産業上の利用分野
本発明は電気掃除機のホース・延長管に接続して用いる
タービンノズルに関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a turbine nozzle connected to a hose/extension pipe of a vacuum cleaner.
従来の技術
従来、この種のタービンノズルにおいては、電気掃除機
の吸引空気流でタービンノズル内に配置したタービン車
を回転させ、発生した回転トルクで、ブラシ毛を外周面
に植設した回転ブラシを回転駆動し、じゅうたん等の繊
維根元の塵埃を掻き上げ・吸入して吸塵性能を高めて使
用する構成となっていた。Conventional technology Conventionally, in this type of turbine nozzle, a turbine wheel placed in the turbine nozzle is rotated by the suction air flow of a vacuum cleaner, and the generated rotational torque is used to create a rotating brush with brush bristles planted on the outer peripheral surface. It was designed to be used by rotating and scraping up and sucking up dust from the base of the fibers of carpets, etc., to improve its dust absorption performance.
ところが、近年の電気掃除機の吸込１１能の向上にとも
ない、塵埃を収塵していないときの吸込風量（これを以
下初期風量と呼ぶ）が増大してきている。この結果、電
気掃除機の使い始めや、ゴミを捨てた後の使用時、或は
ある程度の塵埃が吸入されるまでは、初期風量或は初期
風量に近い数値の吸込風量でタービン車を超高速回転さ
せることとなり、タービン車及び回転ブラシの軸受構造
部の寿命低下、及びタービンノズルに衝突する吸込気流
をタービン車の羽根が断続的に、かつ高速で切るときに
発生する高周波音を原因とする騒音の増大という問題を
生じている。However, as the suction capacity of vacuum cleaners has improved in recent years, the suction air volume (hereinafter referred to as initial air volume) when dust is not collected has increased. As a result, when you start using a vacuum cleaner, when you use it after throwing away garbage, or until a certain amount of dust is inhaled, the turbine car is operated at ultra-high speed with the initial air volume or a suction air volume close to the initial air volume. This causes a reduction in the life of the bearing structure of the turbine wheel and rotating brush, as well as high-frequency noise generated when the blades of the turbine wheel intermittently cut the intake airflow that collides with the turbine nozzle at high speed. This has caused the problem of increased noise.
これを解消する一手段として、例えば、次のようなもの
が考えられている。すなわち、タービンノズルを空中に
浮かしたときは、じゅうたん上に接地しているときに比
べて吸気抵抗と回転ブラシの回転を阻害する摩擦抵抗が
減少し、その結果、タービン車や回転ブラシの回転が増
大して前述の問題が発生するため、空中に浮かしたとき
には、バイパス空気通路を形成してこの通路から空気を
吸わせることによってタービン車の回転に寄与する吸気
空気量を減少させ、タービン車・回転ブラシの回転数を
一時的に低下させて騒音の低下・寿命の延長を図るもの
である。For example, the following methods have been considered as a means to solve this problem. In other words, when the turbine nozzle is suspended in the air, compared to when it is grounded on a carpet, the intake resistance and the frictional resistance that inhibits the rotation of the rotating brushes are reduced, and as a result, the rotation of the turbine wheel and rotating brushes is reduced. This increases the number of problems described above, so when floating in the air, a bypass air passage is formed and air is sucked through this passage to reduce the amount of intake air that contributes to the rotation of the turbine wheel. This is intended to reduce noise and extend life by temporarily lowering the rotation speed of the rotating brush.
発明が解決しようとする課題
ところが上記構成のものでは、タービンノズルを空中に
浮かしたときのみタービン車及び回転ブラシの回転数が
低下する構成のため、同じタービンノズルをより性能の
高い電気掃除機に接続して使用すると、じゅうたん上で
使用しているときでも製品設計上許容できる以上の回転
数状態が生じ、再び！ＪＩ音の増大や耐久性−の低下を
招いてしまう。従って電気掃除機本体の吸込性能の向上
にともなって、その都度タービンノズルの性能・耐久性
の見直しを行なわなければならず、設計効率の面からも
問題となっていた。Problem to be Solved by the Invention However, with the above configuration, the rotational speed of the turbine wheel and rotating brush decreases only when the turbine nozzle is suspended in the air, so it is difficult to use the same turbine nozzle in a vacuum cleaner with higher performance. If you connect and use it, the rotation speed will be higher than the product design allows even when you are using it on a carpet, and it will happen again! This results in an increase in JI sound and a decrease in durability. Therefore, as the suction performance of the vacuum cleaner body improves, the performance and durability of the turbine nozzle must be reviewed each time, which also poses a problem in terms of design efficiency.
本発明はこの問題を解消し、使用性・耐久性に優れたタ
ービンノズルを提供しようとするものである。The present invention aims to solve this problem and provide a turbine nozzle with excellent usability and durability.
課題を解決するための手段
本発明は上記目的を達成するため、内部に回転ブラシを
収容し下面に吸込口を有する回転ブラシ室と、上記回転
ブラシを回転駆動するタービン車を内蔵するタービン室
と、上記タービン室と回転ブラシ室を連通ずる主・副通
路と、主通路を開閉する遮蔽板と、副通路に臨みこの副
通路を通過する吸込気流の流速に応じて副通路の開口面
積を変更する風速調節体とを設けるものである。Means for Solving the Problems In order to achieve the above objects, the present invention provides a rotating brush chamber that accommodates a rotating brush therein and has a suction port on its lower surface, and a turbine chamber that incorporates a turbine wheel that rotationally drives the rotating brush. , a main and sub passage that communicates the turbine chamber and the rotating brush chamber, a shielding plate that opens and closes the main passage, and an opening area of the sub passage that changes according to the flow velocity of the suction airflow that faces the sub passage and passes through the sub passage. A wind speed regulator is provided.
作用
この構成により、遮蔽板で主通路を閉塞して吸込気流を
副通路より高速でタービン室に流入させ、これによって
タービン車を回転させ、回転ブラシを回転駆動してじゅ
うたん面などを掃除するとき、電気掃除機内に蓄積した
塵埃量に応じて吸込風量が変化しても、副通路に配設し
た風速調節体が副通路の開口面積を変化させて吸込気流
の流速を設定した数値以下に保ち、タービン車の超高速
回転を防止して騒音の低減と軸受部の耐久性の劣化防止
を行なうものである。Effect: With this configuration, the main passage is blocked by the shielding plate, and the suction airflow is allowed to flow into the turbine chamber at a higher speed than the secondary passage, thereby rotating the turbine wheel and rotating the rotating brush to clean carpet surfaces, etc. Even if the suction air volume changes depending on the amount of dust accumulated inside the vacuum cleaner, the wind speed regulator installed in the sub passage changes the opening area of the sub passage to maintain the flow velocity of the suction air below the set value. This prevents the turbine wheel from rotating at extremely high speeds, thereby reducing noise and preventing deterioration of the durability of the bearing.

In Figures 1 to 4, 1 is a turbine nozzle connected to a vacuum cleaner via a hose/extension pipe, with a rotating brush chamber 3 containing a built-in rotating brush 2 at the front and a turbine wheel 4 at the rear.
The turbine chamber 8 includes an upper body 5, a lower body 6, and a connecting pipe 7. The connecting tube 7 is held between the upper body 5 and the lower body 6 so as to be rotatable within a certain range. A connecting pipe 9 is rotatably connected to the connecting pipe 7 via a connecting ring 10, and is connected to the hose or extension pipe. A front body 11 is removably connected to the upper body 5 and the lower body 6 by means of a pair of buckles 12, and covers the rotating brush chamber 3 from above. Brush bristles 13 are provided on the outer periphery of the rotating brush 2.
are arranged in a spiral pattern. 14 is a bearing vibe that rotatably holds the turbine shaft 15 holding the turbine wheel 4;
A belt 16 is stretched between the end of the turbine shaft 15 opposite to the turbine wheel 4 and a pulley 17 provided at the end of the rotating brush 2.

２２より形成されている。Reference numeral 17 includes an operating knob 18 that protrudes upward from the upper body 5, and a main passage 19 that communicates between the turbine chamber 8 and the rotating brush chamber 3.
With a switching lever that integrally has a shielding plate 20 for opening and closing, when the knob 18 is positioned in the eight turbine chambers as shown in FIG.
8 is located at the end of the turbine nozzle l, as the switching lever 17 slides, the shielding plate 20 slides toward the end to open the main passage 19 (21 is located in front of the turbine wheel 4). The formed auxiliary passage constantly communicates the turbine chamber 8 and the rotating brush chamber 3, and is formed by an upper body 5, a lower body 6, and a closing plate 22.

The closing plate 22 constitutes an air volume regulator that changes the opening area of the sub passage 21 in accordance with the suction flow rate airflow passing through the sub passage 21.
次に上記構成に於ける作用について説明する。Next, the operation of the above configuration will be explained.

た空気流はタービン車４に衝突してこれを回転させる。When cleaning the carpet, the knob 18 is positioned on the turbine chamber S side, the main passage 19 is closed by the shielding plate 20, and the suction air flow is allowed to flow into the turbine chamber 8 through the sub passage 21. The incoming airflow collides with the turbine wheel 4 and causes it to rotate.

２１を高さ方向で広げる。This rotation is then transmitted by the belt 16 to the rotating brush 2.
The machine rotates and scrapes up the dust from the base of the carpet fibers, making it easy to clean the carpet. By the way, when this turbine nozzle 1 is connected to a vacuum cleaner with good suction performance and starts to be used, the dust passes through the auxiliary passage 21 and enters the turbine chamber S because no dust has accumulated inside the vacuum cleaner body.
The suction air flow that flows into the turbine wheel 4 and rotates the turbine wheel 4 attempts to flow in at high speed and collides with the blocking plate 22 . As a result, a moment is generated that rotates the lower end side toward the turbine wheel 4 using the closing plate shaft 23 as a rotation axis, and the closing plate 22 is rotated until it is balanced with the spring biasing force of the coil spring 24. Expand in the height direction.

を発生することな（使用できるものである。As shown in FIG. 4, the passage height of the sub passage 21 at this time is b
becomes. On the other hand, when the flow velocity of the suction airflow is below a certain value, that is, when the suction air volume is below the set suction air volume, the closing plate 22 becomes vertical due to the spring biasing force of the coil spring 24, and at this time, the passage of the sub passage 21 The height will be a. As is clear from FIG. 4, since a<b, the opening area of the auxiliary passage 21 increases by an amount corresponding to the height difference, and the flow velocity of the suction airflow decreases, causing the turbine wheel 4
This will prevent the turbine wheel 4 from rotating at an extremely high speed. As mentioned above, the rotation of the blocking plate 22 occurs when the air volume exceeds the set air volume, and as the air volume increases, the rotation angle increases and the passage height of the sub passage 21 becomes thicker. The flow velocity of the suction airflow that impinges on the turbine wheel 4 is kept almost constant.As a result, the turbine wheel 4 can be prevented from rotating at an extremely high speed, and the high-frequency waves generated when the blades of the turbine wheel 4 cut the suction airflow intermittently at high speeds can be prevented. It can reduce noise by reducing sound. Also, it can reduce noise by reducing noise.
Since ultra-high speed rotation conditions do not occur, there is no deterioration in the durability of these bearings. Furthermore, even when connected to a vacuum cleaner body with higher suction performance, the rotation angle of the closing plate 22 becomes wider (becomes) and the flow rate of the suction airflow is automatically kept constant, resulting in an increase in noise. It can be used without causing any damage or deterioration of the durability of the bearing part.

、じゅうたんの種類を選ばない効果もある。By the way, this effect is the same not only when the turbine nozzle 1 is floating in the air, but also when it is actually used when it is grounded on a carpet. However, unlike the conventional method, the rotational speed of the turbine wheel 4 and rotating brushes is kept constant, and the above-mentioned increase in noise and decrease in durability can be prevented, and there is also the effect that it can be used regardless of the type of carpet.
次に第２の実施例について第５図に基づいて説明する。Next, a second embodiment will be described based on FIG. 5.

is a closure valve made of an elastic soft material such as vinyl chloride, which forms a sub passage 21 between the upper body 5 and the lower body 6, and is attached to the upper body 5 with the upper part fixed and the lower part as a free end. There is.

受部の耐久性の劣化が防止できるものである。In the above configuration, when the main passage 19 is closed with the shielding plate 20 and used for cleaning the carpet surface, when suction @ fleas exceeding the set air volume flows into the turbine chamber 8, as in the case of the first embodiment, The upper part of the blockage valve 31 fixed to the upper body 5 serves as a fixed end, and the valve element rotates with its lower end serving as a free end. As shown in FIG. 5, when the blockage valve 1 is rotating, the passage height of the auxiliary passage 21 is b, and when the suction air volume that is less than the set air volume flows into the turbine chamber 8, the blockage valve 31 rotates. If the passage height when not moving is a, then a<b, and the passage surface roughness increases by an amount corresponding to the difference in passage height, preventing an increase in the incoming air flow velocity, resulting in an increase in noise and damage to the bearing section. Deterioration of durability can be prevented.
