  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 gripping 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, dust on the floor surface is sucked together with air from the suction port 16 of the floor brush 9 by the suction force generated by driving the electric blower 2 in the cleaner body 1.

  In addition, dust in the case of an obstacle such as a wall is sucked from the front hole 23 by bringing the floor brush 9 close to the wall.

  Thereafter, the dust sucked from the floor brush 9 is sucked together with air from the floor brush 9 into the main body suction port 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 and collected by a dust collection pack housed in the machine body 1.

  Here, when the floor brush 9 is used on a floor surface such as a carpet in which the traveling wheels 15a and 15b sink, the bottom surface portion 17 comes into contact with the soiled carpet, and dust adheres to the bottom surface portion 17 and becomes dirty.

  In this case, when the floor brush 9 is turned over with the vacuum cleaner stopped and the pressed portion 94 of the release button 66 is pushed into the case body 11, it is shown in FIGS. 6 (a) and 6 (b). In this manner, the sliding contact surface 96a of the sliding contact portion 96 slides on the inclined surface 87a of the sliding contact portion 87, and the locking body 82 moves so as to be separated from each other left and right.

  When the release button 66 is pushed to a predetermined position, the distance between the notches 87b of the pair of locking bodies 82 becomes larger than the distance between the two engaging claws 58 of the bottom surface portion 17, and the engaging protrusion 54 is engaged. The engagement with the release mechanism 29 is released.

  At the same time, the bottom surface portion 17 is pushed forward by the urging force of the pushing spring 79 of the pushing mechanism 63, and each engaging portion 56 is disengaged forward from each pre-preparation hole 23, and FIG. 7 (a) and FIG. ), The bottom surface portion 17 is shifted forward with respect to the lower case 12, and the front curved portion 52 protrudes forward of the case body 11.

  The operator grasps the protruding front curved portion 52, pulls the bottom surface portion 17 forward of the case body 11, removes the bottom surface portion 17, and cleans the bottom surface portion 17 by washing with water.

  At this time, the locking bodies 82 and 82 move in a direction approaching each other by the urging force of the locking springs 83 and 83, and the release buttons 66 are moved by the inclined surfaces 87a and 87a of the moving locking bodies 82 and 82. Move upward to return to the original state.

  The washed bottom surface portion 17 is sufficiently dried and then attached to the lower case 12 again.

  At this time, the operator inserts the engaging protrusion 54 of the bottom surface portion 17 from the insertion port 73 and resists the urging force of the push spring 79 while the guide contact portion 53 is in contact with the case side guide portion 27. When pushed backward, the inclined surface 58a pushes the locking body 82 left and right while contacting the notch 87b of the locking body 82.

  Then, when the bottom surface portion 17 is pushed rearward until the engagement claw portion 58 of the engagement protrusion 54 is positioned at the rear portion of the notch portion 87b of the locking body 82, each engagement claw portion 58 is moved to the rear portion of the notch portion 87b. The engaging body 82 is elastically restored by the urging force of the engaging spring 83 to clamp the projecting portions 57 of the engaging projecting portion 54 from both sides, and the pushing body 78 is engaged with each engaging claw portion 58. Is pressed against the locking body 82 and clamped.

  At the same time, each engaging portion 56 engages with each front opening 23 from the front, and the bottom surface portion 17 is prevented from being detached from the lower case 12, and when the floor brush 9 is turned over again, the bottom surface 17 is removed from the case body 11. This prevents the part 17 from falling.

  As described above, in the above embodiment, the bottom surface portion 17 provided so as to cover the lower surface of the motor chamber 36 from the suction chamber 35 is configured to be detachable from the case body 11.

  For this reason, for example, when the floor brush 9 is used on the floor surface of a carpet or the like, the traveling wheels 15a and 15b sink into the carpet or the like so that the bottom surface portion 17 comes into contact with the carpet or the like. Even when the portion 17 becomes dirty, the bottom surface portion 17 can be removed from the case body 11 and easily washed.

  In particular, the lower surface on the side of the motor chamber 36 that houses the motor 41 could not be washed in order to prevent moisture from adversely affecting the motor 41, but by configuring the bottom surface portion 17 to be removable, Can be easily washed.

  Then, the washed bottom surface portion 17 can be easily dried by suspending it or the like, and usability can be improved.

  In addition, since the bottom surface portion 17 can be washed to remove dirt, for example, when cleaning a carpet or the like, dust attached to the bottom surface portion 17 can be prevented from being stained and the usability can be further improved.

  Furthermore, the bottom surface portion 17 is moved forward with respect to the case body 11, and the engagement portion 56 that is disengaged from the front hole 23 and the case body 11 are curved so as to cover a part of the front surface. By providing each of the front curved portions 52 on the bottom surface portion 17, it is possible to remove and wash a part of the front side of the floor brush 9 that easily collides with obstacles such as walls during cleaning work and is relatively dirty, Since the front bending portion 52 protrudes to the front side of the case body 11 in a state where the engagement portion 56 is disengaged, the workability of removing the bottom surface portion 17 can be improved.

  When the release button 66 of the engagement / disengagement mechanism 29 is pressed, the push-out mechanism 63 is moved to the bottom surface in conjunction with the disengagement between the engagement protrusion 54 of the bottom surface portion 17 and the locking body 82 of the engagement / disengagement mechanism 29. The portion 17 is pushed forward, and at the same time, the engagement projecting portion 54 is disengaged and the bottom surface portion 17 is pushed forward, and at the same time, the engagement portion 56 is also disengaged from the front hole 23. Removal workability can be further improved.

  Further, the front opening 23 for suction from the front side of the floor brush 9 is also used for engaging the engaging portion 56, so that a structure for securely fixing the bottom surface portion 17 to the case body 11 is provided separately. Since it is not necessary, the structure of the floor brush 9 can be prevented from becoming complicated, and the front and rear sides of the bottom surface portion 17 can be locked to the case body 11 with the engagement / disengagement mechanism 29, and the bottom surface portion 17 is attached to the case body 11. It can be locked more reliably.

  And since the bottom face part 17 can be removed from the case body 11, the optimal cleaning according to the kind of floor surface is attained by preparing the bottom face parts 17 for tatami mats or carpets.

  Further, by positioning the engagement / disengagement mechanism 29 in the vicinity of the rear running wheel 15b slightly lifted with respect to the floor surface, the release button 66 of the engagement / disengagement mechanism 29 comes into contact with the floor surface during cleaning work or the like, and the bottom surface portion 17 Can be prevented from being accidentally detached from the case body 11.

  Furthermore, since the floor brush 9 is almost in contact with the floor surface except for the bottom surface portion 17, the floor brush 9 is always soiled by removing the bottom surface portion 17, which is the entire portion in contact with the floor surface, from the case body 11. It can be maintained in a state that is not.

  In the above embodiment, the suction chamber 35 and the motor chamber 36 do not have to be separated in a completely airtight state.

  The engagement / disengagement mechanism 29 can have various other configurations.

  Further, 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.
