper bag 10a is bonded to the inside of a paper bag support member 10b' which is laminated in two layers and impregnated with an insect repellent and acaricide. That is, the above structure takes into consideration that some users do not want to touch the part of the paper bag support member 10b' that is directly touched when replacing the dust filter 10, even if it has no effect on the human body. It is designed to prevent the penetration of insect repellent and mite insecticides.

In the embodiment shown in FIG. 6, one paper bag 10a includes:
Has it been infiltrated with insect repellent and acaricide?

Alternatively, insect repellent and mite insecticide are applied inside the paper bag 10a.

Also, in the embodiments shown in FIGS. 7 to 10 below,

Similarly to the embodiment shown in FIG. 6, this embodiment also has a paper bag support member 10b that is directly touched when replacing the dust filter 10.
According to this embodiment, compared to the embodiment shown in FIG. 6, the number of paper bag support members is one less, and the price is reduced by one. This contributes to the reduction of

FIG. 9 is a front view showing the fourth embodiment of the filter of the present invention, and FIGS.
It is a perspective view of the vicinity of the dust suction port 23 for explaining the usage state of the dust collecting filter 10 shown in the figure, in which 10b is a paper bag support member of the dust collection filter 10, and 10c is integrally connected with the paper bag support member 10b. Showing the garbage discharge prevention lid,
The paper bag supporting member fob and the garbage discharge prevention lid 10c 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 fob 28 indicates a protective sheet that covers one surface (the surface to which the adhesive 27 is applied) of the dust discharge prevention lid 10c.

That is, in this embodiment, the dust discharge prevention lid 10c
The surface of the applied adhesive 27 is covered with a removable protective sheet 28 when disposing of the garbage.

When folding the dust discharge prevention Wt10c, the protective sheet 28 is peeled off and the dust discharge prevention lid 10c is bonded to the paper bag support member 10b with an adhesive 27, thereby sealing the dust suction port 23 of the paper bag support member 10b. The effect is that by sealing the inside of one paper bag 10a, it is possible to reliably prevent the mites once collected in the paper bag 10a from escaping to the outside of the paper bag 10a.

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: (1) a paper bag 10a that constitutes a part of the dust collection filter 10;
The paper bag 10a contains an insect repellent and mite insecticide of 1.23 g or more per bag, and by containing the insect repellent and mite insecticide in the paper bag 10a, the insect repellent and mites that roam inside the paper bag 10a are eliminated. Due to the increased frequency of contact with pesticides.

The reproduction of mites in the paper bag 10a can be significantly suppressed, and in particular, the insect repellent and mite insecticide of 1.23
It was confirmed that a good mite killing rate as shown in the previous experimental results can be obtained when the amount is higher than g/rrl'.

(2) Furthermore, as a result of the above (1), 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 containing garbage is left in the trash can for a long time, the mites inside the paper bag 10a will come out and breed inside the trash can. There's nothing to do.

(4) As shown in FIGS. 3 to 5, one paper bag support member 10
When disposing of garbage, the paper bag support member 10b is integrated with b.
By continuously providing a bendable dust discharge prevention lid 10c that closes the dust suction port 23, it is possible to prevent dust from accidentally spilling out from the dust suction port 23 when disposing of garbage.

(5) As shown in FIG. 6, a paper bag support member 10b' to which no insect repellent or mite insecticide has been applied and a paper bag support member 10b' to which an insect repellent or mite insecticide has been applied are pasted together in two layers to form an insect repellent and mite insecticide. By joining the paper bag 10a to the inside of the paper bag support member 10b' treated with insecticide,
Care was taken not to apply insect repellent or mite insecticide to the portion of the paper bag support member 10b' that is directly touched when replacing the dust filter 10. That is, in consideration of the fact that some users do not want to touch it, even if it is said that it has no effect on the human body, the part of the paper bag support member 10b' that is directly touched when replacing the dust collection filter 10 is provided with insect repellent and mite killer. Care was taken not to apply chemicals.

(6) As shown in FIGS. 7 and 8, it is located on the back side of the paper bag support member 10b, which is the paper bag attachment side.

By applying the insect repellent and mite insecticide, care is taken not to apply the insect repellent and mite insecticide to the surface of the paper bag support member 10b that is directly touched when replacing the dust collection filter 10, as in the embodiment shown in FIG. According to the embodiments shown in FIGS. 7 and 8, the number of paper bag supporting members is one less than that of the embodiment shown in FIG.

Contributes to lower prices.

(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. By bonding the lid 10c to the paper bag support member 10b with an adhesive 27, the dust suction port 23 of the paper bag support member 10b can be sealed. It is possible to reliably prevent the mites once collected in the paper bag 10a from escaping to the outside of the paper bag 10a.

Although it is not a dust collection filter for vacuum cleaners, it is published in Japanese Patent Application Laid-Open No. 50-12867 entitled "Method for sterilizing exhaust gas".
Publication No. 7 discloses a technique of applying a disinfectant around the air passage in 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 passage in the vacuum cleaner body is used to remove dirt, especially hard dirt, that is sucked into the vacuum cleaner body at high speed. It is highly likely that the products will come into contact 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. I can't deny it.

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, Like an air passage.

It is elegant for ordinary users to apply disinfectant to small spaces, but on the other hand, it is troublesome and troublesome to outsource this work to a contractor each time, and it is not a realistic method. Hard to say.

On the other hand, when using a vacuum cleaner treated by the sterilization method described in JP-A-50-128677,
There are also problems such as:

That is, even when using the vacuum cleaner described in JP-A-50-128677, if the dust collection section is 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 is discarded as described above (for example, the wall of a paper bag), pests such as mites that survive inside the garbage can easily crawl out to the surrounding area. There is. In other words, in the conventional technology shown in Japanese Patent Application Laid-Open No. 50-128677, the dust that has become full inside the vacuum cleaner body is removed from the vacuum cleaner body, and after being thrown away, the environmental protection There is still room for improvement in this respect as there is no awareness of hygiene protection.

On the other hand, according to the present invention, house dust mites are collected once in 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 some 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.

〔Effect of the invention〕

The present invention is as described above, and according to the present invention, it is possible to significantly suppress the reproduction of harmful microorganisms such as house mites and woolly mites once collected by vacuum cleaner operation within the dust collection filter, and furthermore, even if the dust mites are To provide a dust collecting filter for a vacuum cleaner which is excellent in terms of environmental hygiene and can kill mites in a short time even if they escape from the dust filter.
