この付勢部材５４によって第２清掃部５２は第１清掃部５１に対して軸５２ｃを中心として第１清掃部５１から離間する方向へ付勢されている（図４（Ａ）と（Ｂ）参照）。 A compression coil spring is used as the biasing member 54 in this embodiment, and the first rear end portion 51b of the first cleaning portion 51 and the second rear end portion 52b of the second cleaning portion 52 are recessed. 52g. Note that the biasing member 54 is not limited to a compression coil spring, and may be, for example, a leaf spring, an elastic foam, or the like.
The biasing member 54 biases the second cleaning portion 52 toward the first cleaning portion 51 in a direction away from the first cleaning portion 51 about the shaft 52c (FIGS. 4A and 4B). reference).

＜清掃時の吸引ノズルの作用効果について＞
図４（Ａ）と（Ｂ）に示すように、吸引ノズル５０の第２清掃部５２が被清掃面から浮き上がった第１清掃モードでは、付勢部材５４にて第２清掃部５２が軸５２ｃを中心として第１清掃部５１から離間する揺動方向に付勢されている。このとき、第２清掃部５１の嵩高部５２ｆは第１清掃部５１の当接壁部５１ｈから離間しているため、第１吸引口５１ｆと連通口５１ｅとが第１通風路５１ｇを介して連通している。この際、嵩高部５２ｆの上面によって第１通風路５１ｇの一部が構成されている。一方、第２清掃部５２の連通口５２ｉは第１清掃部５１の閉鎖壁部５１ｉの位置に移動して閉鎖されている。 <Effects of the suction nozzle during cleaning>
As shown in FIGS. 4A and 4B, in the first cleaning mode in which the second cleaning portion 52 of the suction nozzle 50 is lifted from the surface to be cleaned, the biasing member 54 causes the second cleaning portion 52 to move toward the shaft 52c. is biased in a swinging direction away from the first cleaning portion 51 . At this time, since the bulky portion 52f of the second cleaning portion 51 is separated from the contact wall portion 51h of the first cleaning portion 51, the first suction port 51f and the communication port 51e are connected via the first ventilation passage 51g. are in communication. At this time, the upper surface of the bulky portion 52f constitutes part of the first ventilation passage 51g. On the other hand, the communication port 52i of the second cleaning section 52 moves to the position of the closing wall section 51i of the first cleaning section 51 and is closed.

したがって、掃除機本体１０（図１参照）を駆動させて吸引力を発生させ、第１清掃モードにおける第１清掃部５１の第１吸引口５１ｆを被清掃個所（例えば、床面と壁面との間の隅部、階段の隅部等）に近づけると、被清掃個所の塵埃が空気と共に第１吸引口５１ｆに吸い込まれ、第１通風路５１ｇ、第３通風路５３ａｘおよび延長パイプ８０を介して掃除機本体１０の集塵装置３０へ送られる。このとき、仕切壁５１ｊを設けることにより、軸５２ｃの周囲における第１清掃部５１と第２清掃部５２との間の隙間を小さくし、この隙間から空気が第１通風路５１ｇ内に流入して第１吸引口５１ｆの吸引力が低下するのを抑制することができる。それに加え、軸５２ｃに塵埃が絡みついて第１清掃部５１に対する第２清掃部５２の揺動が妨げられる不具合を抑制することができる。 Therefore, the vacuum cleaner main body 10 (see FIG. 1) is driven to generate a suction force, and the first suction port 51f of the first cleaning unit 51 in the first cleaning mode is moved to the part to be cleaned (for example, between the floor surface and the wall surface). When the dust on the part to be cleaned is brought close to the corner of the space, the corner of the stairs, etc.), the dust on the part to be cleaned is sucked into the first suction port 51f together with the air, and passes through the first ventilation passage 51g, the third ventilation passage 53ax and the extension pipe 80. It is sent to the dust collector 30 of the cleaner body 10 . At this time, by providing the partition wall 51j, the gap between the first cleaning section 51 and the second cleaning section 52 around the shaft 52c is made small, and air flows into the first ventilation passage 51g through this gap. Therefore, it is possible to suppress a decrease in the suction force of the first suction port 51f. In addition, it is possible to suppress the problem that dust is entangled with the shaft 52c and the rocking motion of the second cleaning unit 52 with respect to the first cleaning unit 51 is hindered.

また、図６に示すように、本実施形態の吸引ノズル５０は、第１清掃モードでの使用状態において、第１清掃部５１の第１吸引口５１ｆｘが第２清掃部５２よりもさらに前方へ突出するように構成されてもよい。この場合、口細形の第１吸引口５１ｆｘが第１清掃部５１と一体であってもよく、あるいは、口細形の第１吸引口５１ｆｘが第１清掃部５１と別体であってもよい。つまり、後者の場合、吸引ノズルは、図２～図５で説明した吸引ノズル５０を吸引ノズル本体として備えると共に、吸引ノズル本体の第１吸引口５１ｆに着脱可能な口細形のアタッチメントノズル５１Ａを備える。
第１吸引口５１ｆｘを口細形とすることにより、例えば、サッシのレールの溝のような狭い隙間に第１吸引口５１ｆｘを差し入れて清掃することができるため、狭い隙間を効率よくきれいに清掃することができる。 Further, as shown in FIG. 6, in the suction nozzle 50 of the present embodiment, the first suction port 51fx of the first cleaning section 51 is positioned further forward than the second cleaning section 52 when the suction nozzle 50 is used in the first cleaning mode. It may be configured to protrude. In this case, the narrow-mouthed first suction port 51fx may be integrated with the first cleaning portion 51, or the narrow-mouthed first suction port 51fx may be separate from the first cleaning portion 51. good. In other words, in the latter case, the suction nozzle includes the suction nozzle 50 described in FIGS. 2 to 5 as a suction nozzle main body, and a narrow-mouthed attachment nozzle 51A detachable from the first suction port 51f of the suction nozzle main body. Prepare.
By making the first suction port 51fx narrow, for example, the first suction port 51fx can be inserted into a narrow gap such as a rail groove of a sash for cleaning, so that the narrow gap can be cleaned efficiently and cleanly. be able to.

図５（Ａ）と（Ｂ）に示すように、吸引ノズル５０の第２清掃部５２が被清掃面Ｆに当接した第２清掃モードでは、第１清掃部５１を介して第２清掃部５２のブラシ５２ｊが被清掃面Ｆへ押し付けられる。
このとき、付勢部材５４の付勢力に抗して第１清掃部５１が第２清掃部５２側へ軸５２ｃを中心として接近する揺動方向に移動することにより、第２清掃部５２の嵩高部５２ｆが相対的に第１清掃部５１内へ挿通口５１ｄ（図４（Ｂ）参照）を通って進入し、嵩高部５２ｆの上面が当接壁部５１ｈに当接し、これにより第１通風路５１ｇが閉鎖される。また、第２清掃部５２の連通口５２ｉが閉鎖壁部５１ｉの位置から連通口５１ｅ側へ移動して第３通風路５３ａｘと連通する。また、第２清掃部５２の支持部５２ｂａが緩衝部材５２ｋを介して被清掃面Ｆに突き当たることにより、ブラシ５２ｊの過剰な毛倒れが抑制され、それによって第１清掃部５１の第２清掃部５２側への揺動不足が抑制される。この結果、第１通風路５１ｇの閉鎖不足による第１吸引口５１ｆからの吸引を抑制することができる。 As shown in FIGS. 5A and 5B, in the second cleaning mode in which the second cleaning portion 52 of the suction nozzle 50 is in contact with the surface to be cleaned F, the second cleaning portion A brush 52j of 52 is pressed against the surface F to be cleaned.
At this time, the first cleaning portion 51 moves toward the second cleaning portion 52 around the shaft 52c against the biasing force of the biasing member 54, thereby increasing the bulk of the second cleaning portion 52. The portion 52f relatively enters the first cleaning portion 51 through the insertion opening 51d (see FIG. 4(B)), and the upper surface of the bulky portion 52f contacts the contact wall portion 51h. Channel 51g is closed. Also, the communication port 52i of the second cleaning portion 52 moves from the position of the closing wall portion 51i toward the communication port 51e to communicate with the third ventilation passage 53ax. In addition, the supporting portion 52ba of the second cleaning portion 52 abuts against the surface to be cleaned F through the buffer member 52k, thereby suppressing the excessive fall of the brush 52j, thereby preventing the second cleaning portion of the first cleaning portion 51 from falling. Insufficient rocking to the 52 side is suppressed. As a result, suction from the first suction port 51f due to insufficient closure of the first air passage 51g can be suppressed.

したがって、第２清掃モードにおいては、第１清掃部５１の第１吸引口５１ｆによる吸引が停止し、被清掃面Ｆ上の塵埃が空気と共に第２清掃部５２の第２吸引口５２ｄへ吸引され、第２通風路５２ｅ、連通口５２ｉ、連通口５１ｅ、第３通風路５３ａｘおよび延長パイプ８０（図１参照）を介して掃除機本体１０の集塵装置３０へ送られる。このとき、吸引ノズル５０を被清掃面Ｆに沿って移動させてブラシ５２ｊを被清掃面Ｆに擦りつけることにより、被清掃面Ｆに付着した塵埃を掃き出して吸引除去することができる。また、第１清掃部５１に対する接続筒部５３の第１部材５３ａの傾斜角度および第１部材５３ａに対する第２部材５３ｂの傾斜角度を適宜調整することにより、例えば、空気調和機の室内機の上面、箪笥の上面、棚の上面等の高い位置にある被清掃面も容易に清掃することができる。 Therefore, in the second cleaning mode, the suction by the first suction port 51f of the first cleaning section 51 is stopped, and the dust on the surface to be cleaned F is sucked into the second suction port 52d of the second cleaning section 52 together with the air. , the second air passage 52e, the communication port 52i, the communication port 51e, the third air passage 53ax and the extension pipe 80 (see FIG. 1) to the dust collector 30 of the cleaner body 10. At this time, by moving the suction nozzle 50 along the surface to be cleaned F and rubbing the brush 52j against the surface to be cleaned F, the dust adhering to the surface to be cleaned F can be swept out and removed by suction. Further, by appropriately adjusting the inclination angle of the first member 53a of the connecting tube portion 53 with respect to the first cleaning portion 51 and the inclination angle of the second member 53b with respect to the first member 53a, for example, the upper surface of the indoor unit of the air conditioner can be , the upper surface of a chest of drawers, the upper surface of a shelf, and other surfaces to be cleaned at high positions can be easily cleaned.

また、本実施形態の吸引ノズル５０によれば、第１吸引口５１ｆの開口面積が狭く、かつ、第２吸引口５２ｄの開口面積が広くなっているため、第１吸引口５１ｆから塵埃を吸引する第１清掃モードでの吸引力と、第２吸引口５２ｄから塵埃を吸引する第２清掃モードでの吸引力とを異ならせることができる。なお、前記従来の電気掃除機ヘッド（特開２０１７－１３６３０３号公報）では、第２部品を第１部品に対して真っ直ぐな状態にしたブラシ使用時の第２風路の開口面積と、第２部品を第１部品に対して傾斜させたときの第１風路の開口面積とは同じである。そのため、第２風路にて塵埃を吸引するときの吸引力と、第１風路にて塵埃を吸引するときの吸引力とを変えることができない。 Further, according to the suction nozzle 50 of the present embodiment, since the opening area of the first suction port 51f is narrow and the opening area of the second suction port 52d is wide, dust is sucked from the first suction port 51f. The suction force in the first cleaning mode that is used to suck dust from the second suction port 52d can be made different from the suction force in the second cleaning mode that sucks dust from the second suction port 52d. In the conventional vacuum cleaner head (Japanese Patent Application Laid-Open No. 2017-136303), the opening area of the second air passage when using the brush in which the second part is straight with respect to the first part, It is the same as the opening area of the first air passage when the part is tilted with respect to the first part. Therefore, it is impossible to change the suction force for sucking dust in the second air passage and the suction force for sucking dust in the first air passage.

第２実施形態の吸引ノズル１５０は、第１清掃部１５１および第２清掃部１５２の構成が第１実施形態とは異なる以外は、第１実施形態と概ね同様に構成されている。
以下、第２実施形態における第１実施形態とは異なる点を主に説明する。 (Second embodiment)
FIG. 7A is a left side view of the suction nozzle of the second embodiment in the first cleaning mode, and FIG. 7B is a left sectional view in the second cleaning mode. In FIGS. 7A and 7B, elements similar to those in FIGS. 4A and 4B and FIGS. 5A and 5B are denoted by the same reference numerals.
The suction nozzle 150 of the second embodiment is generally configured in the same manner as in the first embodiment, except that the configurations of the first cleaning section 151 and the second cleaning section 152 are different from those of the first embodiment.
In the following, the differences between the second embodiment and the first embodiment will be mainly described.

図７（Ａ）と（Ｂ）を参照しながら第２実施形態の吸引ノズル１５０の構成を説明する。
まず、第２清掃部１５２は、第２前端部５２ａ側に設けられた第１嵩高部１５２ｃと、第２後端部５２ｂ側に設けられた陥没部５２ｇと、第１嵩高部１５２ｃと陥没部５２ｇとの間に設けられた第１嵩高部１５２ｃよりも高い第２嵩高部１５２ｆと、第２通風路１５２ｇと連通するように第２嵩高部１５２ｆにおける陥没部５２ｇ側の面に設けられた連通口１５２ｈとを有する。 The configuration of the suction nozzle 150 of the second embodiment will be described with reference to FIGS. 7(A) and 7(B).
First, the second cleaning portion 152 includes a first bulky portion 152c provided on the side of the second front end portion 52a, a depressed portion 52g provided on the side of the second rear end portion 52b, and the first bulky portion 152c and the depressed portion. 52g and a second bulky portion 152f higher than the first bulky portion 152c, and a communication provided on the surface of the second bulky portion 152f on the recessed portion 52g side so as to communicate with the second ventilation passage 152g. and a mouth 152h.

第１清掃部１５１は、軸５２ｃを中心に第２清掃部１５２が揺動して第２清掃モード（図７（Ｂ）参照）に切り替わったときに第２嵩高部１５２ｆを第１通風路１５１ａ側へ挿通させる挿通口１５１ｂと、第２清掃モードでの第２嵩高部１５２ｆと当接するよう第１通風路１５１ａ内に設けられた当接壁部５１ｈと、第１清掃モード（図７（Ａ）参照）での第２清掃部１５２の連通口１５２ｈを閉鎖するよう挿通口１５１ｂの内周縁に設けられた閉鎖壁部５１ｉとを有する。なお、第２実施形態の場合、第１清掃部１５１の仕切壁１５１ｊは円筒面部５１ｃの近傍まで延びており、仕切壁１５１ｊと閉鎖壁部５１ｉとの間が挿通口１５１ｂとされている。 The first cleaning portion 151 moves the second bulky portion 152f to the first ventilation path 151a when the second cleaning portion 152 swings about the shaft 52c and switches to the second cleaning mode (see FIG. 7B). an insertion opening 151b for insertion to the side, a contact wall portion 51h provided in the first ventilation passage 151a so as to contact the second bulky portion 152f in the second cleaning mode, and a first cleaning mode (see FIG. 7A ))), and a closing wall portion 51i provided on the inner peripheral edge of the insertion port 151b so as to close the communication port 152h of the second cleaning portion 152. FIG. In the case of the second embodiment, the partition wall 151j of the first cleaning portion 151 extends to the vicinity of the cylindrical surface portion 51c, and the insertion port 151b is formed between the partition wall 151j and the closing wall portion 51i.

第２実施形態の吸引ノズル１５０によれば、図７（Ａ）に示す第１清掃モードにおいて、第１通風路１５１ａが開いて第３通風路５３ａｘと連通し、かつ、第２通風路１５２ｇが遮断される。このとき、第１清掃部１５１は第２清掃部１５２側に仕切壁１５１ｊを有することにより、第１清掃部１５１と第２清掃部１５２との間の隙間から第１通風路１５１ａ内へ空気が流入しにくくなっているため、第１吸引口５１ｆの吸引力の低下が効果的に抑制される。また、軸５２ｃの周辺へ塵埃が吸い込まれないため、軸５２ｃに塵埃が絡み付いて第１清掃部１５１に対する第２清掃部１５２の揺動が妨げられるという不具合も効果的に抑制される。 According to the suction nozzle 150 of the second embodiment, in the first cleaning mode shown in FIG. blocked. At this time, since the first cleaning section 151 has the partition wall 151j on the second cleaning section 152 side, air flows into the first ventilation passage 151a from the gap between the first cleaning section 151 and the second cleaning section 152. Since it is difficult for the liquid to flow in, the reduction in the suction force of the first suction port 51f is effectively suppressed. In addition, since dust is not sucked into the periphery of the shaft 52c, the problem of dust entangling around the shaft 52c and hindering the second cleaning portion 152 from swinging with respect to the first cleaning portion 151 is effectively suppressed.

また、図７（Ｂ）に示す第２清掃モードにおいて、第２清掃部１５２の第２嵩高部１５２ｆが第１清掃部１５１の当接壁部５１ｈに当接することにより第１通風路１５１ａと第３通風路５３ａｘとの間が閉鎖され、かつ、第２通風路１５２ｇが連通口１５２ｈを介して第３通風路５１ｅと連通し、被清掃面Ｆ上の塵埃を第２吸引口５２ｄへ吸引することができる。 In the second cleaning mode shown in FIG. 7B, the second bulky portion 152f of the second cleaning portion 152 abuts against the contact wall portion 51h of the first cleaning portion 151, thereby separating the first air passage 151a and the first air passage 151a. 3 air passage 53ax is closed, and the second air passage 152g communicates with the third air passage 51e through the communication port 152h, sucking the dust on the surface to be cleaned F to the second suction port 52d. be able to.

第３実施形態の吸引ノズル２５０の場合、第１清掃部２５１および第２清掃部２５２が互いに平行状態で接近離間する方向に移動可能に結合していること以外は、第１実施形態と概ね同様に構成されている。
以下、第３実施形態における第１実施形態とは異なる点を主に説明する。 (Third Embodiment)
8A is a left side view of the suction nozzle of the third embodiment in the first cleaning mode, and FIG. 8B is a left sectional view in the second cleaning mode. In FIGS. 8A and 8B, elements similar to those in FIGS. 4A and 4B and FIGS. 5A and 5B are denoted by the same reference numerals.
The suction nozzle 250 of the third embodiment is substantially the same as the first embodiment, except that the first cleaning part 251 and the second cleaning part 252 are connected parallel to each other so as to move toward and away from each other. is configured to
In the following, the differences between the third embodiment and the first embodiment will be mainly described.

図８（Ａ）と（Ｂ）を参照しながら第３実施形態の吸引ノズル２５０の構成を説明する。
まず、第２清掃部２５２は、前後方向の中間部に設けられた嵩高部２５２ａと、第２通風路２５２ｂと連通するよう嵩高部２５２ａに設けられて第２後端部５２ｂ側へ開口する連通口２５２ｃとを有する。 The configuration of the suction nozzle 250 of the third embodiment will be described with reference to FIGS. 8(A) and 8(B).
First, the second cleaning portion 252 includes a bulky portion 252a provided in the middle portion in the front-rear direction, and a communicating portion 252a provided in the bulky portion 252a so as to communicate with the second ventilation passage 252b and opening toward the second rear end portion 52b. and a mouth 252c.

第１清掃部１５１は、第２清掃部１５２が第１清掃部１５１側へ移動して第２清掃モード（図８（Ｂ）参照）に切り替わったときに嵩高部２５２ａを第１通風路２５１ａ内に収納させるための挿通口２５１ｂと、第２清掃モードでの嵩高部２５２ａと当接する当接壁部５１ｈと、第１清掃モード（図８（Ａ）参照）での第２清掃部２５２の連通口２５２ｃを閉鎖する閉鎖壁部５１ｉとを有する。なお、第３実施形態の場合、第１清掃部２５１の仕切壁２５１ｅは円筒面部５１ｃの近傍まで延びており、仕切壁２５１ｅと閉鎖壁部５１ｉとの間が挿通口２５１ｂとされている。 The first cleaning section 151 moves the bulky portion 252a into the first ventilation passage 251a when the second cleaning section 152 moves toward the first cleaning section 151 and switches to the second cleaning mode (see FIG. 8B). a contact wall portion 51h that contacts the bulky portion 252a in the second cleaning mode; and communication between the second cleaning portion 252 in the first cleaning mode (see FIG. 8A). and a closing wall portion 51i closing the mouth 252c. In the case of the third embodiment, the partition wall 251e of the first cleaning portion 251 extends to the vicinity of the cylindrical surface portion 51c, and the insertion port 251b is formed between the partition wall 251e and the closing wall portion 51i.

第３実施形態の吸引ノズル２５０によれば、図８（Ａ）に示す第１清掃モードにおいて、第１通風路２５１ａが開いて第３通風路５３ａｘと連通し、かつ、第２通風路２５２ｂが遮断される。このとき、第１清掃部２５１は第２清掃部２５２側に仕切壁２５１ｅを有することにより、第１清掃部２５１と第２清掃部２５２との間の隙間から第１通風路２５１ａ内へ空気が流入しにくくなっているため、第１吸引口５１ｆの吸引力の低下が効果的に抑制される。また、第１清掃部２５１と第２清掃部２５２との間の隙間に塵埃が吸い込まれて堆積しないため、第１清掃部２５１に対する第２清掃部２５２の平行移動（本実施形態では上下方向への平行移動）が妨げられることがない。 According to the suction nozzle 250 of the third embodiment, in the first cleaning mode shown in FIG. blocked. At this time, since the first cleaning section 251 has the partition wall 251e on the second cleaning section 252 side, air flows into the first ventilation passage 251a from the gap between the first cleaning section 251 and the second cleaning section 252. Since it is difficult for the liquid to flow in, the reduction in the suction force of the first suction port 51f is effectively suppressed. In addition, since dust is not sucked into the gap between the first cleaning unit 251 and the second cleaning unit 252 and does not accumulate, the second cleaning unit 252 moves parallel to the first cleaning unit 251 (in the vertical direction in this embodiment). translation) is not disturbed.

また、図８（Ｂ）に示す第２清掃モードにおいて、第２清掃部２５２の嵩高部２５２ａが第１清掃部２５１の当接壁部５１ｈに当接することにより第１通風路２５１ａと第３通風路５３ａｘとの間が閉鎖され、かつ、第２通風路２５２ｂが連通口２５２ｃを介して第３通風路５３ａｘと連通し、被清掃面Ｆ上の塵埃を第２吸引口２５２ｂへ吸引することができる。 Further, in the second cleaning mode shown in FIG. 8B, the bulky portion 252a of the second cleaning portion 252 contacts the contact wall portion 51h of the first cleaning portion 251, thereby separating the first ventilation path 251a and the third ventilation path 251a. 53ax, and the second air passage 252b communicates with the third air passage 53ax through the communication port 252c, so that the dust on the surface to be cleaned F can be sucked into the second suction port 252b. can.

なお、図示省略するが、例えば、第１清掃部２５１の左右内側面にリブが設けられると共に、第２清掃部２５２の左右外側面には第１清掃部２５１の前記リブが嵌り込む上下方向のガイド溝が設けられており、各リブは各ガイド溝に沿って移動可能に係止することにより第２清掃部２５２の第１清掃部２５１からの脱落が防止される。 Although not shown, for example, ribs are provided on the left and right inner side surfaces of the first cleaning section 251, and the ribs of the first cleaning section 251 are fitted to the left and right outer side surfaces of the second cleaning section 252. Guide grooves are provided, and each rib is locked so as to be movable along each guide groove, thereby preventing the second cleaning section 252 from falling off from the first cleaning section 251 .

It may be provided at the first rear end portion 51b of the cleaning portion 51 (a position rearward of the cylindrical surface portion 51c).
According to this configuration, in the second cleaning mode, the first cleaning part 51 is supported on the surface to be cleaned F by the supporting part and the cushioning member. It becomes easier to adjust the inclination angle of the first member 53a of the connecting tube part 53 with respect to the cleaning part 51 or the inclination angle with respect to the first member 53a with respect to the second member 53b. The same applies to the second and third embodiments.

２．第１実施形態の吸引ノズル５０において、付勢部材５４の付勢力に抗して第１清掃部５１と第２清掃部５２とが互いに接近した第２清掃モードを維持するロック機構を設けてもよい。このロック機構としては、例えば、第１清掃部５１の第１後端部５１ｂに係止凸部を設けると共に、第２清掃部５２の第２後端部５２ｂにフック部材を設け、第２清掃モードのときにユーザーがフックを係止凸部に引っ掛けることによりロックされる構成が挙げられる。
