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、次のような
ものが考えられている。すなわち、じゅうたん掃除の時

般的であった。BACKGROUND ART Conventionally, the following types of turbine nozzles have been considered. In other words, when cleaning a carpet, the bypass ventilation hole is closed with a wind speed adjustment plate, the vacuum cleaner's suction airflow is throttled, the wind speed is increased, and the turbine is driven to rotate, and this rotation is transmitted to the rotating brush, which is then used to rotate. However, when cleaning hard floors or tatami mats, fully open the bypass ventilation holes.
Most of the intake airflow is gently sucked in through the bypass ventilation hole,
It was common to use turbines and rotating brushes without rotating them.
発明が解決しようとする課題
ところが、近年の電気掃除機の吸込性能の向上にともな
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

初期風量に近い数値の吸込風量でタービンノズルを使用
することとなり、硬質床や畳掃除の時においては通風孔
、及びタービン通風孔を通過する吸込気流の風速が増大
し、両道風孔を通過するときに発生する風切音が大きく
なって騒音の要因となっていた。Problems to be Solved by the Invention However, as the suction performance of vacuum cleaners has improved in recent years, the suction air volume when dust is not collected (hereinafter referred to as initial air volume) has increased. As a result, when you first start using the vacuum cleaner, when you use it after throwing away dust, or until a certain amount of dust is inhaled, the turbine nozzle operates at the initial air volume or at a suction air volume close to the initial air volume. When cleaning hard floors or tatami mats, the speed of the suction air passing through the ventilation holes and turbine ventilation holes increases, and the wind noise generated when passing through the two-way ventilation holes increases, causing noise. This was a factor.
これを解消するには、間通風孔の面積を大きくすれば良
いが、例えば迂回通風孔を太き（しようとしてこの通風
孔の高さを高くすると吸込口体全体の高さも大きくなっ

を一体に形成したものでは無理であった。またタービン
通風孔を大きくするとタービンを回転させる吸込気流の
流速が低下し、タービンの回転が低下してしまう。To solve this problem, the area of the interventilation hole can be increased, but for example, if the bypass ventilation hole is made thicker (and the height of this ventilation hole is increased, the height of the entire suction port body will also increase). In addition, if the width is widened, the sliding amount of the wind speed adjustment plate must be increased, but the sliding amount of the knob used to move and operate the wind speed adjustment board from the outside must also be increased.However, the sliding amount of the knob must be increased as well. is limited by the overall width of the suction port body and the width of the turbine chamber, and it was impossible to increase the width without increasing the width of the suction port body with a structure in which the deflection and the wind speed adjustment plate were integrally formed. If the value is increased, the flow velocity of the suction airflow that rotates the turbine decreases, and the rotation of the turbine decreases.

が低減する。At this time, the boss 26, which is slidable within the elongated hole 25, is inserted into the shielding plate 1'.
9 to the belt 15flR, most of the vent 18 is closed, and the turbine vent 27 in front of the turbine wheel 4 is closed.
Open only. Therefore, the suction airflow of the vacuum cleaner passes through the narrowed turbine ventilation port 27 and passes through the turbine wheel 4.
collides with the belt at high speed and rotates it, and this rotation causes belt 1
6, the rotating brush 2 rotates. On the other hand, when cleaning hard floors or tatami mats, the knob 22 is moved to the end of the turbine nozzle 1 as shown in FIG. Pick 21
When moving from the carpet cleaning position to the hard floor/tatami cleaning position, the boss 22 of the switching lever 20 moves to the lever 23.
While sliding the lever 23 in the long hole 27 of the lower body 6
It is rotated using the boss 24 as a fulcrum. As a result, lever 2
While the boss 26 of No. 3 slides within the elongated hole 25 of the shielding plate 19, the shielding plate 19 is slid to the end side of the turbine nozzle 1, and the vent 18 is fully opened. Now, if the amount of sliding of the shielding plate 19 is L, the amount of movement of the knob 21 is l, the distance between the centers of the bosses 24 and 22 is a, and the distance between the centers of the bosses 24 and 26 is A, then A / a. = L/1 holds true, and in the state shown in FIG.
9 will be transmitted. In other words, the amount of movement of the knob 21 is the same as before, and the amount of sliding of the shielding plate 19 is 1.6 times that of the conventional one, which is 1.6 times that of the conventional one.
The vent area will be six times larger. At this time, the suction airflow is slowly drawn in through the fully opened vent 18, so the turbine wheel 4 stops, and at the same time, the wind noise generated when passing through the vent 18 becomes very small, reducing noise. .

The same parts as those in the first embodiment are given the same reference numerals and the explanation thereof will be omitted, and the different enlargement transmission mechanism will be explained. 31 is a connecting gear consisting of a small gear 32 and a large gear 33, and is connected to a boss 3 formed on the lower body 6 below the switching lever 20.
4 is rotatably fixed to the shaft. A first worm 35 is integrally formed on the side wall of the switching lever 20 on the side opposite to the rotating brush chamber 3, and meshes with the small gear 32. Further, a second worm 36 is formed on the connecting gear 31 of the shielding plate 19 and meshes with the large gear 33. Small gear 3
The numbers of teeth of the gear 2 and the large gear 33 are 15 and 25, respectively, and the modules of each tooth profile are formed to be the same.

のである。In the above configuration, when the knob 21 is moved toward the turbine chamber 8, the first worm 35 and the small gear 32 are engaged with each other, so that the connecting gear 31 rotates clockwise in FIG. 6. This rotation is transmitted to the shielding plate 19 by the meshing of the large gear 33 and the second worm 36, causing the shielding plate 19 to slide toward the end of the turbine nozzle 1, and the vent 18 to be fully opened. The amount of movement of the knob 21 at this time is l, and the shielding plate 1
If the slide amount of 9 is L, then L/1=25/15LF1.67, and the amount of movement of the knob 21 is expanded and transmitted to the shielding plate 19. As a result, the amount of knob movement operation is the same as before. This results in a vent area that is 1.67 times larger than the conventional one. Therefore, similarly to the first embodiment, the wind noise when passing through the vent 18 becomes very small, and the noise is reduced.
