Description

【0001】
【発明の属する技術分野】
本発明は、キャニスタ型等の電気掃除機に関する。
【0002】
【従来の技術】
電気掃除機には、例えば、掃除機本体主部及び蓋部を有する掃除機本体を備えて、掃除機本体主部の集塵室の開口部を掃除機本体主部の上側に設けられた蓋部で開閉するものがある。
【0003】
掃除機本体主部は、例えばポリプロピレン等により形成されている。掃除機本体主部の内部には、送風室、及び、この送風室の吸込み上流側に配置されて、上端面に開口部が設けられた集塵室を有している。送風室には電動送風機が収容されている。集塵室には、開口部から出し入れ可能な集塵フィルタが収容されている。また、集塵室には、開口部の縁に沿ってシール材が設けられている。
【0004】
蓋部は、例えばABS樹脂等により形成されている。この蓋部は、掃除機本体主部の後端部に、ヒンジ金具を介して集塵室の開口部を開く開き位置とこの開口部を閉じる閉じ位置とにわたって回動自在となるように設けられている。
【0005】
この電気掃除機では、蓋部の前端部に係合部が設けられているとともに、掃除機本体主部の前端部に蓋部の係合部と係合する係合受け部が設けられている。そして、蓋部を閉じて係合部を掃除機本体主部の係合受け部に係合させることで、蓋部と掃除機本体主部とをシール材を介して密着させて、集塵室を気密状態に保持できるように形成されている。
【0006】
この電気掃除機は、掃除機本体に可撓性ホースからなる吸塵ホースの一端部を連結し、この吸塵ホースの他端部に硬質な延長管の一端部を連結し、この延長管の他端部に吸込み口体を連結して使用する。そして、電動送風機によって形成される気流により、吸込み口体から空気とともに塵埃を吸込み、吸塵ホース及び延長管で掃除機本体の集塵室に導くことで、この集塵室内の集塵フィルタで塵埃を捕捉する。集塵室の集塵フィルタを通過した空気は、掃除機本体の外部に排出される。
【0007】
【発明が解決しようとする課題】
ところで、電気掃除機は、取扱い易くするために軽量化することが求められている。そのため、掃除機本体は、近年、薄肉に形成されるようになってきている。
【0008】
また、掃除機本体の集塵室は、底壁とこの底壁から立ち上がって形成される周壁とから凹状に区画され、集塵容積を確保するために上記周壁の高さが高い。これに対し、蓋部を開閉する際の取扱性等の観点から、この蓋部の周壁の高さは低い。
【0009】
これらの事情から、集塵室を区画する周壁は蓋部の周壁よりも変形が生じやすく、電動送風機を駆動させて集塵室を負圧状態にすると、集塵室を区画する周壁が変形して、蓋部の位置とシール材の位置とがずれてしまうおそれがある。このずれが発生すると、蓋部と集塵室の開口部との間から集塵室内に空気が入り込んで負圧が低下し、これに伴い吸込み口体からの集塵の吸引力が低下してしまうものである。
【0010】
本発明が解決しようとする課題は、集塵室を区画する周壁の薄肉化を確保しつつ、負圧による前記周壁の変形を抑制できる電気掃除機を得ることにある。
【0011】
【課題を解決するための手段】
前記課題を解決するために、請求項1に係る発明の電気掃除機は、掃除機本体の集塵室の開口部を開閉する蓋部に、この蓋部が集塵室の開口部を閉じた状態で集塵室内に入り込んで開口部を内側から支える開口部支えが設けられている。
【0012】
この発明の電気掃除機によれば、蓋部に設けられた開口部支えが、この蓋部で集塵室の開口部を閉じることにより集塵室内に入り込んで開口部を内側から支えるため、集塵室を区画する周壁の負圧による変形が抑制される。
【0013】
【発明の実施の形態】
以下、図1〜図5を参照して本発明の一実施形態を説明する。
【0014】
電気掃除機1は、例えばキャニスタ型の電気掃除機1であり、図1に示すように、掃除機本体2、吸込み口体4、延長管7及び吸塵ホース5を備えている。
【0015】
掃除機本体2は、掃除機本体主部2a、及び、蓋部2b等を備えている。掃除機本体主部2aは、例えばポリプロピレン等により形成されている。掃除機本体主部2aの内部には、電源コードを巻取り及び繰出し可能なコードリール(図示せず)が収容されている。
【0016】
掃除機本体主部2aの外部両側面には、図1〜図3に示すように、後端側に配置されて一対の移動車輪10が枢支されている。この移動車輪10及び掃除機本体主部2aの下面に取付けられた旋回輪11(図3参照)により、掃除機本体2は床面上を自在に移動できる。掃除機本体主部2aには、その前端面に開口される吸塵口部12が設けられている。
【0017】
掃除機本体主部2aの内部には、図3に示すように、送風室13、及び、この送風室13の吸込み上流側に配置されて、一端面、例えば上端面に開口部15aが設けられた集塵室15を有している。送風室13には電動送風機14が収容されている。集塵室15は、底壁30とこの底壁30aから立ち上がって形成される周壁30bとにより形成される本体壁30から凹状に区画される。この凹状に区画された集塵室15には、開口部15aから出し入れ可能な集塵フィルタ17が取付け部15bに取付けられた状態で収容されている。また、集塵室15には、開口部15aの縁に沿ってリップ部を有するシール材16が設けられている。
【0018】
蓋部2bは、例えば、ABS樹脂により形成されている。この蓋部2bには、図5等に示すように、掃除機本体主部2aの吸込み下流側の一端部、例えば後端部に対応させて一対の脚部22が一体に形成されている。一対の脚部22には夫々突起22aが設けられており、これら突起22aを掃除機本体主部2aに形成された一対の孔部19に夫々嵌合させることで、蓋部2bは、図3に二点鎖線で示すように集塵室15の開口部15aを開く開き位置と、図2に実線で示すように集塵室15の開口部15aを閉じる閉じ位置とにわたって回動自在となるように、掃除機本体主部2aに取付けられている。
【0019】
蓋部2bには、集塵室15の開口部15aの縁に対応させて、内壁面から略垂直に立ち上がる周壁23が設けられている。周壁23は、集塵室15を区画する周壁30bよりも高さが低い。この周壁23は、蓋部2bにより集塵室15の開口部15aを閉じることでシール材16に押し当たるようにその高さが設定されている。
【0020】
さらに、この蓋部2bには、この蓋部2bが集塵室15の開口部15aを閉じた状態で集塵室15内に入り込んで開口部15aを内側から支える開口部支え21が設けられている。開口部支え21は、例えば、周壁23により囲まれた内側の領域に、蓋部2bの内壁面から略垂直に立ち上がるように形成された少なくとも1つ、好ましくは複数のリブとすることができる。この電気掃除機1では、図2〜図5に示すように、開口部支え21として前記リブを2つ設けている。以下、開口部支え21をリブと言う。
【0021】
これらリブ21は、図4に示すように、蓋部2bが集塵室15の開口部15aを閉じた状態で集塵室15内に入り込むようにその高さが設定されている。すなわち、これらリブ21の高さは、周壁23の高さよりも高く設定されている。また、これらリブ21は、電動送風機14によって集塵室15内に流通する空気の流れ方向に延びるように設けるのが好ましく、このようにすることにより、集塵室15内に流通する空気の妨げとなり難い。
【0022】
この電気掃除機1では、蓋部2bの前端部に係合部20が設けられているとともに、掃除機本体主部2aの前端部に蓋部2bの係合部20と係合する係合受け部18が設けられている(図4参照)。そして、蓋部2bを閉じ位置として、係合部20を掃除機本体主部2aの係合受け部18に係合させることにより、掃除機本体主部2aと蓋部2bとをシール材16を介して密着させて、集塵室15を気密状態に保持できるように形成されている。
【0023】
なお、集塵フィルタ17を取り替える際等、蓋部2bを開き位置とする場合は、指掛け部24に指を掛けて、蓋部2bを内側に押しながら上方に持ち上げることで、係合部20と係合受け部18との係合を解除することができる。
【0024】
吸込み口体4は、その下面に塵埃を取込む集塵開口(図示せず)を有している。この吸込み口体4には、集塵開口に臨む回転清掃体と、回転清掃体を回転駆動する清掃体モータとが夫々内蔵されているが、これらは省略してもよい。
【0025】
吸塵ホース5及び延長管7は、掃除機本体2と吸込み口体4とを連通するために用いられるものである。吸塵ホース5は可撓性ホースからなり、その吸込み上流側の一端部には各種の手元操作部6aを有するハンドル6が設けられている。延長管7は、硬質な複数の管8a,8bを伸縮可能に組み合わせて形成されている。吸塵ホース5及び延長管7には、夫々その長手方向に沿う図示しない電線が配線されている。なお、この電線は吸塵ホース5の伸縮及び可撓性を妨げない。
【0026】
この電気掃除機1は、図1に示すように、掃除機本体2の吸塵口部12に可撓性ホースからなる吸塵ホース5の一端部を連結し、この吸塵ホース5の他端部に硬質な延長管7の一端部を連結し、この延長管7の他端部に吸込み口体4を連結して使用する。
【0027】
前記構成を備える電気掃除機1を用いて被清掃面を清掃する場合、以下のようにして行なう。
【0028】
掃除機本体2から電源コードを引き出して商用交流電源に接続し、電動送風機14、ハンドル6の手元操作部6a、及び吸込み口体4の回転清掃体を回転駆動する清掃体モータ等に夫々電力を供給する。その後、手元操作部6aを操作して電動送風機14を駆動させる。
【0029】
電動送風機14が駆動すると、この電気送風機に吸込まれる気流が形成される。ハンドル6を操作して吸込み口体4を被清掃面に接触させ、吸込み口体4の集塵開口から被清掃面上の塵を空気とともに取り込んで、それを延長管7及び吸塵ホース5で掃除機本体2の集塵室15に導き、この集塵室15内の集塵フィルタ17で塵埃を捕捉する。集塵室15の集塵フィルタ17を通過した空気は、電動送風機14に吸込まれてこの送風機から排出された後、掃除機本体2に設けられた排気口(図示せず)を通して掃除機本体2の外部に排出される。回転清掃体は、電動送風機14の駆動中に手元操作部6aを操作することで適宜動作させることができる。以上により被清掃面を掃除できる。
【0030】
また、電動送風機14の駆動中は、集塵室15内は負圧が高くなるが、この電気掃除機1では、蓋部2bに設けられたリブ21が、この蓋部2bで集塵室15の開口部15aを閉じることにより集塵室15内に入り込んで開口部15を内側から支えるため、蓋部2b自体の変形が抑止されるだけでなく、集塵室15を区画する周壁30b(図2及び図3参照)の変形もまた抑制される。
【0031】
したがって、この電気掃除機1では、電動送風機14の駆動中であっても、蓋部2bの位置とシール材16の位置とがずれ難く、掃除機本体主部2aと蓋部2bとがシール材16を介して密着して、集塵室15を気密状態に保つことができる。これにより、蓋部2bと集塵室15の開口部15aとの間から掃除機本体2の内部に空気が入り込むことによる負圧の低下、及び、これに伴う吸引力の低下を抑制することができる。また、蓋部2bの係合部20と掃除機本体主部2aの係合受け部18との係合が外れ難くなり、蓋部2bが不用意に開かれるのを抑制できる。
【0032】
上記のように、この電気掃除機1によれば、蓋部2bに設けられたリブ21が、この蓋部2bで集塵室15の開口部15aを閉じることにより集塵室15内に入り込んで開口部15aを内側から支えるため、集塵室15を区画する周壁30bの変形を抑制でき、これにより、集塵室15を区画する周壁30bの薄肉化を実現できる。
【0033】
また、互いに平行な複数のリブ21を、電動送風機14によって集塵室15内に流通する空気の流れ方向に延びるように設けるのが好ましく、これにより、リブ21が電動送風機14によって集塵室15内に流通する空気の妨げとなり難い。
【0034】
また、集塵室15内に流通する空気の流れ方向と直交する周壁30bには、吸塵口部12や送風室13と連通する連通口が設けられているため、集塵室15内に流通する空気の流れ方向と平行な周壁30bと比べて強度が弱い。互いに平行な複数のリブ21を電動送風機14によって集塵室15内に流通する空気の流れ方向に延びて設けることにより、集塵室15内に流通する空気の流れ方向と直交する周壁30bを支えることができ、集塵室15を区画する周壁30bの変形をさらに良好に抑制することができる。
【0035】
なお、この実施形態では、蓋部2bを掃除機本体主部2aの後端部に回動自在に取付けることにより、掃除機本体主部2a全体を被う蓋部2bを設けているが、蓋部2bは、掃除機本体主部2aの集塵室15の開口部15を被うものであればよい。したがって、蓋部2bは、掃除機本体主部2aの集塵室15の開口部15を被うように、掃除機本体主部2aの中間部に回動自在に取付けてもよい。また、蓋部2bは、掃除機本体主部2aの上側から集塵室15の開口部15を被うように嵌め込むものであってもよい。
【0036】
また、この実施形態では、開口部支えをリブとしたが、開口部支えはリブに限定されるものではない。開口部支えは、蓋部に設けられて、この蓋部が集塵室の開口部を閉じた状態で集塵室内に入り込んで開口部を内側から支える形状及び強度を有するものであればよい。
【0037】
この発明は、電動送風機を収容する送風室、この送風室の吸込み上流側に配置されて一端面に開口部が設けられた集塵室、及び、この集塵室の開口部を開閉する蓋部を有する掃除機本体を具備するものであれば、キャニスタ型の電気掃除機だけでなく、アップライト型或いはスティック型等、種々の形状の電気掃除機に適用することができる。
【0038】
【発明の効果】
本発明によれば、集塵室を区画する周壁の薄肉化を確保しつつ、負圧による前記周壁の変形を抑制できる電気掃除機が得られる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a vacuum cleaner such as a canister type vacuum cleaner.
[0002]
[Prior art]
The vacuum cleaner includes, for example, a cleaner main body having a main body of the cleaner and a lid, and an opening of the dust collecting chamber of the main body of the cleaner is provided above the main body of the cleaner. Some parts open and close.
[0003]
The main part of the cleaner main body is formed of, for example, polypropylene or the like. Inside the main part of the main body of the cleaner, there is provided a blower chamber and a dust collecting chamber which is arranged on the upstream side of the suction of the blower chamber and has an opening at an upper end surface. An electric blower is housed in the blower room. The dust collection chamber houses a dust collection filter that can be taken in and out of the opening. Further, a sealing material is provided in the dust collecting chamber along the edge of the opening.
[0004]
The lid is formed of, for example, an ABS resin or the like. The lid is provided at the rear end of the main body of the cleaner so as to be rotatable between an open position for opening the opening of the dust collection chamber via a hinge fitting and a closed position for closing the opening. ing.
[0005]
In this vacuum cleaner, an engagement portion is provided at a front end portion of the lid portion, and an engagement receiving portion is provided at the front end portion of the main body of the cleaner to engage with the engagement portion of the lid portion. . Then, by closing the lid and engaging the engaging portion with the engagement receiving portion of the main body of the cleaner main body, the lid and the main body of the cleaner main body are brought into close contact with each other via a sealing material, and the dust collecting chamber is formed. Is formed so as to be able to be maintained in an airtight state.
[0006]
In this vacuum cleaner, one end of a dust suction hose made of a flexible hose is connected to the cleaner body, one end of a hard extension pipe is connected to the other end of the dust suction hose, and the other end of the extension pipe is connected. Use by connecting the suction port body to the part. Then, by the airflow formed by the electric blower, the dust is sucked together with the air from the suction opening body and guided to the dust collecting chamber of the cleaner body by the dust suction hose and the extension pipe, so that the dust is filtered by the dust collecting filter in the dust collecting chamber. Capture. The air that has passed through the dust collection filter of the dust collection chamber is discharged outside the cleaner body.
[0007]
[Problems to be solved by the invention]
By the way, the vacuum cleaner is required to be reduced in weight for easy handling. Therefore, the vacuum cleaner main body has recently been formed to be thin.
[0008]
In addition, the dust collecting chamber of the cleaner body is divided into a concave shape from a bottom wall and a peripheral wall rising from the bottom wall, and the height of the peripheral wall is high in order to secure a dust collecting volume. On the other hand, the height of the peripheral wall of the lid is low from the viewpoint of handleability when opening and closing the lid.
[0009]
For these reasons, the peripheral wall defining the dust collection chamber is more likely to be deformed than the peripheral wall of the lid, and when the electric blower is driven to bring the dust collection chamber into a negative pressure state, the peripheral wall defining the dust collection chamber is deformed. Therefore, there is a possibility that the position of the lid portion and the position of the sealing material are shifted. When this displacement occurs, air enters the dust collection chamber from between the lid and the opening of the dust collection chamber, and the negative pressure decreases, and accordingly, the suction force of the dust collection from the suction port body decreases. It is a mess.
[0010]
The problem to be solved by the present invention is to provide a vacuum cleaner capable of suppressing the deformation of the peripheral wall due to negative pressure while securing the thickness of the peripheral wall defining the dust collection chamber.
[0011]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, in the vacuum cleaner according to the first aspect of the present invention, a lid that opens and closes an opening of a dust collection chamber of a vacuum cleaner main body closes an opening of the dust collection chamber. An opening support is provided to enter the dust collection chamber in the state and support the opening from the inside.
[0012]
According to the vacuum cleaner of the present invention, since the opening support provided on the lid closes the opening of the dust collecting chamber with the lid and enters the dust collecting chamber to support the opening from the inside, Deformation due to the negative pressure of the peripheral wall defining the dust chamber is suppressed.
[0013]

An unillustrated electric wire is routed along the longitudinal direction of the dust suction hose 5 and the extension pipe 7, respectively. This electric wire does not hinder the expansion and contraction and flexibility of the dust suction hose 5.
[0026]
In this vacuum cleaner 1, as shown in FIG. 1, one end of a dust suction hose 5 composed of a flexible hose is connected to a dust suction port 12 of the cleaner body 2, and the other end of the dust suction hose 5 is connected to a hard end. One end of the extension pipe 7 is connected, and the suction port 4 is connected to the other end of the extension pipe 7 for use.
[0027]
When the surface to be cleaned is cleaned using the vacuum cleaner 1 having the above configuration, the cleaning is performed as follows.
[0028]
The power cord is pulled out from the cleaner main body 2 and connected to a commercial AC power supply, and the electric power is supplied to the electric blower 14, the hand operating portion 6a of the handle 6, the cleaning body motor for rotatingly driving the rotary cleaning body of the suction port body 4, and the like. Supply. Thereafter, the electric blower 14 is driven by operating the hand operation unit 6a.
[0029]
When the electric blower 14 is driven, an airflow sucked into the electric blower is formed. The suction port 4 is brought into contact with the surface to be cleaned by operating the handle 6, and the dust on the surface to be cleaned is taken in together with air from the dust collection opening of the suction port 4, and the dust is cleaned by the extension pipe 7 and the dust suction hose 5. The dust is guided to the dust collection chamber 15 of the machine main body 2, and dust is captured by the dust collection filter 17 in the dust collection chamber 15. The air that has passed through the dust collecting filter 17 of the dust collecting chamber 15 is drawn into the electric blower 14 and discharged from the blower, and then passes through an exhaust port (not shown) provided in the cleaner main body 2. Is discharged to the outside. The rotating cleaning body can be appropriately operated by operating the hand operation unit 6a while the electric blower 14 is being driven. Thus, the surface to be cleaned can be cleaned.
[0030]
While the electric blower 14 is driven, the negative pressure inside the dust collecting chamber 15 increases. However, in the vacuum cleaner 1, the ribs 21 provided on the lid 2b are separated from the dust collecting chamber 15 by the lid 2b. By closing the opening 15a, the dust enters the dust collecting chamber 15 and supports the opening 15 from the inside, so that not only the deformation of the lid 2b itself is suppressed, but also the peripheral wall 30b (see FIG. 2 and FIG. 3) are also suppressed.
[0031]
Therefore, in the electric vacuum cleaner 1, even when the electric blower 14 is being driven, the position of the lid 2b and the position of the sealing material 16 are unlikely to be displaced, and the main body 2a of the cleaner main body and the lid 2b are separated by the sealing material. The dust collecting chamber 15 can be kept in an airtight state by being in close contact with the dust collecting chamber 16. Thereby, it is possible to suppress a decrease in negative pressure due to air entering into the inside of the cleaner body 2 from between the lid 2b and the opening 15a of the dust collection chamber 15, and a reduction in suction force due to this. it can. In addition, the engagement between the engagement portion 20 of the lid 2b and the engagement receiving portion 18 of the main body 2a of the cleaner becomes difficult to separate, and it is possible to prevent the lid 2b from being opened carelessly.
[0032]
As described above, according to this vacuum cleaner 1, the rib 21 provided on the lid 2b enters the dust collecting chamber 15 by closing the opening 15a of the dust collecting chamber 15 with the lid 2b. Since the opening 15a is supported from the inside, the deformation of the peripheral wall 30b that divides the dust collecting chamber 15 can be suppressed, and the thickness of the peripheral wall 30b that divides the dust collecting chamber 15 can be reduced.
[0033]
Further, it is preferable that a plurality of ribs 21 parallel to each other be provided so as to extend in the flow direction of the air flowing into the dust collecting chamber 15 by the electric blower 14, whereby the ribs 21 are moved by the electric blower 14 to the dust collecting chamber 15. It is hard to hinder the air flowing inside.
[0034]
The peripheral wall 30 b orthogonal to the flow direction of the air flowing through the dust collecting chamber 15 is provided with a communication port that communicates with the dust suction port 12 and the blower chamber 13, and thus flows through the dust collecting chamber 15. The strength is lower than that of the peripheral wall 30b that is parallel to the air flow direction. By providing a plurality of parallel ribs 21 in the direction of flow of the air flowing through the dust collecting chamber 15 by the electric blower 14, the ribs 21 support the peripheral wall 30 b orthogonal to the direction of the flow of the air flowing through the dust collecting chamber 15. Therefore, the deformation of the peripheral wall 30b that divides the dust collection chamber 15 can be more favorably suppressed.
[0035]
In this embodiment, the lid 2b is provided rotatably on the rear end of the main body 2a of the cleaner to cover the entire main body 2a of the cleaner, but the lid 2b is provided. The portion 2b may cover the opening 15 of the dust collecting chamber 15 of the main body 2a of the cleaner. Therefore, the lid 2b may be rotatably attached to the intermediate portion of the cleaner main body 2a so as to cover the opening 15 of the dust collecting chamber 15 of the cleaner main body 2a. The lid 2b may be fitted so as to cover the opening 15 of the dust collecting chamber 15 from above the cleaner main body 2a.
[0036]
In this embodiment, the opening support is a rib, but the opening support is not limited to the rib. The opening support may be provided on the lid, and may have any shape and strength so that the lid enters the dust collection chamber with the opening of the dust collection chamber closed and supports the opening from the inside.
[0037]
The present invention relates to a blower chamber for accommodating an electric blower, a dust collecting chamber arranged upstream of the suction of the blower chamber and having an opening at one end surface, and a lid for opening and closing the opening of the dust collecting chamber. The present invention can be applied not only to a canister-type vacuum cleaner but also to vacuum cleaners of various shapes, such as an upright type or a stick type, as long as it has a vacuum cleaner body having the following.
[0038]
