  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a schematic view showing the configuration of a canister-type vacuum cleaner according to the first embodiment of the present invention. FIG. 2 shows a front view of the vacuum cleaner dust bag in the same embodiment.

  In FIG. 1, a vacuum cleaner 1 includes a vacuum cleaner body 6 having a dust collection chamber 3 communicating with a main body intake port 2 and a blower chamber 5 provided with an exhaust port 4, and a main body intake port 2 and an airtightness in the dust collection chamber 3. A vacuum cleaner dust bag 7a, a suction fan motor 8 installed in the blower chamber 5, a hose 9 airtightly connected to the main body inlet 2, and a power on / off of the vacuum cleaner 1 And gripping part 11 having various switches 10 for operating settings such as suction force, floor nozzle 12 for sucking dust from the surface to be cleaned, and floor nozzle 12 and gripping part 11 for airtight connection Connecting pipe 13.

The vacuum cleaner dust collection bag 7a includes a breathable storage bag 15 filled with a powdered deodorant 14, a breathable filtration bag 16 for filtering and collecting sucked dust, and a cleaning bag. A wick 18 having an opening 17 for machine mounting is provided, and a part of the storage bag 15 is installed in a state of protruding from the opening 17 of the wick 18. For the storage bag 15, one nonwoven fabric having a basis weight of 30 g / m ² and a thickness of 0.2 mm was used, formed into a bag shape, and filled with a powdery deodorant 14 inside. Further, as the powdery deodorant 14, zeolite, activated carbon, transition metal catalyst or the like having an odor adsorbing action can be used. In this embodiment, zeolite powder having a particle size of 10 μm or less was used.

  About the vacuum cleaner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, when the suction fan motor 8 is driven, the inside of the dust collecting chamber 3 is brought into a negative pressure state, and the floor nozzle 12 sucks the air flow A containing dust from the surface to be cleaned, and the connecting pipe 13, the gripping part 11, and the hose. 9 passes through the air passage in 9 and flows into the main body inlet 2. The air flow B including dust flowing into the main body inlet 2 passes through the opening 17 of the wick 18 of the vacuum cleaner dust bag 7 a mounted in the dust chamber 3 and flows into the filter bag 16. To do. Dust contained in the air flow A is filtered by the filter bag 16 and collected in the filter bag 16. A part of the air flow B flowing in from the opening of the wick 18 collides with the storage bag 15 protruding from the opening 17 and flows into the storage bag 15. The flowing air stream B pushes out the powdery deodorant filled in the storage bag 15 from the vent of the storage bag 15 and puts it into the filter bag 16. The deodorizing agent 19 put in the filter bag 16 in this way uniformly adheres to the surface or inside of the dust collected by filtration, and the odor generated from the dust is efficiently generated at the odor generating source near the dust. Deodorize. The air flow D from which the odor has been removed passes through the filter bag 16 and is sucked into the suction fan motor 8. The air flow E that has passed through the suction fan motor 8 is discharged from the exhaust port 4 of the blower chamber 5.

  As described above, in the present embodiment, dust collected in the filter bag 16 is generated by mounting the vacuum cleaner dust collection bag 7 a of the present invention in the dust collection chamber 3 of the vacuum cleaner 1. The odor is continuously deodorized by the deodorant adhering to the dust, so that the exhaust from the cleaner body 6 is greatly reduced in odor, and the odor is long-term regardless of the amount of dust in the filter bag 16. It is possible to provide the vacuum cleaner 1 with less exhaust odor that maintains the performance of deodorizing the odor of dust.

(Experimental example 1)
Using the electric vacuum cleaner 1 described above, an exhaust odor comparison experiment was performed. In the comparative experiment, using the vacuum cleaner 1 and a vacuum cleaner equipped with a vacuum cleaner dust bag without a deodorant, the actual room was cleaned for 15 minutes a day for 2 months each. I went every day.

  As a result of continuing cleaning with sensual awareness of exhaust odor, in vacuum cleaners not equipped with a deodorizer, a dusty odor began to be recognized in the exhaust immediately after the start of operation about 3 days after the start of the experiment. . Thereafter, the intensity of exhaust odor increased over time, and a strong dust odor was always recognized during cleaning after 2 months. On the other hand, in the vacuum cleaner 1 of the present embodiment, the exhaust odor was not bothered at the start of cleaning and during the cleaning from the start of the experiment to the end of the experiment. The amount of dust collected in the filter bag 16 of the vacuum cleaner 1 of the present embodiment and the vacuum cleaner not equipped with a deodorizing agent is almost the same amount after two months, and about 350 g of dust is collected. It was.

Next, each vacuum cleaner after two months passed was set in a 1 m ³ sealed chamber and operated for 60 seconds. The air in the chamber was smelled and sensory evaluated by six sensory panelists of mixed gender, and a 6-step odor intensity of 0 to 5 was determined. As a result, in the vacuum cleaner 1 of the present embodiment, the average odor intensity was 1.2, whereas in the vacuum cleaner not provided with the deodorizer, the average odor intensity was 3.6, It was confirmed quantitatively that the vacuum cleaner 1 of this embodiment has a higher deodorizing effect. Moreover, as a result of disassembling the vacuum cleaner dust bag attached to the vacuum cleaner of the present embodiment after the end of the experiment, it was observed that the deodorizer adhered to the entire dust almost uniformly.

  From the above results, the vacuum cleaner 1 according to the present embodiment can reduce the odor generated by dust even when a large amount of dust is sucked and held for a long time, and the effect can be maintained for a long time. .

  Here, in the present embodiment, an extremely high odor reduction effect is obtained for the following reason. That is, when the powdery deodorizer 19 becomes an infinite number and adheres to each individual dust, the contact area with the dust becomes extremely large, so that a high deodorizing performance can be obtained, and the dust as a whole This is because the deodorizer is mixed and left in the dust and remains as it is, and the deodorant in the state of being retained continues to deodorize the odor of the dust. In other words, in the present invention, the particle size of the powdered deodorant is set in advance so as to be larger than the ventilation diameter of the filter bag 16, and does not flow out of the filter bag 16 even if dust is sucked by the suction fan motor 8. It is important that they remain in the filter bag 16.

  Moreover, it is necessary to select the ventilation diameter of the storage bag 15 according to the particle size of the deodorizer set for the above reason and the usage environment of the vacuum cleaner. That is, the powdery deodorant 14 receives kinetic energy from the air flow generated during the operation of the vacuum cleaner and is pushed out from the vent hole of the storage bag 15. At this time, the deodorizer 14 is passed by van der Waals force or electrostatic attraction. In order to clog and clog the pores, the net air diameter is smaller than the air diameter of the material of the storage bag 15, and the input amount of the deodorant 19 varies depending on the air flow velocity and the operation time of the vacuum cleaner. To do. In other words, in the present invention, the air diameter of the material used for the storage bag 15 is larger than the particle size of the powdered deodorant, and a sufficient amount of the deodorant can be input with respect to the operating flow rate range and operation time of the cleaner. It is very important to set it so that The above points are the same in the embodiments described below.

  In this embodiment, the case where the storage bag 15 is installed in the filter bag 16 has been described. However, as shown in FIG. 3, a closed space is formed between the filter bag 16 and the wick 18 having the opening 17. The communication case 20 is formed, and the communication case 20 is provided with an opening 21 that communicates with the opening 17, and the storage bag 15 is disposed in the communication case 20 with a part thereof protruding into the opening 17. The vacuum cleaner dust bag 7b configured as described above provides the same deodorizing effect and does not require any special processing in the filter bag 16, so that the folded filter bag 16 is connected to the communication case 20 in the manufacturing process. It becomes possible to manufacture the dust-collecting bag 7b for a vacuum cleaner by finally bonding to, and the manufacturing process can be simplified.

(Embodiment 2)
FIG. 4: shows the front view of the dust-collecting bag for vacuum cleaners in the 2nd Embodiment of this invention. In the first embodiment of the present invention, the storage bag has a tapered shape in which the plane cross-sectional area continuously decreases toward the opening of the wick, and one woven fabric is used as a material having air permeability. Other than the above, the components have the same configuration, and the same components are denoted by the same reference numerals and detailed description thereof is omitted. For the storage bag, a woven fabric having a texture of 1 mm in length and 2 mm in width was used, formed into a bag shape, and filled with a powdery deodorant inside.

  The operation and action of the vacuum cleaner dust bag configured as described above will be described below.

  First, the air flow B containing dust flows into the opening 17 of the wick 18, and the dust contained in the air flow B is filtered by the filter bag 16 and collected in the filter bag 16. A part of the air flow flowing in from the opening 17 of the wick 18 collides with the storage bag 15 protruding from the opening 17 and flows into the storage bag 15. The flowing air stream C pushes out the powdery deodorant 14 filled in the storage bag 15 from the texture of the storage bag 15 and puts it into the filter bag 16.

  In the deodorizing agent 19 in the storage bag 15, the deodorizing agent 19 in the region protruding from the opening portion 17 has a space after being put into the filter bag 16 by the air flow C that has flowed in. At that time, the deodorizing agent remaining in the storage bag 15 is gravity settled toward the opening 17 along the taper 22 due to vibration or impact caused by movement of the cleaner body 6 or the like, and accumulates in the generated space. By repeating this operation, the powdery deodorant 14 filled in the storage bag 15 always settles toward the opening 17 side of the storage bag 15. Thus, the deodorizing agent 14 put into the filter bag 16 uniformly adheres to the surface or inside of the dust collected by filtration and efficiently deodorizes at the odor generation source near the dust. While the air flow B flows from the wick 18, the deodorizing agent 19 is continuously put into the filter bag 16 and adheres to dust. The air flow D from which the odor has been removed passes through the filter bag 16 and is discharged out of the filter bag 16.

  As described above, in the present embodiment, by installing the storage bag 15 of woven cloth having a tapered shape whose plane cross-sectional area continuously decreases toward the opening 17 of the wick 18, The powdery deodorant 14 filled in the bag always settles smoothly toward the opening 17 along the taper 22 of the storage bag 15, so that the deodorant 14 does not collect in the corner of the storage bag 15, and finally The deodorant 14 filled in can be charged without waste. In addition, since the texture of the woven fabric is uniform in size compared to the nonwoven fabric, the clogged state by the powdery deodorant 14 is also uniform, and the same amount of deodorizer 14 is introduced from each texture, That is, the deodorizing agent 19 can be introduced stably as a whole.

  In the first embodiment or the second embodiment, the case where a storage bag in which one material having air permeability is formed into a bag shape is used. However, the material is not limited to one, and a plurality of materials having air permeability. The storage bag may be formed into a bag shape by laminating layers, and the strength of the storage bag can be improved compared to the case of a single sheet. By doing so, the air diameter can be controlled to be small, and the input amount of the deodorizing agent 19 can be adjusted.

  Furthermore, by using a dust bag for vacuum cleaners that uses a combustible material that can be processed in an incinerator, the material of the storage bag can be discarded as burnable garbage after the use of the dust bag is finished. , And can be discarded without being separated from the filter bag and the wick by the operator.

  As described above, the vacuum cleaner dust collecting bag according to the present invention can maintain the performance of deodorizing dust for a long time regardless of the amount of dust in the filter bag. It can be applied to applications such as industrial vacuum cleaners and commercial vacuum cleaners.
