体に接続されている。Structure of a conventional example and its problems FIG. 1 shows a suction tool with a built-in rotating brush in a conventional vacuum cleaner of this type.In other words, in front of a main body 1 of the suction tool, there is a rotating brush chamber 3 having a rotating brush 2. However, a turbine chamber 5 having an air turbine 4 is provided at the rear. A brush body 6 is installed on the outer periphery of the rotating brush 2, and its tip is a suction port 7 provided below the rotating brush chamber 3.
It is made to protrude from the top. 8 is a belt stretched between the air turbine 4 and the rotating brush 2;
The driving force of the air turbine 4 is transmitted to the rotating brush 2. Further, a partition wall 9 is provided between the rotating brush chamber 3 and the turbine chamber 5, and a vent hole 10 is opened in a part thereof facing the air turbine 4. A pipe 11 is provided at the rear of the turbine chamber 5 and is connected to the cleaner body via an extension pipe (not shown) and a hose (not shown).

ブラシ体６により被掃除面をかき上げて掃除を行
う。 In the above configuration, when the vacuum cleaner is operated to clean, the suction port 7 is connected to the rotary brush chamber 3 and the ventilation port 1.
0, air flows to the air turbine 4 and the pipe 11, causing the air turbine 4 to rotate. This rotational force is transmitted to the rotating brush 2 via the belt 8, and the brush body 6 scrapes up the surface to be cleaned to perform cleaning.
ところで、砂つぶなどの重量物を吸込もうとし

空気が回転ブラシ２の上方を通つて流れ、吸込口
７から通気口１０への流れが分散される。したが
つて、重量物を通気口１０へ吸込むだけの気流が
なく、重量物吸込が悪いという欠点があつた。 By the way, when trying to suck in a heavy object such as sand particles, the rotating brush chamber 3 is larger than the conventional suction device that does not have a built-in rotating brush, so the suction air flows above the rotating brush 2 and the suction The flow from the port 7 to the vent 10 is distributed. Therefore, there was a drawback that there was not enough airflow to suck the heavy objects into the vent 10, and the suction of the heavy objects was poor.
この欠点を解消するため、第２図に示すよう

ブラシ室３よりは低い上壁１２を有する吸込通路
１３を設け、一担分散された気流をこの吸込通路

えられている。 In order to eliminate this drawback, as shown in Fig. 2, a suction passage 13 having an upper wall 12 lower than that of the rotating brush chamber 3 is provided between the rotating brush chamber 3 and the turbine chamber 5, so that the suction passage 13 has a lower upper wall than the rotating brush chamber 3. It has also been considered to create a strong flow by concentrating the airflow in the suction passage 13 to improve the suction performance of heavy objects such as sand pellets.

までも掃除ができないという欠点があつた。 However, in the case of the above configuration, since lint, cotton dust, etc. are light, they are drawn upwards into the rotating brush chamber 3 by the rotational force of the rotating brush 2 and are drawn into the rotating flow of the rotating brush 2, and from there, the lint, cotton dust, etc. It has the disadvantage that it continues to rotate around inside the chamber 3 along with the rotating brush 2, and is not easily sucked into the suction passage 13, making it impossible to clean forever.

A rib is provided that protrudes from the rotary brush chamber and divides the rotating brush chamber into upper and lower parts over its entire width, and the rib is cut out at the vent portion to form a passage from above the rib to the cutout portion. Therefore, light dust such as lint flowing upward in the rotating brush chamber reaches the cutout through the passage above the rib and is guided to the vent.

４あるいは４５へ吸込まれる。 Next, when light objects such as lint and cotton waste are scraped up from the surface to be cleaned by the rotating brush 32, some of them are sucked into the suction passage 29 in the same way as heavy objects, while other light objects are rotated vigorously. The brush chamber 26 is scraped upward. At the upper rear part of the rotating brush chamber upper part 26, a partition wall 31 is provided with a rib 28.
A passage 55 is formed because the tip is offset backward from the tip. Therefore, light dirt moves from above the rotating brush chamber 26 to the passage 55 and is pulled into the central vent 44 in the same way as heavy objects.
In this case, the airflow is weaker than that of the suction passage 29, but because it is light dust, it moves sufficiently toward the center. The central part thereof merges with the suction passage 29 through a notch 54, and is connected to the heavy object through the ventilation hole 4.
