In this type of self-propelled vacuum cleaner, the direction of movement is determined by, for example, connecting a rotary encoder to the left and right running wheels to measure the travel distance from the number of rotations of the running wheels. Usually, obstacles are avoided using distance sensors or the like. Some models still have a gyro sensor, such as a gas lever gyro, added to them to more reliably measure the direction of movement. As for the cleaning function, some are equipped with an electric blower to suck up dirt from the floor, and some are equipped with a rotating brush to sweep the floor.

Problems that the invention aims to solve: Self-propelled vacuum cleaners like this can be used in gymnasiums, hotel lobbies,
It was developed for the purpose of automatically cleaning large areas of corridor rings, and once it is placed in the cleaning area, it will make all the decisions on its own and move throughout the cleaning area without any human intervention. It is advisable to complete the cleaning. However, in reality,
Even if the floor is flat, for example, telephone wires on the floor or a protrusion of just a few centimeters can easily get over and stop, or even if you do get over it, the direction of movement will change and you may misjudge the position and clean it. There was a problem with leaving things unfinished. In particular, in the case of an electric blower that sucks up dirt from the floor through a suction nozzle, the suction nozzle is very close to the floor, so the above-mentioned protrusions often get caught in the suction nozzle.

そこで、本発明はたとえ床面にこのような凸部等の障害

Therefore, even if there is an obstacle such as a convex part on the floor surface, the present invention prevents the suction nozzle from getting caught and stopping, or leaving an uncleaned part due to incorrect position judgment. The present invention provides a self-propelled vacuum cleaner.

Means for Solving the Problems The technical means of the present invention for solving the above-mentioned problems is to support the suction nozzle on the main body via a spring, and to configure it so that it can move up and down with respect to the main body.

Effect: This technical measure allows the suction nozzle to rise upwards and escape from the floor under only a slight force. Therefore, on a flat floor, a certain distance is maintained between the suction nozzle and the floor, but if an obstacle such as a convex part of the floor comes under the suction nozzle, the suction nozzle will escape upwards due to the reaction. The main body can be moved smoothly without getting caught.

5. 5 is an electric blower that generates air suction force, and 6 is a filter disposed on the suction side of the electric blower, which is located inside the dust collection chamber 7. Reference numeral 8 denotes a suction nozzle that sucks in dirt ε on the floor surface, and communicates with the dust collection chamber 7 via a nozzle vibrator 9 and a bellows hose 1°. 11 is a check valve that prevents the dust collected in the dust collection chamber 7 from flowing back. In addition, the two nozzle receivers fixed in the main body 1 of the nozzle vibrator 9 are inserted through the plates 12M and 12B, and the hook provided on the nozzle pipe 9 is inserted into the claw 13.
The nozzle receiver is supported in a suspended state by the plate 12A via a spring 14 having one end fixed to the spring 14. FIG. 3 shows a detailed view of the surrounding area of the suction nozzle 8. The upper end of the spring 14 has a nozzle receiver fixed to the plate 12, and a hook fixed to the member 12'.

16 is a flexible membrane made of a rubber plate or the like fixed to the rear side of the suction nozzle 8, and its lower end abuts against the floor surface A to prevent air leakage from the rear of the suction nozzle 8 and improve the suction capacity. Reference numeral 16 designates a power source such as a lead-acid battery or dry cell battery, and reference numeral 17 designates a movement control circuit that independently controls the drive motors 3R and 3L to perform running and steering control such as going straight and changing direction. 18
Bumpers F and 18R are attached to the front and rear sides of the main body 10, respectively, to buffer the impact in the event of a collision, and at the same time stop the movement of the main body 1 by means of a pressure-sensitive switch (not shown) provided inside.

When this self-propelled vacuum cleaner is placed in the cleaning area, the running wheels 2R,
2L is driven by drive motors 3R and 3L and begins to move in the direction of arrow B. At this time, the drive motors 3R and 3L are controlled through the movement control circuit 17 by signals from an obstacle detection device, a position detection device, etc. (not shown in the figure), and the drive motors 3R and 3L are repeatedly moved straight, stopped, and changed direction while moving the entire cleaning area. Move 77, - move. During the movement, the electric blower 5 is activated, and the dust on the floor is sucked up through the suction nozzle 8 and transferred to the nozzle pipe 9. The dust is collected into the dust collection chamber 7 through the bellows hose 1o and cleaned.

ここで、例えば第3図に示すように、移動中に床面凸部

For example, as shown in FIG. 3, when the floor protrusion A' approaches from the front of the suction nozzle 8 and hits the front side surface 8' of the suction nozzle during movement, the suction nozzle 8 is forced to move in the direction of the arrow C. However, since the front side surface 8' has an angle θ with respect to the vertical direction, a reaction force is generated in the direction of the arrow, and the suction nozzle 8 escapes upward. Therefore, the main body 1 can smoothly move on the floor protrusion A' without getting caught by the suction nozzle 8.

次に本発明の他の実施例について説明する。Next, other embodiments of the present invention will be described.

FIG. 4 shows the surrounding area of the suction nozzle 19 of another embodiment, where 9 is a nozzle pipe, 15 is a flexible membrane, and other parts not shown in other countries are the same as those in the previous embodiment.

In this embodiment, a roller 20 having a length approximately equal to the overall width is rotatably attached to the lower front surface of the suction nozzle 19 on a rotating shaft 21 having both ends fixed to both sides of the suction nozzle 19. This roller 20 does not come into contact with the floor surface when the floor surface is flat, and has a gap G, so that it can suck up dust in front.

Further, the front plate 19' of the suction nozzle 19 forms a wall at the rear of the roller 20 to prevent air leakage from above the roller 20.

The self-propelled vacuum cleaner configured as described above moves on the floor surface, and as shown in FIG.
When the roller 2o approaches the roller 20 and hits the roller 20, the roller 2o rotates in the direction of the arrow F and rolls on the convex portion A', and the suction nozzle 19 receives the force in the direction of the arrow and escapes upward. Therefore, the suction nozzle 19 does not get caught on the protrusion A' and prevent the main body 1 from moving. By having the roller 20 in this way, if it is made of a material such as rubber, it can also serve as a cushioning material, and since the rolling of the roller 20 is utilized, the projection can be made more smoothly than in the previous embodiment. You can overcome part A'.

In this way, the present invention supports the suction nozzle on the main body via a spring and is configured to be able to move up and down with respect to the main body, thereby preventing the suction nozzle from getting caught on obstacles such as convexities on the floor. To provide a self-propelled vacuum cleaner that does not stop while moving in a cleaning area or leave cleaning unfinished due to misjudgment of position.
