Conventionally, the inside of the cleaner body is divided into two spaces by a partition wall in the front and rear, and a dust collection chamber is formed in the front, and an electric blower storage chamber that stores the electric blower in the rear. The partition wall includes a flange portion connected to the bottom surface and both side surfaces of the lower case, a circular contact portion that is in the same plane as the flange portion and contacts a seal packing attached to a fan cover of the electric blower, and an electric blower And a communication port communicating with the suction port.
In the above configuration, the size of the width of the vacuum cleaner body is determined by the diameters of the flange portions and the contact portions on both sides. Therefore, in order to reduce the width of the vacuum cleaner body, the electric blower can be downsized or the flange It is conceivable to reduce the width.
However, when the electric blower is downsized, there is a problem that the power is reduced, and when the width of the flange is reduced, there is a problem that the strength of the mold is lowered and the mold is damaged.
JP 2002-253449 A (A47L 9/00)

本発明は上記欠点に鑑みなされたもので、電動送風機の小型化及び金型強度を低下させることなく掃除機本体を小型化できる電気掃除機を提供することを課題とする。   This invention is made | formed in view of the said fault, and makes it a subject to provide the vacuum cleaner which can miniaturize a vacuum cleaner main body, without reducing the size of an electric blower and mold intensity | strength.

本発明の第1の手段は、上ケースと下ケースとからなる掃除機本体と、該掃除機本体内を集塵室と電動機収納室とに区画する仕切壁と、前記電動機収納室に配置される電動送風機と、該電動送風機のファンカバーに装着されるシール部材とを備え、前記仕切壁は、下ケースの両側側面と繋がるフランジ部と、該両側フランジ部の間に少なくとも一方のフランジ部から円弧状に形成される当接部と、前記電動送風機の吸込口と連通する連通口とを有し、前記シール部材を前記当接部と、前記当接部が形成される側のフランジ部とに当接させたことを特徴とする。 The first means of the present invention is arranged in a cleaner body comprising an upper case and a lower case, a partition wall that divides the interior of the cleaner body into a dust collection chamber and a motor storage chamber, and the motor storage chamber. An electric blower and a seal member attached to a fan cover of the electric blower, and the partition wall includes a flange portion connected to both side surfaces of the lower case, and at least one flange portion between the both side flange portions. An abutting portion formed in an arc shape, and a communication port communicating with the suction port of the electric blower; the sealing member as the abutting portion; and a flange portion on a side where the abutting portion is formed; It is made to contact | abut.

また、前記当接部に、前記電動送風機側へ突出する凸部を形成することが好ましい。   Moreover, it is preferable to form the convex part which protrudes in the said contact part to the said electric blower side.

本発明によると、前記シール部材が当接する部分を円状ではなく円弧状に形成することにより、前記掃除機本体の幅方向に対する当接部の径が小さくなるので、電動送風機の小型化及び金型強度を低下させることなく掃除機本体を小型化できる。また、円弧の部分からはみでるシール部材は、前記フランジ部にて当接されるので、電動送風機の気密性を確保できる。   According to the present invention, the diameter of the contact portion with respect to the width direction of the vacuum cleaner body is reduced by forming the contact portion of the seal member in an arc shape instead of a circular shape. The vacuum cleaner body can be reduced in size without reducing the mold strength. Further, since the seal member protruding from the arc portion is brought into contact with the flange portion, the airtightness of the electric blower can be ensured.

本発明の実施の形態を図1乃至図5に基づいて以下に説明する。
1は前方に吸気口2を有する掃除機本体で、該掃除機本体1は、上面を開口した下ケース3と、該下ケース3に装着される上ケース4とから構成されている。
5は、一端が前記吸気口2に接続される可撓性を有するホースで、該ホース5の他端にはグリップ部6を有する延長管7が着脱自在に接続され、更に該延長管7の端部には床用吸込具8が取り付けられるようになっている。
9は、前記下ケース3後方の左右両側面に回動自在に支持される後車輪である。
10は、ファンカバー11とモーターケース12とからなる電動送風機で、後述する電動送風機収納室13に収納される。そして、前記ファンカバー11の外周には環状のシールパッキン14が装着されている。
15は、前記下ケース3内を前後に区画する仕切壁で、前方の空間が集塵袋を収納する集塵室16、後方の空間が前記電動送風機10を収納する電動送風機収納室13及びコードリール17を収納するコードリール収納室18が形成されている。
前記仕切壁15は、図3に示すように前記下ケース3の底面から繋がる下フランジ部19と、前記下ケース3の両側側面から繋がる左フランジ部20及び右フランジ部21と、該左フランジ部20と同一面で、前記左フランジ部20から円弧状に形成される第1当接部22と、該第1当接部22の内側に円状に形成される第2当接部23と、前記電動送風機10の吸込口24と連通する格子状の連通口25とを有している。そして、更に、前記第1当接部22、前記第2当接部23、前記左フランジ部20には、図2に示すようにそれぞれ前記電動送風機10側に突出する凸部26が形成されている。
前記第1当接部22の縦方向の直径は、前記ファンカバー11の直径と略同等(本実施例では120mm)に設定され、横方向は、図3に示す仮想線Aのように前記左フランジ部20側へはみだす(本実施例では7mm)ように設定されている。そして、前記第2当接部23は、前記第1当接部22りも内側(本実施例では7mm)にあり、前記左フランジ部20に接するように形成されている。
前記電動送風機10は、前記下ケース3から延びる複数のリブ27によって支持され、前記シールパッキン14の前面側は、前記第1当接部22の凸部26及び第2当接部23の凸部26に当接し、更に前記第1当接部22からはみだした部分(円弧からはみだした部分)は、前記左フランジ部20の前記凸部26に当接されるように配置されている。従って、前記シールパッキン14の円周面の大半は前記第1当接部22及び前記第2当接部22の前記凸部26と2重状態で密着しているので、前記電動送風機10の気密性を確実に保持できる構成になっている。
ところで、前記下ケース3は、樹脂成形によって製作されるが、その金型構成を図4に示す。
28は、主に前記左フランジ部20、前記右フランジ部21、前記電動機収納室13の後方、前記コードリール収納室18を成形する第1金型で、上下方向にスライドする。
29は、主に格子状の前記連通口25、前記第1当接部22、前記第2当接部23を成形する第2金型で、前後方向にスライドする。
前記左フランジ部20の幅は、前記第1金型28の左サイド部28aの厚さによって決定されるが、前記掃除機本体1の幅方向を小さくするために、前記左フランジ部20の幅を狭くすると、前記第1金型28の左サイド部28aが薄くなって破損してしまう恐れがあり、前記左フランジ部28の幅は、従来製品から変わらないように設定されている。
An embodiment of the present invention will be described below with reference to FIGS.
Reference numeral 1 denotes a vacuum cleaner body having an air inlet 2 in the front. The vacuum cleaner body 1 includes a lower case 3 having an upper surface opened and an upper case 4 attached to the lower case 3.
Reference numeral 5 denotes a flexible hose having one end connected to the air inlet 2, and an extension pipe 7 having a grip portion 6 is detachably connected to the other end of the hose 5. The floor suction tool 8 is attached to the end.
Reference numeral 9 denotes a rear wheel that is rotatably supported on the left and right side surfaces behind the lower case 3.
Reference numeral 10 denotes an electric blower including a fan cover 11 and a motor case 12, and is housed in an electric blower storage chamber 13 described later. An annular seal packing 14 is attached to the outer periphery of the fan cover 11.
15 is a partition wall that divides the inside of the lower case 3 into the front and rear, a dust collection chamber 16 in which the front space stores the dust bag, a motor blower storage chamber 13 in which the rear space stores the electric blower 10 and a cord A cord reel storage chamber 18 for storing the reel 17 is formed.
As shown in FIG. 3, the partition wall 15 includes a lower flange portion 19 connected from the bottom surface of the lower case 3, a left flange portion 20 and a right flange portion 21 connected from both side surfaces of the lower case 3, and the left flange portion. 20, a first contact portion 22 formed in an arc shape from the left flange portion 20, a second contact portion 23 formed in a circular shape inside the first contact portion 22, A grid-like communication port 25 communicating with the suction port 24 of the electric blower 10 is provided. Further, as shown in FIG. 2, the first contact portion 22, the second contact portion 23, and the left flange portion 20 are each provided with a convex portion 26 that protrudes toward the electric blower 10 side. Yes.
The diameter of the first contact portion 22 in the vertical direction is set to be substantially equal to the diameter of the fan cover 11 (120 mm in this embodiment), and the horizontal direction is the left of the left side as indicated by an imaginary line A shown in FIG. It is set to protrude to the flange portion 20 side (7 mm in this embodiment). The second abutting portion 23 is also inside the first abutting portion 22 (7 mm in this embodiment) and is formed so as to contact the left flange portion 20.
The electric blower 10 is supported by a plurality of ribs 27 extending from the lower case 3, and the front side of the seal packing 14 is a convex portion 26 of the first abutting portion 22 and a convex portion of the second abutting portion 23. 26 and a portion protruding from the first contact portion 22 (a portion protruding from the circular arc) is disposed so as to be in contact with the convex portion 26 of the left flange portion 20. Accordingly, most of the circumferential surface of the seal packing 14 is in close contact with the convex portions 26 of the first contact portion 22 and the second contact portion 22 in a double state. It is the structure which can hold the property reliably.
Incidentally, the lower case 3 is manufactured by resin molding, and its mold configuration is shown in FIG.
Reference numeral 28 denotes a first mold that mainly molds the left flange portion 20, the right flange portion 21, the rear of the electric motor storage chamber 13, and the cord reel storage chamber 18, and slides in the vertical direction.
Reference numeral 29 denotes a second mold that molds the grid-shaped communication port 25, the first contact portion 22, and the second contact portion 23, and slides in the front-rear direction.
The width of the left flange portion 20 is determined by the thickness of the left side portion 28a of the first mold 28. In order to reduce the width direction of the cleaner body 1, the width of the left flange portion 20 is determined. If the width is narrowed, the left side portion 28a of the first mold 28 may be thinned and damaged, and the width of the left flange portion 28 is set so as not to change from that of the conventional product.

本実施例では、前記掃除機本体1の幅方向を小さくするために、前記シールパッキン14が当接する前記第1当接部22を円状ではなく円弧状に形成している。この形状とすることで、前記掃除機本体1の幅方向に対する前記第1当接部22の径が小さくなるので、前記電動送風機10の小型化及び金型強度を低下させることなく前記掃除機本体1を小型化できるようになる。   In the present embodiment, in order to reduce the width direction of the cleaner body 1, the first abutting portion 22 with which the seal packing 14 abuts is formed in an arc instead of a circle. By adopting this shape, the diameter of the first contact portion 22 with respect to the width direction of the vacuum cleaner main body 1 is reduced, so that the vacuum cleaner main body without reducing the size and mold strength of the electric blower 10. 1 can be miniaturized.

ただし、上記構成における前記下ケース3の金型構成は、図5に示すように前記第1金型28と前記第2金型29の境界面が前記左フランジ部20の端部に位置するため、境界面においてバリ30が発生する。前記左フランジ部20には、前記シールパッキン14が当接するため、前記バリ30があると前記シールパッキン14と前記左フランジ部20との間に隙間が生じ、気密性が低下するという問題が発生する。従って、本実施例では、前記第1当接部22、前記第2当接部23、前記左フランジ部20に、前記バリ30よりも高い前記凸部26を形成することにより(本実施例では0.7mm)、前記バリ30による隙間の発生を解消し、気密性が低下することを防止できる構成となっている。
上記構成によって、前記掃除機本体1の幅を小さくするために、前記シールパッキン14が当接する前記第1当接部22を円状ではなく円弧状に形成することによって、前記掃除機本体1の幅方向に対する前記第1当接部22の径を小さくすることができるので、前記電動送風機10を小型化して吸引力を低下させたり、あるいは前記左フランジ部20の幅を狭くして金型強度を低下させるという構成を取ることなく、前記掃除機本体1の幅を小さくすることができる。
However, the mold configuration of the lower case 3 in the above configuration is because the boundary surface between the first mold 28 and the second mold 29 is located at the end of the left flange portion 20 as shown in FIG. The burr 30 is generated at the boundary surface. Since the seal packing 14 comes into contact with the left flange portion 20, if there is the burr 30, a gap is generated between the seal packing 14 and the left flange portion 20, resulting in a problem that airtightness is lowered. To do. Therefore, in this embodiment, the first contact portion 22, the second contact portion 23, and the left flange portion 20 are formed with the convex portion 26 higher than the burr 30 (in this embodiment, 0.7 mm), the generation of a gap due to the burr 30 is eliminated, and the airtightness can be prevented from being lowered.
With the above configuration, in order to reduce the width of the cleaner body 1, the first contact portion 22 with which the seal packing 14 abuts is formed in an arc shape instead of a circle shape. Since the diameter of the first contact portion 22 in the width direction can be reduced, the electric blower 10 can be downsized to reduce the suction force, or the left flange portion 20 can be narrowed to reduce the mold strength. The width of the vacuum cleaner main body 1 can be reduced without taking the configuration of lowering.

尚、上記の実施形態では、前記電動送風機10の右隣に前記コードリール収納室18を設けているため、前記右フランジ部21には前記第1当接部22がはみだすようにしていないが、前記コードリール収納室18を前記電動送風機10の後方あるいは下側に設ける構成であれば、前記第1当接部22が前記左フランジ部20と前記右フランジ部21の両側にはみだすような円弧状の形態とすれば、前記掃除機本体1の幅をより一層小さくすることができる。   In the above embodiment, since the cord reel storage chamber 18 is provided on the right side of the electric blower 10, the first contact portion 22 does not protrude from the right flange portion 21. If the cord reel storage chamber 18 is provided behind or below the electric blower 10, the first contact portion 22 has an arc shape that protrudes on both sides of the left flange portion 20 and the right flange portion 21. If it is set as this form, the width | variety of the said vacuum cleaner main body 1 can be made still smaller.
