Description

　本発明はアジテータを有する掃除機用床ノズルに関するものである。 The present invention relates to a floor nozzle for a vacuum cleaner having an agitator.

　従来の掃除機用床ノズル１（以下単に床ノズル１と称する）について、図５・図６を用いて説明する。２は絨毯面上で回転して塵埃を掻き上げるアジテータで、非導電性の樹脂材料で形成した回転子３とその周面に設けたブレード４で形成している。モータ５は、前記アジテータ２の駆動源となっている。 A conventional vacuum cleaner floor nozzle 1 (hereinafter simply referred to as floor nozzle 1) will be described with reference to FIGS. Reference numeral 2 denotes an agitator that rotates on a carpet surface to scrape dust, and is formed by a rotor 3 formed of a non-conductive resin material and a blade 4 provided on a peripheral surface thereof. The motor 5 is a drive source for the agitator 2.

　図７に示しているように、アジテータ２が回転することによってブレード４が清掃面である絨毯６の表面の塵埃７を掻き上げ、図示していない掃除機本体が発生する吸引力によってこの塵埃を、ケーシング部８を介して床ノズル延長管入口部９から、掃除機本体内に搬送するものである。 As shown in FIG. 7, when the agitator 2 rotates, the blade 4 scrapes up the dust 7 on the surface of the carpet 6, which is the cleaning surface, and removes the dust by the suction force generated by the cleaner body (not shown). It is transported from the floor nozzle extension pipe inlet 9 through the casing 8 into the cleaner body.

　前記従来の構成の床ノズル１は、アジテータ２が絨毯面上で回転すると静電気を生じるという課題を有しているものである。つまりアジテータ２が回転すると、ブレード４と絨毯６の表面とが摩擦し合って、床ノズル１と絨毯６の両方に静電気が生ずるものである。しかも、アジテータ２が掻き上げた塵埃７もケーシング部８と摩擦し合って静電気を生ずるものである。この静電気の発生によって、絨毯６内の塵埃は絨毯面に残留している静電気によって絨毯表面に強く付着し、床ノズル１の集塵性能を低下させるものである。また、床ノズル１外面に塵埃が付着して美観をそこねたり、使用者が床ノズル１に触れると電気ショックを感じるなどの課題を有しているものである。 床 The floor nozzle 1 of the conventional configuration has a problem that when the agitator 2 rotates on the carpet surface, static electricity is generated. That is, when the agitator 2 rotates, the blade 4 and the surface of the carpet 6 rub against each other, and static electricity is generated on both the floor nozzle 1 and the carpet 6. In addition, the dust 7 agitated by the agitator 2 also generates static electricity by friction with the casing portion 8. Due to the generation of the static electricity, the dust in the carpet 6 strongly adheres to the carpet surface due to the static electricity remaining on the carpet surface, thereby lowering the dust collecting performance of the floor nozzle 1. In addition, there is a problem that dust adheres to the outer surface of the floor nozzle 1 to degrade the appearance and that a user touches the floor nozzle 1 to feel an electric shock.

　本発明はこのような従来の構成が有している課題を解決しようとするもので、集塵性能が高い掃除機用床ノズルを提供することを目的としている。 The present invention is intended to solve the problems of such a conventional configuration, and has an object to provide a floor nozzle for a vacuum cleaner having high dust collection performance.

　（実施の形態１）
　以下、本発明の第一の実施の形態を、図１・図２を参照して説明する。アジテータ１３は、回転子１１とその周面に設けているブレード１２で形成している。１４は、アジテータ１３を駆動する駆動源である。アジテータ１３の駆動によって掻き上げられた絨毯面の塵埃は、図示していない掃除機本体が発生する吸引力によって掃除機本体の吸気によってケーシング部１６を介して床ノズル延長管入口部１５まで搬送され、掃除機本体内に集塵される。１７は、ケーシング部１６内に設けている静電気を中和し除去する電極で、高電圧発生回路１８によって高電圧を印荷される。 (Embodiment 1)
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. The agitator 13 is formed by the rotor 11 and the blade 12 provided on the peripheral surface thereof. A drive source 14 drives the agitator 13. The dust on the carpet surface, which is lifted up by the driving of the agitator 13, is conveyed to the floor nozzle extension pipe inlet 15 through the casing 16 by the suction of the cleaner main body by suction force generated by the cleaner main body (not shown). , Is collected in the cleaner body. Reference numeral 17 denotes an electrode provided in the casing portion 16 for neutralizing and removing static electricity, and a high voltage is applied by the high voltage generation circuit 18.

　以下、本実施の形態の動作について説明する。高電圧発生回路１８が電極１７に高電圧を印荷すると、電極１７はイオンを発生する。このイオンは正極性のものと負極性のものとがあり、正極性のものは静電気によって負に帯電している電荷を中和し、正極性のものは同様に正に帯電している電荷を中和するように作用するものである。つまり、アジテータ１３を構成するブレード１２と絨毯表面との摩擦によって絨毯表面とケーシング部１６とが正または負に帯電しても、このイオンによって電荷が中和されるものである。従って、絨毯表面は除電されることになり、絨毯内の塵埃が絨毯表面に静電気によって吸着されるような現象は生じないものである。 Hereinafter, the operation of the present embodiment will be described. When the high voltage generation circuit 18 applies a high voltage to the electrode 17, the electrode 17 generates ions. There are positive ions and negative ions.Positive ions neutralize negatively charged charges by static electricity, and positive ions similarly dissipate positively charged charges. It acts to neutralize. That is, even if the carpet surface and the casing portion 16 are positively or negatively charged due to friction between the blade 12 constituting the agitator 13 and the carpet surface, the charge is neutralized by the ions. Therefore, the surface of the carpet is neutralized, and the phenomenon that dust in the carpet is adsorbed on the carpet surface by static electricity does not occur.

　つまり、本実施の形態の掃除機用床ノズルは、集塵性能の高い掃除機用床ノズルとして作用するものである。またケーシング部１６に帯電することもないため、床ノズル外面に塵埃が付着して美観をそこねたり、使用者が床ノズルに触れて電気ショックを感じるなどの問題点もなくなり安全性が向上するものである。 That is, the floor nozzle for a vacuum cleaner according to the present embodiment functions as a floor nozzle for a vacuum cleaner having high dust collection performance. In addition, since the casing portion 16 is not charged, dust adheres to the outer surface of the floor nozzle to deteriorate the appearance, and there is no problem that the user touches the floor nozzle and feels an electric shock, thereby improving safety. Things.

　（実施の形態２）
　続いて本発明の第二の実施の形態を、図３・図４に基づいて説明する。図４は、本発明の第二の手段の第二の実施の形態を示している。本実施の形態では、ケーシング部２４内に自己放電式除電ブラシ２５（以下単に除電ブラシ２５と称する）をブラシの先端がブレード２０に接するように設けているものである。本実施の形態ではブレード２０は、帯電防止材入りの樹脂で構成しており、その固有抵抗は約１０6〜１０7Ω−ｃｍ程度となっているものである。 (Embodiment 2)
Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 4 shows a second embodiment of the second means of the present invention. In the present embodiment, a self-discharge type static elimination brush 25 (hereinafter simply referred to as a static elimination brush 25) is provided in the casing 24 so that the tip of the brush contacts the blade 20. In this embodiment, the blade 20 is made of a resin containing an antistatic material, and has a specific resistance of about 10 6 to 10 7 Ω-cm.

　以下、本実施の形態の動作について説明する。ケーシング部２４内に設けている除電ブラシ２５は、静電気による電荷を放電して除電するように作用するものである。本実施の形態のブレード２０は、１回転する毎にこの除電ブラシの先端に接触するようになっている。一方、ブレード２０と絨毯表面との摩擦によって絨毯表面に発生していた静電気による電荷は、ブレード２０が接触する都度ブレード２０に移行するものである。つまり、固有抵抗が前記１０6〜１０7Ω−ｃｍ程度の物体が帯電体に接触すると、帯電体の電荷がこの物体の表面に移動するものである。つまり、絨毯表面に発生している静電気による電荷は、ブレード２０が回転する毎にブレード２０に移動し、更に除電ブラシ２５のブラシ先端部が接触する都度放電されることになるものである。また、ケーシング部２４が吸い込んだ塵埃は除電ブラシ２５とすぐに接触して除電されるため、ケーシング部２４が帯電することはないものである。 Hereinafter, the operation of the present embodiment will be described. The static elimination brush 25 provided in the casing portion 24 functions to discharge the charge due to static electricity and eliminate the charge. The blade 20 according to the present embodiment comes into contact with the tip of the charge removing brush every one rotation. On the other hand, the charge due to the static electricity generated on the carpet surface due to the friction between the blade 20 and the carpet surface is transferred to the blade 20 every time the blade 20 comes into contact. That is, when an object having a specific resistance of about 10 6 to 10 7 Ω-cm contacts the charged body, the charge of the charged body moves to the surface of the object. In other words, the charge caused by the static electricity generated on the carpet surface moves to the blade 20 every time the blade 20 rotates, and is discharged each time the brush tip of the neutralization brush 25 comes into contact. Further, since the dust sucked by the casing portion 24 comes into immediate contact with the charge removing brush 25 and is discharged, the casing portion 24 is not charged.

　以上のように本実施の形態によれば、前記実施の形態と同様絨毯表面と床ノズルの外面が帯電することはなく、しかも前記実施の形態のような高電圧発生回路を使用する必要のない簡単な構成で、集塵性能の高い掃除機用床ノズルとして作用するものである。またケーシング部１６に帯電することもないため、床ノズル外面に塵埃が付着して美観をそこねたり、使用者が床ノズルに触れて電気ショックを感じるなどの問題点もなく、安全性の高い掃除機用床ノズルを実現するものである。 As described above, according to the present embodiment, the carpet surface and the outer surface of the floor nozzle are not charged similarly to the above-described embodiment, and further, it is not necessary to use the high voltage generation circuit as in the above-described embodiment. With a simple configuration, it functions as a floor nozzle for a vacuum cleaner having high dust collection performance. Also, since the casing portion 16 is not charged, there is no problem that dust adheres to the outer surface of the floor nozzle to make the appearance unsightly, and a user touches the floor nozzle and feels an electric shock, and has high safety. It is intended to realize a floor nozzle for a vacuum cleaner.

　以上のように本発明の掃除機用床ノズルは、集塵性能を向上できるので、家庭用、業務用を問わず、吸込部を有する掃除機全般に有用である。 As described above, the floor nozzle for a vacuum cleaner of the present invention can improve the dust collecting performance, and is useful for general vacuum cleaners having a suction portion regardless of whether it is for home use or business use.
