Description

本発明は、電気掃除機に係り、より詳しくは、清掃作業終了後のスタンド収納時に、延長管などの吸込手段を掃除機本体に保持することができる電気掃除機に関する。 The present invention relates to a vacuum cleaner, and more particularly to a vacuum cleaner that can hold suction means such as an extension pipe in a vacuum cleaner body when the stand is stored after the completion of the cleaning operation.

従来の電機掃除機は、清掃作業終了後に、掃除機本体を起立したスタンド状態にして床面に設置する。そして、掃除機本体に接続したままのホ−ス、延長管、床ブラシなどの吸込手段を掃除機本体に沿って垂直方向に結合して保管している。 In the conventional electric vacuum cleaner, after the cleaning work is finished, the vacuum cleaner main body is placed in a standing state and installed on the floor. And suction means, such as a hose, an extension pipe, and a floor brush, which are still connected to the vacuum cleaner main body, are vertically coupled along the vacuum cleaner main body and stored.

このとき、延長管に設けたフックを、掃除機本体の底面に設けた１個の前車輪の前側もしくは左右のいずれかの側に設けたフック固定穴、あるいは別部品により構成するスタンドホルダーに装着する。この際、床ブラシが床面に接触する状態になるようにフックの位置を調整し、あるいはパイプの長さや床ブラシ接続部の長さを調整して、スタンド収納時の転倒を防止するようにしている（例えば、特許文献１参照）。 At this time, the hook provided on the extension pipe is mounted on the hook fixing hole provided on the front side or the left or right side of one front wheel provided on the bottom surface of the cleaner body, or on a stand holder constituted by another part. To do. At this time, adjust the position of the hook so that the floor brush comes into contact with the floor surface, or adjust the length of the pipe and the floor brush connection part to prevent the stand from falling when the stand is stored. (For example, refer to Patent Document 1).

特開２００６−２５５３０５号公報（第４−５頁、図１）JP 2006-255305 A (page 4-5, FIG. 1)

特許文献１記載の電気掃除機においては、フック固定穴の上下位置の調整は前車輪が干渉するためこれに規制されて調整範囲が狭く、また、左右方向に位置調整をするとスタンド収納時の掃除機本体のバランスが悪くなって転倒するおそれがある。さらに、延長管や床ブラシによって長さ調整を行う場合は別部品を追加しなければならず、あるいは長くなるために梱包形態が大きくなってしまうという問題があった。 In the electric vacuum cleaner described in Patent Document 1, the adjustment of the vertical position of the hook fixing hole is restricted by the front wheel because of interference, and the adjustment range is narrow. There is a risk of the machine body becoming unbalanced and falling. Furthermore, when the length is adjusted with an extension pipe or a floor brush, another part must be added, or the packaging form becomes large due to the increase in length.

本発明は、上記のような課題を解決するためになされたもので、非清掃時において、前車輪の位置に規制されることなく吸込手段を掃除機本体に容易かつ確実に係止してスタンド収納することができる電気掃除機を得ることを目的とする。 The present invention has been made in order to solve the above-described problems, and in the non-cleaning state, the suction means is easily and reliably locked to the cleaner body without being restricted by the position of the front wheel. It aims at obtaining the vacuum cleaner which can be accommodated.

本発明に係る電気掃除機は、内部に集塵室や電動送風機が設けられ、底部の前部側に一対の前車輪が設けられ後部両側には一対の後車輪が設けられて前部側に吸込手段が接続され、非清掃時に吸込手段に設けたフックを底部に設けたフック係止部に係止してスタンド状態にする掃除機本体を備え、フック係止部を、一対の前車輪の間に設けたものである。 The vacuum cleaner according to the present invention includes a dust collection chamber and an electric blower inside, a pair of front wheels on the front side of the bottom, a pair of rear wheels on both sides of the rear, and a front side. A vacuum cleaner body is connected to the suction means, and the hook provided on the suction means is locked to the hook locking portion provided on the bottom when not being cleaned, so that the hook locking portion is connected to the pair of front wheels. It is provided in between.

前車輪に規制されることなく、フック係止部の位置を自由に設定することができるので、清掃作業後のスタンド収納時において、吸込手段の着脱性の向上を図ることができる。また、スタンド収納時に吸込手段の長さ調整を行う必要がなく、製品の減量化、製品包装の減量化が可能となる。さらに、前車輪が一対設けられているので、清掃作業時においても走行安定性を向上させることができる。 Since the position of the hook engaging portion can be freely set without being restricted by the front wheel, the detachability of the suction means can be improved when the stand is stored after the cleaning operation. In addition, it is not necessary to adjust the length of the suction means when the stand is stored, and the product can be reduced and the product packaging can be reduced. Furthermore, since a pair of front wheels are provided, traveling stability can be improved even during cleaning work.

次に、上記のように構成した本発明に係る電気掃除機の作用を説明する。
まず、掃除機本体１に設けた電源コード（図示せず）を商用電源に接続し、床ブラシ１３を床面上に位置させて、ホース１０の手元ハンドル１１に設けた電源スイッチをＯＮにする。これにより、掃除機本体１内に設けた電動送風機が駆動され、その吸引力によって塵埃等を含む空気が床ブラシ１３から吸引される。 Next, the operation of the vacuum cleaner according to the present invention configured as described above will be described.
First, a power cord (not shown) provided on the vacuum cleaner main body 1 is connected to a commercial power source, the floor brush 13 is positioned on the floor surface, and a power switch provided on the hand handle 11 of the hose 10 is turned ON. . Thereby, the electric blower provided in the cleaner body 1 is driven, and air including dust and the like is sucked from the floor brush 13 by the suction force.

こうして、床ブラシ１３から吸い込まれた塵埃等を含む空気流は、延長管１２、ホース１０を経て掃除機本体１内の集塵室に送られ、塵埃等と空気等に分離される。分離された塵埃等は集塵室内に補足されて堆積し、空気はフィルタによって清掃化され、電動送風機等を冷却したのち、後部等に設けた排気口から外部へ排出される。 In this way, the air flow including dust and the like sucked from the floor brush 13 is sent to the dust collection chamber in the cleaner body 1 through the extension pipe 12 and the hose 10, and is separated into dust and air. The separated dust or the like is trapped and accumulated in the dust collection chamber, and the air is cleaned by a filter, and after cooling the electric blower or the like, it is discharged to the outside from an exhaust port provided in the rear portion or the like.

このとき、掃除機本体１の下ケース底面３及びこれから突設された前車輪外周突部６は、床面から一定の距離だけ離れて空間部が形成されるような高さになっているので、障害物を乗り越える際に引掛ることがなく、安定して走行することができる。 At this time, the lower case bottom surface 3 of the vacuum cleaner main body 1 and the front wheel outer peripheral protrusion 6 protruding therefrom are so high that a space is formed at a certain distance from the floor surface. It is possible to travel stably without getting caught when getting over obstacles.

掃除が終わったときは、掃除機本体１を起立させて、図１、図２に示すように、スタンド収納状態とする。そして、延長管１２に取り付けたフック１４を、掃除機本体１の下ケース底面３に設けたガイド溝８の挿入口８ａからガイド面８ｂに沿って下降させ、図５に示すように、フック係止部９に係止させて固定する。
こうして、図１および図２に示すように、延長管１２は電気掃除機の掃除機本体１に固定され、吸込手段は掃除機本体１の垂直方向に保持される。 When the cleaning is finished, the vacuum cleaner body 1 is erected and the stand is stored as shown in FIGS. Then, the hook 14 attached to the extension pipe 12 is lowered along the guide surface 8b from the insertion port 8a of the guide groove 8 provided in the lower case bottom surface 3 of the cleaner body 1, and as shown in FIG. The stopper 9 is locked and fixed.
Thus, as shown in FIGS. 1 and 2, the extension pipe 12 is fixed to the vacuum cleaner main body 1 of the electric vacuum cleaner, and the suction means is held in the vertical direction of the vacuum cleaner main body 1.

本発明に係る電気掃除機によれば、前車輪５の位置に規制されることなく、フック係止部９の位置を自由に設定することができるので、清掃作業後のスタンド収納時において、延長管１２の着脱性を向上することができる。また、前車輪５が一対設けられ、しかも前車輪外周突部６の底面６ａと床面との間に空間部が設けられているので、清掃作業時においても走行安定性を向上させることができる。 According to the vacuum cleaner according to the present invention, the position of the hook locking portion 9 can be freely set without being restricted by the position of the front wheel 5, so that it is extended when the stand is stored after the cleaning work. The detachability of the tube 12 can be improved. Further, since a pair of front wheels 5 are provided and a space is provided between the bottom surface 6a of the front wheel outer peripheral projection 6 and the floor surface, the running stability can be improved even during cleaning work. .
