【考案の詳細な説明】 産業上の利用分野 本考案は真空掃除機に関するものである。[Detailed explanation of the idea] Industrial applications The present invention relates to a vacuum cleaner.
従来の技術
実開昭53−166560号公報などに示される従来の
真空掃除機の構成は概略的には第１図のようにな
つていた。Prior Art The structure of a conventional vacuum cleaner disclosed in Japanese Utility Model Application Publication No. 53-166560 and the like is schematically shown in FIG.
すなわち、第１図において、１はフアンモータ
などを内蔵した掃除機主体の吸引側に着脱自在に
設けたダストボツクスで、略垂直方向のフイルタ
ー２とこれに対応してダストボツクス１の前方に
形成した吸気口３とを有し、かつこれらフイルタ
ー２と吸気口３との間は集塵室４としてある。５

の塵埃が吸気口３を介して外部に出るのを防止す
る逆止弁で、集塵室４内に臨ませて設けてある。
そのてこの逆止弁５の開閉支点は上方に設定して
ある。 That is, in FIG. 1, 1 is a dust box removably installed on the suction side of the main body of the vacuum cleaner, which has a built-in fan motor, etc., and is formed in front of the dust box 1 in correspondence with a substantially vertical filter 2. A dust collection chamber 4 is provided between the filter 2 and the intake port 3. 5
is a check valve that prevents dust in the dust collection chamber 4 from going out through the intake port 3 when the vacuum cleaner is stopped, and is provided facing the inside of the dust collection chamber 4.
The opening/closing fulcrum of the lever check valve 5 is set upward.
上記構成において、吸気口３より流入した含塵
空気はフイルター２に達し、一部はそれを通過
し、また他の一部は集塵室４内で旋回する。 In the above configuration, the dust-containing air flowing in through the intake port 3 reaches the filter 2, a part of which passes through it, and the other part swirls within the dust collection chamber 4.
考案が解決しようとする問題点
ところで、上記旋回流は逆止弁５に当つてそれ
を閉じようとする。したがつて、従来にあつては
逆止弁５によつて吸気口３の開口面積が実質的に
絞られるような形態となり、これより通気抵抗が
増大して集塵効率の低下をまねいていた。また一
部には吸気口に差込んだホース接続パイプの先端
で逆止弁を強制開放するものもあるが（例えば、
特開昭50−56752号公報、実開昭53−166560号公
報）、通常逆止弁はゴムなどの可撓材で形成され
ており、したがつて、この場合も上記と同様の問
題があつた。Problems to be solved by the invention By the way, the swirling flow hits the check valve 5 and tries to close it. Therefore, in the past, the opening area of the intake port 3 was substantially restricted by the check valve 5, which increased ventilation resistance and reduced dust collection efficiency. . In addition, there are some that forcibly open the check valve at the end of the hose connection pipe inserted into the intake port (for example,
(Japanese Unexamined Patent Publication No. 50-56752, Japanese Utility Model Application No. 53-166560), check valves are usually made of a flexible material such as rubber, and therefore, the same problem as above occurs in this case as well. Ta.
本考案はこのような従来の欠点を解消したもの
で、集塵効率の向上を図つたものである。 The present invention eliminates these conventional drawbacks and aims to improve dust collection efficiency.
問題点を解決するための手段
このような従来の問題点を解決するために本考
案は、ダストボツクスに略垂直平板状のフイルタ
ーおよびこのフイルターと対応して前方に吸気口
を設けるとともに、上記フイルター前方の集塵室
内に臨ませて上記吸気口に開閉支点部を上方に設
定した弁を配設し、さらに上記逆止弁の上方に集
塵室の内側へ突出し、かつ逆止弁の上方を覆う長
さをもつ水平方向の隔壁を形成したものである。Means for Solving the Problems In order to solve these conventional problems, the present invention provides a substantially vertical flat filter in the dust box, an intake port in front of the filter, and A valve with an opening/closing fulcrum set upward is provided at the intake port facing into the dust collection chamber at the front, and furthermore, a valve is provided above the check valve that protrudes into the dust collection chamber, and a valve above the check valve is provided. A horizontal partition wall with a length that covers the wall is formed.
作 用
上記本考案の構成において、集塵室内で旋回す
る空気でしかも、同集塵室の内部前方で下降する
ものは逆止弁に至る以前に隔壁で受止めされる。
したがつて、逆止弁は確実に開状態に保たれるも
のである。Effect: In the configuration of the present invention described above, the air swirling inside the dust collection chamber and falling at the front of the inside of the dust collection chamber is caught by the partition wall before reaching the check valve.
Therefore, the check valve is reliably kept open.
実施例 以下その実施例を第２図を参照して説明する。Example An embodiment thereof will be described below with reference to FIG.
なお、第２図において第１図と同一部分には便
宜上同一符号をつけ説明は省略した。 Note that in FIG. 2, the same parts as in FIG. 1 are given the same reference numerals for convenience, and their explanations are omitted.
すなわち、本考案は逆止弁５の上方に隔壁６を
設けたものである。上記隔壁６は集塵室４の一内
側壁から他内側壁の全巾に設けてあり、フイルタ
ー２および集塵室４の内頂壁に沿う旋回流のすべ
てを受止めるように構成してある。 That is, in the present invention, a partition wall 6 is provided above the check valve 5. The partition wall 6 is provided along the entire width of the dust collecting chamber 4 from one inner wall to the other inner wall, and is configured to receive all of the swirling flow along the filter 2 and the inner top wall of the dust collecting chamber 4. .
したがつて、逆止弁５の閉成方向に旋回流が作
用することなく、吸気口３の開口面積を最大限確
保できるものである。 Therefore, the opening area of the intake port 3 can be secured to the maximum extent without any swirling flow acting in the closing direction of the check valve 5.
また上記隔壁６によつて、旋回流形成領域は集
塵室４の上半分に限定されるため、フイルター２
の前面下方には綿ごみなどの塵埃が速やかにたま
ることとなる。すなわち、フイルター２の前面下
方には上記旋回流が作用しなくなるため、同部分
の塵埃はそのまま残つて吹き飛ばされるようなこ
とがなくなるものである。よつて、上記塵埃は凝
フイルター層２′を形成し、特に細塵に対する
過性を良好とするものである。 Furthermore, the partition wall 6 limits the swirling flow forming area to the upper half of the dust collection chamber 4, so the filter 2
Dust such as cotton waste quickly accumulates below the front surface of the machine. That is, since the swirling flow no longer acts on the lower front surface of the filter 2, the dust in this area remains as it is and is not blown away. Therefore, the above-mentioned dust forms a fine filter layer 2', which has particularly good resistance to fine dust.
考案の効果
以上のように本考案によれば通気抵抗の減少お
よび塵埃による凝フイルター層の形成によつて従
来に比し集塵効率を著しく高め得るものである。Effects of the Invention As described above, according to the present invention, the dust collection efficiency can be significantly improved compared to the conventional method by reducing ventilation resistance and forming a filter layer made of dust.
ちなみに第３図は従来製品Ｂと本考案製品Ａと
の集塵効率比較であり、これより、上記本考案の
効果が確認できるであろう。 Incidentally, FIG. 3 is a comparison of dust collection efficiency between conventional product B and product A of the present invention, and from this, the effects of the above-mentioned present invention can be confirmed.
