本発明は電気掃除機の吸込口に係り、特に回転ブラシ、
これを回転駆動する電動機等を内蔵する吸込口に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a suction port of a vacuum cleaner, and particularly to a rotating brush,
This relates to a suction port that has a built-in electric motor or the like that rotates the suction port.
（従来の技術）
この種の吸込口は電動機により回転ブラシを回転させ、
この回転ブラシの回転によりじゅうたんからごみを効果
的にかき出すことにより、じゅうたん掃除を効果的に行
なえるようになっている。(Prior art) This type of suction port rotates a rotating brush using an electric motor.
The rotation of this rotating brush effectively scrapes out dirt from the carpet, making it possible to effectively clean the carpet.
ところで、回転ブラシは毛足の長いじゅうたんを掃除す
る時やじゅうたんに強く押し付けられた時に非常に大き
な抵抗を受け、電動機に流れる負荷電流も大きくなる為
、従来では専ら、大きな負荷電流が流れてもさほど問題
とならない単相交流整流子電動機を用いて、回転ブラシ
を回転駆動するように構成しているものであった。By the way, when a rotating brush is used to clean a carpet with long piles or when it is pressed strongly against the carpet, it encounters a very large amount of resistance, and the load current that flows to the motor also becomes large. The rotary brush was configured to rotate using a single-phase AC commutator motor, which did not pose much of a problem.
（発明が解決しようとする問題点）
ところが、単相交流整流子電動機は比較的大型で重量的
にも重い為、このような電動機を内蔵する吸込口自体も
大型化し、重量が増加することになり、その取扱性や操
作性を悪くすることになっていた。(Problem to be solved by the invention) However, since a single-phase AC commutator motor is relatively large and heavy, the suction port itself that houses such a motor becomes larger and heavier. This resulted in poor handling and operability.
又、単相交流整流子電動機に比較して小型で軽量の交流
マグネット電動機を使用して、吸込口の小型化、軽量化
を計り、取扱性や操作性を高めることが考えられるが、
単に交流マグネット電動機を用いた場合には大きな負荷
電流が流れた際の発熱が問題となり、そのままでは実用
化できず、そして電動機の発熱を抑えるために冷却ファ
ンを設けた場合には吸込口の小型化、軽量化に対し太き
な障害となるものである。It is also possible to use an AC magnet motor, which is smaller and lighter than a single-phase AC commutator motor, to make the suction port smaller and lighter, and to improve handling and operability.
If an AC magnet motor is simply used, heat generation will be a problem when a large load current flows, and it cannot be put to practical use as it is, and if a cooling fan is installed to suppress the heat generation of the motor, the suction port will have to be small. This is a major obstacle to reducing the size and weight of the product.

ト電動機を用いても実用上問題を生じることがない。(Function) When the rotating brush 2 is strongly pressed against the carpet surface or receives a large force from the long bristles of the carpet, it moves upward and retreats from the carpet surface, thereby reducing the load applied to the electric motor 3. Reduce. Therefore, the current flowing through the electric motor 3 is also suppressed to a small level, and there is no problem in practical use even if a magnet electric motor is used.

くことがない。In Figure 1, the arrows indicate the flow of cooling air.
This flow will be explained. This flow of cooling air is generated by the operation of an electric blower inside the vacuum cleaner body, which will be described later, and outside air enters the electric motor chamber 18 through an air hole (not shown) provided in the upper case 5 near the electric motor 3. , flows through the inside of the motor 3 and around the resistor 40 through a through hole (not shown) in the wall of the communication path 15 to the dust suction passage, thereby cooling the motor 3 and the resistor 40. Therefore, an inexpensive cement resistor or the like can be used as the resistor 40, and of course there is no problem caused by heat generation.

できる。Carpet cleaning is performed while moving the suction port main body l over the carpet, and at this time, the rotating brush 2 automatically adjusts the resistance received by vertical movement, thereby keeping the load applied to the electric motor 3 small. In other words, if the carpet has long piles or if it is pressed strongly against the carpet surface, the rotating brush 2 will be subjected to extremely large resistance, but in this case, the bearing assembly 25 that supports the rotating brush 2 will be pushed inside the groove 30. Since the rotary brush 2 can be moved up and down, the rotating brush 2 moves upward (in this embodiment, moves diagonally upward) to retreat from the carpet surface and automatically adjusts to reduce the resistance it receives. Thereby, the load applied to the electric motor 3 is suppressed to a small level, and an increase in load current is also suppressed. Therefore, even if an AC magnet motor is used as the motor 3, carpet cleaning can be performed without causing any practical problems.
尚、回転ブラシ２に上動により吸収できない大きな負荷

に一定の荷重を加えるようにすることが望ましい。In the above embodiment, the bearing assembly 25 is urged downward by the spring 31, but the spring 31 may be omitted. However, if the rotating brush 2 is positioned at the lowest position only by its own weight, it is likely to become unbalanced during rotation, which will result in noise and vibration. It is desirable to always apply a constant load.

A large load is not applied to the electric motor even when it is pressed strongly against the carpet surface or the carpet has long piles, and a small and lightweight magnet electric motor can be used for practical use. It can be made smaller and lighter, and its handling and operability can be significantly improved.
