次に、第１の実施形態の動作を説明する。 Next, the operation of the first embodiment will be described.

電気掃除機１が起動すると、電動送風機13が動作して負圧を発生させる。ユーザは操作部７を把持操作し、吸込口体６等から床面の塵埃を空気とともに吸い込む。その後、含塵空気は吸込口11から集塵部12へと吸い込まれ、集塵部12において塵埃が分離捕集される。塵埃が分離された空気は電動送風機13に吸い込まれ、電動送風機13を冷却した後、電動送風機13の排気口から排出口を介して掃除機本体２の外部へと排出される。 When the vacuum cleaner 1 is activated, the electric blower 13 operates to generate a negative pressure. The user grips and operates the operation unit 7 and sucks dust on the floor surface together with air from the suction port body 6 and the like. After that, the dust-containing air is sucked into the dust collecting unit 12 from the suction port 11, and the dust is separated and collected in the dust collecting unit 12. The air from which the dust is separated is sucked into the electric blower 13, cooled, and then discharged from the exhaust port of the electric blower 13 to the outside of the vacuum cleaner main body 2 through the exhaust port.

電気掃除機１を収納する際には、図４に示すように、掃除機本体２を、前側を上方に向けて立たせ、風路体３を掃除機本体２に係止保持する。 When the vacuum cleaner 1 is housed, as shown in FIG. 4, the vacuum cleaner main body 2 is made to stand with the front side facing upward, and the air passage body 3 is locked and held by the vacuum cleaner main body 2.

まず、掃除機本体２を立たせると、図３(a)に示すように、旋回輪17は、車輪21の重量によって、車輪21が下側に位置する状態となる。風路体３を掃除機本体２に係止する際には、延長管５を捻ってホース体４を巻き付け、吸込口体６を、床面を滑らせながら掃除機本体２側に引き寄せた後、風路体３の被係止部９を、掃除機本体２の付属品係止部26に上方から下方に向けて挿入する。 First, when the vacuum cleaner main body 2 is stood up, as shown in FIG. 3A, the turning wheel 17 is in a state where the wheel 21 is positioned on the lower side due to the weight of the wheel 21. When locking the air passage body 3 to the vacuum cleaner body 2, twist the extension pipe 5 to wind the hose body 4, and then pull the suction port body 6 toward the vacuum cleaner body 2 while sliding the floor surface. , The locked portion 9 of the air passage body 3 is inserted into the accessory locking portion 26 of the vacuum cleaner main body 2 from above to below.

このとき、被係止部９を取付面24に押し当てつつ旋回輪17の上方から下方へと移動させると、カバー部19の側面部20に対して被係止部９が当接し、図３(b)に示すように旋回輪17が旋回することによって、側面部20に沿って被係止部９がガイドされるとともに、旋回輪17の周辺から付属品係止部26に亘る付属品ガイド部30に沿って被係止部９が旋回輪17の接線方向にガイドされ、取付面24に対して段差なく連なる規制面28に沿って、図３(c)に示すように、被係止部９がそのまま付属品係止部26へと容易に挿入される。図１(b)に示すように、付属品係止部26に挿入された被係止部９は、係止片部27と規制面28との間に保持され、風路体３が掃除機本体２に係止された状態を維持する。また、図３(c)に示すように、旋回輪17は、被係止部９が付属品係止部26に挿入された後、車輪21の重量によって、車輪21が下側に位置する位置に復帰するように旋回する。ホース体４は、延長管５から取り外して延長管５にさらに巻き付けて収納してもよい。 At this time, when the locked portion 9 is moved from the upper side to the lower side of the swivel wheel 17 while being pressed against the mounting surface 24, the locked portion 9 comes into contact with the side surface portion 20 of the cover portion 19 and the locked portion 9 comes into contact with FIG. By turning the swivel wheel 17 as shown in (b), the locked portion 9 is guided along the side surface portion 20, and the accessory guide extending from the periphery of the swivel wheel 17 to the accessory locking portion 26. The locked portion 9 is guided in the tangential direction of the swivel wheel 17 along the portion 30, and is locked along the regulation surface 28 which is continuously connected to the mounting surface 24 without a step, as shown in FIG. 3 (c). The portion 9 is easily inserted into the accessory locking portion 26 as it is. As shown in FIG. 1 (b), the locked portion 9 inserted into the accessory locking portion 26 is held between the locking piece portion 27 and the regulation surface 28, and the air passage body 3 is a vacuum cleaner. The state of being locked to the main body 2 is maintained. Further, as shown in FIG. 3 (c), in the swivel wheel 17, after the locked portion 9 is inserted into the accessory locking portion 26, the wheel 21 is positioned on the lower side due to the weight of the wheel 21. Turn to return to. The hose body 4 may be removed from the extension tube 5 and further wound around the extension tube 5 for storage.

以上説明した第１の実施形態によれば、掃除機本体２の旋回輪17の周辺と付属品係止部26の規制面28とが段差なく連なっているため、風路体３を付属品係止部26に係止する際に、旋回輪17の周辺から付属品係止部26に向かって風路体３の被係止部９を引っ掛かりなく規制面28に沿って滑らせて付属品係止部26に挿入することができ、付属品係止部26に対して風路体３を容易に係止できる。 According to the first embodiment described above, since the periphery of the swivel wheel 17 of the vacuum cleaner main body 2 and the regulation surface 28 of the accessory locking portion 26 are connected without a step, the air passage body 3 is attached to the accessory section. When locking to the stop portion 26, the locked portion 9 of the air passage body 3 is slid along the regulation surface 28 from the periphery of the swivel wheel 17 toward the accessory locking portion 26 to engage with the accessory. It can be inserted into the stop portion 26, and the air passage body 3 can be easily locked to the accessory locking portion 26.

また、付属品係止部26が旋回輪17の側面部20の接線上に配置されているため、旋回輪17の接線方向に沿って風路体３を移動させることで付属品係止部26に容易に係止できる。 Further, since the accessory locking portion 26 is arranged on the tangential line of the side surface portion 20 of the turning wheel 17, the accessory locking portion 26 is moved by moving the air passage body 3 along the tangential direction of the turning wheel 17. Can be easily locked.

さらに、旋回輪17の側面部20が付属品係止部26へと風路体３をガイドするガイド部となっているため、風路体３を旋回輪17の側面部20に接触させつつ付属品係止部26に向かい移動させることで、付属品係止部26に対して風路体３を容易かつ確実に係止できる。 Further, since the side surface portion 20 of the swivel wheel 17 serves as a guide portion for guiding the air passage body 3 to the accessory locking portion 26, the air passage body 3 is attached while being in contact with the side surface portion 20 of the swivel wheel 17. By moving toward the product locking portion 26, the air passage body 3 can be easily and reliably locked to the accessory locking portion 26.

しかも、旋回輪17は、付属品係止部26へと風路体３をガイドする際に風路体３と接触し、風路体３の移動に伴って旋回するため、旋回輪17の旋回によって風路体３の被係止部９を付属品係止部26に向かい円滑に、かつ、位置精度よく移動させることができる。 Moreover, since the turning wheel 17 comes into contact with the air passage body 3 when guiding the air passage body 3 to the accessory locking portion 26 and turns as the air passage body 3 moves, the turning wheel 17 turns. The locked portion 9 of the air passage body 3 can be smoothly and accurately moved toward the accessory locking portion 26.

また、旋回輪17の周辺から付属品係止部26に連なる付属品ガイド部30によって付属品係止部26へと風路体３をガイドすることで、風路体３をより容易に、かつ、位置精度よく付属品係止部26に向かって移動させることができる。 Further, by guiding the air passage body 3 from the periphery of the swivel wheel 17 to the accessory locking portion 26 by the accessory guide portion 30 connected to the accessory locking portion 26, the air passage body 3 can be made easier and more easily. , It can be moved toward the accessory locking portion 26 with high positional accuracy.

次に、第２の実施形態について図６を参照して説明する。なお、上記第１の実施形態と同様の構成および作用については、同一符号を付してその説明を省略する。 (Second embodiment)
Next, the second embodiment will be described with reference to FIG. The same components and operations as those of the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

本実施形態では、掃除機本体２の旋回輪17の周辺に対して付属品係止部26の規制面28が凹段差状に連なって形成されている。規制面28は、旋回輪17の周辺に延びる取付面24に対して窪んで形成されている。規制面28は、取付面24に対して１段のみ窪んでいてもよいし、多段窪んでいてもよいし、傾斜面でもよい。 In the present embodiment, the regulation surface 28 of the accessory locking portion 26 is formed so as to be continuous in a concave step shape with respect to the periphery of the swivel wheel 17 of the vacuum cleaner main body 2. The regulation surface 28 is formed so as to be recessed with respect to the mounting surface 24 extending around the swivel wheel 17. The regulation surface 28 may be recessed by only one step with respect to the mounting surface 24, may be recessed by multiple steps, or may be an inclined surface.

電気掃除機１を収納する際には、掃除機本体２を、前側を上方に向けて立たせた状態で、風路体３の被係止部９を、掃除機本体２の付属品係止部26に上方から下方に向けて挿入する。このとき、被係止部９を取付面24に押し当てつつ旋回輪17の上方から下方へと移動させると、カバー部19の側面部20や付属品ガイド部30に沿って被係止部９がガイドされつつ、取付面24から凹段差状に連なる規制面28に沿って被係止部９が付属品係止部26へと容易に挿入される。 When the vacuum cleaner 1 is stored, the locked portion 9 of the air passage body 3 is locked with the accessory locking portion of the vacuum cleaner main body 2 with the vacuum cleaner main body 2 standing upright with the front side facing upward. Insert into 26 from top to bottom. At this time, when the locked portion 9 is moved from above to below the swivel wheel 17 while being pressed against the mounting surface 24, the locked portion 9 is moved along the side surface portion 20 of the cover portion 19 and the accessory guide portion 30. The locked portion 9 is easily inserted into the accessory locking portion 26 along the regulation surface 28 that is continuous from the mounting surface 24 in a concave step shape.

このように、第２の実施形態によれば、風路体３を付属品係止部26に係止する際に、旋回輪17の周辺から付属品係止部26に向かって風路体３の被係止部９を滑らせると、旋回輪17の周辺から規制面28に移る際に段差はあるものの、この段差が凹段差状であるため、風路体３の被係止部９が段差に引っ掛かって移動が阻害されることはなく、風路体３の被係止部９を、旋回輪17の周辺と規制面28との段差部分を超えて規制面28に沿って滑らせて付属品係止部26に挿入することができ、付属品係止部26に対して風路体３を容易に係止でき、また、コンパクト化を図ることができる。 As described above, according to the second embodiment, when the air passage body 3 is locked to the accessory locking portion 26, the air passage body 3 is directed from the periphery of the swivel wheel 17 toward the accessory locking portion 26. When the locked portion 9 of the air passage body 3 is slid, there is a step when moving from the periphery of the swivel wheel 17 to the regulation surface 28, but since this step is a concave step, the locked portion 9 of the air passage body 3 becomes The movement is not hindered by being caught by the step, and the locked portion 9 of the air passage body 3 is slid along the regulation surface 28 beyond the step portion between the periphery of the turning wheel 17 and the regulation surface 28. It can be inserted into the accessory locking portion 26, the air passage body 3 can be easily locked to the accessory locking portion 26, and the size can be reduced.

なお、上記各実施形態において、付属品を風路体３としたが、その他、例えばつる口等の吸込口体等、任意の付属品を付属品係止部26に係止する構成としてもよい。 In each of the above embodiments, the accessory is the air passage body 3, but other accessories such as a suction port such as a vine mouth may be locked to the accessory locking portion 26. ..
