　図５に示すように、タービン２６は、吸込具本体２１の後方に設けられている。 As shown in FIG. 5, the turbine 26 is provided behind the suction tool main body 21.
　回転ブラシ２７は、吸込室２５内に設置されており、タービン２６と連動して回転自在に回転するように設けられている。回転ブラシ２７の外周には、ブラシ毛２８が設けられている。ブラシ毛２８は、回転ブラシ２７の外周に螺旋状に植毛されている。 The rotating brush 27 is installed in the suction chamber 25 and is provided so as to rotate freely in conjunction with the turbine 26. Brush hairs 28 are provided on the outer periphery of the rotating brush 27. The brush hairs 28 are spirally implanted on the outer periphery of the rotating brush 27.
　図６に示すように、突出部２９は、補助吸込口体３０の前方下部に設けられている。突出部２９の形状は、後方から前方に向けて高さ方向の幅が小さくなるように形成されている。突出部２９の形状は、舌状つまり、後方から前方に向けて先細りの形状である。 As shown in FIG. 6, the protruding portion 29 is provided at the lower front portion of the auxiliary suction port body 30. The shape of the protrusion 29 is formed such that the width in the height direction decreases from the rear to the front. The protrusion 29 has a tongue shape, that is, a shape that tapers from the rear to the front.
　補助吸込口体３０は、図６に示すように、吸込具本体２１の外郭に設けられている。補助吸込口体３０は、吸込具本体２１の前方に設けられている。 The auxiliary suction port body 30 is provided on the outer shell of the suction tool body 21 as shown in FIG. The auxiliary suction port body 30 is provided in front of the suction tool main body 21.
　隙間３１は、補助吸込口体３０の突出部２９の底面部４８と、被清掃面との間の部分である。被清掃面は、水平かつ平坦な床などの、電気掃除機を用いて清掃を行う面である。 The gap 31 is a portion between the bottom surface portion 48 of the protruding portion 29 of the auxiliary suction port body 30 and the surface to be cleaned. The surface to be cleaned is a surface that is cleaned using a vacuum cleaner, such as a horizontal and flat floor.
　図６に示すように、底面部４８は、隙間３１が、突出部２９の後方から前方に向けて広くなる部分を有するよう設けられている。傾斜部３２は、突出部２９の底面部４８に形成されている。 As shown in FIG. 6, the bottom surface portion 48 is provided so that the gap 31 has a portion that widens from the rear to the front of the protruding portion 29. The inclined portion 32 is formed on the bottom surface portion 48 of the protruding portion 29.
　傾斜角度３３は、傾斜部３２と、被清掃面とにより成す角度を示す。傾斜角度３３は、５度から５０度の範囲に設定されている。 The inclination angle 33 indicates an angle formed by the inclined portion 32 and the surface to be cleaned. The inclination angle 33 is set in the range of 5 degrees to 50 degrees.
　このように構成された電気掃除機用吸込具２０の突出部２９は、図９に示すように、ソファ４７等の座部４７ａと、背もたれ部４７ｂとの間の隙間に挿入される。 The protruding portion 29 of the vacuum cleaner suction tool 20 configured as described above is inserted into a gap between the seat 47a such as the sofa 47 and the backrest 47b as shown in FIG.
　このように、突出部２９が隙間３１を有するように備えられていることにより、座部４７ａと背もたれ部４７ｂとの間に入り込んだ塵埃へ、集塵気流が到達しやすくなる。集塵気流により、塵埃には集塵作用が発生する。これにより、塵埃を効率よく集塵することができる。 Thus, by providing the protruding portion 29 so as to have the gap 31, the dust collection airflow easily reaches the dust that has entered between the seat portion 47a and the backrest portion 47b. A dust collecting action is generated in the dust due to the dust collecting airflow. Thereby, dust can be collected efficiently.
　さらに、本実施の形態における電気掃除機用吸込具２０の底面部４８は、図６に示すように、突出部２９の被清掃面と垂直方向の幅が、突出部２９の後方から前方にかけて小さくなるよう形成された部分を有している。 Furthermore, as shown in FIG. 6, the bottom surface portion 48 of the vacuum cleaner suction tool 20 in the present embodiment has a width in the direction perpendicular to the surface to be cleaned of the protrusion 29 that decreases from the rear to the front of the protrusion 29. It has the part formed so that it may become.
　ここで、突出部２９の被清掃面と垂直方向の幅とは、側面から見たときの突出部２９の高さ方向の厚みの幅を示す。突出部２９の先端部の厚みの幅は、接続パイプ２４側の幅よりも薄くなる部分を有するように構成している。 Here, the width in the direction perpendicular to the surface to be cleaned of the protruding portion 29 indicates the width of the thickness in the height direction of the protruding portion 29 when viewed from the side. The width of the thickness of the tip portion of the protruding portion 29 is configured to have a portion that is thinner than the width on the connection pipe 24 side.
　このような構成により、図９に示すように、突出部２９は、ソファ４７等の座部４７ａと、背もたれ部４７ｂとの間の隙間に挿入し易くなる。これは、突出部２９の先端部の厚みの幅は、突出部２９の進行方向において吸気口４１（図４）が設けられている側における厚みの幅よりも小さいためである。 With this configuration, as shown in FIG. 9, the protruding portion 29 can be easily inserted into the gap between the seat 47a such as the sofa 47 and the backrest 47b. This is because the width of the thickness of the tip of the protrusion 29 is smaller than the width of the thickness on the side where the air inlet 41 (FIG. 4) is provided in the traveling direction of the protrusion 29.
　さらに、突出部２９を奥に挿入するにつれ、ソファ４７等の座部４７ａと、背もたれ部４７ｂとの隙間が広がる。これにより、奥に堆積した塵埃をさらに集塵しやすくすることができる。 Furthermore, as the protrusion 29 is inserted into the back, the gap between the seat 47a such as the sofa 47 and the backrest 47b increases. Thereby, it is possible to further easily collect dust accumulated in the back.
　また、本実施の形態における電気掃除機用吸込具２０の突出部２９の底面部４８は、底面部４８と被清掃面との隙間の被清掃面と垂直方向の高さが、突出部２９の後方から前方に向けて大きくなるよう形成された部分を有するよう形成されていればよい。 In addition, the bottom surface 48 of the protrusion 29 of the vacuum cleaner suction tool 20 according to the present embodiment has a height in the direction perpendicular to the surface to be cleaned of the gap between the bottom surface 48 and the surface to be cleaned. What is necessary is just to form so that it may have a part formed so that it may become large toward back from the back.
　このように構成することにより、突出部２９を、ソファ４７等の座部４７ａと、背もたれ部４７ｂとの間に押し込むことができる。これにより、座部４７ａと背もたれ部４７ｂとの間の隙間を上方に広げることができる。このため、突出部２９の底面部４８には、さらに隙間が生じやすくなる。 With this configuration, the protruding portion 29 can be pushed between the seat 47a such as the sofa 47 and the backrest 47b. Thereby, the clearance gap between the seat part 47a and the backrest part 47b can be expanded upwards. For this reason, a gap is more likely to occur in the bottom surface portion 48 of the protruding portion 29.
　この隙間により、集塵気流が塵埃まで届き易くなる。これにより、塵埃をさらに効率よく集塵することができる。 This gap makes it easier for the dust collection airflow to reach the dust. Thereby, dust can be collected more efficiently.
　図６に示すように、突出部２９の底面部４８には、傾斜部３２が設けられている。 As shown in FIG. 6, an inclined portion 32 is provided on the bottom surface portion 48 of the protruding portion 29.
　隙間３１の高さは、突出部２９の底面部４８と被清掃面との間の被清掃面と垂直方向の高さを示している。つまり、隙間３１の高さは、突出部２９の一部と、被清掃面との被清掃面と垂直方向の距離を示す。隙間３１は、突出部２９の後方から前方に向けて大きくなるように設けられている。 The height of the gap 31 indicates the height in the direction perpendicular to the surface to be cleaned between the bottom surface 48 of the protrusion 29 and the surface to be cleaned. That is, the height of the gap 31 indicates a distance in a direction perpendicular to the surface to be cleaned between a part of the protruding portion 29 and the surface to be cleaned. The gap 31 is provided so as to increase from the rear to the front of the protruding portion 29.
　このように構成された突出部２９は、使用する際には、ソファ４７等の座部４７ａと、背もたれ部４７ｂとの間に挿入される。これによれば、突出部２９の底面部４８と、ソファ４７表面との空間を確実に確保することができる。このため、塵埃を効率よく集塵することができる。 The protrusion 29 configured in this manner is inserted between the seat 47a such as the sofa 47 and the backrest 47b when used. According to this, the space between the bottom surface portion 48 of the projecting portion 29 and the surface of the sofa 47 can be reliably ensured. For this reason, dust can be collected efficiently.
　これにより、座部４７ａと、背もたれ部４７ｂとの間に、突出部２９を挿入する作業性が、損なわれにくくなる。 Thus, the workability of inserting the protruding portion 29 between the seat portion 47a and the backrest portion 47b is not easily impaired.
　さらに、突出部２９の後方から前方に向けて大きくなるよう形成された部分は、突出部２９の底面部４８は、後方から前方に向けて被清掃面に対し、上方に反り返る傾斜面を有するように設けてもよい。 Furthermore, the part formed so that it may become large toward the front from the back of the protrusion part 29 seems to have the inclined surface where the bottom face part 48 of the protrusion part 29 curves upwards with respect to a to-be-cleaned surface toward the front from back. May be provided.
　また、大プーリー３４は、図５のように、回転ブラシ２７の一方の端部付近に設けられている。タービン２６は、接続パイプ２４の内部に収容されている。タービン室３５は、接続パイプ２４内部と、上本体部２２および下本体部２３とで囲まれた空間によって構成されている。 Further, the large pulley 34 is provided near one end of the rotating brush 27 as shown in FIG. The turbine 26 is accommodated in the connection pipe 24. The turbine chamber 35 is configured by a space surrounded by the inside of the connection pipe 24 and the upper main body portion 22 and the lower main body portion 23.
　図８に示すように、タービン室３５内には、タービン２６と、タービン軸３６と、タービン軸受（図示せず）とが設けられている。 As shown in FIG. 8, a turbine 26, a turbine shaft 36, and a turbine bearing (not shown) are provided in the turbine chamber 35.
　タービン２６は、タービン室３５に設置されている。回転ブラシ２７は、動力源であるタービン２６により駆動する。 The turbine 26 is installed in the turbine chamber 35. The rotating brush 27 is driven by a turbine 26 that is a power source.
　タービン軸３６は、タービン２６の回転中心に圧入固定されて設けられている。タービン軸３６は、タービン軸受（図示せず）に挿入され回転自在に設けられている。小プーリー３７は、タービン軸３６のタービン２６と反対側に設けられている。 The turbine shaft 36 is press-fitted and fixed at the rotation center of the turbine 26. The turbine shaft 36 is rotatably inserted into a turbine bearing (not shown). The small pulley 37 is provided on the opposite side of the turbine shaft 36 from the turbine 26.
　タービン軸受は、タービン室３５にて上本体部２２と下本体部２３とで挟持されている。 The turbine bearing is sandwiched between the upper main body 22 and the lower main body 23 in the turbine chamber 35.
　外気導入口３８は、図８に示すように、上本体部２２の上面に、外気と連通するように設けられている。外気導入口３８は、前方が開放するように設けられている。 As shown in FIG. 8, the outside air introduction port 38 is provided on the upper surface of the upper main body portion 22 so as to communicate with outside air. The outside air introduction port 38 is provided so that the front is opened.
　通風流路３９は、上本体部２２と下本体部２３との間に設けられている。通風流路３９は、外気導入口３８と、タービン室３５とを連通するように設けられている。通風流路３９は、タービン２６を駆動させる流入風を取り入れる。 The ventilation channel 39 is provided between the upper main body 22 and the lower main body 23. The ventilation channel 39 is provided so as to communicate the outside air inlet 38 and the turbine chamber 35. The ventilation passage 39 takes in the inflow air that drives the turbine 26.
　また、図５に示すように、ベルト４０は、小プーリー３７と、大プーリー３４とを張架するように設けられている。タービン２６の駆動力は、ベルト４０を介して回転ブラシ２７に伝達される。 Further, as shown in FIG. 5, the belt 40 is provided so as to stretch a small pulley 37 and a large pulley 34. The driving force of the turbine 26 is transmitted to the rotating brush 27 via the belt 40.
　このように構成された掃除機本体４の動作についてさらに詳細に説明する。 The operation of the cleaner body 4 configured in this way will be described in more detail.
　吸込具本体２１を被掃除面に置いた状態で、掃除機本体４の動作を開始させると、吸引風が発生する。吸引風は、接続パイプ２４を介して、吸込具本体２１の吸込室２５に流入する。下本体部２３の下面の開口部には、塵埃を吸引する吸塵風が発生する。 If the operation of the cleaner body 4 is started with the suction tool body 21 placed on the surface to be cleaned, suction air is generated. The suction air flows into the suction chamber 25 of the suction tool main body 21 through the connection pipe 24. In the opening on the lower surface of the lower main body portion 23, a dust-absorbing wind that sucks dust is generated.
　さらに、図７に示すように外気導入口３８からは、通風流路３９（図８）を介してタービン２６を駆動する駆動風が発生する。そして、回転ブラシ２７は、タービン２６の駆動により回転する。回転ブラシ２７は、ベルト４０を介して回転する。これにより、回転ブラシ２７は、絨毯上などの塵埃をかき上げる。 Further, as shown in FIG. 7, driving air for driving the turbine 26 is generated from the outside air introduction port 38 via the ventilation passage 39 (FIG. 8). The rotating brush 27 is rotated by driving the turbine 26. The rotating brush 27 rotates via the belt 40. Thereby, the rotating brush 27 scoops up dust on the carpet or the like.
　上述のように第１の実施の形態では、電気掃除機用吸込具２０の吸込具本体２１内には、タービン２６と、回転ブラシ２７とを備えた形態を一例として説明を行った。 As described above, in the first embodiment, an example in which the turbine 26 and the rotating brush 27 are provided in the suction tool main body 21 of the vacuum cleaner suction tool 20 has been described.
　しかし、これに限られることなく、吸込具本体２１内にタービン２６と回転ブラシ２７を備えていない形態の電気掃除機用吸込具２０においても、上述と同様な効果を得ることができる。 However, the present invention is not limited to this, and the same effect as described above can be obtained also in the vacuum cleaner suction tool 20 in which the turbine 26 and the rotating brush 27 are not provided in the suction tool main body 21.
　第１の実施の形態において、突出部２９が、後方から前方に向けて、なだらかな傾斜状になるように設けられている構成について説明を行った。しかしながら、本発明は、この構成に限定されるものではない。例えば、突出部２９の底面部４８が、後方から前方に向けて、一部に傾斜を有するように設けられていてもよい。この構成とすれば、突出部２９を、ソファ４７等の座部４７ａと、背もたれ部４７ｂとの間の隙間に挿入できるからである。 In the first embodiment, the configuration in which the projecting portion 29 is provided so as to have a gentle slope from the rear to the front has been described. However, the present invention is not limited to this configuration. For example, the bottom surface portion 48 of the projecting portion 29 may be provided so as to be partially inclined from the rear to the front. This is because the protrusion 29 can be inserted into the gap between the seat 47a such as the sofa 47 and the backrest 47b.
　また、第１の実施の形態においては、傾斜角度３３は、前述の範囲に設定されている。しかし、本発明は、この構成に限定されるものではない。傾斜角度３３は、突出部２９が、ソファ４７等の座部４７ａと、背もたれ部４７ｂとの間の隙間に挿入しやすい角度であればよい。 Further, in the first embodiment, the inclination angle 33 is set in the above-described range. However, the present invention is not limited to this configuration. The inclination angle 33 may be an angle at which the protruding portion 29 can be easily inserted into the gap between the seat portion 47a such as the sofa 47 and the backrest portion 47b.
　（第２の実施の形態）
　本発明の第２の実施の形態に係る電気掃除機用吸込具２０は、基本的には、第１の実施の形態に係る電気掃除機用床吸込具と同様の構成を有している。 (Second Embodiment)
The vacuum cleaner suction tool 20 according to the second embodiment of the present invention basically has the same configuration as the vacuum cleaner floor suction tool according to the first embodiment.
　本実施の形態の吸込具本体２１は、前方下部に吸込室２５と連通する吸気口４１を備えている。また、空間部４２は、突出部２９の底面部４８に構成している。また、突出部２９の底面部４８に、ブラシ体４３を設けている。 The suction tool main body 21 of the present embodiment includes an intake port 41 communicating with the suction chamber 25 at the lower front part. The space 42 is formed on the bottom surface 48 of the protrusion 29. Further, a brush body 43 is provided on the bottom surface portion 48 of the protruding portion 29.
　本実施の形態に係る電気掃除機用吸込具２０の具体的な構成について、図４、図８、図９を参照して説明する。 A specific configuration of the vacuum cleaner suction tool 20 according to the present embodiment will be described with reference to FIGS. 4, 8, and 9.
　本実施の形態に係る電気掃除機用吸込具２０は、吸込具本体２１の前方下部に、図４に示すように、吸気口４１を備えている。吸気口４１は、吸込室２５と連通するように設けられている。 The vacuum cleaner suction tool 20 according to the present embodiment includes a suction port 41 at the lower front portion of the suction tool body 21 as shown in FIG. The intake port 41 is provided so as to communicate with the suction chamber 25.
　図４のように吸込具本体２１に補助吸込口体３０を取り付けた状態において、空間部４２は、突出部２９の底面部４８（図６）に設けられている。突出部２９の底面部４８（図６）と、被清掃面との隙間３１（図６）から吸引される外気は吸気口４１（図６）に導かれる。 In the state where the auxiliary suction port body 30 is attached to the suction tool body 21 as shown in FIG. 4, the space portion 42 is provided on the bottom surface portion 48 (FIG. 6) of the protruding portion 29. The outside air sucked from the gap 31 (FIG. 6) between the bottom surface portion 48 (FIG. 6) of the protruding portion 29 and the surface to be cleaned is guided to the intake port 41 (FIG. 6).
　図４に示すように、本実施の形態における電気掃除機用吸込具２０は、吸込具本体２１の前方下部に吸込室２５と連通する吸気口４１と、突出部２９の底面部４８に設けられた空間部４２とを備えている。空間部４２は、吸込具本体２１に補助吸込口体３０を有した状態において、底面部４８（図６）と被清掃面との隙間３１（図６）から吸引される外気を吸気口４１に導くよう形成されている。 As shown in FIG. 4, the vacuum cleaner suction tool 20 according to the present embodiment is provided at the lower front portion of the suction tool body 21 at the intake port 41 communicating with the suction chamber 25 and the bottom surface portion 48 of the protrusion 29. The space part 42 is provided. In the state where the suction tool main body 21 has the auxiliary suction port body 30, the space portion 42 allows outside air sucked from the gap 31 (FIG. 6) between the bottom surface portion 48 (FIG. 6) and the surface to be cleaned to the suction port 41. Shaped to guide.
　このように、吸気口４１から塵埃に対して働く集塵気流の強さは、空間部４２によって実質的に均一にすることができる。つまり、空間部４２の内部に存在する塵埃であれば、集塵気流が実質的に均一に働く。このため、ソファ４７等の座部４７ａと、背もたれ部４７ｂとの間に入り込んだ塵埃に対し、集塵気流は、均一に作用する。吸気口４１が空間部４２内の塵埃を吸込室２５まで強力に導かれる。集塵作用により、塵埃を効率よく集塵することができる。 Thus, the strength of the dust collection airflow acting on the dust from the air inlet 41 can be made substantially uniform by the space portion 42. That is, if the dust is present inside the space portion 42, the dust collection airflow works substantially uniformly. For this reason, the dust collection airflow acts uniformly on the dust that has entered between the seat 47a such as the sofa 47 and the backrest 47b. The inlet 41 strongly guides the dust in the space 42 to the suction chamber 25. Due to the dust collecting action, dust can be collected efficiently.
　さらに、本実施の形態における電気掃除機用吸込具２０は、突出部２９の底面部４８（図６）に、ブラシ体４３（図８）が設けられている。 Furthermore, the vacuum cleaner suction tool 20 in the present embodiment is provided with a brush body 43 (FIG. 8) on the bottom surface portion 48 (FIG. 6) of the protruding portion 29.
　ブラシ体４３は、図４および図８に示すように、突出部２９の底面部４８の前方に設けられている。 The brush body 43 is provided in front of the bottom surface portion 48 of the protruding portion 29 as shown in FIGS.
　突出部２９の底面部４８を、被清掃面に押し付けた状態で、吸込具本体２１を前後に動作させる。ブラシ体４３により、例えば被清掃面である絨毯上に絡み付いた糸屑や髪の毛、ペット動物の毛等の塵埃等を、掻き上げて剥離させることができる。 The suction tool main body 21 is moved back and forth with the bottom surface 48 of the protruding portion 29 pressed against the surface to be cleaned. With the brush body 43, for example, dust such as lint, hair, and pet animal hair entangled on the carpet that is the surface to be cleaned can be scraped and peeled off.
　剥離された糸や、毛状などの塵埃は、突出部２９の底面部４８に設けられた空間部４２に流入する。塵埃は、吸気口４１を介して吸込室２５に吸引される。これにより、効率よく集塵することができる。 The peeled thread or hairy dust flows into the space 42 provided on the bottom surface 48 of the protrusion 29. Dust is sucked into the suction chamber 25 through the air inlet 41. Thereby, dust can be collected efficiently.
　（第３の実施の形態）

The shape of the locking portion 44 has a substantially triangular triangular convex portion. The acute angle vertex of the convex part of the acute angle triangle is arranged in front of the suction tool main body 21 so that the acute angle vertex is located.
　被係止部４５は、図１１に示すように、実質的に同形状の開口部を有している。 As shown in FIG. 11, the locked portion 45 has an opening having substantially the same shape.
　補助吸込口体３０は、吸込具本体２１の前方方向から装着する。このとき、三角形の鋭角を成す２辺の傾斜と、係止部４４とが、嵌り込む。つまり、係止部４４が有している鋭角三角形の凸状部に、被係止部４５である開口部が挿入される。このような構成により、補助吸込口体３０（図１１）は、吸込具本体２１（図１０）の外郭に着脱自在に取り付けられる。 The auxiliary suction port body 30 is mounted from the front side of the suction tool body 21. At this time, the inclination of the two sides forming the acute angle of the triangle and the engaging portion 44 are fitted. That is, the opening which is the locked portion 45 is inserted into the acute triangular convex portion of the locking portion 44. With such a configuration, the auxiliary suction port body 30 (FIG. 11) is detachably attached to the outer shell of the suction tool body 21 (FIG. 10).
　鋭角三角形の凸状部は、実質的に同形状の開口部が嵌り込みやすくなるようなガイドとして働く。これにより、補助吸込口体３０と、吸込具本体２１とは、装着し易くすることができる。 The convex part of the acute triangle serves as a guide that makes it easy to fit the substantially identical opening. Thereby, the auxiliary | assistant suction inlet 30 and the suction tool main body 21 can be made easy to mount | wear.
