  Here, as shown in FIG. 4, the locking portion 26 is slidably attached to locking fitting portions 31 provided on both side portions of the lid 15 in the left-right direction. Then, as shown by the solid line, these locking portions 26 lock the lid 15 to the upper case 13 by sliding to the center in the left-right direction of the lid 15 and The lid 15 can be removed from the upper case 13 by sliding it in the direction indicated by the arrow on both sides.

  As shown in FIG. 3, the switch 29 includes a switch main body 33 accommodated in the case body 11 and a switch piece 34 that elastically protrudes upward from the switch main body 33. The switch piece 34 faces the insertion hole 25, turns on the switch 29 when pressed downward by the rib 28, and elastically returns upward when the press by the rib 28 is released. Switch 29 is turned off. That is, the switch 29 detects whether or not the lid 15 closes the opening 23.

  Further, as shown in FIG. 1, the switch 29 is electrically connected to a power supply unit 35 and a control circuit 36 as control means, and turns on and off the power supplied from the power supply unit 35 to the control circuit 36. It is.

  One terminal of the power supply unit 35 is electrically connected to the control circuit 36 via the switch 29, and the other terminal is installed on the ground G.

  The control circuit 36 is electrically connected to the motor 19 and the switch 29, respectively. The control circuit 36 has a function of turning on / off the power supplied from the power source unit 35 to the motor 19 and controlling the driving of the motor 19.

  As shown in FIGS. 2 to 5, the traveling wheel 16 is provided so as to be rotatable in the front-rear direction, and allows the floor brush 9 to travel in the front-rear direction on the floor surface.

  The communication pipe 17 is rotatably provided at the rear part of the case body 11.

  The rotating brush 18 is disposed along the left-right direction of the case body 11, and is rotatable in the front-rear direction. The rotating brush 18 includes a substantially cylindrical brush base 41 serving as a shaft body, and a plurality of cleaning members 42 and 43 provided in a spiral manner around the brush base 41. A shaft 44 projects from both ends. A receiving plate 45 is integrally fixed to the shaft 44 as a bearing. The receiving plate 45 is rotatably supported by a bearing recess 46 in the case body 11. The rotating brush 18 is disposed with the lower part facing the suction port 21 and the upper part facing the opening 23, and the distal ends of the cleaning members 42 and 43 slightly protrude from the lower part of the case body 11.

  In the motor 19, an endless belt body 47 is wound around the rotating shaft 19a and one receiving plate 45 of the rotating brush 18.

  Next, the operation of the above embodiment will be described.

  First, when cleaning, the floor brush 9 is connected to the cleaner body 1 through the hose body 4 and the extension pipe 8. Then, the predetermined setting button 6 is operated to drive the electric blower 2 in a predetermined driving state, and the grip portion 7 of the hose body 4 is operated to cause the floor brush 9 to run back and forth on the floor surface.

  At this time, the dust on the floor surface is sucked together with the air from the suction port 21 of the floor brush 9 by the suction force generated by driving the electric blower 2 in the cleaner body 1.

  Further, when cleaning a floor surface such as a carpet, for example, the rotating brush 18 is rotated by the motor 19 so that the cleaning members 42 and 43 scrape dust from the carpet.

  Thereafter, the dust sucked from the floor brush 9 is sucked together with air from the floor brush 9 into the main body inlet 3 of the cleaner body 1 through the extension pipe 8 and the hose body 4 in order, and then cleaned. It is sucked into a dust collection pack housed in the machine body 1 and captured.

  When the rotary brush 18 becomes dirty due to lint or hair getting tangled in the rotary brush 18 or adhering dust, the locking part 26 is moved in the left-right direction, and the lid 15 is opened. And the rotating brush 18 is exposed to the outside of the case body 11.

  At this time, the switch piece 34 of the switch 29 is elastically restored, so that the switch 29 is turned off, the power supplied from the power supply unit 35 to the control circuit 36 is cut off, and the drive of the motor 19 by the control circuit 36 is controlled. Stops, the motor 19 is stopped, and the rotation of the rotary brush 18 stops.

  In this state, the operator cleans the rotary brush 18 and then fits the lid 15 into the opening 23 again.

  Here, when the lid 15 is attached to the opening 23 while fitting the fitting protrusion 27 into the fitting recess 24, the rib 28 is inserted into the insertion hole 25 and presses the switch piece 34 of the switch 29 downward. As a result, the switch 29 is turned on, power is supplied from the power supply unit 35 to the control circuit 36, and the control circuit 36 can be driven.

  The control circuit 36 controls the rotation of the rotary brush 18 by controlling the drive of the motor 19.

  As described above, according to the embodiment, the control circuit 36 stops the rotation drive of the rotary brush 18 by the motor 19 when the lid 15 is not closing the opening 23, whereby the rotary brush It is not exposed to the outside of the case body 11 from the opening 23 in a state in which the 18 is rotated, and safety during work such as cleaning of the rotary brush 18 can be ensured and usability can be improved.

  Further, by attaching the lid 15 to the opening 23 while fitting the fitting protrusion 27 into the fitting recess 24, the lid 15 can be easily positioned.

  Furthermore, since the drive of the motor 19 can be interlocked with the opening / closing of the opening 23 with a relatively simple configuration in which the switch 29 is turned on / off by inserting the rib 28 into the insertion hole 25, for example, by the lid 15 Compared with the case where the sensor which detects opening and closing of the opening part 23 is used, the manufacturability of the floor brush 9 can be improved and the manufacturing cost can be suppressed.

  In the above-described embodiment, a configuration in which the on / off of the switch 29 is interlocked with the operation of the locking portion 26 is also possible. In this case, for example, the rotating brush 18 does not rotate when the lid 15 is lifted from the opening 23, and the rotating brush 18 rotates only when the lid 15 is securely locked to the opening 23. Therefore, usability can be further improved.

  Alternatively, the opening 23 may be provided in the lower case 12 and the lid 15 may be positioned below the floor brush 9. In this case, by disposing the switch 29 toward the lower side of the case body 11, for example, it is possible to prevent an operator from accidentally pressing the switch 29 with the lid 15 opened, thereby further improving usability. it can.

  Further, the opening 23 may be formed larger than the rotating brush 18 so that the rotating brush 18 can be easily cleaned, and the rotating brush 18 may be detachable from the opening 23. In this case, the rotating brush 18 can be easily detached from the opening 23, and the usability is further improved.

  The vacuum cleaner is not limited to the canister type vacuum cleaner, but is an upright type in which the floor brush 9 is directly formed on the lower surface of the vacuum cleaner body 1. In addition, the vacuum cleaner body 1 and the floor brush 9 are integrated. Even a self-propelled electric vacuum cleaner or a handy type can be used correspondingly.
