自走式掃除機に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-propelled cleaner having a cleaning function and a moving function, which cleans a floor surface while the main body is self-propelled on the floor surface.

掃除機の開発も行なわれている。2. Description of the Related Art Conventionally, a vacuum cleaner has been developed in which a moving function is added to the vacuum cleaner to improve operability during cleaning. In recent years, in particular, a so-called self-supporting induction type self-propelled vacuum cleaner has been developed in which a microcomputer and various sensors are mounted on it to move and clean the cleaning place while judging by itself.

集めるサイドブラシ装置を備えたものもある。This type of self-propelled cleaner has a drive device such as a drive wheel and a drive motor as a moving function, an obstacle detecting means for detecting an obstacle at the time of movement, and a position for recognizing a moving position. It is usually equipped with recognition means,
As a cleaning function, it is equipped with an electric blower and a dust collecting device such as a suction nozzle provided at the bottom of the main body. Also, in order to improve the cleaning ability of the walls and the corners of the room, there is also a side brush device that rotates the rotating brush horizontally on the side of the main body and collects dust on the floor in the center of the main body. .

体の走行性の面ですぐれているからである。In a self-propelled vacuum cleaner equipped with such a side brush device, the rotary brush of the side brush device is arranged at a corner of the front part of the main body from the viewpoint of cleanability, and the suction nozzle is located immediately behind it, that is, on the side. It is usually located between the rotating brush and the rear wheel of the brush device. this is,
By arranging the suction nozzle between the rotating brush of the side brush device and the rear wheel, it becomes difficult for the suction nozzle to contact obstacles such as walls and pillars when the main body turns, which is excellent in terms of running performance of the main body. Because there is.

に部品交換できることが不可欠となるものである。However, there is a problem in considering such a conventional self-propelled cleaner in terms of repairability and maintainability. That is, the body weight is 10
If the weight is 20 kg or less, it can be repaired or maintained by overturning or reversing the main body like a normal household vacuum cleaner, and there is no particular problem. However, in a self-propelled vacuum cleaner intended for commercial use, the storage battery used as a power source becomes large due to the usage time, and the main body weight is 5
It is usually 0 to 100 kg or more. Therefore, it is difficult to turn over and turn over the main body, and it may be dangerous if the storage battery is installed. In other words, in the case of a large-sized self-propelled vacuum cleaner for business use, it is indispensable to replace parts without turning over the main body.

性・メンテナンス性が悪いものである。[0006] For example, the suction nozzle is a component that requires the most maintenance such as elimination of clogging of dust, replacement of an agitator, and replacement of a belt. However, like a conventional self-propelled cleaner, a suction brush is used as a rotary brush of a side brush device. If the structure is arranged between the rear wheels, it is very difficult to remove and the repairability and maintainability are poor.

分解が必要になり修理性・メンテナンス性が悪かった。Further, the electric blower, which has many opportunities for repair and maintenance in terms of life and failure, is not considered to be easily removed by the conventional self-propelled cleaner, and it requires extensive disassembly of the main body for repair. It was not easy to maintain and maintain.

Further, as shown in FIG. 2, the trolley portion 1a constituting the main body 1 of the present embodiment has a substantially trapezoidal plan shape in which the front width L f is larger than the rear width L r , and the trolley portion 1a has a rear end. The width L n of the suction nozzle 16 is substantially equal to the rear width L r . Therefore, when the main body 1 cleans the wall ridges parallel to the wall, the rotary brush 6 that constitutes the side brush device 5 is used.
Means that while rotating in the direction of arrow C, the outer tip end is applied to the wall edge to collect the dust inside the main body 1, and the suction nozzle 16 later sucks and collects the dust at a position slightly separated from the wall. Therefore, even if the main body 1 turns, the suction nozzle 16 does not hit the wall surface to prevent the main body 1 from traveling.

By providing the suction nozzle 16 having a width L n substantially equal to, even if the rotary brush 6 takes the locus of movement of the wall, the movement locus of the suction nozzle 16 becomes a position slightly separated from the wall of the suction nozzle 16 and the suction nozzle 16 and the wall surface. There is a margin between them. Therefore, the suction nozzle 16 can be easily attached and detached without sacrificing the traveling property, and a self-propelled cleaner having excellent repairability and maintainability is realized.

Also starts rotating. When the nozzle motor 35 starts rotating, the cleaning agitator 17 and the mark erasing agitator 18 are also rotationally driven. When the cleaning agitator 17 rotates, the brush 17a works to scrape up the dust while being pushed into the carpet surface. Therefore, the dust on the back side of the carpet surface floats on the surface, is sucked by the electric blower 8, passes through the connection pipe 19, and is accumulated in the filter 15 made of a paper bag in the dust collecting chamber 12. On the other hand, when the main body 1 runs on the carpet, the drive wheels 2 push down the hairs of the carpet due to the weight of the main body 1. However, in this embodiment, the mark erasing agitator 18 is rotated, and the fluff of the pushed carpet is raised again. In other words, the brush 18a acts so as to lift the bristles that are difficult to fold and fall on the carpet surface.
