The fixed brush 39 is a non-movable cleaning member whose tip side is in sliding contact with the floor surface to wipe off dust by moving the floor brush 23 back and forth. Like the bristle brush 52, the fixed brush 39 is formed by bundling bristles formed in a thin linear shape with a synthetic resin (for example, nylon) and arranging them in a longitudinal shape (strip shape). The fixed brush 39 is arranged at the bottom of the case body 31. In the present embodiment, the fixed brush 39 is arranged at a plurality of places in the lower part of the case body 31. Specifically, the fixed brush 39 is arranged at positions on both the left and right sides behind the suction port 42 and at a substantially central position in the left-right direction behind them, and is positioned longitudinally along the left-right direction. ing. The tip end side of the fixing brush 39 projects downward from the lower part of the case body 31. In the present embodiment, the tip end side of the fixed brush 39 is located above the lower end of the wheel 38. The surface of the fixed brush 39 is subjected to fluororesin processing (for example, PTFE processing). In the present embodiment, the entire surface of the fixed brush 39 is treated with fluororesin. The fluororesin processing may be impregnated into the fixed brush 39.

Next, the operation of the above embodiment will be described with reference to FIGS. 1 to 4.

At the time of cleaning, the user first connects the hose body 21 to the main body suction port 19 of the vacuum cleaner main body 12 via the connection pipe part 26, and the hand operation part 27 on the tip side of the hose body 21. The extension pipe 22 and the floor brush 23 are sequentially connected to each other. Therefore, the suction chamber 41 (suction port 42) of the floor brush 23 communicates with the suction side of the electric blower 15.

Next, when the floor brush 23 is placed on the floor surface and the user holding the grip portion 28 operates the predetermined setting button 29 in a state where power can be supplied from the power supply unit to the main body control unit and the electric blower 15. The main body control unit controls the input of the electric blower 15 according to the operation mode set by the setting button 29, and the electric blower 15 is driven.

Further, by moving the floor brush 23 back and forth on the floor surface, the user sucks dust together with air from the suction port 42 on the tip side of the floor brush 23 by the action of the negative pressure generated by the drive of the electric blower 15. .. At this time, the fixing brush 39 is moved back and forth in contact with the floor surface to wipe off dust on the floor surface.

Then, the sucked air becomes a suction wind, and dust is carried from the floor brush 23 to the dust collecting part 18 from the main body suction port 19 through the extension pipe 22 and the hose body 21, and the dust is collected by the dust collecting part 18. To collect.

After that, the suction air from which the dust has been removed is sucked into the electric blower 15, passes through the electric blower 15 and becomes exhaust air, and the vacuum cleaner main body is provided from an exhaust port (not shown) provided at the rear of the vacuum cleaner main body 12. It is exhausted to the outside of 12.

Further, the user appropriately rotates the rotating brush 33 according to the type of the floor surface. At this time, when the user operates the predetermined setting button 29, the motor 35 supplied with power from the vacuum cleaner main body 12 side via the wiring is driven by the control unit in response to the operation of the setting button 29, and the motor 35 is driven by the control unit. The rotational force of the rotary brush 33 is transmitted via the timing belt, and the rotary brush 33 is rotated at high speed. Therefore, the bristle brush 52 of the rotating brush 33 assists in cleaning such as scraping out dust on the floor surface and polishing the floor surface.

Specifically, as shown in FIG. 1, the floor brush 23 does not sink into the relatively hard flat floor surface F1 such as flooring, and the tips 61b, 62b of the bristle brushes 61, 62, 63 do not sink. ， 63b slides in contact with the floor surface F1 to wipe off the dust adhering to the floor surface F1 and polish the floor surface F1. At this time, the second and third bristles 62 and 63, which have a weaker waist and a higher arrangement density than the first bristles 61, come into soft contact with the floor surface F1 and dust without damaging the floor surface F1. Can be wiped off.

Further, for a soft floor surface F2 such as a rug, the floor brush 23 sinks so that the tips 62b and 63b of the second and third bristles 62 and 63 penetrate deeply into the floor surface F2. The first bristle brush 61, which is stronger than the second and third bristle brushes 62 and 63, enters the floor surface F2 to a position closer to the base end portion 61a, and firmly collects dust that has entered the depths of the floor surface F2. Can be scraped out.

At this time, in the present embodiment, the rotary brush 33 is provided with a first bristles 61 and a second bristles 62 whose tip side protrudes in the radial direction from the first bristles 61, and these bristles are set. Since the entire brushes 61 and 62 are processed with fluororesin, the friction on the surface of the bristles 61 and 62 is reduced, making it difficult for dust to adhere to these bristles 61 and 62, or easily removing the attached dust. Will be possible. Therefore, the rotating brush 33 can be kept clean for a long period of time without complicated maintenance. Moreover, since the friction between the bristles 61 and 62 is reduced and the friction with the floor surface is reduced, the bristles are less likely to hurt (less wear) even if they are in contact with the floor surface. The diameter can be reduced, and dust on the floor surface such as flooring can be removed softly and reliably.

Further, although the first bristles 61 are stiffer than the second bristles 62, since the first bristles 61 are treated with a fluororesin, the first bristles 61 are stiff even if they are stiff. However, it becomes slippery with respect to the floor surface and is less likely to damage the floor surface.

In addition, since the second bristles 62, which have a higher density than the first bristles 61, are treated with fluororesin, the densely packed bristles can be brought into contact with the floor surface more softly, and the floor surface can be touched. Can be wiped off effectively.

Moreover, since the third bristle brush 63, which is further provided in the rotating brush 33, is also treated with fluororesin, the densely packed bristles can be brought into contact with the floor surface more softly, and the floor surface can be effectively brought into contact with the floor surface. Can be wiped off.

Since it is possible to prevent dust from adhering to the bristles 61, 62, 63 in this way, it is possible to use a bright color as the color design of the bristles 61, 62, 63, which was conventionally conspicuous due to the adhesion of dust. , You can improve the appearance.

Furthermore, since the hair brushes 61, 62, and 63 can be made water-repellent by fluororesin processing, for example, even when the rotating brush 33 is washed with water to remove dust, the water drainage is improved and the hair brush is drained. 61, 62, 63 are dried in a short time and ready to use.

Then, by providing the above-mentioned rotating brush 33 on the case body 31, it is possible to provide a clean and easy-to-use floor brush 23.

Further, at least one of the tips 61b and 62b of the bristles 61 and 62 (in this embodiment, the tips 61b, 62b and 63b of all the bristles 61, 62 and 63) is attached to the contact portion 46a of the case body 31. By contacting, at least one of the bristles 61 and 62 (all bristles 61, 62, 63 in this embodiment) is struck against the contact portion 46a by the rotation of the rotary brush 33, and dust can be removed by the impact. ..

Similarly, at least the tip 62b of the second bristles 62 (in this embodiment, the tips 61b, 62b, 63b of all the bristles 61, 62, 63) is placed behind the front cover 45 of the case body 31. By moving (rotating) the front cover 45, the rotation of the rotating brush 33 causes at least the second bristle brush 62 (all the bristle brushes 61, 62, 63 in the present embodiment) to come into contact with the front cover 45. It is struck by 45, and the impact can remove dust.

By providing the case body 31 with the fixing brush 39 processed with a fluororesin, the friction on the surface of the fixing brush 39 is also reduced, and it becomes difficult for dust to adhere to the fixing brush 39, or the attached dust can be easily removed. In addition to being able to be removed, friction due to the fixed brush 39 that is in constant sliding contact when traveling on the floor surface can be reduced, the traveling performance of the floor brush 23 can be improved, and wear of the fixed brush 39 can be suppressed.

In the above embodiment, the fluororesin processing of the bristles 61, 62, and 63 may be applied to at least a part of each. For example, the tip portion 61b of the first bristles 61 may not be treated with a fluororesin. In this case, the contact resistance of the tip portion 61b of the first bristle brush 61 is relatively increased to facilitate the scraping of dust, and the base end portion 61a is processed by fluororesin to reduce the contact resistance. Dust that has entered the end 61a side can be easily removed. Moreover, the first bristles 61 are treated with a fluororesin except for the tip portion 61b, so that when the first bristles 61 enter between the bristles of the bristles, the bristles of the rug and the first bristles 61 Resistance is less likely to occur due to rubbing against parts other than the tip 61b of the bristles 61. That is, the dust that has entered deep into the carpet can be scraped up firmly by the first bristles 61, and the first bristles 61 are less likely to rub against the bristles of the carpet and cause resistance, and enter between the bristles of the carpet. Because it is easy, it is easy to remove dust that has entered the deep position of the carpet.

Further, the bristle brush 52 may have two types or four or more types as long as it includes one bristle brush and another bristle brush longer than this one bristle brush.

Further, the electric vacuum cleaner 11 is not limited to the canister type, but is also compatible with, for example, a so-called upright type in which the connection pipe 32 of the floor brush 23 is connected to the lower part of the vacuum cleaner body 12 which is vertically elongated in the vertical direction. Can be used.
