ので、床ブラシ１０の重さが重くなって掃除に疲労を与
えることが多い。The floor brush 10 of the conventional electric vacuum cleaner as described above has the advantage of being able to perform thorough cleaning because the rotary brush 16 is rotated by the motor 20 for cleaning. However, a heavy motor 20 including a rotor and a stator and a light printed circuit board 23 on which electronic components are mounted are separately attached to the left and right of the floor brush 10. Therefore, the weight of the floor brush 10 placed on the floor tends to be out of balance on the left and right. If the left and right weights of the floor brush 10 become uneven, not only will the heavy part be extremely worn, a so-called "uneven wear" phenomenon will occur, but the contact pressure with the floor will change and cleaning will be uneven. May be. Further, since the heavy motor 20 is incorporated in the main body 11, the floor brush 10 is often heavier and fatigues the cleaning.

In order to reduce the fatigue of cleaning, an electric floor brush that drives the floor brush 10 with a motor has recently begun to appear on the market. However, there are various problems in practical use due to weight balance, motor overload, and the like, and the current situation is that an electrically driven floor brush that has been satisfied has not yet been realized. The present invention has been made in order to solve the above-mentioned problems of the present situation, and an object of the present invention is to realize a floor brush for an electric vacuum cleaner having various features such as equalizing the left and right weights of the floor brush.

められる。When the cleaning of the board floor is changed to the cleaning of the carpet floor, the hand switch 7 is switched to the carpet cleaning. By switching to cleaning for carpet, the brush motor built into the floor brush is energized and the rotary brush rotates. As the rotary brush rotates, it knocks out the dust that has sunk in the carpet. The knocked out dust is collected in a dust bag set in the vacuum cleaner.

環的に繰り返されて“自動掃除”が行われる。Further, when cleaning a carpet with a particularly long flocked hair or when tired, the hand switch 7 is switched to the "automatic cleaning" operation of the floor brush. When shifting to "automatic cleaning", the wheel motor is energized and the motor shaft starts to rotate in the normal direction. The rotation torque of the motor shaft that traverses the air passage is divided into left and right torque transmission mechanisms of the main body. Then, the left and right wheels rotate via the pulley and the belt. As a result, the floor brush automatically advances and the dust struck by the rotary brush is sucked. When the floor brush advances a certain distance, the rotation of the wheel motor stops, and this time the wheel motor reverses and the floor brush begins to move backward. The retreat time of the floor brush is set smaller than the forward time. When the floor brush moves backward, it moves forward again, and this forward movement and backward movement are cyclically repeated in sequence to perform "automatic cleaning".

However, since the restriction sheath 37 is asymmetric with respect to the O-O plane, the difference in the flow resistance of the air indicated by the arrow a in FIG. become. As a result, the flow direction of the thread waste and the like is restricted and entanglement is prevented. By the way, since the output shaft 33 is close to the suction port 13a even when the thread waste is entangled, the entangled thread waste can be easily removed.

始する。When the floor surface moves from the board floor to the carpet floor, the hand switch 7 is switched to the carpet cleaning. By this switching, the brush motor 20 built in the floor brush 10 is energized,
The rotary brush 16 rotates. The rotary brush 16 rotates to knock out dust that has sunk at the root of the tuft of the carpet, and collects it in the dust bag in the same manner as described above. Further, when cleaning a carpet with a particularly long flocked hair or when tired, the hand switch 7 is further switched to the "automatic cleaning" operation of the floor brush 10. When the "automatic cleaning" is started, the wheel motor 30 is energized, and the output shaft 33 first starts to rotate forward for a fixed time Tf.

The rotation of 0 stops, and the motor 30 for the wheel rotates in the reverse direction this time, and the floor brush 10 starts to retract. The retreat time Tb of the floor brush 10 is selected so that Tb <Tf with respect to the advancing time Tf. When the floor brush 10 moves backward for Tb time, it moves forward for Tf time again, and the forward and backward movements are cyclically repeated.

になっている。The cleaning of the "automatic cleaning" operation is started from one corner of the room, and the cleaning of the room approaches the end to become the cleaning of the opposite corner. Therefore, during the forward movement time Tf of the floor brush 10, the contactor 44 of the wall sensor 47 comes into contact with the wall and the automatic forward movement of the main body 11 is forcibly stopped. At this time, the belts v1 and v2 slip on the pulleys p1 to p4, and a reverse load applied to the rotating wheel motor 30 is prevented. At the same time, the contact 44 is pushed and the contact 46 is closed. The wall surface is sensed by the contact signal of the contact 46, the forward movement is canceled, and the floor brush 10 retracts after a certain time. In this way, the floor brush 10 can be appropriately adapted to the floor surface or can be switched to "automatic cleaning" to perform semi-automatic cleaning using an electric vacuum cleaner.
