本発明は,電動送風機の運転によって塵埃を収集する電気掃除機に関し,特に,掃除機本体部の移動操作を簡単に行うことのできる電気掃除機に関するものである。   The present invention relates to a vacuum cleaner that collects dust by operation of an electric blower, and more particularly to a vacuum cleaner that can easily perform a moving operation of a vacuum cleaner main body.

ここに,図7は,従来の電気掃除機Yの一例を示す図である。なお,図7における左方向が電気掃除機Yの前方,右方向が後方であるとする。
図7に示すように,電気掃除機Yは,電動送風機や集塵室などが設けられた掃除機本体部101と,該掃除機本体部101に接続された接続ホース102と,該接続ホース102に接続された接続管103と,前記接続管103の一端に設けられた操作ハンドル部104及び他端に設けられた吸気口部105とを備えて概略構成されている。ここで,前記接続ホース102は,曲折自在であって伸縮性を有する材料で形成され,前記接続管103は,伸縮性を有しない材料で形成されている。
また,前記掃除機本体部101は,後端部の両側に設けられた一対の後輪106及び前端部の中央に設けられた補助輪107によって移動自在に支持されている。なお,例えば特許文献1(図2参照)に,図7に示す前記電気掃除機Yと同様の電気掃除機が示されている。

ここで,ユーザが前記操作ハンドル部104を操作して前記吸気口部105を移動させることのできる範囲は,前記接続管103及び前記接続ホース102の長さに限定される。そのため,その範囲を超えて清掃を行う場合,ユーザは,前記掃除機本体部101を移動させる必要がある。このとき,ユーザは,前記掃除機本体部1の場所まで移動してかがんだ状態で該掃除機本体部1を移動させるのではなく,前記接続ホース102を引っ張ることにより前記掃除機本体部101を引き寄せることが多い。
特開2000−166835号公報
FIG. 7 is a diagram illustrating an example of a conventional electric vacuum cleaner Y. In addition, suppose that the left direction in FIG. 7 is the front of the vacuum cleaner Y, and the right direction is back.
As shown in FIG. 7, the electric vacuum cleaner Y includes a vacuum cleaner main body 101 provided with an electric blower, a dust collection chamber, and the like, a connection hose 102 connected to the vacuum cleaner main body 101, and the connection hose 102. The connection pipe 103 is connected to the connection pipe 103, the operation handle part 104 is provided at one end of the connection pipe 103, and the intake port part 105 is provided at the other end. Here, the connection hose 102 is made of a material that is bendable and stretchable, and the connection tube 103 is made of a material that does not have stretchability.
The vacuum cleaner main body 101 is movably supported by a pair of rear wheels 106 provided on both sides of the rear end portion and an auxiliary wheel 107 provided in the center of the front end portion. For example, Patent Document 1 (see FIG. 2) shows a vacuum cleaner similar to the vacuum cleaner Y shown in FIG.
The user operates the vacuum cleaner Y and operates the operation handle portion 104 to move the intake port portion 105 back and forth, thereby allowing dust on the floor surface to pass through the connection pipe 103 and the connection hose 102. Dust is collected in a dust collection chamber (not shown) in the vacuum cleaner main body 101.
Here, the range in which the user can move the intake port portion 105 by operating the operation handle portion 104 is limited to the lengths of the connection pipe 103 and the connection hose 102. Therefore, when cleaning is performed beyond the range, the user needs to move the cleaner main body 101. At this time, the user does not move the vacuum cleaner main body 1 in a state where the vacuum cleaner main body 1 is moved and bent, but pulls the connection hose 102 to move the vacuum cleaner main body 101. Often attracted.
JP 2000-166835 A

しかしながら,前記接続ホース102が伸縮性を有する材料で形成されているため,該接続ホース102を引っ張って前記掃除機本体部101を所望の位置に移動させるという操作は困難である。例えば,前記掃除機本体部101が最大静止摩擦力の高い絨毯の上にある場合には,該掃除機本体部101を移動させるために大きな力が必要となるが,ユーザが大きな力で前記接続ホース102を引っ張ると,その力で動き始めた前記掃除機本体部101が所望の位置よりも行き過ぎてしまうことがある。
また,通常,ユーザは,前記掃除機本体部101よりも高い位置から前記接続ホース102を通じて該掃除機本体部101を引っ張る。そのため,前記掃除機本体部101を移動させるためには,該掃除機本体部101を水平方向から引っ張って移動させる場合に必要な力N101に,垂直方向の力N102を加えた力N103が必要となり,ユーザの負担が大きいという問題もある。
したがって,本発明は上記事情に鑑みてなされたものであり,その目的とするところは,電気掃除機の掃除機本体部の移動操作を簡単に行うことのできる電気掃除機を提供することにある。
However, since the connection hose 102 is formed of a stretchable material, it is difficult to pull the connection hose 102 and move the cleaner body 101 to a desired position. For example, when the cleaner body 101 is on a carpet having a maximum static frictional force, a large force is required to move the cleaner body 101. When the hose 102 is pulled, the cleaner body 101 that starts to move with the force may go too far from a desired position.
In general, the user pulls the cleaner body 101 from the position higher than the cleaner body 101 through the connection hose 102. Therefore, in order to move the cleaner body 101, a force N103 obtained by adding a force N102 in the vertical direction to the force N101 necessary for moving the cleaner body 101 by pulling it from the horizontal direction is required. There is also a problem that the burden on the user is large.
Accordingly, the present invention has been made in view of the above circumstances, and an object of the present invention is to provide a vacuum cleaner that can easily perform a moving operation of the vacuum cleaner main body. .

上記目的を達成するために本発明は,吸気口から塵埃を吸い込むための送風機が設けられた掃除機本体部と,前記吸気口を有する吸気口部に接続された接続管と,前記接続管及び前記掃除機本体部を接続する接続ホースと,前記掃除機本体部を移動可能に支持する車輪部と,を備えてなる電気掃除機に適用されるものであって,前記掃除機本体部の前部に接続されて該掃除機本体部から上方に長尺状を成し,該掃除機本体部を移動させるための操作に用いられる本体操作把手を備えてなり,前記車輪部が,前記掃除機本体部の後部の両側に設けられた一対の後輪を含んでなることを特徴とする電気掃除機として構成される。
このように構成された前記電気掃除機では,ユーザは,従来のように前記接続ホースを引っ張ることなく,前記本体操作把手を操作することで前記掃除機本体部を簡単に移動させて清掃を行うことができる。しかも,ユーザは,前記掃除機本体部が前記後輪だけで支持された状態で,且つその重心が前記後輪の床面への接触位置よりも前後のいずれかにずれた位置となるように,前記本体操作把手を用いて前記掃除機本体部の前方を上方に持ち上げるという操作を行うことが可能である。これにより,前記掃除機本体部の荷重により床面に対して作用する垂直方向の力が低減されるため,前記車輪部と床面との最大静止摩擦係数が小さくなり,該掃除機本体部を移動させやすくなる。
To achieve the above object, the present invention provides a vacuum cleaner main body provided with a blower for sucking dust from an air inlet, a connecting pipe connected to the air inlet having the air inlet, the connecting pipe, The present invention is applied to an electric vacuum cleaner comprising a connection hose for connecting the vacuum cleaner main body and a wheel portion for movably supporting the vacuum cleaner main body, and the front of the vacuum cleaner main body A main body operation handle that is connected to a vacuum cleaner and has an elongated shape upward from the vacuum cleaner main body, and is used for moving the vacuum cleaner main body, and the wheel portion includes the vacuum cleaner It is comprised as a vacuum cleaner characterized by including a pair of rear wheel provided in the both sides of the rear part of a main-body part.
In the electric vacuum cleaner configured as described above, the user performs cleaning by simply moving the main body of the vacuum cleaner by operating the main body operation handle without pulling the connection hose as in the prior art. be able to. In addition, the user is in a state where the vacuum cleaner main body is supported only by the rear wheel, and the center of gravity of the vacuum cleaner is shifted to the front or back of the position where the rear wheel is in contact with the floor surface. The main body operation handle can be used to perform an operation of lifting the front of the cleaner main body upward. As a result, the vertical force acting on the floor surface due to the load of the cleaner body is reduced, so that the maximum coefficient of static friction between the wheel portion and the floor is reduced, and the cleaner body is It becomes easy to move.

ところで,前記本体操作把手の適切な長さは,ユーザによって異なる。そこで,前記本体操作把手の長さを調整するための長さ調整手段を更に備えてなることが望ましい。
具体的には,前記本体操作把手が,一方が他方に挿入可能な第1の把手管及び第2の把手管を備えてなり,前記長さ調整手段が,前記第1の把手管及び前記第2の把手管の一方の他方への挿入量を調整するためのものであることが考えられる。これにより,ユーザは,前記長さ調整手段を用いて,前記第1の把手管及び前記第2の把手管の一方の他方への挿入量を調整することにより,前記本体操作把手の長さを任意に調整することができる。
By the way, the appropriate length of the main body operation handle differs depending on the user. Therefore, it is desirable to further include a length adjusting means for adjusting the length of the main body operation handle.
Specifically, the main body operation handle includes a first handle tube and a second handle tube, one of which can be inserted into the other, and the length adjusting means includes the first handle tube and the first handle tube. It is conceivable that it is for adjusting the amount of insertion of one of the two handle tubes into the other. Thereby, the user adjusts the length of the main body operation handle by adjusting the insertion amount of the first handle tube and the second handle tube into the other using the length adjusting means. It can be adjusted arbitrarily.

また,前記本体操作把手の前記掃除機本体部に対する角度を調整するための角度調整手段を更に備えてなる構成が好ましい。
具体的には,前記角度調整手段が,前記本体操作把手を前記掃除機本体部に回動自在に接続する回動接続部と,該回動接続部における前記本体操作把手の回動の可否を切り換える回動可否切換部とを含んでなることが考えられる。
このように,前記本体操作把手の前記掃除機本体部に対する角度の調整が可能であれば,即ち前記本体操作把手の傾きと前記掃除機本体部の傾きとを独立して調整することができれば,前記本体操作把手のユーザ側の端部の位置を変えることなく,前記掃除機本体部を傾ける角度を調整することが可能となる。
Moreover, the structure further provided with the angle adjustment means for adjusting the angle with respect to the said cleaner main-body part of the said main body operation handle is preferable.
Specifically, the angle adjusting means determines whether or not the main body operation handle can be rotated at the rotation connection portion for rotatably connecting the main body operation handle to the main body of the cleaner. It is conceivable to include a rotation enable / disable switching unit for switching.
As described above, if the angle of the main body operation handle with respect to the main body of the cleaner is adjustable, that is, if the inclination of the main body operation handle and the inclination of the main body of the vacuum cleaner can be adjusted independently, The angle at which the cleaner body is tilted can be adjusted without changing the position of the end of the body operation handle on the user side.

さらに,前記本体操作把手が一箇所又は複数箇所で曲折可能であって,前記掃除機本体部に,一箇所又は複数箇所で曲折された前記本体操作把手をその状態で固定する把手固定部を設けておくことが望ましい。
これにより,前記本体操作把手を用いない場合には,該本体操作把手を曲折させた状態で前記掃除機本体部に固定して収容しておくことができる。
また,前記接続ホースが,前記掃除機本体部内に挿脱可能である構成が望ましい。これにより,前記電気掃除機の未使用時などに,前記接続ホースを前記掃除機本体部に挿入して収納することができ,該電気掃除機全体の収容スペースを縮小することができる。
具体的には,前記接続ホースの前記掃除機本体部に対する挿脱の可否を切り換える挿脱切換手段を備える構成が考えられる。これにより,前記接続ホースを前記掃除機本体部に収納した状態や,前記接続ホースを前記掃除機本体部から最も引き出した状態などで,該接続ホースの前記掃除機本体部への挿脱を禁止して固定することができる。
Further, the main body operation handle can be bent at one place or a plurality of places, and the vacuum cleaner main body is provided with a handle fixing portion for fixing the main body operation handle bent at one or a plurality of places in that state. It is desirable to keep it.
Thereby, when not using the said main body operation handle, it can fix and accommodate in the said vacuum cleaner main-body part in the state which bent this main body operation handle.
Further, it is desirable that the connection hose can be inserted into and removed from the cleaner body. Thereby, when the vacuum cleaner is not used, the connection hose can be inserted and stored in the vacuum cleaner main body, and the storage space of the entire vacuum cleaner can be reduced.
Specifically, the structure provided with the insertion / extraction switching means which switches the insertion / removal of the said connection hose with respect to the said vacuum cleaner main-body part can be considered. As a result, the connection hose is prohibited from being inserted into and removed from the cleaner body in a state in which the connection hose is housed in the cleaner body or in a state in which the connection hose is most pulled out from the cleaner body. And can be fixed.

また,前記掃除機本体部の後端から後方に突出し,該掃除機本体部が略直立されたときに床面と接触することにより,前記後輪と共に前記掃除機本体部を支持する後端支持部を更に備えてなり,その後端支持部が折り畳み可能であることが望ましい。
これにより,ユーザは,前記後端支持部を折り畳むことで,前記掃除機本体部を直立よりも後方に傾けることが可能となる。即ち,前記掃除機本体部の重心が少なくとも前記後輪の床面への接触位置よりも後方に位置する状態を実現することができる。このような状態では,前記掃除機本体部から前記後輪に対して前斜め方向の力が作用することになるため,ユーザは前記掃除機本体部の前方への移動操作を容易に行うことができる。
ところで,前記電気掃除機では,前記吸気口の床面への密接度合いによって該吸気口からの吸気量が変化し,清掃性能に影響することが知られている。具体的には,前記吸気口部を押して前方へ移動させるときよりも,該吸気口部を引いて後方へ移動させるときの方が,前記吸気口からの吸気量が多く,高い清掃性能を得ることができる。
そこで,前記掃除機本体部の重心が少なくとも前記後輪の床面への接触位置よりも後方に位置する状態で,該掃除機本体部の下面を前記接続管に連結する本体連結手段を設けておくことが望ましい。このような構成では,ユーザは,前記本体操作把手を用いて前記掃除機本体部を移動させて,該掃除機本体部に連結された前記接続管を移動させることによって清掃を行うことができる。このとき,前記掃除機本体部を前進させるための力は,前記後輪に作用することになり,前記吸気口部には直接作用しないため,該吸気口部が床面に押さえつけられることがなく,前記掃除機本体部を先進させるだけで高い清掃性能を得ることができる。したがって,前記掃除機本体部を前後に揺動させながら前進させる必要がないため清掃効率を向上させることができる。
Also, a rear end support that protrudes rearward from the rear end of the cleaner body and supports the cleaner body together with the rear wheel by contacting the floor when the cleaner body is substantially upright. It is preferable that the rear end support portion is foldable.
Thereby, the user can tilt the vacuum cleaner main body part backward rather than upright by folding the rear end support part. That is, it is possible to realize a state in which the center of gravity of the vacuum cleaner main body is located at the rear of at least the contact position of the rear wheel with the floor surface. In such a state, since a force in a front oblique direction acts on the rear wheel from the cleaner body, the user can easily move the cleaner body forward. it can.
By the way, in the said vacuum cleaner, it is known that the amount of intake air from the air inlet varies depending on the closeness of the air inlet to the floor surface, which affects the cleaning performance. Specifically, the amount of intake air from the intake port is larger and the cleaning performance is higher when the intake port portion is pulled and moved backward than when the intake port portion is pushed and moved forward. be able to.
Accordingly, there is provided main body connecting means for connecting the lower surface of the cleaner main body to the connecting pipe in a state where the center of gravity of the cleaner main body is located at least rearward of the position where the rear wheel contacts the floor surface. It is desirable to keep it. In such a configuration, the user can perform cleaning by moving the cleaner body using the body operation handle and moving the connecting pipe connected to the cleaner body. At this time, the force for advancing the vacuum cleaner main body acts on the rear wheel and does not act directly on the air intake port, so that the air intake port is not pressed against the floor surface. , High cleaning performance can be obtained simply by advancing the cleaner body. Therefore, since it is not necessary to move forward while swinging the cleaner main body part back and forth, the cleaning efficiency can be improved.

本発明によれば,ユーザは,従来のように前記接続ホースを引っ張ることなく,前記本体操作把手を操作することで前記掃除機本体部を簡単に移動させて清掃を行うことができる。しかも,前記掃除機本体部の荷重により床面に対して作用する垂直方向の力を低減させることにより,前記車輪部と床面との最大静止摩擦係数を低下させて,該掃除機本体部を移動させやすくすることが可能である。   According to the present invention, the user can perform cleaning by easily moving the vacuum cleaner main body by operating the main body operation handle without pulling the connection hose as in the prior art. In addition, by reducing the vertical force acting on the floor surface due to the load of the vacuum cleaner body, the maximum static friction coefficient between the wheel portion and the floor is reduced, and the vacuum cleaner body is It is possible to make it easy to move.

以下添付図面を参照しながら,本発明の実施の形態について説明し,本発明の理解に供する。尚,以下の実施の形態は,本発明を具体化した一例であって,本発明の技術的範囲を限定する性格のものではない。

まず,図1を用いて,本発明の実施の形態に係る電気掃除機Xの概略構成について説明する。なお,図1における左方向が電気掃除機Xの前側,右方向が電気掃除機Xの後側とする。
図1に示すように,前記電気掃除機Xは,掃除機本体部1,吸気口部2,接続管3,接続ホース4,操作ハンドル5及び本体ハンドル6などを備えている。前記掃除機本体部1は,該掃除機本体部1の前端に接続された前記接続ホース4と,該接続ホース4に接続された前記接続管3とを介して前記吸気口部2に接続されている。また,前記掃除機本体部1には,前記吸気口部2が有する吸気口2aから塵埃を吸い込むための電動送風機(図4参照)や吸い込まれた塵埃が収納される集塵室12(図4参照)などが設けられている。
ユーザは,前記電気掃除機Xを稼働させ,前記操作ハンドル5を把持して操作することにより,前記接続管3を移動させて前記吸気口部2を床面上で移動させることでその床面上の清掃を行う。
具体的に,前記電気掃除機Xでは,前記掃除機本体部1に内蔵された電動送風機11(図4参照)が作動することによって,前記接続管3及び前記接続ホース4を通じて,前記吸気口部2に形成された吸気口2aからの吸気が行われる。これにより,前記吸気口部2が移動する床面上の塵埃は,該吸気口部2の吸気口2aから吸い込まれ,前記掃除機本体部1に内蔵された集塵室12(図4参照)に収集される。なお,前記電動送風機11(図4参照)によって吸い込まれた塵埃を含む空気は,前記集塵室12(図4参照)で塵埃が除去された後,排気フィルタ13(図4参照)を経て前記掃除機本体部1の後方から排出される。
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings so that the present invention can be understood. The following embodiment is an example embodying the present invention, and does not limit the technical scope of the present invention.
FIG. 1 is an external view of the vacuum cleaner X according to the embodiment of the present invention. FIG. 2 is a schematic diagram for explaining a length adjusting mechanism and a bending mechanism of the main body handle 6 of the vacuum cleaner X. FIG. 3 is a view for explaining a housing form when the main body handle 6 of the electric vacuum cleaner X is not used, FIG. 4 is an internal configuration diagram of the main body 1 of the electric vacuum cleaner X, and FIG. The figure which shows the state which accommodated the connection hose 4 of the cleaner X in the cleaner main-body part 1, FIG. 6 is a figure for demonstrating the usage example of the said vacuum cleaner X. FIG.
First, the schematic configuration of the electric vacuum cleaner X according to the embodiment of the present invention will be described with reference to FIG. 1, the left direction is the front side of the vacuum cleaner X, and the right direction is the rear side of the vacuum cleaner X.
As shown in FIG. 1, the electric vacuum cleaner X includes a vacuum cleaner main body portion 1, an intake port portion 2, a connection pipe 3, a connection hose 4, an operation handle 5, a main body handle 6, and the like. The cleaner body 1 is connected to the intake port 2 via the connection hose 4 connected to the front end of the cleaner body 1 and the connection pipe 3 connected to the connection hose 4. ing. The vacuum cleaner main body 1 has an electric blower (see FIG. 4) for sucking dust from the air inlet 2a of the air inlet 2 and a dust collecting chamber 12 (FIG. 4) for storing the sucked dust. For example).
The user operates the electric vacuum cleaner X, grasps and operates the operation handle 5, moves the connection pipe 3, and moves the intake port portion 2 on the floor surface to thereby move the floor surface. Clean up.
Specifically, in the vacuum cleaner X, when the electric blower 11 (see FIG. 4) built in the vacuum cleaner main body 1 is operated, the intake port portion is connected through the connection pipe 3 and the connection hose 4. 2. Intake from the intake port 2a formed in 2 is performed. As a result, dust on the floor on which the air inlet 2 moves is sucked from the air inlet 2a of the air inlet 2 and the dust collecting chamber 12 built in the cleaner body 1 (see FIG. 4). To be collected. The air containing dust sucked in by the electric blower 11 (see FIG. 4) is removed from the dust collection chamber 12 (see FIG. 4) and then passed through the exhaust filter 13 (see FIG. 4). It is discharged from the rear of the vacuum cleaner body 1.

また,前記掃除機本体部1は,後端部の両側に設けられた回転自在の一対の後輪71と,前端部の中央に設けられた回転自在の一つの補助輪72とを有している。通常,前記掃除機本体部1は,一対の前記後輪71及び前記補助輪72の三点で移動自在に支持される。ここに,前記後輪71及び前記補助輪72が車輪部の一例である。
また,前記掃除機本体部1の後端部には,折り畳み可能な後端支持部73が設けられている。前記後端支持部73は,前記掃除機本体部1の後端から後方に突出して設けられ,該掃除機本体部1が前記後輪71だけで支持された状態で後方に倒されて略直立するときに床面と接触することによって,前記後輪71と共に前記掃除機本体部1を支持するものである。但し,前記後端支持部73が折り畳まれている状態では,前記掃除機本体部1が前記後輪71だけで支持された状態で後方に倒されても,該後端支持部73が床面に接触せず,該掃除機本体部1は直立状態よりも後方に倒れた状態となる。
The vacuum cleaner main body 1 has a pair of rotatable rear wheels 71 provided on both sides of the rear end portion, and a rotatable auxiliary wheel 72 provided in the center of the front end portion. Yes. Usually, the cleaner body 1 is supported by three points of the pair of the rear wheel 71 and the auxiliary wheel 72 so as to be movable. Here, the rear wheel 71 and the auxiliary wheel 72 are an example of a wheel portion.
Further, a foldable rear end support portion 73 is provided at the rear end portion of the cleaner body 1. The rear end support portion 73 is provided so as to protrude rearward from the rear end of the cleaner body 1, and is substantially upright when the cleaner body 1 is tilted backward while being supported only by the rear wheel 71. The vacuum cleaner main body 1 is supported together with the rear wheel 71 by making contact with the floor surface. However, in the state in which the rear end support portion 73 is folded, the rear end support portion 73 remains on the floor surface even if the vacuum cleaner main body portion 1 is supported only by the rear wheel 71 and tilted backward. The vacuum cleaner main body 1 falls to the rear rather than the upright state.

ところで,前記接続管3は,一方が他方に挿入可能な二つの管部材を有しており,長さ調整が可能である。この接続管3は,伸縮性を有しない材料で形成されている。なお,前記接続管3には,前記補助輪72と係合することにより,該接続管3及び前記掃除機本体部1を連結する本体連結部31(本体連結手段の一例)が設けられているが,この点については後段で詳述する。
これに対し,前記接続ホース4は,曲折自在で,且つある程度の伸縮性を有する材料で形成されたものである。そして,前述したように,従来,ユーザは,その伸縮性のある前記接続ホース4を引っ張ることで前記掃除機本体部1を移動させることが多かった。しかし,それでは前記掃除機本体部1を所望の位置で停止させることができない等の問題があった。
一方,本発明の実施の形態に係る前記電気掃除機Xでは,前記掃除機本体部1の前部に,該掃除機本体部1から上方に長尺状を成し,該掃除機本体部1を移動させるための操作に用いられる本体ハンドル6(本体操作把手の一例)が設けられている。
By the way, the connecting pipe 3 has two pipe members, one of which can be inserted into the other, and the length can be adjusted. The connecting pipe 3 is formed of a material that does not have elasticity. The connecting pipe 3 is provided with a main body connecting portion 31 (an example of a main body connecting means) for connecting the connecting pipe 3 and the cleaner main body 1 by engaging with the auxiliary wheel 72. However, this point will be described in detail later.
On the other hand, the connecting hose 4 is formed of a material that is bendable and has a certain degree of elasticity. As described above, conventionally, the user often moves the cleaner body 1 by pulling the stretchable connection hose 4. However, there is a problem that the vacuum cleaner main body 1 cannot be stopped at a desired position.
On the other hand, in the electric vacuum cleaner X according to the embodiment of the present invention, the front portion of the vacuum cleaner main body 1 has a long shape upward from the vacuum cleaner main body 1, and the vacuum cleaner main body 1 A main body handle 6 (an example of a main body operation handle) used for an operation for moving the main body is provided.

図1に示すように,前記本体ハンドル部6は,前記掃除機本体部1の前端部近傍において,該掃除機本体部1の両側面の二箇所に接続されている。
ここで,前記本体ハンドル6は,前記掃除機本体部1に回動可能に支持されており,前記掃除機本体部1に対する角度を調整することが可能である。具体的には,前記掃除機本体部1に,前記本体ハンドル6の回動軸部6aを該掃除機本体部1に回動自在に接続する不図示の軸受部(回動接続部の一例)と,前記軸受部における本体ハンドル6の回動の可否を切り換える不図示の回動可否切換部(角度調整手段の一例)とが設けられている。なお,この機構は,後述する前記本体ハンドル6の曲折機構と同様に構成されたものであってもよい。このように構成された前記電気掃除機Xでは,前記本体ハンドル6の前記掃除機本体部1に対する角度を,ユーザの好みに合わせて調整することができる。
As shown in FIG. 1, the main body handle portion 6 is connected to two locations on both side surfaces of the cleaner body 1 in the vicinity of the front end portion of the cleaner body 1.
Here, the main body handle 6 is rotatably supported by the cleaner body 1 so that the angle with respect to the cleaner body 1 can be adjusted. Specifically, a bearing portion (not shown) that connects the rotary shaft portion 6a of the main body handle 6 to the cleaner main body 1 so as to be rotatable to the cleaner main body 1 (an example of a rotary connection portion). And a rotation enable / disable switching unit (an example of an angle adjusting means) (not shown) that switches whether the main body handle 6 can rotate in the bearing portion. This mechanism may be configured similarly to a bending mechanism of the main body handle 6 described later. In the electric vacuum cleaner X configured as described above, the angle of the main body handle 6 with respect to the main body 1 of the vacuum cleaner can be adjusted according to the user's preference.

そして,前記本体ハンドル6が設けられた前記電気掃除機Xでは,ユーザは,従来のように前記接続ホース4を引っ張ることなく,前記本体ハンドル6を用いて前記掃除機本体部1を簡単に所望の位置に移動させることができる。
特に,前記掃除機本体部1では,前記本体ハンドル6が前記掃除機本体部1の前端部近傍に接続されているため,図1に示すように,前記掃除機本体部1が前記後輪71だけで支持された状態で,且つその重心が前記後輪71の床面への接触位置よりも前にずれた位置となるように,前記本体ハンドル6を用いて前記掃除機本体部1の前方を上方に持ち上げるという操作を行うことが可能である。このとき,前記掃除機本体部1の前記後輪71に対する荷重N1は,図1に示すように,垂直方向の力N2と水平方向の力N3に分力される。
したがって,前記後輪71から床面に対して作用する垂直方向の力が低減されるため,前記後輪71と床面との最大静止摩擦係数が小さくなり,該掃除機本体部1を移動させやすくなる。
In the electric vacuum cleaner X provided with the main body handle 6, the user simply desires the cleaner main body 1 using the main body handle 6 without pulling the connection hose 4 as in the prior art. It can be moved to the position.
In particular, in the cleaner main body 1, the main body handle 6 is connected to the vicinity of the front end of the cleaner main body 1, so that the cleaner main body 1 is connected to the rear wheel 71 as shown in FIG. 1. The main body handle 6 is used to move the front of the vacuum cleaner main body 1 so that the center of gravity is shifted forward from the contact position of the rear wheel 71 with the floor surface. It is possible to perform an operation of lifting up. At this time, the load N1 applied to the rear wheel 71 of the cleaner body 1 is divided into a vertical force N2 and a horizontal force N3 as shown in FIG.
Accordingly, since the vertical force acting on the floor surface from the rear wheel 71 is reduced, the maximum static friction coefficient between the rear wheel 71 and the floor surface is reduced, and the cleaner body 1 is moved. It becomes easy.

次に,図2及び図3を用いて,前記本体ハンドル6の詳細について説明する。
図2(a)に示すように,前記本体ハンドル6は,前記掃除機本体部1に接続される本体接続部61と,前記本体接続部61に接続された中継部62(第1の把手管の一例)と,前記中継部62に挿脱可能な把持部63(第2の把手管の一例)とを有している。
まず,図2(a),(b)を参照しつつ,前記本体ハンドル6の長さ調整機構について説明する。なお,ここで説明する長さ調整機構は単なる一例に過ぎず,従来周知の他の機構を用いてもよい。
前記把持部63は,前記中継部62に挿入される部位に所定間隔ごとに形成された凹部631を有している。一方,前記中継部62は,該中継部62内に突出して前記凹部631に嵌合する嵌合部621と,その嵌合部621の前記中継部62内への突出の有無を切り換える機械式の固定スイッチ622とを有している。
このように構成された前記本体ハンドル6では,前記固定スイッチ622を操作して前記嵌合部621の前記凹部631への嵌合を解除し,前記把持部63を前記中継部62に対して移動させた後,前記嵌合部621を前記凹部631に嵌合させることにより,前記把持部63の前記中継部62への挿入量を調整して,該本体ハンドル6全体の長さを調整することができる(図2(a),(b)参照)。ここに,前記凹部631,前記嵌合部621及び前記固定スイッチ622が,前記本体ハンドル6における長さ調整機構(長さ調整手段の一例)を構成する。
Next, details of the main body handle 6 will be described with reference to FIGS.
As shown in FIG. 2A, the main body handle 6 includes a main body connecting portion 61 connected to the cleaner main body portion 1 and a relay portion 62 (first handle tube) connected to the main body connecting portion 61. And a grip portion 63 (an example of a second handle tube) that can be inserted into and removed from the relay portion 62.
First, the length adjusting mechanism of the main body handle 6 will be described with reference to FIGS. 2 (a) and 2 (b). The length adjusting mechanism described here is merely an example, and other conventionally known mechanisms may be used.
The gripping part 63 has recesses 631 formed at predetermined intervals at the part inserted into the relay part 62. On the other hand, the relay part 62 is a mechanical part that switches into a fitting part 621 that protrudes into the relay part 62 and fits into the concave part 631 and whether or not the fitting part 621 projects into the relay part 62. And a fixed switch 622.
In the main body handle 6 thus configured, the fixed switch 622 is operated to release the fitting portion 621 from fitting into the concave portion 631, and the gripping portion 63 is moved with respect to the relay portion 62. Then, by fitting the fitting portion 621 into the concave portion 631, the insertion amount of the grip portion 63 into the relay portion 62 is adjusted, and the overall length of the main body handle 6 is adjusted. (See FIGS. 2A and 2B). Here, the concave portion 631, the fitting portion 621, and the fixed switch 622 constitute a length adjusting mechanism (an example of a length adjusting unit) in the main body handle 6.

続いて,図2(a),(c)を参照しつつ,前記本体ハンドル6の曲折機構について説明する。なお,ここで説明する曲折機構は単なる一例に過ぎず,従来周知の他の機構を用いてもよい。
前記本体接続部61は,前記中継部62を回動可能に支持する回動支持部611を有している。前記回動支持部611には,前記中継部62の回動を制限して固定するための固定溝612が形成されている。また,前記回動支持部611には,後述の回動軸部623の回動の可否を切り換えるための移動スペース613が設けられている。
一方,前記中継部62は,前記回動支持部611に軸支される回動軸部623を有している。前記回動軸部623の周囲には,前記固定溝612に嵌合することにより,該回動軸部623を中心とする前記中継部62の回動を制限して固定するための複数の凸部624が形成されている。
このように構成された前記本体ハンドル部6では,前記回動軸部623を前記移動スペース613に移動させて,前記固定溝612及び前記凸部624の嵌合を解除することで,前記中継部62を回動させることが可能となる(図2(c)参照)。その後,前記回動軸部623を移動させて前記固定溝612及び前記凸部624を嵌合させることにより,前記中継部62の回動を制限して固定することができる(図2(a)参照)。
このように,前記本体ハンドル6は,前記回動支持部611において曲折可能に構成されている。なお,ここでは,前記本体ハンドル6が,一箇所で曲折可能である構成について説明したが,更に複数の曲折機構を有することにより複数箇所で曲折可能な構成であってもかまわない。
Next, the bending mechanism of the main body handle 6 will be described with reference to FIGS. 2 (a) and 2 (c). The bending mechanism described here is merely an example, and other conventionally known mechanisms may be used.
The main body connecting portion 61 has a rotation support portion 611 that rotatably supports the relay portion 62. The rotation support portion 611 is formed with a fixing groove 612 for limiting and fixing the rotation of the relay portion 62. In addition, the rotation support portion 611 is provided with a moving space 613 for switching whether or not a rotation shaft portion 623 described later can be rotated.
On the other hand, the relay unit 62 includes a rotation shaft portion 623 that is pivotally supported by the rotation support portion 611. A plurality of protrusions for restricting and fixing the rotation of the relay portion 62 around the rotation shaft portion 623 by being fitted in the fixing groove 612 around the rotation shaft portion 623. A portion 624 is formed.
In the main body handle portion 6 thus configured, the relay shaft portion 623 is moved to the moving space 613 and the fitting of the fixed groove 612 and the convex portion 624 is released, thereby the relay portion. 62 can be rotated (see FIG. 2C). Thereafter, the rotation of the relay portion 62 can be restricted and fixed by moving the rotation shaft portion 623 and fitting the fixing groove 612 and the convex portion 624 (FIG. 2A). reference).
Thus, the main body handle 6 is configured to be bendable at the rotation support portion 611. In addition, although the structure which the said main body handle | steering-wheel 6 can be bent in one place was demonstrated here, the structure which can be bent in several places by having a several bending mechanism further may be sufficient.

ところで,前記本体ハンドル6を使用しない場合には,該本体ハンドル6が邪魔になる場合もある。そこで,図1に示すように,前記電気掃除機Xでは,前記掃除機本体部1の上面部に,曲折された前記本体ハンドル6をその状態で固定するハンドル固定部8(把手固定部の一例)が設けられている。前記ハンドル固定部8は,例えば前記本体ハンドル6の把持部63に嵌合或いは係合することにより,該把持部63を固定するものである。
このように前記ハンドル固定部8を有する前記電気掃除機Xでは,図3(a)に示す状態から,前記本体ハンドル6を曲折させて前記ハンドル固定部8に固定することによって,図3(b)に示すように,前記本体ハンドル6が邪魔にならないように,該掃除機本体部1に収容することができる。
By the way, when the main body handle 6 is not used, the main body handle 6 may get in the way. Therefore, as shown in FIG. 1, in the electric vacuum cleaner X, a handle fixing portion 8 (an example of a handle fixing portion) that fixes the bent main body handle 6 to the upper surface portion of the vacuum cleaner main body 1 in that state. ) Is provided. The handle fixing portion 8 fixes the grip portion 63 by fitting or engaging with the grip portion 63 of the main body handle 6, for example.
In the electric vacuum cleaner X having the handle fixing portion 8 as described above, the main body handle 6 is bent and fixed to the handle fixing portion 8 from the state shown in FIG. ), The main body handle 6 can be accommodated in the cleaner body 1 so as not to get in the way.

続いて,図4〜6を用いて,前記電気掃除機Xにおいて,前記接続ホース4が前記掃除機本体部1の内部に収納可能である点について説明する。ここに,図4は前記電気掃除機Xの掃除機本体部1の内部構成図であって,(a)は前記掃除機本体部1を側方から見た内部構成図,(b)は上方から見た内部構成図,(c)は(a)におけるA−A矢示断面図である。
図4(a),(b)に示すように,前記電気掃除機Xの前記掃除機本体部1内には,電動送風機11(ファン付きモーター),集塵室12,排気フィルタ13等の他に,前記接続ホース4を収納するための収納スペース14が設けられている。また,前記掃除機本体部1の前端部には,該掃除機本体部1内に前記接続ホース4を挿入するためのホース挿入口15が設けられている。前記接続ホース4は,前記ホース挿入口15から前記掃除機本体部1内に挿入され,前記集塵室12に接続されている。
一般に,従来の電気掃除機では,前記接続ホース4は,前記ホース挿入口15に固定されており,該接続ホース4は,前記掃除機本体部1内に対して挿脱することができない。
しかしながら,前記電気掃除機Xでは,前記接続ホース4の前記ホース挿入口15への固定の有無を切り換えることが可能な構成が採用されており,該接続ホース4を前記収納スペース14に挿入して収納することができる。
Subsequently, the point that the connection hose 4 can be stored inside the vacuum cleaner main body 1 in the electric vacuum cleaner X will be described with reference to FIGS. 4 is an internal configuration diagram of the vacuum cleaner main body 1 of the electric vacuum cleaner X, (a) is an internal configuration diagram of the vacuum cleaner main body 1 viewed from the side, and (b) is an upper view. (C) is an AA arrow cross-sectional view in (a).
As shown in FIGS. 4A and 4B, in the vacuum cleaner body 1 of the vacuum cleaner X, there are an electric blower 11 (motor with a fan), a dust collecting chamber 12, an exhaust filter 13, and the like. Further, a storage space 14 for storing the connection hose 4 is provided. Further, a hose insertion port 15 for inserting the connection hose 4 into the cleaner body 1 is provided at the front end of the cleaner body 1. The connection hose 4 is inserted into the cleaner body 1 from the hose insertion port 15 and connected to the dust collection chamber 12.
In general, in the conventional vacuum cleaner, the connection hose 4 is fixed to the hose insertion port 15, and the connection hose 4 cannot be inserted into and removed from the cleaner body 1.
However, the vacuum cleaner X employs a configuration that can switch whether the connection hose 4 is fixed to the hose insertion port 15, and the connection hose 4 is inserted into the storage space 14. Can be stored.

具体的に,前記電気掃除機Xでは,図4(c)に示すように,前記接続ホース4及び前記ホース挿入口15に,相互に係合するホース側フック41,本体側ホルダー151が設けられている。前記ホース側フック41は,前記接続ホース4を前記ホース挿入口15から外部に最も露出させたときに,該ホース挿入口15の本体側ホルダー151に係合する位置に設けられている。例えば,前記接続ホース4を回転させることにより前記ホース側フック41が前記本体側ホルダー151に係合する構成が考えられる。
このように構成された前記電気掃除機Xでは,前記ホース側フック41を前記本体側ホルダー151に係合させることにより,前記接続ホース4を前記ホース挿入口15に固定することでき,前記ホース側フック41及び前記本体側ホルダー151の係合を解除させることにより,前記接続ホース4を前記ホース挿入口15に対して挿脱することが可能となる。ここに,前記ホース側フック41及び前記本体側ホルダー151が挿脱切換手段の一例である。
したがって,例えば前記電気掃除機Xを使用しない場合には,図5(a),(b)に示すように,前記接続ホース4を前記掃除機本体部1内の収納スペース14に収納することで,該電気掃除機Xの収容に必要なスペースを縮小させることができる。また,前記接続ホース4を前記掃除機本体1に収納した状態で相互に係合する係合部を,前記操作ハンドル5及び前記ホース挿入口15に設けておくことで,該接続ホース4を前記掃除機本体1に収納した状態を保持させることができる。
Specifically, in the electric vacuum cleaner X, as shown in FIG. 4C, the connection hose 4 and the hose insertion port 15 are provided with a hose side hook 41 and a main body side holder 151 which are engaged with each other. ing. The hose side hook 41 is provided at a position where the hose insertion port 15 engages with the main body side holder 151 when the connection hose 4 is most exposed to the outside from the hose insertion port 15. For example, a configuration in which the hose side hook 41 is engaged with the main body side holder 151 by rotating the connection hose 4 is conceivable.
In the electric vacuum cleaner X thus configured, the connection hose 4 can be fixed to the hose insertion port 15 by engaging the hose side hook 41 with the main body side holder 151, and the hose side The connection hose 4 can be inserted into and removed from the hose insertion port 15 by releasing the engagement between the hook 41 and the main body side holder 151. Here, the hose side hook 41 and the main body side holder 151 are examples of insertion / removal switching means.
Therefore, for example, when the electric vacuum cleaner X is not used, the connection hose 4 is stored in the storage space 14 in the main body 1 of the vacuum cleaner as shown in FIGS. , The space required for housing the vacuum cleaner X can be reduced. In addition, the connection hose 4 can be connected to the operation hose 5 and the hose insertion port 15 by providing an engaging portion that engages the connection hose 4 in a state where the connection hose 4 is housed in the cleaner body 1. The state accommodated in the cleaner body 1 can be maintained.

その他,例えば,図6(a)に示すように,前記電気掃除機Xの清掃の対象となる床面と前記電気掃除機Xを載置する床面との高さが異なる場合には,前記接続ホース4を前記掃除機本体部1内に収容した状態で使用することで,前記接続ホース4から発せられる騒音を低減することができる。
また,前記係合部41,151に換えて,前記接続ホース4を任意の位置で,前記ホース挿入口15に固定することのできる構成も考えられる。例えば,前記ホース挿入口15に前記接続ホース4の外周部を把持/解除する把持部材を設けておくことが考えられる。これにより,前記把持部材による前記接続ホース4の把持/解除を切り換えて,前記接続ホース4の前記掃除機本体部1への挿入量を調整し,該接続ホース4の露出部の長さを任意に調整することが可能である。
In addition, for example, as shown in FIG. 6A, when the floor surface to be cleaned by the vacuum cleaner X and the floor surface on which the vacuum cleaner X is placed are different, By using the connection hose 4 in a state where the connection hose 4 is housed in the cleaner body 1, noise generated from the connection hose 4 can be reduced.
Moreover, it can replace with the said engaging parts 41 and 151, and the structure which can fix the said connection hose 4 to the said hose insertion port 15 in arbitrary positions is also considered. For example, it is conceivable to provide a gripping member for gripping / releasing the outer periphery of the connection hose 4 at the hose insertion port 15. Thereby, the grip / release of the connection hose 4 by the grip member is switched to adjust the insertion amount of the connection hose 4 into the cleaner body 1, and the length of the exposed portion of the connection hose 4 can be arbitrarily set. It is possible to adjust to.

また,前記電気掃除機Xは,図6(b)に示すように,所謂アップライト型の電気掃除機に変形させることが可能である。
具体的には,前記接続ホース4を前記掃除機本体部1内に収納した状態(図5,図6(a)参照)から,さらに前記接続管3を縮めて,該接続管3に設けられた前記本体連結部31に,前記掃除機本体部1の補助輪72を係合させることにより,該掃除機本体部1及び前記接続管3を連結することで,図6(b)に示すようにアップライト型の形態が実現される。
ここで,前記本体連結部31は,前記掃除機本体部1が前記後輪71だけで支持され,前記掃除機本体部1の重心が少なくとも前記後輪71の床面への接触位置よりも後方に位置する状態で,該掃除機本体部1の下面に設けられた前記補助輪72に係合することにより,前記掃除機本体部1及び前記接続管3を連結するものである。したがって,前記本体連結部31によって前記接続管3に連結された前記掃除機本体部1は,その重心が前記後輪71の床面への接触位置よりも後方に位置することになる。
Further, as shown in FIG. 6B, the electric vacuum cleaner X can be transformed into a so-called upright type electric vacuum cleaner.
Specifically, from the state in which the connection hose 4 is housed in the cleaner body 1 (see FIGS. 5 and 6A), the connection pipe 3 is further contracted to be provided on the connection pipe 3. As shown in FIG. 6B, the cleaner main body 1 and the connecting pipe 3 are connected by engaging the auxiliary wheel 72 of the cleaner main body 1 with the main body connecting portion 31. An upright type is realized.
Here, the main body connecting portion 31 is such that the cleaner main body 1 is supported only by the rear wheel 71, and the center of gravity of the cleaner main body 1 is behind at least the position where the rear wheel 71 contacts the floor surface. In this state, the cleaner main body 1 and the connecting pipe 3 are connected by engaging with the auxiliary wheel 72 provided on the lower surface of the cleaner main body 1. Therefore, the vacuum cleaner main body 1 connected to the connecting pipe 3 by the main body connecting portion 31 has a center of gravity located behind the position where the rear wheel 71 contacts the floor.

このように変形された前記電気掃除機Xでは,ユーザは,前記操作ハンドル5ではなく,前記本体ハンドル6を把持して前記電気掃除機X全体を移動させて,前記吸気口部2を床面上で移動させることにより,その床面上を清掃することができる。
このとき,前記掃除機本体部1の重心は,前記後輪71よりも後方に位置しているため,該掃除機本体1の荷重N1が前記後輪71に対して前斜め下方向に作用することになる。この荷重N1は,図6に示すように,垂直方向の力N2と水平方向の力N4に分力される。即ち,前記掃除機本体1が前進する方向の力N4が作用するため,ユーザによる前記電気掃除機Xの前進動作が容易となる。
さらに,従来では,ユーザは前記操作ハンドル5を用いて前記吸気口部2を前進させていたため,該吸気口部2を前進させる際に,該吸気口部2に前斜め下方向,即ち前記吸気口2aが床面に密着する方向に力が作用していた。そのため,前記吸気口部2を前進させるだけではなく,前記吸気口部2を前後に揺動させながら前進させる必要があった。
しかし,前記電気掃除機Xでは,前述したように,前記本体ハンドル6を把持して前記掃除機本体1を前進させることで,前記吸気口部2を前進させて清掃を行うことができる。そのため,前記本体ハンドル6から作用する前斜め下方向の力は前記吸気口部2に直接作用せず,前記掃除機本体1を支持する前記後輪71に作用する。したがって,前記吸気口部2の吸気口2aが床面に密着し過ぎない状態を維持しつつ前記吸気口部2を前進させることができ,前記電気掃除機Xを前進させるだけで高い清掃性能を得ることができる。
In the electric vacuum cleaner X thus deformed, the user grasps the main body handle 6 instead of the operation handle 5 and moves the entire electric vacuum cleaner X to move the intake port portion 2 to the floor surface. The floor can be cleaned by moving it up.
At this time, since the center of gravity of the cleaner body 1 is located behind the rear wheel 71, the load N <b> 1 of the cleaner body 1 acts on the rear wheel 71 obliquely downward in the front direction. It will be. As shown in FIG. 6, this load N1 is divided into a vertical force N2 and a horizontal force N4. That is, since the force N4 in the direction in which the cleaner body 1 moves forward acts, the user can easily move the vacuum cleaner X forward.
Further, conventionally, since the user has advanced the intake port portion 2 by using the operation handle 5, when the intake port portion 2 is advanced, the intake port portion 2 is moved forward obliquely downward, that is, the intake air port. A force was acting in the direction in which the mouth 2a was in close contact with the floor surface. For this reason, it is necessary not only to move the intake port portion 2 forward but also to move the intake port portion 2 forward and backward.
However, in the electric vacuum cleaner X, as described above, the main body handle 6 is grasped and the cleaner main body 1 is advanced, whereby the intake port portion 2 can be advanced to perform cleaning. Therefore, the front diagonally downward force acting from the main body handle 6 does not directly act on the intake port 2 but acts on the rear wheel 71 that supports the cleaner body 1. Therefore, the intake port 2 can be advanced while maintaining the state where the intake port 2a of the intake port 2 is not too close to the floor surface, and high cleaning performance can be achieved simply by moving the electric vacuum cleaner X forward. Obtainable.
