Japanese Patent No. 2627275 JP-A-4-364822

従来技術において、前記電気掃除機本体を前記支持体に収納した状態でスティック型の掃除機として使用する場合、例えば机やテーブル等が置いてある床を掃除する際に、机やテーブル等の下に前記ノズルヘッドを差し込み、このノズルヘッドを床に沿って移動させて掃除をしようとすると、机やテーブル等に前記掃除機の前部が衝突してしまい、この衝撃によって前記電気掃除機本体と支持体の位置関係がずれて気流漏れが発生したり、場合によっては前記電気掃除機本体が前記支持体から脱落してしまったりする虞があった。また、衝突時の衝撃によって前記集塵部等に亀裂が生じると、この亀裂によって気流漏れが発生する虞もあった。また、衝突時の衝撃によって、前記電気掃除機本体内の電動送風機が損傷してしまう虞もあった。更に、このような電気掃除機は、後方に傾けて使用する際に、床面に沿って前方に押し出すばかりでなく、床面に沿って後方に引き寄せる場合もあるので、電気掃除機の後方を障害物に衝突させてしまう虞があり、また、衝突時の衝撃等によって前記把持部から手が離れ、電気掃除機を床面に落としてしまう虞があり、このような衝突や落下による衝撃によって、前記電気掃除機本体と支持体の位置関係がずれてシール不良が発生したり、前記電気掃除機本体が前記支持体から脱落したり、前記集塵部や電動送風機が損傷したりする虞もあった。   In the prior art, when the vacuum cleaner body is used as a stick-type vacuum cleaner while being stored in the support, for example, when cleaning a floor on which a desk or table is placed, If the nozzle head is inserted into the nozzle and the nozzle head is moved along the floor for cleaning, the front part of the vacuum cleaner collides with a desk or table, etc. There is a possibility that the positional relationship of the support is shifted and airflow leakage occurs, or in some cases, the main body of the vacuum cleaner falls off the support. In addition, when a crack occurs in the dust collecting part or the like due to an impact at the time of a collision, there is a possibility that an airflow leak occurs due to the crack. In addition, the electric blower in the electric vacuum cleaner body may be damaged due to the impact at the time of collision. Furthermore, when using such a vacuum cleaner tilted backward, it may not only push forward along the floor surface, but may also pull backward along the floor surface. There is a risk of collision with an obstacle, and there is a risk that the hand will be released from the gripping part due to impact at the time of collision, etc., and the vacuum cleaner may be dropped on the floor surface. There is also a risk that the positional relationship between the main body of the vacuum cleaner and the support is shifted and a sealing failure occurs, the main body of the vacuum cleaner falls off from the support, or the dust collecting part or the electric blower is damaged. there were.

一方、前記電気掃除機本体を単独で使用して、例えば机やテーブル等の天板上に沿って前記電気掃除機本体を移動させて掃除をしようとすると、天板上の電気スタンド等に前記電気掃除機本体が衝突してしまい、この衝撃によって、前記集塵部や電動送風機が損傷する虞もあった。   On the other hand, when the vacuum cleaner body is used alone, for example, when the vacuum cleaner body is moved along a top plate such as a desk or a table, and the cleaning is performed, The vacuum cleaner body collided, and there was a possibility that the dust collecting part and the electric blower were damaged by this impact.

このような衝撃に伴う問題点を解決するには、保護手段を、第一に、使用状態における前記電気掃除機本体の前部に設けること、第二に、前記支持体の後部に設けることが考えられる。   In order to solve the problems associated with such an impact, firstly, a protective means is provided at the front part of the main body of the vacuum cleaner in use, and secondly, it is provided at the rear part of the support body. Conceivable.

This is the difference between the total weight of the support and the main body of the vacuum cleaner and the weight of the main body of the vacuum cleaner, and the obstacle placed on the floor was placed on a top plate such as a desk or table This is because the weight tends to be larger than the obstacle. Therefore, the front part of the main body of the vacuum cleaner attached to the front part of the support body is provided with a protection means for anticipating the collision shock in the state of being attached to the support body, not the collision shock when used alone. As a result, the main body of the vacuum cleaner, which should be small, increases in size, and there is a possibility that the usability when using the main body of the vacuum cleaner alone may be reduced.

Further, in the support 3, the storage portion 2 is formed in a concave shape on the rear side near one end of the support body 24. The support body 24 as a whole is formed in a bow shape with the front surface protruding slightly forward. The storage portion 2 is formed so as to appear on the rear side of the support 3, and the storage portion 2 includes the first pipe-shaped portion 15 and the second pipe-shaped portion 19 connected to the first pipe-shaped portion 15. It is formed in a state where both the rear, upper and left and right sides except the front and lower sides of the storage part 2 are opened so that the electric vacuum cleaner main body 1 can be stored in a state in which it faces backward. Further, a mounting receiver 29 on which one end of the electric vacuum cleaner main body 1 can be mounted is provided below the storage unit 2, and the mounting receiver 29 includes the universal joint 27. A connection port 30 on the secondary side is provided upward. The first suction port 11 is connected to the connection port 30 in an airtight manner so as to be able to communicate with the connection port 30, and the first pipe-shaped portion 15 is provided around the rear side of the connection port 30. A first fitting receiving portion 31 that can be fitted to the left and right sides and the rear portion around the suction port 11 is U-shaped in a plan view and protrudes upward. On the other hand, in the upper part of the storage part 2, the part corresponding to the rear connection part 17 when the electric vacuum cleaner main body 1 is stored, in the embodiment, in the vicinity of the connection part between the rear connection part 17 and the grip part 18. A pair of left and right second fitting receiving portions 32 that can be fixed by sandwiching the portion from the left and right are provided at corresponding portions.

なお、前記ノズルヘッド２６は、平面視が略Ｔ字状であると共に偏平な箱型のヘッドケース３３の下面前部に、前記横長吸込口２５が左右方向に長く開口して設けられており、前記自在継ぎ手２７に連通している。そして、前記横長吸込口２５から接続口３０までの間に第二吸気路３４が形成される。   The nozzle head 26 has a substantially T-shape in plan view and is provided with the horizontally long suction port 25 long open in the left-right direction at the lower front portion of a flat box-shaped head case 33. It communicates with the universal joint 27. A second intake path 34 is formed between the horizontally long suction port 25 and the connection port 30.

以上の構成を有する電気掃除機において、机やテーブルの天板上等の被清掃面Ｇを掃除するために、前記支持体３から前記電気掃除機本体１を分離して、この電気掃除機本体１を使用する場合、使用者は、前記機枠ケース４の他端部に設けられた前記第一把持部１１の握り部１８を握って前記電気掃除機本体１を持つ。そして、使用者が前記スイッチ２０を操作することで、前記充電池９からの電力によって前記電動送風器８が作動してそのファン７が回転し、これによって、前記第一吸込口１１から第一パイプ状部材１５を通って吸入されて、前記集塵部５及び前記電動送風器８を通過し、図示しない前記排気路を経て前記機枠ケース４外に排出される吸込気流が発生する。このように、前記電動送風器８が作動した状態で前記第一吸込口１１を被清掃面Ｇに近付け、この被清掃面Ｇに沿って前記第一吸込口１１が動くように前記電気掃除機本体１を移動させることで、塵埃を含んだ吸込気流が前記第一吸込口１１から吸い込まれ、そして、この塵埃を含んだ吸込気流が前記第一吸気路１２を構成する前記第一パイプ状部１５から前記導入口１４を経て前記集塵部５の容器５Ａ内に流入する。   In the vacuum cleaner having the above configuration, the vacuum cleaner body 1 is separated from the support 3 in order to clean the surface G to be cleaned such as on the top of a desk or table, and the vacuum cleaner body. When using 1, the user holds the electric vacuum cleaner main body 1 by grasping the grip 18 of the first grip 11 provided at the other end of the machine casing 4. Then, when the user operates the switch 20, the electric blower 8 is activated by the electric power from the rechargeable battery 9, and the fan 7 is rotated. A suction airflow is generated which is sucked through the pipe-shaped member 15, passes through the dust collection unit 5 and the electric blower 8, and is discharged out of the machine casing 4 through the exhaust path (not shown). Thus, the electric vacuum cleaner 8 is moved so that the first suction port 11 is brought close to the surface to be cleaned G and the first suction port 11 moves along the surface to be cleaned G in a state where the electric blower 8 is activated. By moving the main body 1, the suction airflow including dust is sucked from the first suction port 11, and the suction airflow including dust constitutes the first pipe-like portion constituting the first intake passage 12. 15 flows into the container 5 </ b> A of the dust collector 5 through the inlet 14.

そして、前記導入口１４から前記集塵部５の容器５Ａ内に入り込んだ塵埃を含む気流は、前記渦流発生手段１３の気流案内部１３Ａによって、前記容器５Ａの内面の接線方向に方向付けられることで、この容器５Ａの内周面に沿って旋回する渦流となると共に、前記容器５Ａ内を螺旋状に下降する。この際、この渦流に含まれる前記塵埃のうち、少なくとも粗い塵埃は、遠心力によって前記集塵部５の容器５Ａの内周面に押し付けられることで、前記渦流から分離されることになる。そして、遠心力によって粗い塵埃が分離された気流は、前記渦流発生手段１３の中央に設けられた前記フィルタ２２を通過する。そして、前記気流が前記フィルタ２２を通過する際、前記気流に含まれている遠心力では分離されなかった細かい塵埃が濾過される。更に、前記フィルタ２２によって塵埃が取り除かれた気流は、前記排気路２３を経て前記集塵部５から排出され、前記電動送風機８に吸い込まれる。そして、このようにして気流から分離された塵埃は、前記集塵部５の容器５Ａ内に溜められる。この際、図１の使用時において、前記導入口１４が前記集塵部５の容器５Ａに対して上方に配置されることで、この容器５Ａに溜まった塵埃が自重で前記導入口１４から前記第一吸込口１１に逆戻りすることはない。また、前記容器５Ａ内に溜められた塵埃は、前記集塵部５を前記機枠ケース４より取り外すと共に、前記渦流発生手段１３を前記容器５Ａ内から取り外して、前記容器５Ａの上部開口部を開放させることで、廃棄することができる。   Then, the air flow including the dust that has entered the container 5A of the dust collecting unit 5 from the introduction port 14 is directed in the tangential direction of the inner surface of the container 5A by the air flow guiding unit 13A of the vortex generating means 13. Thus, the vortex flow swirls along the inner peripheral surface of the container 5A and descends spirally in the container 5A. At this time, at least coarse dust out of the dust contained in the vortex is separated from the vortex by being pressed against the inner peripheral surface of the container 5A of the dust collecting unit 5 by centrifugal force. The airflow from which coarse dust is separated by centrifugal force passes through the filter 22 provided in the center of the eddy current generating means 13. And when the said airflow passes the said filter 22, the fine dust which was not isolate | separated with the centrifugal force contained in the said airflow is filtered. Further, the airflow from which the dust has been removed by the filter 22 is discharged from the dust collecting unit 5 through the exhaust passage 23 and sucked into the electric blower 8. The dust separated from the airflow in this way is stored in the container 5A of the dust collecting unit 5. At this time, when the inlet 14 is used, the inlet 14 is disposed above the container 5A of the dust collecting portion 5 so that the dust accumulated in the container 5A is self-weighted from the inlet 14 to the container 5A. There is no return to the first inlet 11. The dust collected in the container 5A is removed from the machine casing 4 and the eddy current generating means 13 is removed from the container 5A to open the upper opening of the container 5A. It can be discarded by opening it.

このように、前記電気掃除機本体１を単独で使用して机やテーブルの天板上等の被清掃面Ｇを掃除する際、この被清掃面Ｇ上に置いてある障害物（例えばディスプレイＤ等）に前記電気掃除機本体１が衝突する虞がある。しかしながら、前記電気掃除機本体１がディスプレイＤ等の障害物に衝突したとしても、その衝突する位置は、前記第一パイプ状部１５を覆う保護手段１５Ａである。そして、前述したように、前記保護手段１５Ａと前記第一パイプ状部１５との間に僅かな空隙が形成されていることによって、衝突時の衝撃によって前記保護手段１５Ａが変形可能に構成されているので、この保護手段１５Ａの変形によって衝撃が吸収され、前記第一パイプ状部１５が受ける衝撃が緩和される。これによって、前記第一パイプ状部１５や容器５Ａ、即ち前記集塵部５が破損して気流漏れが発生する虞を減ずることができるばかりでなく、前記集塵部５が取り付けられる前記機枠ケース４内に設けられた前記電動送風器８のモータ６やファン７への衝撃に伴う故障等を減ずることができる。   Thus, when the surface to be cleaned G such as the top of a desk or table is cleaned using the electric vacuum cleaner main body 1 alone, an obstacle (for example, display D) placed on the surface to be cleaned G is used. Etc.), the vacuum cleaner body 1 may collide. However, even if the vacuum cleaner main body 1 collides with an obstacle such as the display D, the position of the collision is the protection means 15A that covers the first pipe-shaped portion 15. As described above, since a slight gap is formed between the protection means 15A and the first pipe-like portion 15, the protection means 15A is configured to be deformable by an impact at the time of collision. Therefore, the impact is absorbed by the deformation of the protection means 15A, and the impact received by the first pipe-shaped portion 15 is reduced. Accordingly, not only can the first pipe-like portion 15 and the container 5A, that is, the dust collecting portion 5 be damaged, and the risk of airflow leakage can be reduced, but also the machine frame to which the dust collecting portion 5 is attached. It is possible to reduce a failure associated with an impact on the motor 6 and the fan 7 of the electric blower 8 provided in the case 4.

一方、机やテーブルの下の床面等の被清掃面Ｆを掃除するために、前記支持体３に前記電気掃除機本体１を取り付けた状態でスティック型の掃除機として使用する場合、使用者は、前記支持体３の接続口３０に前記電気掃除機本体１の第一吸込口１１が接続されるよう、前記支持体３の収納部２に前記電気掃除機本体１を収納すると共に、前記支持体３の支持本体２４の他端側に設けられた前記第二把持部２８を持ち、前記支持本体２４の一端側に設けられた前記ノズルヘッド２６を被清掃面Ｆ上に置く。そして、使用者が前記スイッチ２０を操作することで、前記充電池９からの電力によって前記電動送風器８が作動してそのファン７が回転し、これによって、塵埃を含んだ吸込気流が第二吸込口である前記横長吸込口２５から吸い込まれ、前記ノズルヘッド２６、自在継手２７、接続口３０（即ち前記第二吸気路３４）を介して、前記第一吸込口１１から第一パイプ状部材１５（即ち前記第一吸気路１２）を通り、前記集塵部５の容器５Ａ内に流入する。そして、前記第二吸気路３４の後半（前記自在継手２７から前記接続口３０にかけて）と前記第一吸気路１２は、図２に示すように、直線的に接続されることになる。このため、吸気路が曲がっている場合に比べて圧力損失が少なく、吸込気流がスムーズに前記容器５Ａまで流れるばかりでなく、塵埃が吸気路の曲がった部分の壁に衝突して付着してしまうといった問題も起きにくい。なお、塵埃の分離及び気流の排出については前述した通りなので、説明を省略する。   On the other hand, in order to clean the surface to be cleaned F such as a floor surface under a desk or a table, when using the electric vacuum cleaner main body 1 on the support 3 as a stick type vacuum cleaner, Accommodates the vacuum cleaner main body 1 in the storage portion 2 of the support 3 so that the first suction port 11 of the vacuum cleaner main body 1 is connected to the connection port 30 of the support 3. The second holding portion 28 provided on the other end side of the support body 24 of the support 3 is held, and the nozzle head 26 provided on one end side of the support body 24 is placed on the surface F to be cleaned. Then, when the user operates the switch 20, the electric blower 8 is activated by the electric power from the rechargeable battery 9 and the fan 7 rotates, whereby the suction airflow including dust is secondly generated. The first pipe-shaped member is sucked from the horizontally long suction port 25, which is a suction port, and from the first suction port 11 through the nozzle head 26, the universal joint 27, and the connection port 30 (that is, the second intake passage 34). 15 (that is, the first intake passage 12) and flows into the container 5A of the dust collecting portion 5. The second half of the second intake passage 34 (from the universal joint 27 to the connection port 30) and the first intake passage 12 are linearly connected as shown in FIG. For this reason, there is less pressure loss than when the intake passage is bent, and not only the suction airflow flows smoothly to the container 5A, but also the dust collides with and adheres to the curved portion of the intake passage. Such problems are unlikely to occur. Since the separation of dust and the discharge of airflow are as described above, description thereof will be omitted.

このように、前記電気掃除機をスティック型として使用して床等の被清掃面Ｆを掃除する際、この被清掃面Ｆ上に置いてある障害物（例えば机やテーブルの天板Ｔ等）に前記電気掃除機が衝突する虞がある。しかしながら、前記電気掃除機が机やテーブルの天板Ｔ等の障害物に衝突したとしても、その衝突する位置は、中空の前記支持本体２４である。そして、前述したように、前記支持本体２４が中空に構成されていることによって、衝突時の衝撃によって前記支持本体２４が変形可能に構成されているので、この支持本体２４の変形によって衝撃が吸収され、前記支持体３に取り付けられた前記電気掃除機本体１が受ける衝撃が緩和される。これによって、前記支持体３に取り付けられた前記電気掃除機本体１の機枠ケース４内に設けられた前記電動送風器８のモータ６やファン７への衝撃に伴う故障等を減ずることができる。   In this way, when the surface to be cleaned F such as a floor is cleaned using the electric vacuum cleaner as a stick type, an obstacle placed on the surface F to be cleaned (for example, a table top T of a desk or table). There is a risk that the vacuum cleaner will collide. However, even if the vacuum cleaner collides with an obstacle such as a tabletop or a table top T, the collision position is the hollow support body 24. As described above, since the support body 24 is configured to be hollow, the support body 24 is configured to be deformable by an impact at the time of collision. Therefore, the impact is absorbed by the deformation of the support body 24. Thus, the impact received by the main body 1 attached to the support 3 is alleviated. As a result, it is possible to reduce a failure associated with an impact on the motor 6 or the fan 7 of the electric blower 8 provided in the machine casing 4 of the electric vacuum cleaner main body 1 attached to the support 3. .

また、前記支持体３に前記電気掃除機本体１を取り付けた状態で掃除する場合、前記電気掃除機を被清掃面Ｆに沿って後方に引き寄せる際に、電気掃除機の後方を障害物に衝突させてしまう虞があるばかりでなく、前記第二把持部２８から手が離れてしまうことで前記電気掃除機が倒れ、この電気掃除機の後方が床Ｆに衝突してしまう虞もある。しかしながら、このような場合、後ろ向きに取り付けられている前記第一パイプ状部１５を覆う前記保護手段１５Ａが床Ｆに衝突すると共に、前述したように、前記保護手段１５Ａと前記第一パイプ状部１５との間に僅かな空隙が形成されていることによって、衝突時の衝撃によって前記保護手段１５Ａが変形可能に構成されているので、この保護手段１５Ａの変形によって衝撃が吸収され、前記第一パイプ状部１５が受ける衝撃が緩和される。これによって、前記第一パイプ状部１５や容器５Ａ、即ち前記集塵部５が破損して気流漏れが発生する虞を減ずることができるばかりでなく、前記集塵部５が取り付けられる前記機枠ケース４内に設けられた前記電動送風器８のモータ６やファン７への衝撃に伴う故障等を減ずることができる。   Further, when cleaning with the vacuum cleaner body 1 attached to the support 3, the rear of the vacuum cleaner collides with an obstacle when the vacuum cleaner is pulled rearward along the surface F to be cleaned. There is a risk that the electric vacuum cleaner will fall when the hand is separated from the second grip portion 28 and the rear of the electric vacuum cleaner may collide with the floor F. However, in such a case, the protective means 15A covering the first pipe-shaped portion 15 attached rearward collides with the floor F, and as described above, the protective means 15A and the first pipe-shaped portion 15 15 is formed so that the protection means 15A can be deformed by an impact at the time of collision. Therefore, the impact is absorbed by the deformation of the protection means 15A, and the first The impact received by the pipe-like portion 15 is reduced. Accordingly, not only can the first pipe-like portion 15 and the container 5A, that is, the dust collecting portion 5 be damaged, and the risk of airflow leakage can be reduced, but also the machine frame to which the dust collecting portion 5 is attached. It is possible to reduce a failure associated with an impact on the motor 6 and the fan 7 of the electric blower 8 provided in the case 4.

なお、前記支持体３に前記電気掃除機本体１を取り付けた状態でスティック型掃除機として使用する場合に、前記支持本体２４が机やテーブルの天板Ｔ等の障害物に衝突した際の衝撃は、前記電気掃除機本体１を単独で手持ち型掃除機として使用する場合に、前記保護手段１５ＡがディスプレイＤ等の障害物に衝突した際の衝撃よりも大きい。これは、前記支持体３と電気掃除機本体１の合計重量と、前記電気掃除機本体１単体の重量との相違、床等の被清掃面Ｆ上に置かれた障害物が、机やテーブルの天板等の被清掃面Ｇ上に置かれた障害物よりも重量が大きい傾向にあること、並びに、床等の被清掃面Ｆ上でスティック型の電気掃除機を動かす速さが、机やテーブルの天板等の被清掃面Ｇ上で手持ち型の電気掃除機を動かす速さよりも速い傾向にあること等にに起因する。従って、前記支持体３の支持本体２４は、スティック型の電気掃除機として使用する場合の大きな衝突衝撃を見込んだ形状や大きさに形成する必要があるものの、前記電気掃除機本体１の前部に設けられる前記保護手段１５Ａは、前記電気掃除機本体１を単独で使用する場合の比較的小さな衝突衝撃を見込んだ形状や大きさに形成すればよく、この結果、前記電気掃除機本体１の大型化を抑えることができ、この電気掃除機本体１を単独で使用する際の使い勝手を低下させないようにすることができる。   Note that when the electric vacuum cleaner main body 1 is attached to the support 3 and used as a stick-type vacuum cleaner, the impact when the support main body 24 collides with an obstacle such as a table or a table top T. Is larger than the impact when the protection means 15A collides with an obstacle such as the display D when the vacuum cleaner body 1 is used alone as a hand-held vacuum cleaner. This is because the difference between the total weight of the support 3 and the vacuum cleaner main body 1 and the weight of the vacuum cleaner main body 1 alone is that an obstacle placed on the surface to be cleaned F such as a floor is a desk or table. The weight tends to be larger than the obstacle placed on the surface to be cleaned G such as a top plate, and the speed of moving the stick type vacuum cleaner on the surface to be cleaned F such as the floor is This is because, for example, the speed tends to be higher than the speed of moving the hand-held vacuum cleaner on the surface to be cleaned G such as a table top. Accordingly, the support body 24 of the support 3 needs to be formed in a shape and size that allow for a large impact when used as a stick-type vacuum cleaner. The protection means 15A provided on the vacuum cleaner body 1 may be formed in a shape and size that allow for a relatively small impact when the vacuum cleaner body 1 is used alone. The increase in size can be suppressed, and the usability when the vacuum cleaner main body 1 is used alone can be prevented from being lowered.

また、前記支持体３に前記電気掃除機本体１を取り付けた状態でスティック型掃除機として使用する場合に、前記電気掃除機の前側となる前記支持本体２４が机やテーブルの天板Ｔ等の障害物に衝突した際の衝撃は、前記電気掃除機の後側となる前記保護手段１５Ａが障害物に衝突した際の衝撃よりも大きい傾向にある。これは、図２に示すように、前記電気掃除機が後方に倒れていることで、前記被清掃面Ｆに沿って前記電気掃除機を前方に押し出す場合、前記電気掃除機の支持本体２４が机やテーブルの天板Ｔ等の障害物に衝突した際の衝撃によって前記電気掃除機を被清掃面Ｆに押し付ける力が働き、前記天板Ｔ等と被清掃面Ｆの間で衝突時の力の逃げ場がないのに対し、前記被清掃面Ｆに沿って前記電気掃除機を後方に引き寄せる場合、前記保護手段１５Ａに衝突する虞のある障害物が、使用者と前記電気掃除機の間に存在しなければならないため、比較的低いものであることから、前記電気掃除機の保護手段１５Ａが低い障害物に衝突した際の衝撃によって前記電気掃除機を前記被清掃面Ｆから浮かす力が働き、これによって、衝突時の力を適度に逃がすことができるからである。また、前記電気掃除機の前側となる前記支持本体２４の衝突の頻度も、前記電気掃除機の後側となる前記保護手段１５Ａの衝突頻度よりも高い。これは、前述したように、前記保護手段１５Ａに障害物が衝突する場合、この障害物は、使用者と前記電気掃除機の間に存在しなければならないためである。このため、スティック型として使用される状態の電気掃除機において、この電気掃除機の後側に位置する保護手段１５Ａが、前記電気掃除機本体１を単独で使用する場合の比較的小さな衝突衝撃を見込んだ形状や大きさに形成されていたとしても、障害物との衝突による衝撃から充分に前記電気掃除機本体１を保護することができる。   When the vacuum cleaner body 1 is attached to the support 3 and used as a stick-type vacuum cleaner, the support body 24 on the front side of the vacuum cleaner is a table or table top plate T or the like. The impact when colliding with an obstacle tends to be larger than the impact when the protective means 15A on the rear side of the vacuum cleaner collides with an obstacle. This is because, as shown in FIG. 2, when the vacuum cleaner is tilted backward, when the vacuum cleaner is pushed forward along the surface F to be cleaned, the support body 24 of the vacuum cleaner is A force that presses the vacuum cleaner against the surface F to be cleaned by an impact when it collides with an obstacle such as a table top T of a desk or table works, and the force at the time of collision between the table top T and the surface F to be cleaned When the vacuum cleaner is pulled back along the surface F to be cleaned, there is an obstacle between the user and the vacuum cleaner that may collide with the protection means 15A. Since it must be present, it is relatively low, so that the force that lifts the vacuum cleaner from the surface to be cleaned F by the impact when the protective means 15A of the vacuum cleaner collides with a low obstacle works. As a result, the force at the time of collision is released moderately. Succoth is because it is. Further, the frequency of collision of the support body 24 on the front side of the vacuum cleaner is higher than the frequency of collision of the protection means 15A on the rear side of the vacuum cleaner. This is because, as described above, when an obstacle collides with the protection means 15A, the obstacle must be present between the user and the vacuum cleaner. For this reason, in the vacuum cleaner in a state of being used as a stick type, the protection means 15A located on the rear side of the vacuum cleaner has a relatively small collision impact when the vacuum cleaner body 1 is used alone. Even if it is formed in the expected shape and size, the electric vacuum cleaner main body 1 can be sufficiently protected from an impact caused by a collision with an obstacle.

以上のように、前記実施例においては、一端部に第一吸込口１１が形成されると共にこの第一吸込口１１に第一吸気路１２を介して接続される集塵部５及び電動送風器８を備え且つ他端部に第一把持部１０を設けた電気掃除機本体１と、この電気掃除機本体１を着脱可能に収納する収納部２を有する支持体３とを備え、この支持体３が、その一端側にノズルヘッド２６を有すると共にその他端側に第二把持部２８を有し、前記ノズルヘッド２６に第二吸込口としての横長吸込口２５を設けると共に、この横長吸込口２５と接続可能な第二吸気路３４を前記掃除機本体１の収納時に前記集塵部５及び電動送風器８に連通するように構成し、前記電気掃除機本体１の前部に保護手段１５Ａを設け、前記収納部２を前記支持体３の後側に現れるように設けると共に、この収納部２に前記保護手段１５Ａが後ろ向きとなるように前記電気掃除機本体１を収納可能に構成したことにより、前記電気掃除機本体１を単独で使用して机やテーブルの天板等の被清掃面Ｇ上を掃除する場合、被清掃面Ｇ上で前方にあるディスプレイＤ等の障害物に衝突しても、その衝撃から前記保護手段１５Ａにより前記集塵部５を保護することで、この集塵部５、ひいてはこの集塵部５が取り付けられた前記機枠ケース４内の前記電動送風器８の損傷を阻止できる。また、前記支持体３に前記電気掃除機本体１を取り付けた状態で使用して床等の被清掃面Ｆを掃除する場合、前記支持体３により前方の天板Ｔ等の障害物に電気掃除機が衝突しても前記支持体３により前記掃除機本体１を保護できると共に、前記電気掃除機を被清掃面Ｆに沿って引き寄せた際に前記電気掃除機の後部を障害物に衝突させたり、清掃中に前記第二把持部２８から手が離れて前記電気掃除機の後部を被清掃面Ｆに衝突させたりしても、前記電気掃除機の後部に位置する前記保護手段１５Ａによって、これらの衝突の衝撃から前記集塵部５、ひいてはこの集塵部５が取り付けられた前記機枠ケース４内の前記電動送風器８を保護できる。更に、前記電気掃除機本体１を単独で使用する場合の比較的小さな衝突衝撃を見込んだ形状や大きさに前記保護手段１５Ａを形成すればよいので、保護手段１５Ａを最小限のもので済ますことができ、この結果、前記電気掃除機本体１，ひいては前記電気掃除機全体を大型化させることなくコンパクトのままで済ますことができ、これによって、前記電気掃除機の操作性を維持することができる。   As described above, in the above-described embodiment, the first suction port 11 is formed at one end, and the dust collecting unit 5 and the electric blower connected to the first suction port 11 via the first intake passage 12. 8 and the other end of the vacuum cleaner main body 1 provided with a first gripping portion 10, and a support 3 having a storage portion 2 for detachably storing the vacuum cleaner main body 1. 3 has a nozzle head 26 at one end thereof and a second gripping portion 28 at the other end thereof. The nozzle head 26 is provided with a horizontally long suction port 25 as a second suction port, and the horizontally long suction port 25. A second intake passage 34 that can be connected to the vacuum cleaner main body 1 is configured to communicate with the dust collecting unit 5 and the electric blower 8 when the vacuum cleaner main body 1 is stored. Provided so that the storage portion 2 appears on the rear side of the support 3. In addition, the vacuum cleaner main body 1 can be stored in the storage portion 2 so that the protection means 15A faces rearward, so that the vacuum cleaner main body 1 can be used alone and the top of a desk or table can be used. When cleaning the surface to be cleaned G such as a plate, even if it collides with an obstacle such as a display D in front of the surface to be cleaned G, the dust collecting part 5 is protected from the impact by the protection means 15A. In this way, it is possible to prevent damage to the dust collector 5 and, consequently, the electric blower 8 in the machine casing 4 to which the dust collector 5 is attached. Further, when the surface to be cleaned F such as a floor is cleaned using the vacuum cleaner body 1 attached to the support 3, the support 3 can be used to clean an obstacle such as a top plate T in front. The vacuum cleaner main body 1 can be protected by the support body 3 even when a machine collides, and when the vacuum cleaner is drawn along the surface F to be cleaned, the rear part of the vacuum cleaner may collide with an obstacle. Even if the hand is released from the second gripping part 28 during cleaning and the rear part of the vacuum cleaner collides with the surface F to be cleaned, the protective means 15A located at the rear part of the vacuum cleaner It is possible to protect the dust collector 5 and thus the electric blower 8 in the machine casing 4 to which the dust collector 5 is attached from the impact of the collision. Furthermore, since the protection means 15A may be formed in a shape and size that allow for a relatively small impact when using the vacuum cleaner body 1 alone, the protection means 15A can be minimized. As a result, the vacuum cleaner main body 1, and thus the entire vacuum cleaner can be kept compact without increasing the size thereof, thereby maintaining the operability of the vacuum cleaner. .

また、前記保護手段１５Ａが、電気掃除機本体１を単独で使用する際の前部に対応する部位における長さ方向に設けられると共に、前記保護手段１５Ａの長さ方向、即ち前記保護手段１５Ａの中心軸線Ａが、前記支持体３の長さ方向にほぼ沿うように前記収納部２が設けられることで、前記電気掃除機本体１を単独で使用する場合、或いは前記支持体３と一緒に使用する場合に、前記保護手段１５Ａが縦向きとなり、この結果、前記保護手段１５Ａによる衝撃吸収の有効長さを可及的に大きくすることができる。   Further, the protection means 15A is provided in the length direction in a portion corresponding to the front portion when the vacuum cleaner main body 1 is used alone, and the length direction of the protection means 15A, that is, the protection means 15A. When the storage unit 2 is provided so that the central axis A is substantially along the length direction of the support 3, the vacuum cleaner main body 1 is used alone or together with the support 3. In this case, the protection means 15A is oriented vertically, and as a result, the effective length of impact absorption by the protection means 15A can be increased as much as possible.
