(Installation)
As shown in FIG. 7, the rotating brush 6 is inserted and attached from the side direction with respect to the traveling direction S of the floor suction tool 100. As shown in FIG. 8, an opening 29 for attaching the rotating brush 6 is open on one side surface of the main body case 3, and one side opposite to the surface (lower side) facing the surface to be cleaned G (lower side). The opening low part 30 lower than the side surface of the main body case 3 is provided in the part, and the convex shape 31 is provided in the opening low part 30.

A dust removing tool 11 for removing dust entangled with the rotating brush 6 is provided at the back of the opening 29. The dust removing tool 11 has a hollow tube shape and a hollow inner diameter as shown in FIG. A claw portion 33 is provided so as to protrude toward the portion 34 and further extend inside the main body case 3. Further, the inner diameter of the dust removing tool 11 is smaller than the outer shape of the bristle brush 27 provided on the rotating brush 6 and is close to the hairline so as to scrape the bristle brush 27.

In the dust removing tool 11, the entire circumferential groove portion 35 and the entire circumferential convex portion 36 are sandwiched between the lower case 2 and the lower cover R9 as described above, and are fixed by screws 37a as shown in FIG. The dust removing tool 11 removes dust from the rotating brush 6 when it is removed, and functions as a supporting member for the rotating brush in the attached state. The dust removal will be described in detail in the description of the removal at a later stage.

When the rotary brush 6 is to be inserted from the opening 29 as shown in FIG. 7, the rotary brush 6 passes through the hollow portion 34 of the dust removing tool 11 and is provided on the cylindrical member 24 of the rotary brush 6 as shown in FIG. The wider groove 25b and the claw portion 33 of the dust removing tool 11 are fitted together, and the claw portion 33 is fitted until it is almost in contact with the deepest portion of the groove 25b. The bristle brush 27 is configured to pass while the claw portion 33 is provided.

When the rotating brush 6 is further pushed in as shown in FIG. 11, the rotating brush 6 is moved to the bearing convex portion 10a of the bearing portion 10 sandwiched between the lower case 2 and the lower cover L8 and fixed with the screw 37b as described above. The guide part opening 26 a provided in the guide part 26 is fitted and supported, and both ends of the rotating brush 6 are supported by the dust removing tool 11 and the bearing part 10.

The bearing projection 10a has a cross shape as shown in FIG. 11 (a), and the guide opening 26a is also a cross-shaped opening as shown in FIG. 9 (b). The driving force of the motor 16 transmitted to the bearing unit 10 is reliably transmitted to the rotating brush 6 without rotating and rotates.

  In order to complete the insertion of the rotating brush 6 into the main body case 3, as shown in FIG. 15A, the guide concave portions 38a and 38b provided in the main body case 3 and the locking convex pieces provided in the gripping portion 7 are used. When inserted in accordance with the position 28, the lever 7a comes to the pre-attachment position as shown in FIG.

  However, in this state, the rotating brush 6 is only in the mounting position and is not yet fixed, and the gripping portion 7 protrudes from the side surface of the main body case 3 as shown in FIGS. 13 (a) and 13 (b). Yes. As shown in FIG. 16A, the gripping portion 7 of the rotating brush 6 is directed outward from the main body case 3 by the biasing means 39 made of, for example, a spring-spring-shaped elastic body with respect to the cylindrical member 24. Since it is biased, the protruding portion makes it easier for the gripping portion 7 to grip. In addition, the protrusion allows the user to visually understand that the installation is not completed.

  In order to fix the rotating brush 6, the gripping portion 7 is further pushed against the biasing force of the biasing means 39 to a position where the lever 7a contacts the opening lower portion 30, and the lever 7a as shown in FIG. Is moved to the mounting position.

Then, as shown in FIG. 15B, the locking convex piece 28 of the gripping portion 7 is fitted into the groove-shaped locking portion 32 shown in FIG. 8, and the rotary brush 6 is fixed and fixed from that position. It will be in a state that can not be taken out. And from this fitting position, the holding part 7 becomes substantially flush with the side surface of the main body case 3 and can be stored in a position that does not get in the way during cleaning.

Furthermore, the convex shape 31 provided in the opening low part 30 is located between the attachment position where the lever 7a moves and the pre-attachment position. As shown in FIG. In the state of moving (turning) to the attachment position side, the lever 7a protrudes from the position closest to the opening lower part 30 of the main body case 3, so that the lever 7a contacts the convex shape 31 and rides on with resistance. Then, it moves to the mounting position so as to get over it.

Therefore, the convex shape 31 provides resistance when the lever 7a moves to the removal position, so that the convex shape 31 prevents the lever 7a from moving to an unintended removal position and is difficult to come off. This completes the installation.

(Removal)
As shown in FIG. 12A, the lever 7a is moved to the removal position while resisting the resistance of the convex shape 31 as opposed to the attachment. When the lever 7a comes to the removal position, the latching state of the latching portion 32 of the main body case 3 and the latching convex piece 28 of the gripping portion 7 is released as shown in FIG. 15A, and the biasing force of the biasing means 39 is released. 13 (a), (b), and FIG. 16 (a), the grip portion 7 protrudes from the side surface of the main body case 3, so that the grip portion 7 can be easily gripped when the rotary brush 6 is taken out. Good workability.

When the rotary brush 6 is pulled out of the main body case 3 with the gripping part 7, the groove 25b provided in the cylindrical member 24 of the rotary brush 6 and the nail of the dust removing tool 11 as shown in FIG. Since the portion 33 is fitted to the deepest part of the groove 25b until it comes into contact with the deepest portion of the groove 25b, dust such as lint and hair entangled around the cylindrical member 24 of the rotating brush 6 is collected by the nail portion 33. It is scraped off and removed from the cylindrical member 24 of the rotating brush 6.

As described above, the inner diameter of the dust removing tool 11 is smaller than the outer shape of the bristle brush 27 provided on the rotary brush 6 and close to the hairline, as described above. Then, the dust entangled with the bristle brush 27 is scraped off and removed. In this way, dust entangled with the rotating brush 6 in the process of removal can be removed without touching with hands, so that it is hygienic and easy to maintain.

  As described above, in the first embodiment of the present invention, the grip portion 7 that is gripped to remove the rotating brush 6 is projected from the side surface of the main body case 3 by the biasing force of the biasing means 39. The gripping part 7 can be easily gripped and the rotary brush 6 can be easily taken out, so that the workability can be improved and the maintainability of the rotary brush 6 is improved.

Further, in the process of taking out the rotating brush 6 that is easy to take out, dust such as lint and hair entangled around the cylindrical member 24 of the rotating brush 6 is entangled with the bristle brush 27 by the claw portion 33 of the dust removing tool 11. Since the dust is scraped off and removed by the outer peripheral wall 40 of the dust removing tool 11, the dust can be removed without touching the dust entangled with the rotating brush 6 by hand, and the hygienic and maintainability is improved.

Embodiment 2
The second embodiment of the present invention differs from the first embodiment of the present invention only in the method of fixing the rotating brush to the main body case, and the structure inside the main body case is the same. Therefore, the fixing method will be described with reference to FIGS. Description of other structures is omitted. As for the structure of the rotating brush, the gripping part 7 (including the lever 7a and the locking convex piece 28) of the rotating brush 6 according to the first embodiment and the handle holding part 61 (the handle) of the rotating brush 60 according to the second embodiment. 62, the engaging part 63, and the rotating shaft part 64), and the other parts are the same, and the description thereof is omitted. Furthermore, the configuration of the entire vacuum cleaner is different from the first embodiment of the present invention only in the floor surface suction tool, and the other configurations are the same, so the description thereof is omitted. The same parts as those in Embodiment 1 are denoted by the same reference numerals.

FIG. 17 is an external view of a state in which the rotary brush of the floor suction tool of the electric vacuum cleaner according to Embodiment 2 of the present invention is unlocked to the disengaged position, and FIG. 18 is an electric vacuum cleaner according to Embodiment 2 of the present invention. It is an external view of the state which locked the rotating brush of the floor surface suction tool of the machine in the attachment position.

The main body case 52 of the floor suction tool 400 includes an upper case 50 and a lower case 52, and an opening 70 for attaching the rotating brush 60 and a lower opening portion 71 lower than the side surface of the main body case 52 are provided in part. ing. An upper case locking projection 80 is provided in the vicinity of the lower opening 71 of the upper case 50 so as to engage with an engaging portion 63 provided on a handle 62 described later.

The rotating brush 60 is provided with a handle 62 that is used when being attached to or detached from the main body case 52 and a handle holding portion 61 to which the handle 62 is rotatably attached by a rotating shaft portion 64.

Holding the handle 62, the rotating brush 60 is inserted into the main body case 52 from the opening 70 to the mounting position. At this time, the handle holding portion 61 including the handle 62 protrudes from the side surface of the main body case 52. This is because the handle holding portion 61 of the rotary brush 60 is urged outward from the main body case 52 by urging means (not shown) made of, for example, a spring-spring-shaped elastic body. This makes it easier to grasp the handle 62.

After the insertion position is inserted, the handle holding portion 61 including the handle 62 is further pushed against the biasing force of a biasing means (not shown) to a position where it comes into contact with the lower opening portion 71, and the handle 62 is rotated. 64, and the engaging part 63 of the handle 62 is moved so as to be related to the upper case locking convex part 80.

Since the upper case convex portion 80 protrudes beyond the rotation range of the engaging portion 63 of the handle 62, the engaging portion 63 contacts the upper case locking convex portion 80 and rides on with resistance. Then, it will move to the fixed position so as to get over it.

Therefore, the upper case convex portion 80 becomes a resistance when the engaging portion 63 of the handle 62 moves to the removal position. Therefore, the upper case locking convex portion 80 prevents the handle 62 from being moved to an unintended removal position and comes off. It has become difficult. When the handle 62 comes to the fixed position, it fits into the lower opening 71 as shown in FIG. 18 and is substantially flush with the side surface of the main body case 52 so that it does not get in the way during cleaning. Complete.

When detaching, the handle 62 is moved to the detaching position while resisting the resistance of the upper case locking projection 80 contrary to the fixing. The handle holding part 61 including the handle 62 protrudes from the side surface of the main body case 52 by the urging force of the urging means (not shown), and the handle 62 is rotated by the rotating shaft part 64 and comes out further outside. Therefore, it is easy to carry and work when taking out the rotating brush 60.
