Description

本発明は、サイクロン式電気掃除機に関するものである。   The present invention relates to a cyclonic vacuum cleaner.

従来、この種のサイクロン式電気掃除機としては、電動送風機が内蔵された掃除機本体と、この掃除機本体に着脱自在に取り付けられるダストボックス１０１（本願発明の集塵部に相当する）とを有し、このダストボックス１０１の側壁１０２の略接線方向に気流が流入するように吸気口１０３（本願発明の導入部に相当する）を設けると共に、ダストボックスの側壁と同心円状且つ吸気口からダストボックスに流入する空気の流れ方向に前記ダストボックスの壁１０４を延設して前記吸気口の一部を閉塞したものが知られている（例えば、特許文献１参照。）。このようなサイクロン式電気掃除機は、前記壁１０４によって前記吸気口１０３の口径を連通部１０５の内径より小さくすることにより、前記ダストボックス内でのサイクロン作用を良好にすることができ、遠心力を良好にして高い集塵性能を得ることができると共に、前記ダストボックス内に溜まる塵埃の量を多くすることができて、使い勝手がよい電気掃除機を実現することができるものである。   Conventionally, this type of cyclone type vacuum cleaner has a vacuum cleaner main body with an electric blower built therein, and a dust box 101 (corresponding to the dust collecting portion of the present invention) detachably attached to the main body of the vacuum cleaner. In addition, an air inlet 103 (corresponding to the introduction portion of the present invention) is provided so that the airflow flows in a direction substantially tangential to the side wall 102 of the dust box 101, and is concentric with the side wall of the dust box and flows into the dust box from the air inlet. It is known that a wall 104 of the dust box is extended in the air flow direction and a part of the intake port is closed (see, for example, Patent Document 1). In such a cyclonic vacuum cleaner, the diameter of the air inlet 103 is made smaller than the inner diameter of the communication portion 105 by the wall 104, so that the cyclone action in the dust box can be improved, and the centrifugal force is increased. It is possible to obtain a good vacuum collecting performance while being able to obtain good dust collection performance and to increase the amount of dust accumulated in the dust box.

特許第３２９８５７３号公報Japanese Patent No. 3298573

しかしながら、このようなサイクロン式電気掃除機は、前記吸気口の口径部に前記壁を形成しなければならないため、成形金型の構造が複雑となり、コストアップを招くという問題があった。また、前記吸気口を通る気流をスムーズに前記ダストボックスの内壁に向かうように導くには、前記吸気口の流通面積が口径部に向かって徐々に小さくなるようにしなければならないが、この場合、ダストボックスに肉厚となる部分が生じるため、成形の難易度は更に向上し、更にコストアップを招くことになる。   However, such a cyclone type vacuum cleaner has a problem in that the wall of the intake port must be formed with the wall, which complicates the structure of the molding die and increases the cost. Further, in order to guide the airflow passing through the air intake port smoothly toward the inner wall of the dust box, the flow area of the air intake port must be gradually reduced toward the diameter portion. Since a thickened portion is generated, the difficulty of molding is further improved and the cost is further increased.

本発明は以上の問題点を解決し、安価にサイクロン作用を向上させることができるサイクロン式電気掃除機を提供することを目的とする。   An object of the present invention is to solve the above-mentioned problems and to provide a cyclonic vacuum cleaner that can improve the cyclone action at low cost.

本発明の請求項１に記載のサイクロン式電気掃除機は、電動送風機を有する掃除機本体と、この掃除機本体に着脱自在に取り付けられるサイクロン式集塵部とを有し、このサイクロン式集塵部が、サイクロン筒と、このサイクロン筒の内壁に沿うように気流を導入する導入部とを有するサイクロン式電気掃除機において、前記導入部に、吸引ホース部材の挿入筒部が挿入可能に構成されると共に、この挿入筒部の一端部における前記サイクロン式集塵部の中心側の壁を、前記サイクロン式集塵部の外周側に向けて屈曲させることで一端部側を狭くした屈曲部を設けたものである。 The cyclonic vacuum cleaner according to claim 1 of the present invention has a vacuum cleaner main body having an electric blower and a cyclone dust collecting portion detachably attached to the vacuum cleaner main body, and the cyclone dust collecting In the cyclone type vacuum cleaner having a cyclone cylinder and an introduction part for introducing an air flow along the inner wall of the cyclone cylinder, the insertion cylinder part of the suction hose member can be inserted into the introduction part. Rutotomoni, bending the center side of the wall of the cyclone type dust collecting part of an end portion of the insertion tube, which is narrowed at one end portion side Rukoto is bent toward the outer circumferential side of the cyclone type dust collecting part A part is provided.

また、本発明の請求項２に記載のサイクロン式電気掃除機は、請求項１において、前記挿入筒部を前記導入部に挿入した状態において、前記屈曲部の端部が、前記サイクロン筒の内壁の延長面とほぼ等しい位置となるように構成したものである。   The cyclonic vacuum cleaner according to claim 2 of the present invention is the cyclonic vacuum cleaner according to claim 1, wherein the end of the bent portion is the inner wall of the cyclone cylinder in a state where the insertion cylinder is inserted into the introduction section. It is comprised so that it may become a position substantially equal to the extended surface of.

本発明の請求項１に記載のサイクロン式電気掃除機は、以上のように構成することにより、前記吸引ホース部材を通って吸引された含塵気流が、前記導入部内に挿入された前記挿入筒を通って前記サイクロン筒内に流入し、このサイクロン筒の内壁に沿って旋回する渦流となり、遠心力によって気流に含まれる塵埃を分離することができる。そしてこの際、含塵気流が前記サイクロン筒内に流入する直前に、前記屈曲部によって含塵気流の流通面積が狭められると共に前記サイクロン筒の内壁に向けて方向付けられるので、含塵気流をほぼ全て前記サイクロン筒の内壁に沿って旋回する渦流とし、また、前記サイクロン筒内の渦流の角速度を速くして、遠心分離作用を向上させることができる。また、前記挿入筒部に屈曲部を設けたことで、前記サイクロン式集塵部自体の構造を単純にすることができるため、サイクロン式集塵部の成形が容易であると共に、前記挿入筒部の成形の難易度は単なる円筒の場合と大差ない。従って、前記サイクロン式電気掃除機の遠心分離作用を向上させつつ、安価に構成することができる。 The cyclone-type vacuum cleaner according to claim 1 of the present invention is configured as described above, whereby the dust-containing airflow sucked through the suction hose member is inserted into the introduction portion. The vortex flows into the cyclone cylinder and passes along the inner wall of the cyclone cylinder, and the dust contained in the airflow can be separated by centrifugal force. At this time, immediately before the dust-containing airflow flows into the cyclone cylinder, the flow area of the dust-containing airflow is narrowed by the bent portion and directed toward the inner wall of the cyclone cylinder. All of the vortex flow swirls along the inner wall of the cyclone cylinder, and the angular velocity of the vortex flow in the cyclone cylinder can be increased to improve the centrifugal action. Moreover, since the structure of the cyclone type dust collecting part itself can be simplified by providing the insertion cylinder part with a bent part, the cyclone type dust collection part can be easily molded, and the insertion cylinder part The difficulty of molding is not much different from that of a simple cylinder. Therefore, it can be constructed at low cost while improving the centrifugal separation action of the cyclonic vacuum cleaner.

また、前記挿入筒部を前記導入部に挿入した状態において、前記屈曲部の端部が、前記サイクロン筒の内壁の延長面とほぼ等しい位置となるように構成したことで、前記屈曲部が前記サイクロン筒内を旋回する渦流の妨げにならないので、遠心分離作用の低下を抑えることができる。   Further, in the state where the insertion tube portion is inserted into the introduction portion, the end portion of the bent portion is configured to be at a position substantially equal to the extended surface of the inner wall of the cyclone tube, so that the bent portion is Since it does not interfere with the vortex swirling in the cyclone cylinder, it is possible to suppress a decrease in the centrifugal separation effect.

以下、本発明の実施形態について、図１及び図２に基づいて説明する。１は本発明のサイクロン式電気掃除機である。このサイクロン式電気掃除機１は、掃除機本体２と、サイクロン式集塵部３と、吸引ホース部材４とを有して構成される。   Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2. 1 is a cyclonic vacuum cleaner of the present invention. The cyclone vacuum cleaner 1 includes a cleaner body 2, a cyclone dust collecting unit 3, and a suction hose member 4.

前記掃除機本体２は、その内部に電動送風機５を有する。また、前記掃除機本体２は、被清掃面上を自由に移動できるように、車輪６を有する。また、前記掃除機本体２は、その上面に、前記電動送風機５を作動させるためのスイッチ操作部７を有する。また、前記掃除機本体２は、その上面に、先端にプラグ８が設けられた図示しない電源コードを巻き取るためのコード巻き取り操作部９を有する。また、前記掃除機本体２は、その上面に、この掃除機本体を把持して持ち運ぶための把持部１０を有する。また、前記掃除機本体２は、その上面に、前記サイクロン式集塵部３を着脱自在に固定するためのフック１１を有する。更に、前記掃除機本体２は、その後部に排気口部１２を有する。   The cleaner body 2 has an electric blower 5 inside. Moreover, the said vacuum cleaner main body 2 has the wheel 6 so that it can move freely on the to-be-cleaned surface. Moreover, the said cleaner body 2 has the switch operation part 7 for operating the said electric blower 5 on the upper surface. Moreover, the said cleaner body 2 has the cord winding operation part 9 for winding up the power cord which is not illustrated in which the plug 8 was provided in the front-end | tip at the upper surface. Moreover, the said vacuum cleaner main body 2 has the holding part 10 for holding and carrying this vacuum cleaner main body on the upper surface. Moreover, the said vacuum cleaner main body 2 has the hook 11 for detachably fixing the said cyclone type dust collecting part 3 to the upper surface. Further, the cleaner body 2 has an exhaust port 12 at the rear part thereof.

前記サイクロン式集塵部３は、前記掃除機本体２に対して着脱自在に取り付けられる。そして、前記サイクロン式集塵部３は、サイクロン筒１３と、このサイクロン筒１３と一体に設けられた導入部１４と、この導入部１４に固定された取付部１５と、前記サイクロン筒１３の中央に設けられた出口部１６とを有する。前記取付部１５には、前記吸引ホース部材４の挿入筒部１７が挿入される。そして、この挿入筒部１７は、前記取付部１５に対して取り付けられる。なお、前記挿入筒部１７の一端部１７Ａは、前記導入部１４内に達すると共に、前記サイクロン筒１３の内壁１３Ａの延長面とほぼ等しい位置となる。また、前記出口部１６は、前記サイクロン式集塵部３を掃除機本体２に取り付けた際に、前記電動送風機５と連通する。   The cyclonic dust collector 3 is detachably attached to the cleaner body 2. The cyclone dust collecting unit 3 includes a cyclone cylinder 13, an introduction part 14 provided integrally with the cyclone cylinder 13, an attachment part 15 fixed to the introduction part 14, and a center of the cyclone cylinder 13. And an outlet portion 16 provided in the main body. An insertion tube portion 17 of the suction hose member 4 is inserted into the attachment portion 15. The insertion tube portion 17 is attached to the attachment portion 15. One end portion 17A of the insertion tube portion 17 reaches the inside of the introduction portion 14 and is at a position substantially equal to the extended surface of the inner wall 13A of the cyclone tube 13. Further, the outlet portion 16 communicates with the electric blower 5 when the cyclone type dust collecting portion 3 is attached to the cleaner body 2.

また、前記挿入筒部１７を前記導入部１４に挿入した際に前記サイクロン集塵部３の中心側となる前記挿入筒部１７の一端部１７Ａの壁を、前記サイクロン式集塵部３の外周側に向けてスムーズに屈曲させることで、屈曲部１７Ｂが形成される。なお、前記挿入筒部１７は、前記屈曲部１７Ｂが前記サイクロン式集塵部３の中心側（図２における下側）となるように、挿入方向が規制される。また、前記挿入筒部１７の他端部には、図示しない屈曲ホース及び吸引ノズル等が設けられる。   Further, when the insertion cylinder part 17 is inserted into the introduction part 14, the wall of the one end part 17 </ b> A of the insertion cylinder part 17 that becomes the center side of the cyclone dust collection part 3 is used as the outer periphery of the cyclone dust collection part 3. The bent portion 17B is formed by smoothly bending toward the side. The insertion direction of the insertion tube portion 17 is regulated so that the bent portion 17B is on the center side (lower side in FIG. 2) of the cyclone type dust collection portion 3. In addition, a bending hose and a suction nozzle (not shown) are provided at the other end of the insertion tube portion 17.

このように、前記サイクロン式集塵部３の導入部１４を単なる筒状に形成することができるので、サイクロン式集塵部３自体の構造を単純にすることができる。従って、前記サイクロン式集塵部３を成形するための成形金型の構造も単純化することができるので、前記サイクロン式集塵部３を容易に且つ安価に製造することができる。一方、前記挿入筒部１７の成形の難易度は、成形金型の形状が違うだけで、単なる筒状のものを成形する場合と大差ない。従って、サイクロン式電気掃除機１を、容易且つ安価に製造することができる。   Thus, since the introduction part 14 of the cyclone type dust collecting part 3 can be formed in a simple cylinder shape, the structure of the cyclone type dust collecting part 3 itself can be simplified. Therefore, the structure of the molding die for molding the cyclone type dust collecting part 3 can be simplified, so that the cyclone type dust collecting part 3 can be manufactured easily and inexpensively. On the other hand, the degree of difficulty in forming the insertion cylinder portion 17 is not much different from that in the case of forming a simple cylindrical one, except that the shape of the molding die is different. Therefore, the cyclonic vacuum cleaner 1 can be manufactured easily and inexpensively.

次に、本実施形態の作用について説明する。まず使用者は、図示しないコードリールから前記コードを引き出し、前記プラグ８を図示しない交流電源に接続する。また、前記サイクロン式集塵部３を前記掃除機本体２に取り付けると共に、前記ホース部材４の挿入筒部１７を、前記サイクロン式集塵部３の取付部１５に挿入し、取り付ける。そして、前記スイッチ操作部７を操作することで、前記電動送風機５を作動させる。このように、前記電動送風機５が作動すると、含塵気流が、前記ホース部材４を通って前記サイクロン式集塵部３に流入する。そして、このサイクロン式集塵部３で、気流から塵埃が分離される。また、塵埃が分離された気流は、前記サイクロン式集塵部３の出口部１６から前記電動送風機５に至り、更に、前記排気口部１２から大気中に放出される。   Next, the operation of this embodiment will be described. First, the user pulls out the cord from a cord reel (not shown) and connects the plug 8 to an AC power source (not shown). Further, the cyclone type dust collecting part 3 is attached to the cleaner body 2, and the insertion cylinder part 17 of the hose member 4 is inserted and attached to the attachment part 15 of the cyclone type dust collecting part 3. And the said electric blower 5 is operated by operating the said switch operation part 7. FIG. As described above, when the electric blower 5 is operated, the dust-containing airflow flows into the cyclone type dust collecting section 3 through the hose member 4. The cyclone type dust collecting unit 3 separates dust from the air current. The air stream from which the dust has been separated reaches the electric blower 5 from the outlet 16 of the cyclone type dust collector 3 and is further discharged from the exhaust port 12 into the atmosphere.

前記サイクロン式集塵部３及びその周辺における気流について詳述する。前記ホース部材４を通った含塵気流は、前記挿入筒部１７を通って前記サイクロン筒１３に流入する。この際、含塵気流のうち、図２の状態で前記サイクロン集塵部３の外周側となる前記挿入筒部１７の一端部１７Ａの壁（図２における前記挿入筒部１７の上壁）に沿って流れる含塵気流は、前記サイクロン筒１３の内壁１３Ａに沿うように前記サイクロン筒１３内に流入する。一方、含塵気流のうち、図２の状態で前記サイクロン集塵部３の中心側となる前記挿入筒部１７の一端部１７Ａの壁（図２における前記挿入筒部１７の下壁）に沿って流れる含塵気流は、前記屈曲部１７Ｂによって前記サイクロン筒１３の内壁１３Ａに向かうように方向付けられる。これによって、前記挿入筒部１７を通って前記サイクロン筒１３内に流入する含塵気流は、前記サイクロン筒１３の外周側を通るように方向付けられる。このため、前記挿入筒部１７から前記サイクロン筒１３内に流入した含塵気流は、ほぼ全て前記サイクロン筒１３の内壁１３Ａに沿って旋回する渦流となり、前記出口部１６から直接流出することが殆どない。   The airflow in the cyclone type dust collecting part 3 and its periphery will be described in detail. The dust-containing airflow passing through the hose member 4 flows into the cyclone cylinder 13 through the insertion cylinder portion 17. At this time, in the dust-containing airflow, on the wall of the one end portion 17A of the insertion tube portion 17 which is the outer peripheral side of the cyclone dust collecting portion 3 in the state of FIG. 2 (the upper wall of the insertion tube portion 17 in FIG. 2). The dust-containing airflow flowing along the cylinder flows into the cyclone cylinder 13 along the inner wall 13A of the cyclone cylinder 13. On the other hand, along the wall of one end portion 17A of the insertion tube portion 17 that is the center side of the cyclone dust collecting portion 3 in the state of FIG. 2 in the dust-containing airflow (the lower wall of the insertion tube portion 17 in FIG. 2). The dust-containing airflow flowing in the direction is directed toward the inner wall 13A of the cyclone cylinder 13 by the bent portion 17B. As a result, the dust-containing airflow that flows into the cyclone cylinder 13 through the insertion cylinder portion 17 is directed to pass through the outer peripheral side of the cyclone cylinder 13. For this reason, almost all of the dust-containing airflow that has flowed into the cyclone cylinder 13 from the insertion cylinder portion 17 becomes a swirl that swirls along the inner wall 13A of the cyclone cylinder 13 and flows out directly from the outlet portion 16. Absent.

また、前記挿入筒部１７の一端部１７Ａ側が狭くなっていることで、前記サイクロン筒１３に流入する気流の流速は、前記挿入筒部１７を通過する気流の流速よりも速い。従って、前記サイクロン筒１３内の渦流の角速度を速くすることができるので、その分、気流中に含まれる塵埃に働く遠心力を大きくすることができ、遠心分離作用を高めることができる。 Further, since the one end portion 17 </ b> A side of the insertion tube portion 17 is narrowed, the flow velocity of the airflow flowing into the cyclone tube 13 is faster than the flow velocity of the airflow passing through the insertion tube portion 17. Therefore, since the angular velocity of the vortex flow in the cyclone cylinder 13 can be increased, the centrifugal force acting on the dust contained in the airflow can be increased correspondingly, and the centrifugal action can be enhanced.

なお、前述したように、前記挿入筒部１７の一端部１７Ａが、前記サイクロン筒１３の内壁１３Ａの延長面とほぼ等しい位置となることで、前記挿入筒部１７の一端部１７Ａが前記サイクロン筒１３内の渦流を殆ど妨げないので、渦流による遠心分離作用の低下を抑えることができる。なお、前記挿入筒部１７の一端部１７Ａが前記サイクロン筒１３内に突出すると、この突出部分によって渦流が妨げられ、遠心分離作用が低下する虞がある。逆に、前記挿入筒部１７の一端部１７Ａが前記サイクロン筒１３から引っ込んだ位置にあると、前記サイクロン筒１３の内壁１３Ａと前記挿入筒部１７の一端部１７Ａとの間で乱流が発生することになり、遠心分離作用が低下する虞がある。 As described above, the one end portion 17A of the insertion tube portion 17 is positioned substantially equal to the extended surface of the inner wall 13A of the cyclone tube 13, so that the one end portion 17A of the insertion tube portion 17 is the cyclone tube. Since the eddy current in 13 is hardly obstructed, it is possible to suppress a decrease in the centrifugal action due to the eddy current . If the one end portion 17A of the insertion tube portion 17 protrudes into the cyclone tube 13, vortex flow is prevented by this protruding portion, and the centrifugal separation action may be reduced. Conversely, when one end 17A of the insertion cylinder 17 is in a position retracted from the cyclone cylinder 13, a turbulent flow is generated between the inner wall 13A of the cyclone cylinder 13 and the one end 17A of the insertion cylinder 17. As a result, the centrifugal separation action may be reduced.

以上のように本発明は、電動送風機５を有する掃除機本体２と、この掃除機本体２に着脱自在に取り付けられるサイクロン式集塵部３とを有し、このサイクロン式集塵部３が、サイクロン筒１３と、このサイクロン筒１３の内壁１３Ａに沿うように気流を導入する導入部１４とを有するサイクロン式電気掃除機１であり、吸引ホース部材４の挿入筒部１７が前記導入部１４に挿入可能に構成されると共に、前記挿入筒部１７の一端部１７Ａにおける前記サイクロン式集塵部３の中心側の壁を、前記サイクロン式集塵部３の外周側に向けて屈曲させた屈曲部１７Ｂを設けたことで、単純で且つ安価な構成でありながら、渦流が前記サイクロン筒１３の外周側を通り且つ渦流の角速度を速くすることができるので、遠心分離作用を向上させることができるものである。 As described above, the present invention includes the vacuum cleaner body 2 having the electric blower 5 and the cyclone dust collection unit 3 that is detachably attached to the vacuum cleaner body 2, and the cyclone dust collection unit 3 is The cyclone electric vacuum cleaner 1 includes a cyclone cylinder 13 and an introduction part 14 for introducing an air flow along the inner wall 13A of the cyclone cylinder 13, and an insertion cylinder part 17 of the suction hose member 4 is connected to the introduction part 14. A bent portion configured to be insertable and having a wall on the center side of the cyclonic dust collecting portion 3 at one end portion 17A of the insertion cylinder portion 17 bent toward the outer peripheral side of the cyclonic dust collecting portion 3 by providing the 17B, while being simple and inexpensive construction, it is possible vortex to increase the angular velocity of the street and swirl the outer peripheral side of the cyclone tube 13, to improve the centrifugal separation effect It is those that can be.

また、前記挿入筒部１７を前記導入部１４に挿入した状態において、前記屈曲部１７Ｂの端部、即ち前記一端部１７Ａが、前記サイクロン筒１３の内壁１３Ａの延長面とほぼ等しい位置となるように構成したことで、前記屈曲部１７Ｂが前記サイクロン筒１３内を旋回する渦流の妨げにならないので、遠心分離作用の低下を抑えることができる。   Further, in a state where the insertion tube portion 17 is inserted into the introduction portion 14, the end portion of the bent portion 17 </ b> B, that is, the one end portion 17 </ b> A is positioned substantially equal to the extended surface of the inner wall 13 </ b> A of the cyclone tube 13. By being configured in this manner, the bent portion 17B does not hinder the vortex flow swirling in the cyclone cylinder 13, so that the reduction in the centrifugal separation action can be suppressed.

なお、本発明は以上の実施形態に限定されるものではなく、発明の要旨の範囲内で種々の変形実施が可能となる。例えば、上記実施形態では、サイクロン式集塵部の軸方向を水平としたが、サイクロン式集塵部の軸方向が垂直となる場合であっても、作用は同じである。   In addition, this invention is not limited to the above embodiment, A various deformation | transformation implementation is possible within the range of the summary of invention. For example, in the above embodiment, the axial direction of the cyclone type dust collecting part is horizontal, but the operation is the same even when the axial direction of the cyclone type dust collecting part is vertical.
