As described in 61-7806 and JP 61-7807 and JP-effectively dust Ai adhering to carpet as a suction port body to effectively clean both the hard floor and carpet In order to absorb dust, there is one provided with a rotating brush and a turbine for driving the rotating brush. The suction opening body has a suction passage connected to a dust collector of a vacuum cleaner and a brush chamber opening toward the floor formed by a partition wall on a main body traveling on the floor, and a turbine formed in the suction passage. And a rotating brush driven by a turbine via a driving member in the brush chamber.

が邪魔になるなど取扱いが困難であった。In the above prior art, a horizontally long brush chamber opening toward the floor and a turbine chamber having a turbine at the rear are provided, and a suction air passage and a transmission chamber communicating with an extension pipe are provided. The rotating brushes are supported by bearings and housed rotatably, and the rotating brushes and the turbine are connected by a belt in a transmission chamber. For this reason, the suction port itself becomes large, and operability or handling is inconvenient. In addition, when performing maintenance such as removing dust, lint, and hair wrapped around the rotating brush, handling was difficult because the belt hindered removal of the rotating brush.

I was letting it.

いた。On the other hand, the rotation of the turbine is reduced and transmitted by a power transmission belt stretched between a small pulley provided on the shaft end of the turbine and a large pulley provided on the rotary brush. I have. Therefore, since the turbine rotates at several times the rotation speed of the rotating brush, a speed fluctuation occurs in the flow flowing into the turbine and interferes with the turbine. Is more likely to occur. In particular, when the suction opening is separated from the cleaning surface, the rotating brush is in a no-load state, and the amount of air suction increases, so that the number of rotations of the turbine and the rotating brush increases. There was a problem of giving pleasure. In addition, when cleaning a carpet with long bristle feet, only the turbine is rotating if the rotating brush reduces resistance due to the resistance of the rotating brush, or if it becomes unable to rotate due to suction of large dust. In addition, the pulley and belt jumped, causing noise.

FIG. 1 is a front view of the mouthpiece main body 1, showing a state in which an upper case is partially removed. Here, the lower case 2 has a bumper 3 for shock absorption in front and side, and a wheel 5 for movement. A bent joint 4 for putting dust from the suction port 6 on the suction airflow and sending the dust to a cleaner body (not shown) is located at the rear. A rotary brush 7 is arranged in the suction port 6, and both ends are rotatably supported by bearings 9. A turbine 10 is provided inside the bearing 9 and is connected to the rotary brush 7. On the outer periphery of the rotating brush 7, there are a base 16 having a fitting groove which is continuous in a longitudinal direction on a spiral line, and a blade 23 having a soft pliability which fits into the fitting groove. The rotating brush 7
A partition 11 is provided between the turbine 10 and the turbine 10, and a turbine chamber 12 is formed. The lower case 2 has a guide flow path 1 for guiding the air passing through the turbine 10 to the bent joint 4.
4 are arranged. A removable brush cover 15 that covers the rotary brush 7 and the turbine 10 has an intake port 13 opened facing the turbine 10, and includes a switching lever 8 for detachably attaching to the suction main body 1. Although the intake port 13 is not shown, the same effect can be obtained even if it is located on the front surface of the lower case 2.

The rotating brush 7 rotates in synchronization with the rotating force, and the surface to be cleaned is scraped up by the blades 23 of the rotating brush 7, and smoothly bends along the suction airflow from the suction port behind the rotating brush 7. 4 and is sucked into the cleaner body.

がないので吸込性能が維持できる。Here, if the suction main body 1 is in close contact with a carpet with long hairs, the gap with the floor surface is lost and the suction airflow tends to be insufficient. However, the suction airflow can be supplemented from the suction port 13 of the turbine 10. In addition, the rotation force of the turbine 10 can be prevented from being reduced, and the rotation of the rotating brush 7 can be continued to effectively absorb dust and lint adhering to the carpet. In addition, turbine 1
Since the zero intake port 13 is not in contact with the floor surface, it is possible to prevent rotation failure due to dust and lint adhering to the bearing 9 and the like of the rotating brush 7. Moreover, the turbine chamber 1
2 can reduce the gap with the outer periphery of the turbine 10, so that the efficiency of the turbine 10 is improved. Furthermore, turbine 1
Since there is no entry of hair or cotton dust, which is a factor that hinders the zero rotational force, suction performance can be maintained.

なり、掃除中の不便さが解消される。On the other hand, in the case of cleaning the floor surface, the rotation of the rotating brush 7 is unnecessary. Even if the suction port main body 1 is in close contact with the floor surface, a gap through which air flows in is secured, and thus the suction port 6 is provided with a sufficient suction airflow. Therefore, the intake airflow from the intake port 13 of the turbine 10 does not rotate the turbine 7 due to its low speed. Therefore, there is no need to switch the presence or absence of rotation of the turbine 7 according to the cleaning surface, and the inconvenience during cleaning is eliminated.

室２０がなくなるので吸口本体の小形化ができる。Next, as shown in FIG. 2, the brush cover 15 is opened by operating the switching lever 8 of the brush cover 15 to remove the hair and lint entangled with the rotating brush 7. The cleaning can be performed by removing the rotating brush 7 and the turbine 10. Thus, as in the conventional mouthpiece shown in FIG.
Unlike the case in which the rotary brush 18 is connected to the turbine 19 by the belt 22, no trouble is required to remove the rotating brush 18. Further, since the turbine chamber 20 located behind the rotary brush chamber is eliminated, the size of the suction main body can be reduced.

本体の低騒音化が図られる。The turbine 10 integrated with the rotary brush 7 rotates at a speed of about 3,000 rpm to about 5,000 rpm, and the torque of the turbine is reduced by a belt and transmitted to the rotary brush. Compared to the case where the rotation speed of the turbine is greatly reduced, the speed fluctuation of the flow flowing into the turbine is less likely to occur, and the number of turbine blades *
It is possible to reduce the blade rotation noise based on the rotation speed. Even if a blade rotation sound is generated, the frequency is in a low frequency band in frequency, so that it is hard to be heard by human hearing and is solved from discomfort during cleaning. Furthermore, a belt 22 for power transmission
Since the pulley 21 and the pulley 21 are not required, tooth skipping and belt banging noise caused by a timing deviation are eliminated, so that the noise of the suction main body can be reduced.

Since the airflow flowing from the intake port 13 of the turbine 10 and the blade rotation sound and the vortex sound generated by the turbine are absorbed by the sound absorbing material 17, noise can be reduced.
