DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a self-propelled vacuum cleaner that has a cleaning function and a moving function and that cleans a floor surface.

2. Description of the Related Art Conventionally, vacuum cleaners have been developed in which a moving function is added to the vacuum cleaner to improve operability during cleaning.

Particularly recently, so-called self-propelled self-propelled vacuum cleaners have been developed, which are equipped with various microcomputer sensors to clean while making decisions about where to clean on their own. .

This type of self-propelled vacuum cleaner connects a rotary encoder, etc. to the left and right running wheels, measures the moving speed and distance from the rotation speed of the running wheels, determines the moving direction, and emits ultrasonic waves etc. around the main body. Usually, obstacles are avoided using an obstacle detection sensor. Additionally, some devices are equipped with a gyro sensor such as a gas rate gyro for measuring the direction of movement.

Problems to be Solved by the Invention However, since rotary encoders use rotary encoders to measure travel speed and travel distance from the number of rotations of the running wheels, it is difficult to measure travel speed and travel distance when the diameter of the travel wheels changes. This will cause an error. Since this error is cumulative, as the moving distance increases, the error accumulates, making it impossible to determine the position, leading to unfinished cleaning and malfunctions. In particular, in the case of self-propelled vacuum cleaners, it is necessary to use pneumatic tires for the running wheels to avoid damaging the moving surfaces such as floors and carpets.
A unique problem was that the diameter of the running wheels was easily changed because the weight and center of gravity changed.

このため重心が変わり左右の走行輪の径にアンバランス
が生じた場合には、左右の走行輪の回転数が同じで本来

合も誤差の累積があり正確な誘導は困難であった。
For this reason, if the center of gravity changes and an imbalance occurs in the diameters of the left and right running wheels, the rotation speed of the left and right running wheels is the same, and the course that should normally be traveling in a straight line deviates to the left or right, causing a problem where control becomes impossible. It had become. Furthermore, in those that use a gyro to control direction, there is a drift peculiar to the gyro, and when used continuously for a long time, the direction gradually shifts, and in this case too, errors accumulate, making accurate guidance difficult.

The present invention provides a self-propelled vacuum cleaner that moves by self-guided guidance even when the diameter of the running wheels changes, and thoroughly cleans the moving surface without damaging it.

Operation With this configuration, the moving speed of the self-propelled vacuum cleaner main body is detected as the outer circumferential speed of the steering and driving wheels, and the moving speeds of the left and right sides of the main body are detected to measure the moving distance and moving direction. Therefore, since the moving speed and distance are not measured indirectly from the rotation speed of the running wheels, the diameter of the running wheels is irrelevant, and self-supporting guidance can be achieved even if the self-weight and center of gravity change depending on the amount of cleaning, and the diameter of the running wheels changes. The moving surface can be reliably cleaned without damaging the moving surface.

When the moving speed is fast, the output signal pulse becomes short, and when the vehicle is moving straight, the number of pulses on the left and right sides is the same, so the signal as shown in 27 is obtained. Similarly, 28 is a signal when the moving speed is slow and is moving straight, and 29 is a signal when the right side is moving slowly and rotating to the right because the signal pulse from the outer peripheral speed detection means on the right side of 16R is long. This is the signal.

For example, if the self-propelled vacuum cleaner according to this embodiment is placed at a cleaning place as shown in FIG.
Obstacle detection sensors 17, 17 installed on the left and right sides
Cleaning is performed while moving the moving surface A along the surrounding wall C as shown by the arrow, while detecting the surrounding wall C with ', 18, 18', 19, and 19'. At this time, a pair of outer peripheral speed detection means 16 attached to the left and right sides of the main body 1
The distance and direction of movement are measured by detecting the speed with respect to each moving plane A during movement using L and 16R, and are sequentially stored in a storage circuit provided in the judgment processing circuit 15. Therefore, when the robot goes around the surrounding wall C and returns to the original location, the shape and size of the cleaning location are stored in the memory circuit.

When moving straight, the outer peripheral speed detection means 16L and 16R control the left and right movement distance of the main body 1 to be the same, so even if the moving surface A is uneven and the direction of the main body 1 changes, it will always move straight. The direction can be modified as desired. When the vacuum cleaner approaches the next opposing wall C2 to a certain distance, it again changes direction by 90' as shown by arrow F, and repeats the above operation, until it reaches arrow G in FIG.
As shown in the figure, the cleaning area can be thoroughly cleaned.
