図中符号39は補助車輪であり、表面は起毛布で覆われている。   Reference numeral 39 in the figure denotes an auxiliary wheel whose surface is covered with a raised cloth.
次に本発明に係る電気掃除機を用いた掃除について説明する。   Next, cleaning using the electric vacuum cleaner according to the present invention will be described.
掃除の際には、まず、作業者は、掃除機本体52の本体吸込口54に、ホース体55、延長管59および床ブラシ1を順次連通接続する。   When cleaning, first, the operator connects the hose body 55, the extension pipe 59, and the floor brush 1 to the main body suction port 54 of the cleaner body 52 in order.
さらに、作業者が、掃除機本体52から電源コードを引き出して図示しないコンセントに接続した後、把持部57を把持して所定の設定ボタン58を操作すると、この設定ボタン58により設定された動作モードに応じて電動送風機53が駆動される。   Further, when the operator pulls out the power cord from the cleaner main body 52 and connects it to an unillustrated outlet, and then grips the grip portion 57 and operates the predetermined setting button 58, the operation mode set by the setting button 58 is set. Accordingly, the electric blower 53 is driven.
そして、作業者は、把持部57を把持して床面上で床ブラシ1を前後に走行させる。駆動車輪10a、10bは回転して、床ブラシ1の走行を助ける。   Then, the operator grips the grip portion 57 and causes the floor brush 1 to run forward and backward on the floor surface. The drive wheels 10a and 10b rotate to help the floor brush 1 travel.
床ブラシ1の走行により、吸込口8および車輪収容部11a、11bから塵埃を空気とともに吸い込む。   As the floor brush 1 travels, dust is sucked together with air from the suction port 8 and the wheel housing portions 11a and 11b.
このとき、摺接部9a、9bは下方に面しているので、摺接部9a、9bが被掃除面に当接し、さらに、摺接部9a、9bに取り付けられた長起毛布37a、37bを介して走行負荷を増加させることなく、床ブラシ1を滑らかに進退する。また、車輪13が床面に接触することで、安全装置17の機能によって、回転ブラシ7および駆動車輪10a、10bの回転が可能となっている。例えば、床ブラシ1を前方へと走行(前進)させた場合には、車輪13が前転(正転)し、床ブラシ1を後方へと走行(後退)させた場合には、車輪13が後転(逆転)するので、この車輪13の回転方向に応じて、モータ制御部がモータ16の回転方向を、車輪13の回転方向と同方向となるように制御する。   At this time, since the slidable contact portions 9a and 9b face downward, the slidable contact portions 9a and 9b abut against the surface to be cleaned, and the long raised cloths 37a and 37b attached to the slidable contact portions 9a and 9b. The floor brush 1 is smoothly advanced and retracted without increasing the travel load via the. Moreover, the rotation brush 7 and the drive wheels 10a and 10b can be rotated by the function of the safety device 17 because the wheel 13 is in contact with the floor surface. For example, when the floor brush 1 travels forward (forward), the wheel 13 rotates forward (forward rotation), and when the floor brush 1 travels backward (reverses), the wheel 13 Since the vehicle rotates backward (reverse rotation), the motor control unit controls the rotation direction of the motor 16 to be the same as the rotation direction of the wheel 13 according to the rotation direction of the wheel 13.
この結果、モータ16の回転が駆動プーリ27およびベルト28を介して従動プーリ26へと伝達されることで、この従動プーリ26と連結された一方の駆動車輪10aが、また、カップリング25aを介して回転ブラシ7、および、この回転ブラシ7に連結された他方の駆動車輪10bが、一体的に同方向へと回転する。   As a result, the rotation of the motor 16 is transmitted to the driven pulley 26 via the drive pulley 27 and the belt 28, so that one of the drive wheels 10a connected to the driven pulley 26 also passes through the coupling 25a. Thus, the rotating brush 7 and the other driving wheel 10b connected to the rotating brush 7 are integrally rotated in the same direction.
このとき、回転ブラシ7の回転に伴い、各清掃部材32が床面の塵埃を掻き取って吸込口8へと運ぶとともに、駆動車輪10a、10bに取り付けた短い毛の不繊布34a、34b、長い毛の不繊布35a、35bで除去された塵埃は連通溝部8aを介して吸込口8へと運ばれる。   At this time, along with the rotation of the rotating brush 7, each cleaning member 32 scrapes the dust on the floor surface and carries it to the suction port 8, and the short non-woven cloth 34a, 34b attached to the drive wheels 10a, 10b is long. Dust removed by the non-woven cloth 35a, 35b is carried to the suction port 8 through the communication groove 8a.
上記掃除過程で、摺接部9a、9bに接する被掃除面は、吸込口8に生じる負圧(吸引力)によって掃除しにくいが、図8に示す摺接部9a、9bに取り付けられた短起毛布36a、36b及び長起毛布37a、37bによって掃除され、床ブラシ1のほぼ全幅で掃除をすることができ、特に絨毯を掃除する場合には、摺接部9a、9bに接する絨毯表面に絡まる毛などは、吸込口8に生じる負圧(吸引力)によって除去しにくいが、短起毛布36a、36bの先端36aが、長起毛布37a、37bの先端37aとほぼ同一高さになり、床ブラシ1を後方へと走行(後退)時、短起毛布36a、36bの先端36aで絨毯表面に絡まる毛などを掻きとることができる。 In the cleaning process, the surface to be cleaned that contacts the sliding contact portions 9a and 9b is difficult to clean by the negative pressure (suction force) generated at the suction port 8, but the short surface attached to the sliding contact portions 9a and 9b shown in FIG. It is cleaned by the raised cloths 36a and 36b and the long raised cloths 37a and 37b, and can be cleaned with almost the entire width of the floor brush 1. Especially when the carpet is cleaned, the carpet surface in contact with the sliding contact portions 9a and 9b is used. tangled hair, etc., difficult to remove by the negative pressure generated in the suction port 8 (suction force), but short napped 36a, the tip 36a 1 of 36b is NagaOkoshi blankets 37a, substantially the same height as the tip 37a 1 of 37b will, when traveling on the floor brush 1 to the rear (backward), it is possible to scrape short napped 36a, and hair entangled carpet surface 36b of the tip 36a 1.
また、摺接部9a、9bの前側に短起毛布36a、36b、後側に長起毛布37a、37bを配置することで、床ブラシ1を後方へと走行(後退)時、長起毛布37a、37bで床ブラシ1を円滑に滑らせ、短起毛布36a、36bの先端36aで絨毯表面に絡まる毛などを掻きとるので、走行負荷を増加させることなく摺接部9a、9bの走行面の清掃が十分に行え、さらに、常時被清掃面と接触する長起毛布37a、37bは長い毛を用いているので、磨耗があっても長寿命化を図ることができる。 Further, by arranging the short raised cloths 36a and 36b on the front side of the sliding contact portions 9a and 9b and the long raised cloths 37a and 37b on the rear side, the long raised cloth 37a can be used when the floor brush 1 runs backward (retreats). , 37b at slipped floor brush 1 smoothly, short napped 36a, so scrape entangled hairs such as carpet surface 36b of the tip 36a 1, the sliding portion 9a without increasing the running load, the running surface of 9b The long raised cloths 37a and 37b that are always in contact with the surface to be cleaned use long hairs, so that the life can be extended even if they are worn.
本実施形態の床ブラシおよびこれを備えた電気掃除機によれば、走行負荷を増加させることなく摺接部の走行面の清掃が十分に行え、特に、絨毯に付着した毛などの除去も行える吸込口体およびこれを備えた電気掃除機が実現する。   According to the floor brush of this embodiment and a vacuum cleaner equipped with the same, the running surface of the sliding contact portion can be sufficiently cleaned without increasing the running load, and in particular, hair attached to the carpet can also be removed. A suction port body and a vacuum cleaner provided with the same are realized.
なお、上記構成は、アップライト形や床ブラシが搭載可能なハンディ形にも使用することが可能である。   In addition, the said structure can be used also for the handy type which can mount an upright type and a floor brush.
