Field of the Invention The present invention relates to a dust-collecting filter for a disposable vacuum cleaner and a vacuum cleaner using the filter. 2. Description of the Related Art As a result of analyzing garbage in urban areas in recent years, a large number of mites have been generated, and along with this, house mites, which are natural enemies of the mites, have also been generated. [0003] The cause is that, as high-rise houses appear due to overcrowding in urban areas, the degree of sealing of each room increases, and the moderate indoor dryness and humidity adjustment that has been played by natural building materials since ancient times collapsed. As a result, it cannot be denied that the increase in the humidity of the tatami floor is one of the causes. [0004] By the way, it is said that the insect body and dead body of the red mite, Acarina mites, may cause respiratory diseases such as asthma and Kawasaki disease. In addition, house mites suck blood directly from the human body, causing swelling and itching. [0005] However, when the harmful microorganisms are generated as described above, the function of the vacuum cleaner that collects these harmful microorganisms together with the garbage is also different from the conventional one. It is not enough to simply collect garbage, and ticks once collected by vacuum cleaner operation,
There is an urgent need to take measures to significantly suppress the propagation of other harmful microorganisms, and even to kill any mites that escape from the main body of the vacuum cleaner in a short time. When mites are collected in a bag-shaped dust collecting filter for a vacuum cleaner and left for a long time, the bait is in the garbage, the humidity is 40% or more, and the upper limit of the temperature is 50. Experiments have confirmed that a large amount of ticks proliferate in the dust filter when the temperature is on the order of degrees. The present invention has been made in consideration of how to use a dust collection filter for a disposable vacuum cleaner, and how to use the dust collection filter after replacing the filter. Among the harmful microorganisms such as house mites and Acarina mites once collected in the bag-shaped dust collecting filter by vacuum cleaner operation, even if there are mites that escape from the dust collecting filter, they are killed in a short time. In addition to preventing the mass propagation of these mites and treating garbage in a sanitary manner, in addition to removing the trash by removing the filter from the vacuum cleaner, the effect of the medicine is maintained, and ticks and ticks are removed from the trash. For vacuum cleaners that are environmentally friendly, prevent the growth of fungi while maintaining the effect of medicine by replacing disposable filters. An object of the present invention is to provide a dust collecting filter and a vacuum cleaner using the filter. Means for Solving the Problems A dust collecting filter for a vacuum cleaner according to the present invention includes a bag member for collecting dust taken in by a suction airflow of an electric blower, and a suction port portion of the bag member. A disposable dust collection filter which is attached to a dust collection unit of a vacuum cleaner and is detachably attached to the bag support member having a dust suction port attached to the bag member. It is characterized by the following. In addition, the vacuum cleaner according to the present invention includes a suction body that sucks dust, and a dust collection chamber in which dust sucked through the suction body by an electric blower provided in the cleaner body is collected. The dust collecting chamber includes a bag supporting member mounting portion, and includes a bag member that collects dust taken in by an airflow of the electric blower, and a bag supporting member that is attached to a suction port of the bag member and has a dust suction port. As a member, a disposable bag-shaped dust collecting filter in which the bag member has been subjected to a treatment for exterminating microorganisms or the like is attached to the bag supporting member mounting portion. According to the present invention, when the motor is rotated and dust is sucked from the suction port, the dust passes through the dust suction port of the bag supporting member of the disposable bag-shaped dust collecting filter and is treated with the disinfectant chemical. Is collected in the bag member subjected to. [0010] When the bag member is full of collected dust, an indicator is activated to notify the user of a decrease in air volume. Thus, the user turns off the power, pulls out the dust collection filter set in the dust collection device from the dust collection device, discards it, and sets a new dust collection filter in the dust collection device. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to one embodiment of FIGS. 1 to 5. FIG. 1 shows the overall internal structure of a vacuum cleaner incorporating a disposable filter 10 according to the present invention. FIG. 2 is a perspective view of a state where the front lid device indicated by reference numeral 6 is opened in FIG. 1 and the bag-shaped dust collecting filter 10 is taken out. FIG. 3 is a perspective view of the dust collection device indicated by reference numeral 4 in FIG. Figure,
FIG. 4 is an enlarged front view of the dust filter 10, and FIG. 5 is a perspective view of FIG. 1 and 2, reference numeral 1 denotes a main body case of a vacuum cleaner, 2 denotes a motor, 3 denotes a cord reel, 4 denotes a dust collecting device, 5 denotes a dust removing device, and 6 denotes a front lid device. The main body case 1 has a handle 7 at an upper part thereof, a caster 8 and wheels 9 at a lower part thereof, and a clogging of a dust collecting filter 10 described later is displayed at an upper front part. 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 room 13, and has a front vibration isolating rubber 14 and a rear vibration isolating rubber 1.
5, 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 (note that the sub-dust collecting filter 18 can be held in time when the dust collecting filter 10 is held, that is, when there is no spare part). The dust bag is incorporated in the dust collecting device 4 in the same manner as in the related art), the paper bag 10a of the dust collecting filter 10, the paper bag supporting member 10b, and the dust discharge integrally provided with the paper bag supporting member 10b. Prevention cover 10c (FIGS. 2 to 5), a paper bag support member support 19 for supporting the paper bag support member 10b, a paper bag support member positioning pin 20 for positioning the paper bag support member 10b in the dust collector 4, and a filter packing. 21 and a net filter 22. The paper bag supporting member 10 b has a dust suction port 23 (FIG. 3), and the dust suction port 23 is connected to a hose port 24 of the front lid device 6 via a seal packing 25. You. Further, a well-known dust removing device 5 is provided at a rear portion of the dust collecting device 4, and the dust collecting device 44 removes dust by the dust removing device 5. In the above configuration, when the motor 2 is rotated and dust is sucked from a suction port (not shown), the dust passes through an extension pipe (not shown) and a hose (not shown), and then passes through the front lid device. 6 through the dust inlet 23 of the paper bag support member 10b from the hose port 24, and is collected in the paper bag 10a. When the paper bag 10a becomes full with the collected garbage, 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 cover device 6 to open the front cover device 6 as shown in FIG. 2, and removes dust from the dust collection filter 10 set in the dust collection device 4.

Thus, in the present embodiment, the paper bag 10a from which dust is collected is a member impregnated with the extermination agent, and the paper bag support member 10b is also impregnated with the insect repellent and the mite insecticide. As a result, the frequency of contact between the harmful microorganisms such as mites and the like and the extermination agent walking around the paper bag 10a increases, and the paper bag supporting member 10
Since the frequency of contact between the pesticide and the harmful microorganisms also increases in part b, the harmful microorganisms that come into contact with the pesticide enter the body through pores and the like, and the paper bag 10
In addition to greatly suppressing the propagation of harmful microorganisms in a, even if there are harmful microorganisms such as mites that escape from the dust filter, they can be killed in a short time. Although the disinfectant does not affect the human body, the user does not want to touch the disinfectant, taking into account the direction in which the user does not want to touch it. If the extermination agent is not applied to the portion, the usability of this type of filter 10 is improved as compared with the case where the extermination agent is applied to the portion of the paper bag support member 10b. If the member 10b is not subjected to the treatment with a pesticide such as microorganisms, it is possible to prevent the user from directly touching the pesticide. Furthermore, if the disinfectant is not applied to the paper bag support member 10b, the amount of the disinfectant can be reduced accordingly, which is economical and contributes to the cost reduction. . Since harmful microorganisms such as mites frequently come into contact with the extermination agent while walking in the paper bag 10a, even if the extermination agent is not applied to the paper bag support member 10b, it can be evaluated as a product. There is no unbearable impact. FIG. 6 is a vertical sectional view showing the vicinity of a dust inlet 23 showing a second embodiment of the filter of the present invention. Among the paper bag supporting members 10b, 10b 'is a paper bag supporting member which is impervious to insect repellents and mite insecticides. , 10b "is a paper bag support member impregnated with 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 laminated in two layers, The paper bag 10a is joined to the inside of the paper bag support member 10b "impregnated with the mite insecticide. In other words, even though the above configuration does not affect the human body, some users do not want to touch it. In consideration of the above, the paper bag supporting member 1 that is directly touched when the dust filter 10 is replaced
Care was taken not to allow the insect repellent and tick insecticide to penetrate the 0b 'portion. FIG. 7 is a vertical sectional side view showing the vicinity of the dust suction port 23 showing a 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 in which a mixed adhesive 26 of insect repellent and tick insecticide is applied to the joint surface. In this embodiment, as in the embodiment shown in FIG. 6, care is taken not to apply insect repellent and tick insecticide to the surface of the paper bag supporting member 10b which is directly touched when the dust collecting filter 10 is replaced. According to the present embodiment, the number of paper bag support members needs to be one less than that of the embodiment of FIG. 6, which contributes to a reduction in cost. FIG. 9 is a front view showing a fourth embodiment of the filter of the present invention, and a, b, and c in FIG. 10 are dust suction ports for sequentially explaining the use state of the dust collecting filter 10 shown in FIG. It is a perspective view near 23, 10b is a paper bag support member of the dust filter 10,
Reference numeral 10c denotes a dust discharge prevention cover integrally connected to the paper bag support member 10b. The paper bag support member 10b and the dust discharge prevention cover 10c are coated or impregnated with insect repellents and mite insecticides. Reference numeral 27 denotes a dust discharge prevention cover 10c (in other words, the dust suction opening 23 provided in the paper bag support member 10b when the dust discharge prevention cover 10c is bent at the boundary with the paper bag support member 10b at the time of discarding the dust. Reference numeral 28 denotes a protective sheet that covers one surface (the surface on which the adhesive 27 is applied) of the dust discharge prevention cover 10c. That is, in the present embodiment, the adhesive 2 applied to the dust discharge prevention lid 10c is used.
7 is covered with a releasable protection sheet 28, the protection sheet 28 is peeled off when the dust is removed, and the dust removal prevention cover 10c is bent, and the dust removal prevention cover 10c is joined to the paper bag support member 10b with an adhesive 27. By doing so, the paper bag supporting member 10
The dust suction port 23 of FIG. 2b is sealed, and the effect is that the inside of the paper bag 10a is sealed so that the mites once collected in the paper bag 10a escape to the outside of the paper bag 10a. Can be reliably prevented. However, as in the first embodiment, also in the second to fourth embodiments, if the insect repellent and the mite insecticide are infiltrated into the paper bag 10a, the mites that walk in the paper bag 10a can be removed. Since the frequency of contact with the insect repellent and the tick insecticide increases, the propagation of mites in the paper bag 10a can be significantly suppressed. For reference, 50 g of powdered feed prepared to a water content of 15% and a test mite 0.5
g in a paper bag, mixed well and stored in a thermostat at a humidity of 80 to 100% for each paper bag (the paper bag was treated with insect repellent and tick insecticide generally marketed in Japan). Ten days later, the paper bag was taken out, 0.1 g of the test mite was taken from the inside of the paper bag, and the number of living mites was counted under a microscope three times. The average results are shown in FIGS. 11 and 12. According to the experiment, as shown in FIG. 11, when the content of the insect repellent and the tick insecticide in the paper bag is 1.23 / m ² or more,
It was confirmed that particularly good mite insecticidal rates were obtained. FIG. 12 (characteristic diagram of months after opening the paper bag-mite insecticidal rate) shows the case of the content of the insecticide paper bag (1.23 / m ² ) based on the above results. In summary, according to the above-described embodiment, the following effects can be obtained. That is, (1) The harmful microorganisms such as house mites and Pteronyssinus mites once collected in the bag-shaped dust collecting filter 10 by the operation of the vacuum cleaner are greatly suppressed from growing in the dust collecting filter 10. Even if mites escape from the dust collecting filter 10, they can be killed in a short time, and recontamination with living environment microorganisms can be prevented. (2) As a result of the above (1), even if the dust collection filter 10 containing the garbage is left in the garbage can for a long time, the filter 10 maintains the sterilizing effect, and the mites in the paper bag 10a are removed from the garbage can. There is no breeding in the inside. (3) As shown in FIGS. 3 to 5, a bendable dust discharge prevention lid 10c, which is integrated with the paper bag support member 10b and closes the dust suction port 23 of the paper bag support member 10b when dumping dust, is provided. By arranging the dust continuously, dust can be prevented from accidentally spilling from the dust suction port 23 when the dust is discarded. (4) As shown in FIG. 6, a paper bag supporting member 1 that does not receive insect repellent and tick insecticide
Ob 'and the paper bag supporting member 10b "provided with the insect repellent and tick insecticide are bonded in two layers, and the paper bag 10a is joined to the inside of the paper bag supporting member 10b" provided with the insect repellent and the tick insecticide, thereby collecting dust. Care was taken not to apply the insect repellent and the mite insecticide to the portion of the paper bag supporting member 10b 'that the hand directly touches when replacing the filter 10. That is, in consideration of the direction that some users do not want to touch even if it has no influence on the human body, the parts of the paper bag supporting member 10b 'that can be directly touched when the dust collecting filter 10 is replaced are replaced with insect repellents and mites. Care was taken not to apply the agent. (5) As shown in FIG. 7 and FIG. 8, the insect repellent and the tick insecticide are applied to the paper bag support member 10b on the paper bag mounting side, which is the back surface, as in the embodiment of FIG. In addition, care can be taken not to apply insect repellent and tick insecticide to the surface of the paper bag supporting member 10b which is directly touched when the dust collecting filter 10 is replaced, and according to the embodiment of FIGS. The number of paper bag support members is one less than that of the embodiment, which contributes to a reduction in cost. (6) As shown in FIGS. 9 and 10, a dust discharge prevention lid 10 c is provided integrally with the paper bag support member 10 b and faces the dust suction port 23 of the paper bag support member 10 b when dumping dust. An adhesive 27 is applied to the surface, and the surface of the adhesive 27 is covered with a releasable protection sheet 28, so that when the dust is discarded, the dust discharge prevention cover 1 is removed.
The protective sheet 28 can be peeled off when the paper bag 0c is folded, and the dust discharge prevention lid 10c can be joined to the paper bag support member 10b with an adhesive 27 to seal the dust suction port 23 of the paper bag support member 10b. By sealing the inside of the paper bag 10a, it is possible to reliably prevent the mites once collected in the paper bag 10a from getting out of the paper bag 10a. It is not a dust filter for a vacuum cleaner itself, but a “method of sterilizing exhaust gas”.
Japanese Patent Laid-Open Publication No. Sho 50-128677 discloses a technique of applying a germicide around an air passage in a vacuum cleaner main body. However, the problem to be solved by the technology described in the publication is to remove various bacteria in the airflow discharged from the cleaner body. However, according to the technique described in Japanese Patent Application Laid-Open No. 50-128677,
It is fully conceivable that the disinfectant applied around the air passage in the cleaner body may come off and come into contact with dust, particularly hard dust, sucked into the cleaner body at high speed, and this is repeated for a long time. Therefore, it is unavoidable that the sterilizing agent, that is, the sterilizing agent applied to the vicinity of the air passage in the cleaner main body also impairs the effect of removing various bacteria in the exhaust stream. On the other hand, when the disinfectant applied around the air passage in the cleaner body is peeled off,
Alternatively, it is conceivable to re-apply the disinfectant around the air passage periodically, but it is difficult for a general user to apply the disinfectant to a narrow space, such as the air passage in the cleaner body. On the other hand, entrusting this work to a contractor each time is cumbersome, troublesome, and hardly a practical method. On the other hand, when an electric vacuum cleaner treated by the insecticidal method described in the above-mentioned Japanese Patent Application Laid-Open No. 50-128677 is used, there are the following problems. That is, even when the vacuum cleaner described in Japanese Patent Application Laid-Open No. 50-128677 is used, if the dust collecting portion is full of dust, the dust is removed from the cleaner body. Although the garbage discarded as described above does not have a barrier object (eg, a bag wall of a paper bag) around the garbage, pests such as ticks that have survived in the garbage can easily be surrounded. There is a problem of crawling out. In other words, in the prior art disclosed in Japanese Patent Application Laid-Open No. 50-128677, the garbage filled in the cleaner body is taken out from the cleaner body, and is used as an environmental countermeasure against pests after being discarded. They are not aware of hygiene protection and there is room for improvement in this regard. On the other hand, according to the present invention, propagation of harmful microorganisms such as house mites and Acarina mites once collected in the bag-shaped dust filter by the operation of the vacuum cleaner is greatly suppressed, Furthermore, even if mites escape from the dust collecting filter, they can be killed in a short time, and recontamination by living environment microorganisms can be prevented. In the above-mentioned embodiment, the case where the insect repellent and the mite insecticide are used is exemplified. However, a microbial insecticide having the same effect as this can be used. According to the present invention, even after the dust collection filter has been used up after the dust collection , it can be treated with a microorganism-controlling agent.
Harmful microorganisms are trapped in the bag member with
In the dust collection filter, the harmful microorganisms are effectively controlled,
Can be prevented . The ease of handling of conventional disposable dust collection filters and the
A relatively regular garbage disposal cycle in daily cleaning habits
By replacing the filter with a new dust filter, the effectiveness of the microbial
The medicinal effect lasts.
