【考案の詳細な説明】 本考案は電気掃除機の排気切換用等に用いられる弁体の
取付構造に関するものである。[Detailed Description of the Invention] The present invention relates to a mounting structure for a valve body used for switching the exhaust of a vacuum cleaner.

従来、電気掃除機の弁装置にあって、その弁体の取付け
は、第７図のように弁体１０１に挿通した軸１０２の両
端を掃除機本体１０３に形成したボス部１０４にビス１
０５で固定したものとか、第８図のように掃除機本体１
０３より突設したリブ１０６の溝１０７に軸１０２の両
側部を圧入するとともに、同軸１０２の各端部に対向し
てその長手方向の動きを阻止するリブ１０８を形成した
もの等があった。Conventionally, in the valve device of a vacuum cleaner, the valve body is installed by attaching both ends of a shaft 102 inserted through the valve body 101 to a boss portion 104 formed in the vacuum cleaner body 103 with screws 1, as shown in FIG.
05, or the vacuum cleaner body 1 as shown in Figure 8.
There was one in which both sides of the shaft 102 were press-fitted into grooves 107 of a rib 106 protruding from the shaft 103, and ribs 108 were formed opposite each end of the shaft 102 to prevent movement in the longitudinal direction.

しかし、前者のものではビス止め作業が必要で取着に手
間がかかり、また後者のものでは軸圧入時にリブ１０６
が破損する欠侭があった。However, the former requires screws and is time-consuming to install, and the latter requires the rib 106 when press-fitting the shaft.
There was a defect that caused damage.

本考案はこのような従来の欠点を解消したもので、弁体
の取付けを簡単な構成により容易に行うことを目的とす
るものである。The present invention eliminates these conventional drawbacks and aims to facilitate the installation of a valve body with a simple structure.

上記目的達成のため上記の電気掃除機の弁体取付構造は
、弁体の取付部に挿通した軸を略り字状に形成するとと
もに、その一端には折曲部を設け、この軸は電気掃除機
の本体に形成した引っ掛は部に一端折曲部を引っ掛け、
他端は同じく本体に設けたリブに圧接して突張り状態に
取着したものである。In order to achieve the above purpose, the valve body mounting structure of the vacuum cleaner is such that the shaft inserted through the valve body mounting part is formed into an abbreviated shape, and a bent part is provided at one end, and this shaft is connected to the electric The hook formed on the main body of the vacuum cleaner hooks the bent part at one end,
The other end is similarly attached to a rib provided on the main body under pressure and in a tensioned state.

したがって、弁体の取付けは、軸の一方をリブに圧接さ
せて次いで他方の折曲部を引っ掛は部に引っ掛けること
で容易にできるものである。Therefore, the valve body can be easily attached by pressing one of the shafts against the ribs and then hooking the bent portion of the other shaft onto the rib.

以下その実施例を添附図面とともに説明する。Examples thereof will be described below with reference to the accompanying drawings.

第１図〜第６図において、１は電動送風機２、集塵袋３
、付属部品４を内装した掃除機の本体、５は集塵室６を
閉塞する集塵蓋で、尾錠７により本体１に係止自在とな
っている。In Figures 1 to 6, 1 is an electric blower 2, a dust collection bag 3
, a main body of the vacuum cleaner which includes attached parts 4; 5 is a dust collection lid that closes a dust collection chamber 6, and can be freely locked to the main body 1 with a buckle 7.

８は付属部品収納室９を閉塞する蓋体で、本体１に回動
自在に取付けられる。A lid 8 closes the accessory storage chamber 9 and is rotatably attached to the main body 1.

１０は本体１とで電動送風機２の収納室を形成する底板
、１１は同じく本体上である。Numeral 10 is a bottom plate which together with the main body 1 forms a storage chamber for the electric blower 2, and 11 is also on the main body.

また、１２は集中排気口１３を常閉する弁体、１４はこ
の弁体１２の回転中心となる略り字状の軸、１５は弁体
１２を常閉する方向に附勢するばねである。Further, 12 is a valve body that normally closes the central exhaust port 13, 14 is an abbreviated shaft that is the center of rotation of this valve body 12, and 15 is a spring that biases the valve body 12 in the direction of normally closing it. .

また１６．１７は掃除機の移動を容易にする車輪である
。Also, 16 and 17 are wheels that make it easier to move the vacuum cleaner.

上記の構成よりなる掃除機を運転すると、塵を含んだ空
気は本体１の前面に設けられた吸込口１８から吸込まれ
る。When the vacuum cleaner configured as described above is operated, air containing dust is sucked in through the suction port 18 provided on the front surface of the main body 1.

そして集塵室６を通過する際に塵は集塵袋３内に取残さ
れ、また濾過された空気は集塵室６と電動送風機２の前
部を連通する連通口１９から電動送風機２内へ、さらに
排気通路を通り分散排気口２０より外気に吐出する。When passing through the dust collection chamber 6, the dust is left behind in the dust collection bag 3, and the filtered air enters the electric blower 2 through the communication port 19 that communicates the dust collection chamber 6 with the front part of the electric blower 2. Then, it passes through an exhaust passage and is discharged to the outside air from a distributed exhaust port 20.

このように通常は本体１後壁に設けられた分散排気口２
０より空気は吐出される。In this way, normally the distributed exhaust port 2 is provided on the rear wall of the main body 1.
Air is discharged from 0.

この時、弁体１２はばね１５の付勢力により集中排気”
１１３を閉塞しているが、排気を利用したい場合は、第
３図に示すごとくパイプ２１を挿入することにより、弁
体１２が軸１４を中心として回動して、その上面が本体
１及び本体上１１のリブ２２，２３’に接触し、これを
空気タイトすることによって空気は分散排気口２０方向
には流れず、集中排気を利用できる。At this time, the valve body 12 is forced to concentrate exhaust by the biasing force of the spring 15.
113 is closed, but if you wish to use the exhaust, insert the pipe 21 as shown in FIG. By contacting the ribs 22, 23' of the upper part 11 and making them air tight, the air does not flow toward the distributed exhaust port 20, and centralized exhaust can be used.

次に、弁体１２の取付構成について述べる。Next, the mounting structure of the valve body 12 will be described.

略り字状をした軸１４の一端２２を弁体１２の回転中心
部の一方２３に通し、ばね１５を軸１４に通し、さらに
弁体１２の回転中心部の他方２４に通すことにより弁体
１２及びばね１５をセットした状態で、一端２２を本体
１のリブ２５に当接させてリブ２６と２７の間に挿入し
、軸１４の他端２８の折曲部２９を挿入穴３０に挿入固
定する。One end 22 of the abbreviated shaft 14 is passed through one 23 of the center of rotation of the valve body 12, and the spring 15 is passed through the shaft 14, and then passed through the other 24 of the center of rotation of the valve body 12. 12 and spring 15 are set, one end 22 is brought into contact with the rib 25 of the main body 1 and inserted between the ribs 26 and 27, and the bent part 29 of the other end 28 of the shaft 14 is inserted into the insertion hole 30. Fix it.

ここで軸１４は突張り状態に固定されるものである。Here, the shaft 14 is fixed in a tensioned state.

すなわち、第４図に示すように軸１４の曲げ角度ａを例
えば、直角より太き目に設定し、第５図、第６図で示す
ように軸１４の弾性を利用してその曲げ取付角度ａ１を
ほぼ直角に近い状態までたわませれば、復元力によつり
軸１４は突張り状態で固定されるものである。That is, as shown in FIG. 4, the bending angle a of the shaft 14 is set to be thicker than the right angle, for example, and the bending angle a is adjusted using the elasticity of the shaft 14 as shown in FIGS. 5 and 6. When a1 is bent to a nearly right angle position, the suspension shaft 14 is fixed in tension due to the restoring force.

このような弁体１２の取付構造であると、弁体１２、こ
れを支持する軸１４及び弁体１２を附勢するばね１５の
最低限の部品で特に他の部品を必要とせず価格を安くで
きるとともに、軸１４を本体１にセットするだけで弁体
１２の取着ができ、組立てが容易にできる。With such a mounting structure for the valve body 12, the price can be reduced by using the minimum parts of the valve body 12, the shaft 14 that supports it, and the spring 15 that biases the valve body 12, and does not require any other parts. In addition, the valve body 12 can be attached simply by setting the shaft 14 to the main body 1, making assembly easy.

また、弁体１２の取付箇所が深い所であっても軸１４の
他端２８を長く取るようにすれば組立ても難しくなく、
深い箇所への取付けにも適している。Furthermore, even if the valve body 12 is installed in a deep place, assembly is not difficult if the other end 28 of the shaft 14 is made long.
Also suitable for installation in deep locations.

さらに、軸１４をセットした後は、軸１４の弾性力及び
一端２２とリブ２５の接触により容易にはずれにくくな
り、しかも軸１４の仕上り寸法のばらつきに関し、長く
なる方のばらつきに設定しておけば、第６図のように軸
１４の途中がたわんでそのばらつきを吸収できるもので
ある。Furthermore, after the shaft 14 is set, it will not easily come off due to the elastic force of the shaft 14 and the contact between the one end 22 and the rib 25, and in addition, regarding the variation in the finished dimensions of the shaft 14, it is recommended to set the variation in the longer direction. For example, as shown in FIG. 6, the shaft 14 is bent in the middle so that variations in the bending can be absorbed.

上記構成のような本考案の電気掃除機の弁体取付構成に
よれば、弁体の取付及び構造が簡単で、部品点数の少な
い安価な製品を提供することができるとともに、取付部
の破損も防止できるものである。According to the valve body mounting structure of the vacuum cleaner of the present invention as described above, the installation and structure of the valve body are simple, it is possible to provide an inexpensive product with a small number of parts, and there is no damage to the mounting part. It is preventable.

特に軸を略り字状としたので、弁体取付部が掃除機本体
の奥深いところにあっても容易に取付作業ができ、きわ
めて勝手がよい。In particular, since the shaft is shaped like an abbreviated letter, even if the valve body mounting portion is located deep within the vacuum cleaner body, the mounting work can be done easily, which is extremely convenient.
