Description

本発明は、電気掃除機の吸込具に係り、特に、吸込具を軽量化しても強度の低下を抑制する電気掃除機の吸込具に関するものである。 The present invention relates to a suction tool for a vacuum cleaner, and more particularly to a suction tool for a vacuum cleaner that suppresses a decrease in strength even if the suction tool is reduced in weight.

従来，電気掃除機の吸込具の吸口本体（本体ケース）は、吸口上ケース（上ケース）と吸口下ケース（下ケース）とから構成される。図１５は従来の電気掃除機吸込具の吸口下ケースの例であり、吸込具の吸口本体の強度を確保するために、吸口下ケースの強度を高めている。具体的には、補強架部６６が、前側縁枠部６４と後側縁枠部６８とに架けるように設けられる。前側縁枠部６６は窓開口６３に沿って長く延びているので、吸口上ケース９の上から押されると容易に撓む。しかし、前側縁枠部６４は補強架部６６により梁のように支持されるので、吸口上ケース９の上から押されても容易に撓まない。このように、補強架部６６を後側縁枠部６８から前側縁枠部６４に架ける簡単な構成により、機械的強度の強い構造となっている（特許文献１参照。）。 Conventionally, a suction body (main body case) of a suction tool of a vacuum cleaner is composed of a suction upper case (upper case) and a suction lower case (lower case). FIG. 15 is an example of a lower case of a conventional vacuum cleaner suction tool, and the strength of the lower suction case is increased in order to ensure the strength of the suction body of the suction tool. Specifically, the reinforcing frame portion 66 is provided so as to be laid over the front side edge frame portion 64 and the rear side edge frame portion 68. Since the front edge frame portion 66 extends long along the window opening 63, it easily bends when pressed from above the upper suction case 9. However, since the front side edge frame portion 64 is supported like a beam by the reinforcing frame portion 66, it is not easily bent even if it is pushed from above the inlet case 9. As described above, a simple structure in which the reinforcing frame 66 is bridged from the rear edge frame portion 68 to the front edge frame portion 64 has a structure with high mechanical strength (see Patent Document 1).

次に、動作について説明する。
電気掃除機本体２に内蔵された電源コードをコンセントに接続し、手元部３ａに設けられた操作部３ｂを操作することにより、電気掃除機本体２内の電動送風機が駆動され、吸引風が発生する。この吸引風により、被掃除面である床面等から塵埃とともに空気が、吸込具５の本体ケース６の下面の吸引口６２ｃから、接続管１０（回動管１１、継手管１２０）、パイプ４、ホース３を経由して電気掃除機本体２に取り込まれる。電気掃除機本体２に取り込まれた塵埃を含む空気は、塵埃が集塵室に貯留され、塵埃の除去された空気が電気掃除機本体から排出される。 Next, the operation will be described.
By connecting the power cord built in the vacuum cleaner body 2 to an outlet and operating the operation part 3b provided on the hand part 3a, the electric blower in the vacuum cleaner body 2 is driven and suction air is generated. To do. Due to this suction air, air together with dust from the floor surface or the like to be cleaned is supplied from the suction port 62 c on the lower surface of the main body case 6 of the suction tool 5 to the connecting pipe 10 (rotating pipe 11, joint pipe 120), pipe 4. The vacuum cleaner body 2 is taken in via the hose 3. The air containing the dust taken into the vacuum cleaner body 2 is stored in the dust collection chamber, and the air from which the dust has been removed is discharged from the vacuum cleaner body.

操作部３ｂで電動送風機を駆動する操作を行うと、吸込具５の本体ケース６内に配設された回転ブラシ６４を回転駆動して、被掃除面の塵埃を掻きあげるように、回転ブラシ６４を駆動するブラシモーター６３ａへ電力が供給される。この電力は、電気掃除機本体２からホース３、パイプ４、継手管１２０、回動管１１、吸込具５の本体ケース３内に配設される、ブラシモーター６３ａを制御する制御部６３ｃを経由してブラシモーター６３ａへ供給される。 When the operation unit 3b is operated to drive the electric blower, the rotary brush 64 is driven to rotate the rotary brush 64 disposed in the main body case 6 of the suction tool 5 so as to scrape dust on the surface to be cleaned. Electric power is supplied to the brush motor 63a that drives the motor. This electric power is supplied from the vacuum cleaner body 2 to the hose 3, the pipe 4, the joint pipe 120, the rotating pipe 11, and the control unit 63 c that controls the brush motor 63 a that is disposed in the main body case 3 of the suction tool 5. Then, it is supplied to the brush motor 63a.

掃除をする際に、使用者が手元部３ａを把持して被掃除面上を吸込具５を移動させる。吸込具５を移動すると壁や家具に衝突することがあり、吸込具５に前後、上下、左右方向から衝突による荷重が加わる。また、吸込具５を誤って落下させると、落下衝撃による荷重か加わる。 When cleaning, the user holds the hand portion 3a and moves the suction tool 5 on the surface to be cleaned. When the suction tool 5 is moved, it may collide with a wall or furniture, and a load due to the collision is applied to the suction tool 5 from front and rear, up and down, and left and right. Moreover, if the suction tool 5 is accidentally dropped, a load due to a drop impact is applied.

上ケース６１の前端下方に形成された４個の第１のリブ６１ａが下ケース６２の前端上部に形成された４個の第１の被係止部６２ｄに係止される。第１のリブ６１ａの下端が第１の被係止部６２ｄの底部被係止部６２ｄ２と当接するので、上ケース６１ａに対し上方から加わった荷重は、複数の第１のリブ６１ａから複数の第１の被係止部６２ｄへ伝達される。このように、荷重が上ケース６１と下ケース６２とに分散されて、上方からの荷重による上ケース６１及び下ケース６２の変形が低減され、壊れにくくなるという意味で強度が高まる。さらに、上ケース６１を下ケース６２に固定して本体ケース６を組み立てるときに、第１の被係止部６２ｄが第１のリブ６１ａの位置決めの目安となるので、組み立て性、組み立て効率が改善される。 The four first ribs 61 a formed below the front end of the upper case 61 are locked to the four first locked portions 62 d formed on the upper front end of the lower case 62. Since the lower end of the first rib 61a comes into contact with the bottom locked portion 62d2 of the first locked portion 62d, the load applied to the upper case 61a from above is divided into a plurality of loads from the plurality of first ribs 61a. It is transmitted to the first locked portion 62d. In this way, the load is distributed to the upper case 61 and the lower case 62, and the deformation of the upper case 61 and the lower case 62 due to the load from above is reduced and the strength is increased in the sense that it is difficult to break. Furthermore, when the upper case 61 is fixed to the lower case 62 and the main body case 6 is assembled, the first locked portion 62d serves as a guide for positioning the first rib 61a, so that the assembling property and the assembling efficiency are improved. Is done.

なお、底部被係止部６２ｄ２が第１のリブ６１ａの下端と近接して対向するように形成される場合は、上方からの荷重により上ケース６１が下方に変形したときに、第１のリブ６１ａの下端が第１の被係止部６２ｄの底部被係止部６２ｄ２と当接するので、上記と同様に、上ケース６１ａに対し上方から加わった荷重は、複数の第１のリブ６１ａから複数の第１の被係止部６２ｄへ伝達され、荷重が上ケース６１と下ケース６２とに分散されて、上方からの荷重による上ケース６１及び下ケース６２の変形が低減され、壊れにくくなる。このように、上ケース６１及び下ケース６２の変形が低減されるという意味で必要な強度が確保される。 When the bottom locked portion 62d2 is formed so as to face the lower end of the first rib 61a close to the first rib 61a, when the upper case 61 is deformed downward by a load from above, the first rib Since the lower end of 61a abuts against the bottom locked portion 62d2 of the first locked portion 62d, the load applied from above to the upper case 61a is a plurality of loads from the plurality of first ribs 61a as described above. The load is distributed to the upper case 61 and the lower case 62, the deformation of the upper case 61 and the lower case 62 due to the load from above is reduced, and it is difficult to break. Thus, the required strength is ensured in the sense that the deformation of the upper case 61 and the lower case 62 is reduced.

また、第１の被係止部６２ｅの一対の側部被係止部６２ｄ１が第１のリブ６１ａの両端部、及びこれらに連なる後面の少なくとも一部を覆うので、上ケース６１に対し前後方向から加わった荷重は、複数の第１のリブ６１ａから複数の第１の被係止部６２ｄへ伝達される。このように、荷重が上ケース６１と下ケース６２とに分散されて、前後方向からの荷重による上ケース６１及び下ケース６２の変形が低減され、壊れにくくなる。
なお、上ケース６１に対し左右方向から荷重が加わった場合でも、複数の第１のリブ６１ａから複数の第１の被係止部６２ｄへ伝達される。ここで、第１のリブ６１ａの両側丹部と側部被係止部６２ｄ１との隙間は小さい方が望ましい。このように、荷重が上ケース６１と下ケース６２とに分散されて、左右方向からの荷重による上ケース６１及び下ケース６２の変形が低減され、壊れにくくなる。 Further, since the pair of side locked portions 62d1 of the first locked portion 62e covers both ends of the first rib 61a and at least a part of the rear surface connected to these, the front and rear direction with respect to the upper case 61 Is applied to the plurality of first locked portions 62d from the plurality of first ribs 61a. In this way, the load is distributed to the upper case 61 and the lower case 62, so that deformation of the upper case 61 and the lower case 62 due to the load from the front and rear direction is reduced, and it is difficult to break.
Even when a load is applied to the upper case 61 from the left and right directions, the load is transmitted from the plurality of first ribs 61a to the plurality of first locked portions 62d. Here, it is desirable that the gap between the both side tongues of the first rib 61a and the side locked portion 62d1 is small. In this way, the load is distributed to the upper case 61 and the lower case 62, so that deformation of the upper case 61 and the lower case 62 due to the load from the left and right direction is reduced and it is difficult to break.

また、第１のリブ６１ａは前後方向に扁平な板状体であり、第１のリブ６１ａの後面の両端部の根元部には、第１のリブ６１ａの前後方向の変形を抑制して強度を高める一対の補強リブ６１ａ１が形成されるので、第１のリブ６１ａに対し前後方向から荷重が加わっても補強リブ６１ａ１が第１のリブ６１ａの変形を抑制し、強度が高まる。 In addition, the first rib 61a is a plate-like body that is flat in the front-rear direction, and has a strength that suppresses deformation in the front-rear direction of the first rib 61a at the root portions of both ends of the rear surface of the first rib 61a. Since the pair of reinforcing ribs 61a1 are formed, the reinforcing rib 61a1 suppresses deformation of the first rib 61a even when a load is applied to the first rib 61a from the front-rear direction, and the strength is increased.

また、上ケース６１または下ケース６２に対し、両者を離間する方向の荷重が加わっても、第２のリブ６１ｂの爪部６１ｂ１が下ケース６２の前端の裏面に形成された第２の被係止部６２ｅの孔部６２ｅ１に係止されるので、上ケース６１と下ケース６２とが離間するのを防止する。 Further, even when a load in the direction of separating the two is applied to the upper case 61 or the lower case 62, the claw portion 61b1 of the second rib 61b is formed on the back surface of the front end of the lower case 62. Since it is latched by the hole 62e1 of the stopper 62e, the upper case 61 and the lower case 62 are prevented from separating.

また、第２のリブ６１ｂを第１のリブ６１ａと異なる位置に配置したので、両者が干渉することがない。その結果、両者の設計の自由度が高まる。 Moreover, since the 2nd rib 61b was arrange | positioned in the position different from the 1st rib 61a, both do not interfere. As a result, the degree of freedom of design of both increases.

また、下ケース６２の前端下端に、後方に向かって垂れ下がる５個の垂下部６２２ａ、６２２ｂ、６２２ｃ、６２２ｄ、６２２ｅが形成されるので、垂下部６２２がない場合と比較し、枠状体である下ケース６２の剛性が高まる。
また、垂下部６２２を、第１の被係止部６２ｄと異なるに配置したので、垂下部６２２と第１の被係止部６２ｄとが干渉することなく配置できる。その結果、両者の設計の自由度が高まる。
また、電気掃除機本体２に内蔵される電動送風機の駆動音が、ホース３、パイプ４内を通り、吸込具５内に伝達されるが、中央の垂下部６２２ｃを回動管１１の円筒部１１ｃの前面開口（本体ケース６側への開口）の前方に配置したので、振動音が吸込具５の前方の空間に伝わるのを抑制できる。 Further, since five hanging portions 622a, 622b, 622c, 622d, and 622e hanging downward are formed at the lower end of the front end of the lower case 62, the frame is a frame-like body as compared with the case where there is no hanging portion 622. The rigidity of the lower case 62 is increased.
Moreover, since the drooping portion 622 is arranged differently from the first locked portion 62d, the drooping portion 622 and the first locked portion 62d can be arranged without interference. As a result, the degree of freedom of design of both increases.
In addition, the driving sound of the electric blower built in the vacuum cleaner body 2 passes through the hose 3 and the pipe 4 and is transmitted to the suction tool 5, but the central hanging portion 622 c passes through the cylindrical portion of the rotating tube 11. Since it arrange | positions ahead of the front opening of 11c (opening to the main body case 6 side), it can suppress that a vibration sound is transmitted to the space ahead of the suction tool 5. FIG.

なお、上記実施の形態１では、上ケース６１に荷重が加わる場合の例を説明したが、下ケース６２に荷重が加わる場合も、上ケース６１に荷重が分散され、軽量で必要な強度を確保する吸込具及びこれを用いた電気掃除機を得ることができる。 In the first embodiment, an example in which a load is applied to the upper case 61 has been described. However, even when a load is applied to the lower case 62, the load is distributed to the upper case 61, and the required strength is ensured with light weight. And a vacuum cleaner using the same.

However, the lower case 62 is provided with the first rib 61a, and the upper case 61 is provided with the first rib 61a. A locked portion 62d may be provided.
Similarly, the second rib 61 b is provided on the upper case 61 and the second locked portion 62 e is provided on the lower case 62. However, the second rib 61 b is provided on the lower case 62 and the second case 61 is provided on the upper case 61. A locked portion 62e may be provided.

このように、実施の形態１の電気掃除機の吸込具によれば、下面に開口した吸込口を有する本体ケースと、この本体ケースに接続される接続管とを備えた電気掃除機の吸込具において、本体ケースは、上ケースと下ケースとを有し、下ケースに吸込口が形成され、上ケースの前端には下方に突出する複数の第１のリブを備え、下ケースの前端には複数の第１のリブが係止される第１の被係止部を備え、第１のリブは前後方向に扁平な板状体であり、第１の被係止部は、第１のリブの両端部、及びこれらに連なる後面の少なくとも一部を覆う一対の側部被係止部と、第１のリブの下端と当接若しくは近接して対向する底部被係止部とを備えたので、上ケースに加わる荷重が、上ケースに形成された複数の第１のリブ、及び、下ケースに形成された複数の第１の被係止部を介して下ケースに加わるので、荷重が分散され、軽量で必要な強度を確保する吸込具及びこれを用いた電気掃除機を得ることができる。 Thus, according to the suction tool of the vacuum cleaner of Embodiment 1, the suction tool of the vacuum cleaner provided with the main body case which has the suction opening opened in the lower surface, and the connection pipe connected to this main body case. The main body case has an upper case and a lower case, a suction port is formed in the lower case, a front end of the upper case is provided with a plurality of first ribs projecting downward, and a front end of the lower case is A first locked portion to which a plurality of first ribs are locked is provided. The first rib is a plate-like body that is flat in the front-rear direction, and the first locked portion is a first rib. And a pair of side locked parts that cover at least a part of the rear surface that is continuous with these, and a bottom locked part that is in contact with or close to the lower end of the first rib. The load applied to the upper case is formed on the plurality of first ribs formed on the upper case and the lower case. Since joining the lower case through a plurality of first to-be engaged portion, the load which is dispersed, can be obtained suction device to secure the required strength, lightweight and electric vacuum cleaner using the same.

例えば、従来の下ケースの強度を高める場合と比較し、下ケース６２単品では肉厚２ｍｍ未満に抑え、下ケース６２の使用プラスチック量も最少にし、デザイン上必要になる上ケース６１と噛み合せることにより、前方からの衝撃による荷重、横方向からの衝撃による荷重、落下衝撃による荷重等に耐えうる吸込具としての必要で十分な強度を確保することができる。 For example, compared with the case where the strength of the conventional lower case is increased, the thickness of the lower case 62 is limited to less than 2 mm, the amount of plastic used in the lower case 62 is minimized, and the upper case 61 is meshed with the design required. Thus, the necessary and sufficient strength can be ensured as a suction tool capable of withstanding a load due to an impact from the front, a load due to a lateral impact, a load due to a drop impact, and the like.

また、複数の第１のリブに前後方向の変形を抑制する補強リブを備えたので、第１のリブに対し前後方向から荷重が加わっても補強リブが第１のリブの変形を抑制し、強度が高まる。 In addition, since the plurality of first ribs are provided with reinforcing ribs that suppress the deformation in the front-rear direction, the reinforcing ribs suppress the deformation of the first ribs even when a load is applied from the front-rear direction to the first ribs. Strength increases.

また、上ケースの前端には下方に突出する第２のリブを備え、第２のリブには爪部が形成され、下ケースの前端には爪部が係止される第２の被係止部を備えたので、爪部が第２の被係止部と係止されることにより上ケースの前端が下ケースの前端と上下方向に離間するのを防止する。 In addition, a second rib protruding downward is provided at the front end of the upper case, a claw portion is formed on the second rib, and a second locked state in which the claw portion is locked at the front end of the lower case. Since the claw portion is locked with the second locked portion, the front end of the upper case is prevented from being separated from the front end of the lower case in the vertical direction.

また、第２のリブを第１のリブと異なる位置に配置したので、両者が干渉することがなく、両者の設計の自由度が高まる。 Further, since the second rib is disposed at a position different from that of the first rib, they do not interfere with each other, and the degree of freedom in designing both is increased.

また、下ケースの前端下端に、後方に向かって垂れ下がる垂下部を備えたので、下ケースの剛性が高まる。 Moreover, since the lower end of the lower end of the lower case is provided with a hanging portion that hangs downward, the rigidity of the lower case is increased.

また、垂下部を、第１の被係止部と異なる位置に配置したので、垂下部と第１の被係止部とが干渉することなく配置でき、両者の設計の自由度が高まる。 Moreover, since the drooping portion is disposed at a position different from the first locked portion, the drooping portion and the first locked portion can be disposed without interfering with each other, and the degree of freedom in designing both is increased.

さらに、垂下部を、接続管の本体ケース側への開口の前方に配置したので、掃除機本体側から伝わる騒音が吸込具から前方に伝わるのを抑制できる。 Furthermore, since the drooping portion is disposed in front of the opening to the main body case side of the connection pipe, it is possible to suppress the noise transmitted from the cleaner main body side from being transmitted forward from the suction tool.

実施の形態２．
図１４は、実施の形態２における電気掃除機の吸込具の下ケースを上から見た斜視図である。実施の形態１と構成が異なる点は、吸込具５の下ケース６２の前端が二重壁６２３により形成されるとともに、二重壁６２３間に上下方向に延在して二重壁６２３間を複数仕切る仕切り部６２４を備え、複数の第１のリブが仕切り部６２４により複数仕切られる二重壁６２３の間に挿入されるともに、複数の第１のリブ６１ａの横幅が仕切り部６２４により複数区切られる二重壁６２３の横幅と略同じであり、二重壁６２３が第１のリブ６１ａの下端と当接若しくは近接して対向する二重壁底部（図示せず）を有する点である。 Embodiment 2. FIG.
FIG. 14 is a perspective view of the lower case of the suction tool of the electric vacuum cleaner according to Embodiment 2 as viewed from above. The difference from the first embodiment is that the front end of the lower case 62 of the suction tool 5 is formed by a double wall 623 and extends between the double walls 623 in the vertical direction between the double walls 623. A plurality of partitioning portions 624 are provided, and a plurality of first ribs are inserted between the double walls 623 partitioned by the partitioning portions 624, and the lateral widths of the plurality of first ribs 61a are partitioned by the partitioning portions 624. The double wall 623 is substantially the same as the horizontal width of the double wall 623, and the double wall 623 has a double wall bottom (not shown) that is in contact with or close to the lower end of the first rib 61 a.

二重壁６２３の内の前方側の壁は、実施の形態１における下ケース６２の前端の壁に相当する。二重壁６２３の内の前方側の壁は、実施の形態１における第１の被係止部６２ｄの側部被係止部６２ｄ２について、下ケース６２の前端の壁と平行な後端部を左右方向に延設して、１枚の壁を形成したものと同等である。また、仕切り部６２４は、実施の形態１における第１の被係止部６２ｄの側部被係止部６２ｄ１について、下ケース６２の前端の壁と直交する部分に相当する。さらに、二重壁底部は、実施の形態１における第１の被係止部６２ｄの底部被係止部６２ｄ２に相当する。 The front wall of the double wall 623 corresponds to the front end wall of the lower case 62 in the first embodiment. The front wall of the double wall 623 has a rear end portion parallel to the front end wall of the lower case 62 with respect to the side locked portion 62d2 of the first locked portion 62d in the first embodiment. It is the same as that extending in the left-right direction and forming one wall. Further, the partition portion 624 corresponds to a portion orthogonal to the front end wall of the lower case 62 with respect to the side locked portion 62d1 of the first locked portion 62d in the first embodiment. Furthermore, the double wall bottom corresponds to the bottom locked portion 62d2 of the first locked portion 62d in the first embodiment.

実施の形態１と同様に、上ケース６１の前端下方に形成された４個の第１のリブ６１ａが下ケース６２の二重壁６２３の間に形成された仕切り部６２４で仕切られた部分に挿入され、第１のリブ６１ａの下端が二重壁底部と当接するので、上ケース６１ａに対し上方から加わった荷重は、複数の第１のリブ６１ａから二重壁底部へ伝達される。このように、荷重が上ケース６１と下ケース６２とに分散されて、上方からの荷重による上ケース６１及び下ケース６２の変形が低減され、壊れにくくなるという意味で強度が高まる。 As in the first embodiment, the four first ribs 61 a formed below the front end of the upper case 61 are partitioned by a partition portion 624 formed between the double walls 623 of the lower case 62. Since the lower end of the first rib 61a is in contact with the bottom of the double wall, the load applied to the upper case 61a from above is transmitted from the plurality of first ribs 61a to the bottom of the double wall. In this way, the load is distributed to the upper case 61 and the lower case 62, and the deformation of the upper case 61 and the lower case 62 due to the load from above is reduced and the strength is increased in the sense that it is difficult to break.

なお、第１のリブ６１ａの下端が二重壁底部と近接して対向するように形成される場合は、上方からの荷重により上ケース６１が下方に変形したときに、第１のリブ６１ａの下端が二重壁底部と当接するので、上記と同様に、上ケース６１ａに対し上方から加わった荷重は、複数の第１のリブ６１ａから二重壁底部へ伝達され、荷重が上ケース６１と下ケース６２とに分散されて、上方からの荷重による上ケース６１及び下ケース６２の変形が低減され、壊れにくくなる。 When the lower end of the first rib 61a is formed so as to face the double wall bottom in close proximity, when the upper case 61 is deformed downward by a load from above, the first rib 61a Since the lower end is in contact with the bottom of the double wall, similarly to the above, the load applied to the upper case 61a from above is transmitted from the plurality of first ribs 61a to the bottom of the double wall. Dispersed in the lower case 62, the deformation of the upper case 61 and the lower case 62 due to the load from above is reduced, making it difficult to break.

また、上ケース６１の前端下方に形成された４個の第１のリブ６１ａが下ケース６２の二重壁６２３の間に形成された仕切り部６２４で仕切られた部分に挿入され、第１のリブ６１ａは前後方向に扁平な板状体であるから、上ケース６１に対し前後方向から加わった荷重は、複数の第１のリブ６１ａから二重壁６２３へ伝達される。ここで、第１のリブ６１ａの前後方向の暑さが二重壁６２３の前後方向の間隔と略同一であることが望ましい。このように、荷重が上ケース６１と下ケース６２とに分散されて、前後方向からの荷重による上ケース６１及び下ケース６２の変形が低減され、壊れにくくなるという意味で強度が高まる。 Also, the four first ribs 61a formed below the front end of the upper case 61 are inserted into a portion partitioned by a partition portion 624 formed between the double walls 623 of the lower case 62, and the first Since the rib 61 a is a plate-like body that is flat in the front-rear direction, the load applied from the front-rear direction to the upper case 61 is transmitted from the plurality of first ribs 61 a to the double wall 623. Here, it is desirable that the heat in the front-rear direction of the first rib 61 a is substantially the same as the distance in the front-rear direction of the double wall 623. In this way, the load is distributed to the upper case 61 and the lower case 62, and the deformation of the upper case 61 and the lower case 62 due to the load from the front and rear direction is reduced, and the strength is increased in the sense that it is difficult to break.

また、複数の第１のリブ６１ａの横幅が仕切り部６２４により複数区切られる二重壁６２３の横幅と略同じであるので、上ケース６１に対し左右方向から荷重が加わった場合でも、複数の第１のリブ６１ａから仕切り部６２４へ伝達される。このように、荷重が上ケース６１と下ケース６２とに分散されて、左右方向からの荷重による上ケース６１及び下ケース６２の変形が低減され、壊れにくくなる。 In addition, since the horizontal width of the plurality of first ribs 61a is substantially the same as the horizontal width of the double wall 623 divided by the partition portion 624, even when a load is applied to the upper case 61 from the left and right directions, 1 is transmitted from one rib 61 a to the partition 624. In this way, the load is distributed to the upper case 61 and the lower case 62, so that deformation of the upper case 61 and the lower case 62 due to the load from the left and right direction is reduced and it is difficult to break.

また、下ケース６２の前端を二重壁６２３で形成したので、１枚の壁で構成した場合と比較し、枠状体である下ケース６２の剛性が高まる。 In addition, since the front end of the lower case 62 is formed of the double wall 623, the rigidity of the lower case 62, which is a frame-like body, is increased as compared with the case where the lower case 62 is formed of a single wall.

このように、実施の形態２の電気掃除機の吸込具によれば、下面に開口した吸込口を有する本体ケースと、この本体ケースに接続される接続管とを備えた電気掃除機の吸込具において、本体ケースは、上ケースと下ケースとを有し、下ケースに吸込口が形成され、上ケースの前端には下方に突出する複数の第１のリブを備え、第１のリブは前後方向に扁平な板状体であり、下ケースの前端は二重壁により形成されるとともに、二重壁間に上下方向に延在して前記二重壁間を複数仕切る仕切り部を備え、複数の第１のリブが仕切り部により複数仕切られる二重壁の間に挿入されるともに、複数の第１のリブの横幅が仕切り部により複数区切られる二重壁の横幅と略同じであり、二重壁が第１のリブの下端と当接若しくは近接して対向する二重壁底部を有するので、上ケースに加わる荷重が、上ケースに形成された複数の第１のリブ、及び、下ケースに形成された二重壁を介して下ケースに加わり、荷重が分散され、軽量で必要な強度を確保する吸込具及びこれを用いた電気掃除機を得ることができる。 Thus, according to the suction tool of the vacuum cleaner of Embodiment 2, the suction tool of the vacuum cleaner provided with the main body case which has the suction opening opened in the lower surface, and the connection pipe connected to this main body case. The main body case has an upper case and a lower case, a suction port is formed in the lower case, and a plurality of first ribs projecting downward are provided at the front end of the upper case. The front end of the lower case is formed by a double wall, and includes a partition portion that extends in the vertical direction between the double walls and partitions the double walls. The first ribs are inserted between the double walls partitioned by the partition part, and the lateral widths of the plurality of first ribs are substantially the same as the lateral widths of the double walls partitioned by the partition part. Double wall whose heavy wall is in contact with or close to the lower end of the first rib Since the load is applied to the upper case, the load applied to the upper case is applied to the lower case via the plurality of first ribs formed on the upper case and the double wall formed on the lower case, and the load is dispersed and lightweight. Therefore, it is possible to obtain a suction tool that secures the necessary strength and a vacuum cleaner using the suction tool.
