A space is maintained between them, and the lead wire can freely move in accordance with the movement of the bending joint 6.

The lead wire 48 is supplied to the motor 2 by the wiring shown in the circuit diagram of FIG.

Here, the LED lamps 56, 57, 58 on the substrate 55 arranged in the wiring are turned off when the rotary brush 3 stops, and are sequentially turned on by the switch 59 (see FIG. 5) at the end of the hose 45. The light is turned on in accordance with the rotation state, and is provided so as to be confirmed from the display unit 60 of the upper case 13 as shown in FIG.

Since the electric vacuum cleaner of the present embodiment is configured as described above, first, the following operations and effects are exhibited.

(A) When connecting the bent joint 6 to the extension pipe 46, the inner periphery of one end of the extension pipe 46 is inserted into the outer periphery of one end of the bent joint 6, but the connection is simultaneously made on the bent joint 6. The connecting pin 47 of the connector element thus inserted is inserted into the connector element 46 'on the extension pipe 46 side, so that the feeder lines are connected together with the connection of the bent joint 6 and the extension pipe 46. Therefore, the connection operation can be simplified.

(B) In addition to the motor power supply line being provided inside the extension pipe 46, the power supply wiring (lead wire) 48 on the casing 18 side of the bent joint 6 and the suction body 1 is also protected by the protective covers 49 and 18 '. Even if these covers 49 and 18 'are not exposed to the outside, and even if these covers 49 and 18' are provided, the cover 1 on the casing 18 side so that the protective cover 49 can rotate together with the bent joint 6 in the circumferential direction of the casing projection 18A.
8 ', the joint 49 is guaranteed to rotate,
Further, the lead wire 48 covered by the covers 49 and 18 '
Is guided toward the suction body 1 with a slack that allows the bending joint 6 to rotate in the circumferential direction due to the covered space, so that the rotation in the two different directions is not suppressed by the lead wire 48, and the lead wire 48. Also, no excessive force is applied, and the wiring 18 is not cut or twisted.

Then, the lead wire protection covers 49, 18 '
When the suction main body 1 is put under furniture or a desk during cleaning due to the presence of the cable, the wiring (lead wire) 48 of the joint portion is caught to prevent the cleaning operation, or the connection is strongly caught and the wiring is disconnected. And no trouble such as shortening the wiring life due to tension is caused.

(C) As described above, the bent joint 6
And the extension pipe 46 bend the inner circumference of one end of the extension pipe 46 and
Since the connection method is detachably inserted into the outer circumference of the vacuum cleaner, the inner circumference of one end of the extension pipe 46 (on the side where the bending joint 6 is fitted) is not exposed to the suction air path of the vacuum cleaner at the time of connection. Dust and the like do not adhere to the inner peripheral wall at one end of the extension pipe 46. Therefore, when the operation of the vacuum cleaner is stopped, the extension pipe 46 is slid along the fitting surface 6A of the joint 6 and pulled out. Since the inner circumference of one end of the extension tube 46 to which dust and the like are unlikely to adhere to the 6A is always involved, it is possible to prevent dust from spilling from the extension tube 46 side to the connector element (the connection pin 47 and the supporting portion 47 'thereof) on the joint 6. Thus, dust accumulation on the connector element can be prevented.

(D) Even if dust or moisture is applied to the connection pins 47, they are exposed on the fitting surface 6A when the extension tube 46 is pulled out.
Can be easily wiped away. Therefore, the reliability of the electrical connection of the connector element is improved.

(E) By removing the protective cover 49, maintenance of the connector elements 47 and 47 'and the lead wire 48 can be easily performed, and assembly of these parts can be easily performed. (F) Further, according to the present embodiment, the lead wire 48 is

Furthermore, the described other operation of the present embodiment, after the case of operation of connecting the respective components as shown in FIG. 5, when turning on the switch 59 in the hose 45 distal to the terminal C ₂ side, The electric blower on the vacuum cleaner main body 44 side and the motor 2 on the suction main body 1 side start operation, and one LED lamp 56 (green) on the display unit 60 is turned on. In this state, since the rotating brush 3 rotates at a low speed, it is suitable for cleaning thin carpets and tatami mats.

[0038] Then the switch 59 the motor 2 of the suction port body 1 is turned on to the terminal C ₁ side is similarly high speed even rotary brush 3 for a high-speed operation. At this time, the LED lamp 56
(Green) and 57 (green) are lit. In this state, it is suitable for thick carpet cleaning.

As shown in FIG. 7, the suction body 1 of this embodiment is provided with electrical components such as a positive temperature coefficient thermistor 61 and a fuse 62, and is electrically connected to the motor 2. When the rotating brush 3 is caught by a foreign substance or the like and the rotation is locked, the positive temperature coefficient thermistor 61 generates heat to increase the resistance, and the direction of the flowing current changes to the side (a).
The LED lamp 58 (red) is turned on to notify the user of the abnormality. This LED lamp 58
When (red) is turned on, the green LED lamps 56 and 57 are turned off.

According to this embodiment, the following effects can be obtained in addition to the operations and effects described in the above (a) to ( f ).

Since the rotating speed of the rotating brush 3 can be selectively used between high and low, cleaning can be performed while rotating at a low speed even on a tatami mat, and cleaning can be performed on the tatami mat without damaging the tatami while having a sweeping effect. it can. In addition, since the state of rotation is displayed on the upper surface of the mouthpiece, it is possible to immediately recognize that the floor has been damaged by cleaning the floor while rotating the rotating brush, or that the rotation has been locked by entangled with foreign objects in the rotating brush, The rotating brush can be used at normal rotation.

Since the rotating brush bearing can be held with a pressing force set in a fixed direction by a spring, even if an unbalance amount occurs in the rotating brush, it is possible to suppress the vibration noise of the rotating brush caused by the unbalance. it can.

Since the flange of the rotary brush pulley is provided on the inner side, even if the rotary brush is removed from the suction body for maintenance, the belt can be smoothly removed without being caught by the flange.

The protective cover 4 attached to the bending joint 6
Since the casing 9 has a cylindrical spigot fitting on the casing 18 side and a protection cover 49 on the bending joint 6 side, the fitting section is opened even if a large external force is applied to the joint section. Does not shift.
