[0015]
FIG. 2 shows an external view of a vacuum cleaner according to this embodiment. In FIG. 2, 1 is a vacuum cleaner body, 2 is a hose body, 6 is a handle grip, 3 is a hand switch, 4 is an extension tube, and 5 is a mouthpiece body. An electric blower that generates a suction force and a dust collection chamber on the suction side of the electric blower are provided inside the main body casing that forms the outline of the main body of the vacuum cleaner.
[0016]
Although not shown in the figure, the hose body 2 and the extension pipe 4 are provided with a power supply line for supplying to the motor 105 of the suction body, and the first connection pipe 102 and the second connection pipe 103 are provided with extensions. When the tube 4 is connected, a lead wire connected to the circuit board 106 is provided. Further, the circuit board 106 and the electric motor 105 are connected by a lead wire disposed in the lower suction case 101.
[0017]
FIG. 3 is a cross-sectional view taken along the line AA of the mouthpiece according to this embodiment. In FIG. 3, 301 is a suction case upper case, 302 to 305 are cleaning members for a rotary cleaning body, 306 is a cylindrical base for fixing the cleaning members 302 to 305, and 307 is a rotary cleaning body chamber.
[0018]
A suction body upper case 301 is provided on the upper side of the suction body lower case 101 so as to be detachable from the suction body lower case 101 so as to cover the rotary cleaning body 104, and the suction body upper case and the suction body lower case 101. And constitutes a rotary cleaning body chamber 307 in which the rotary cleaning body 104 is accommodated. In addition, an opening 118 for sucking dust on the surface to be cleaned is formed on a surface of the lower suction body 101 facing the surface to be cleaned, which allows the rotary cleaning body 104 and the surface to be cleaned to contact. Yes.
[0019]
The cleaning members 302 to 305 of the rotary cleaning body 104 can be configured using soft blades in addition to brushes made of fibers or the like. The brushes and blades can be used alone or in combination with brushes and blades. Can be configured. Further, the cleaning member may be constituted by a protrusion formed integrally with the member forming the cylindrical base 306. In any case, the cleaning member is configured to protrude outward from the outer peripheral surface of the cylindrical base body 306.
[0020]
The cleaning members 302 to 305 are mixed with or coated with an antibacterial agent having an antibacterial action (a function of preventing or suppressing the growth of microorganisms such as bacteria and sputum). The antibacterial agent may be silver ions, copper ions, or zinc ions that are generally pollution-free and are used in water purifiers for beverages. In this embodiment, the nylon brush is acrylic-coated with zeolite (Sinenen: Zeomic) containing silver ions.
[0021]
Next, the operation of this embodiment will be described. When the vacuum cleaner user operates the switch operation unit 3 disposed in the vicinity of the handle grip 6, the electric blower in the vacuum cleaner body 1 operates in an operation mode according to the operated switch. The suction force generated by the electric blower reaches the suction body 5 through the hose body 2 and the extension pipe 4. At the same time, the power supplied from the power supply lines provided in the hose body 2 and the extension pipe 4 drives the electric motor 105 through the circuit board 106, and the rotary cleaning body 104 rotates.
[0022]
The contact member 108 (109) is installed so as to come into contact with the cleaning members 302 to 305 of the rotary cleaning body 104.
[0023]
When the mouthpiece 5 is moved on the surface to be cleaned as shown in FIG. 4, the air containing dust from between the mouthpiece lower case 101 and the surface to be cleaned enters the rotary cleaning body chamber 307 from the floor surface opening 118. Inflow, dust is scraped out by the rotary cleaning body 104 and sucked into the main body of the vacuum cleaner through the extension pipe and the hose.
[0024]
At this time, in homes where animals are kept, bacteria often adhere to the surface to be cleaned due to mite carcasses or dust containing moisture in addition to dust, and breed. In addition, when a person with ringworm bacteria walks with bare feet, the bacteria may be scattered or attached.
[0025]
In such a case, in the present embodiment, it is possible to wipe off the attached fungi 11 at the same time as the dust is scraped by the rotational force of the cleaning members 302 to 305 of the rotary cleaning body 104.
[0026]
The fungus thus scraped off adheres to the cleaning members 302 to 305 of the rotary cleaning body 104 or adheres to the inner surface of the mouthpiece 5, and the rest are conveyed to the cleaner body. In the present embodiment, the antibacterial treatment is performed on the cleaning members 302 to 305 of the rotary cleaning body 104, so that not only dust is scraped but also the growth of bacteria attached to the cleaning members 302 to 305 can be suppressed.
[0027]
Therefore, it is possible to sanitize the rotary cleaning body in which dust and bacteria are most likely to accumulate.
[0028]
Furthermore, since the fungus 11 adhering to the surface to be cleaned is peeled off by the rotational force of the cleaning body, the propagation of bacteria on the surface to be cleaned can be suppressed.
[0029]
The antibacterial agent (zeomic) used for the cleaning members 302 to 305 is stable because silver ions or the like showing antibacterial properties are bonded to the inside of the skeleton structure. Therefore, it is hardly eluted by an aqueous solvent and the antibacterial action lasts for a long time. It can also be washed with water.
[0030]
The zeomic content in the nylon brush is about 0.005 g per one, and 0.015% of about 1% of zeomic is a silver ion component.
[0031]
In addition, in order to confirm antibacterial property, the test was done by the method according to JISZ2801 (film adhesion method). As a result, as shown in FIG. 5, in the conventional brush without antibacterial, Staphylococcus aureus hardly decreased after 24 hours, whereas in the brush with antibacterial of this embodiment, S. aureus 24 After time, the number of cocci decreased by 4 orders of magnitude, demonstrating antibacterial effects.
[0032]
As described above, since an antibacterial effect can be obtained by mixing a small amount of silver ion component into the cleaning member, the cost does not increase significantly.
[0033]
Moreover, since the basic physical properties of nylon, which is a cleaning member, are not changed, there is no worry about wear due to mechanical force.
[0034]
When storing the vacuum cleaner, place the rear of the cleaning body vertically in the lower part (installation surface), and fit the suction body into the recess near the upper part of the body with a hook installed on the extension pipe. Placed side by side.
[0035]
Since the suction body 5 is stored with the suction floor surface facing the floor or the like, the cleaning members 302 to 305 of the rotary cleaning body 104 are placed in contact with the floor. Accordingly, antibacterial activity on the floor where the mouthpiece is in contact is possible even when stored.
[0036]
At this time, the antibacterial agent is also mixed into the fixed brush and the front and rear wheels of the mouthpiece 5, so that the floor surface can be made more antibacterial and hygienic.
[0037]
Further, in this embodiment, the cleaning members 302 to 305 rub against the contact member 108 (109) by the rotation of the rotary cleaning body 104 to generate static electricity, so that the cleaning members 302 to 305 become the positive electrode and the contact member 108 ( 109) is charged to the negative electrode.
[0038]
The negative charge generated in the contact member 108 reaches the conductive fiber 110 through the upper case 301 and the lower case 101. Corona discharge is generated between the negative charge of the conductive fiber 110 and the rubbing members 302 to 305 of the rotary cleaning body 104 charged to the positive electrode.
[0039]
The negative charge discharged by this corona discharge ionizes oxygen in the air and ionizes it, generating negative ions.
[0040]
In general, it is known that dust on the surface to be cleaned is often charged on the positive electrode. However, when cleaning is performed by moving the suction body back and forth, the generated negative ions are transferred to the rotary cleaning body chamber 307. The dust on the surface to be cleaned is electrically neutralized with the dust discharged from the under floor opening, thereby facilitating the separation of the dust from the surface to be cleaned.
[0041]
The separated dust is carried by the suction force generated by the electric blower in the vacuum cleaner body 1 and is sucked into the cleaner body 1 through the tubular air passage formed in the extension pipe 4 and the hose 2. .
[0042]
Further, the surface charge of bacteria is often charged on the positive electrode, and can be scraped off more effectively by the generation of negative ions.
[0043]

The suction body upper case 402 and the suction body lower case 401 forms a rotary cleaning body chamber 307 in which the rotary cleaning body 104 is accommodated. In addition, an opening 118 for sucking dust on the surface to be cleaned is formed on a surface of the lower suction body 101 facing the surface to be cleaned, which allows the rotary cleaning body 104 and the surface to be cleaned to contact. Yes.
[0046]
The cleaning members 302 to 305 of the rotary cleaning body 104 have the same configuration as [Embodiment 1], and an antibacterial agent having an antibacterial action is mixed or applied.
[0047]
Further, the mouthpiece upper case 402 and the mouthpiece lower case 401 are mixed or coated with an antibacterial agent having an antibacterial action. In the present embodiment, the mouthpiece upper case 402 and the mouthpiece lower case 401 are made of acrylonitrile / butadiene / styrene resin (ABS) and kneaded with a zinc-based inorganic antibacterial agent.
[0048]
Next, the operation of this embodiment will be described. When the vacuum cleaner user operates the switch operation unit 3 disposed in the vicinity of the handle grip 6, the electric blower in the vacuum cleaner body 1 operates in an operation mode according to the operated switch. The suction force generated by the electric blower reaches the suction body 5 through the hose body 2 and the extension pipe 4. At the same time, the power supplied from the power supply lines provided in the hose body 2 and the extension pipe 4 drives the electric motor 105 through the circuit board 106, and the rotary cleaning body 104 rotates.
[0049]
When the suction body 400 is moved on the surface to be cleaned, air containing dust flows between the suction body lower case 401 and the surface to be cleaned from the floor surface opening 118 into the rotary cleaning body chamber 307, and the rotary cleaning body. The fungi 11 are scraped together with dust by the rotational force 104 and sucked into the main body of the vacuum cleaner via the extension pipe and the hose.
[0050]
The scraped fungus 11 adheres to the cleaning members 302 to 305 of the rotary cleaning body 104 or adheres to the inner surface of the suction body 400, and the rest are conveyed to the cleaner body. In this embodiment, since the cleaning members 302 to 305 of the rotary cleaning body 104, the suction body lower case 401, and the suction body upper case 402 are subjected to antibacterial treatment, not only the dust is scratched but also the cleaning members 302 to 305 At the same time as suppressing the growth of attached bacteria, it is possible to suppress the growth of bacteria adhering to the mouthpiece lower case 401 and the mouthpiece upper case 402.
[0051]
Therefore, the inside of the mouthpiece 400 can be made completely antibacterial.
[0052]
In this embodiment, different antibacterial agents are applied to the mouthpiece lower case 401 and the mouthpiece upper case 402 constituting the rotary cleaning body and the mouthpiece, respectively, so that they exhibit antibacterial effects on a wide variety of fungi. I can do it.
[0053]
[Example 3]
Hereinafter, a third embodiment of the present invention will be described in detail with reference to the drawings. FIG. 7 is a perspective view of the cleaner body. FIG. 8 is a perspective view showing a state in which the upper cover of the cleaner body is opened. FIG. 9 is a schematic view showing the flow of air in the cleaner body.
[0054]
The vacuum cleaner body 1 incorporates an electric blower (described later), and sucks dust into the intake flow by sucking in from the suction port 5 by the suction force of the electric blower. The vacuum cleaner main body 1 is sucked through the hand operating section 3 and the hose 2, dust is removed (collected) by a cyclone separation type dust collecting section (described later), and then exhausted outside the apparatus.
[0055]
As shown in FIGS. 7 to 9, the vacuum cleaner main body 1 has a cyclone separation cylinder 204 and a dust collection case 205 detachably mounted between the lower case 201 and the upper lid 202, and between the lower case 201 and the upper case 250. The second auxiliary filter 212, the electric blower 207, and a cord reel (not shown) are incorporated in the interior. These are collectively referred to as a dust collection chamber 203.
[0056]
As shown in FIG. 9, the cleaner body 1 separates dust by centrifugal action by pouring dust-containing air from the inlet pipe 215 into the cyclone separation cylinder 204 through the hose 2 and swirling. Dust is conveyed to the dust collecting case 205 through the upper communication port 217, and the exhaust from the cyclone separation cylinder 204 is exhausted through the inner cylinder 231 to the exhaust port 220 provided at the lower part of the cyclone separation cylinder 204. Part of the air flows into the dust collection case 205 and is captured by the first auxiliary filter 206. The exhaust from the dust collecting case 205 is sucked into the electric blower 207 through the second auxiliary filter 212 from the cyclone outlet 146 behind the first auxiliary filter 206. At this time, the exhaust from the cyclone separation cylinder 204 also passes through the communication passage 245 from the exhaust port 220, flows out from the cyclone outlet 246, and is sucked into the electric blower 207 together with the exhaust from the dust collecting case 205. Exhaust from the electric blower 207 passes through a filter 208, partly through an exhaust passage (not shown), partly flows through a cord reel, cools them, and then discharges outside the apparatus.
[0057]
The dust collecting case 205 can be taken out by holding the handle 223 at the top of the dust collecting case 205, and the dust in the dust collecting case 205 is discarded by opening the first auxiliary filter 206 in the dust collecting case 205. .

Further, when the inside of the cyclone separation cylinder 204 becomes dirty, the upper handle 225 can be held and lifted from the lower case 201, and the cyclone separation cylinder 204 can be disassembled and cleaned.
[0059]
Here, the inner surface of the cyclone separation cylinder 204 or the inner surface of the dust collecting case 205 is subjected to a clear UV curable coating treatment. For this reason, when dust flows into the cyclone separation cylinder 204, the dust is centrifuged and flows into the dust collection case 205, the dust is deposited on the surface of the cyclone separation cylinder 204 and the inner surface of the dust collection case 205. In the case of collision and rubbing, it is difficult for scratches to be made on the surface, making it difficult for dirt to adhere, and improving abrasion resistance and contamination resistance. For this reason, even when the outer cylinder 235 of the cyclone separation cylinder 204 and the dust collection case 205 are made of a transparent plastic material, the degree of dust accumulation can be visually confirmed.
[0060]
Here, the cyclone separation cylinder 204 and the dust collecting case 205 are made of acrylonitrile / butadiene / styrene resin (ABS), and are kneaded with a zinc-based inorganic antibacterial agent.
[0061]
The first auxiliary filter 206 is made of polypropylene resin (PP), kneaded with a metal oxide inorganic antibacterial agent, and the second auxiliary filter 212 is made of a cellulose-based non-woven fabric, and the enzyme component is subjected to fiber surface treatment. is doing.
[0062]
As a result, all the places where dust and bacteria come into contact are wrapped with an antibacterial material, so that an antibacterial dust collection chamber can be achieved.
[0063]
Next, the operation of this embodiment will be described. When the vacuum cleaner user operates the switch operation unit 3 disposed in the vicinity of the handle grip 6, the electric blower in the vacuum cleaner body 1 operates in an operation mode according to the operated switch. The suction force generated by the electric blower reaches the suction body 5 through the hose body 2 and the extension pipe 4. At the same time, the power supplied from the power supply lines provided in the hose body 2 and the extension pipe 4 drives the electric motor 105 through the circuit board 106, and the rotary cleaning body 104 rotates.
[0064]
When the suction body 400 is moved on the surface to be cleaned, air containing dust flows between the suction body lower case 401 and the surface to be cleaned from the floor surface opening 118 into the rotary cleaning body chamber 307, and the rotary cleaning body. The fungi 11 are scraped together with dust by the rotational force 104 and sucked into the main body of the vacuum cleaner via the extension pipe and the hose.
[0065]
The scraped fungus 11 adheres to the cleaning members 302 to 305 of the rotary cleaning body 104 and the inner surface of the suction body 400, but the rest are conveyed to the cleaner body.
[0066]
The fungus that has passed through the mouthpiece may grow with the dust, so it is desirable that the fungus be antibacterial at the dust collection part of the cleaner body.
[0067]
In this embodiment, the cleaning members 302 to 305 of the rotary cleaning body 104, the suction body lower case 401, the suction body upper case 402, the cyclone separation cylinder 204 and the dust collection case 205 constituting the dust collection portion 203, and the first auxiliary Since the filter 206 and the second auxiliary filter 212 are subjected to antibacterial treatment, not only the dust is scraped out, but also the growth of bacteria adhering to the cleaning members 302 to 305 is suppressed, and at the same time, the lower mouthpiece case 401 and the mouthpiece The propagation of bacteria attached to the upper case 402 can be suppressed. Furthermore, the growth of bacteria attached to the inner surface of the dust collection unit 203 can be suppressed.
[0068]
As described above, since all the parts that are touched by the suction body, the rotary cleaning body, and the dust collecting portion are wrapped with the antibacterial material, a fully antibacterial vacuum cleaner can be provided.
[0069]
【The invention's effect】
