Abstract

PROBLEM TO BE SOLVED: To provide a vacuum cleaner that is simple in structure and can be conveniently used also manually. SOLUTION: A suction opening body 20 is connected to a connecting pipe 4 for automatic cleaning. A traveling wheel 12 is driven by a control circuit 9 through a motor, and makes a body case 2 autonomously travel. An electric blower 6 is driven and dust is sucked from the suction opening 21. For manual cleaning, when a hose is connected to the connecting pipe 4, a connection sensor 31 detects the connection of the hose. A magnetic clutch turns off the driving of the traveling wheel 12 by the motor, and the output of an electric blower 6 is increased by a dust suction control circuit 7. Dust is sucked from the suction opening 21. When the distance between the body case 2 and an obstacle becomes shorter than a prescribed distance, the control circuit 9 drives the traveling wheel 12 through the motor to make the body case 2 avoid an obstacle. When the distance between the body case 2 and the hose becomes longer than a prescribed distance, the control circuit 9 drives the traveling wheel 12 through the motor to bring the body case 2 closer to the hose.

After that, when the battery pack 8 supplies electric power to the electric blower 6 and the control circuit 9 to drive it, the control circuit 9 controls the driving of the traveling wheels 12 via the motor 14 and the main body. Case 2 runs on its own.

At this time, when the distance between the main body case 2 and the obstacle detected by the sensor 10 is shorter than a predetermined distance, the switching means 15 causes the magnetic clutch 13 to turn on the drive of the traveling wheels 12 by the motor 14. The control circuit 9 drives the traveling wheels 12 via the motor 14 to avoid the main body case 2 from obstacles.

Then, by driving the electric blower 6, dust on the surface to be cleaned is sucked from the suction port 21. The sucked dust is carried to the dust collection case 5 and filtered by a dust collection filter (not shown).

When the surface to be cleaned is a carpet or the like, the rotary brush 22 is rotated by the motor 23 and driven to scrape dust from the carpet and suck the dust from the suction port 21.

Even during this manual cleaning, when the distance between the main body case 2 and the obstacle detected by the sensor 10 becomes smaller than a predetermined distance, the switching means 15 causes the magnetic clutch 13 to drive the traveling wheels by the motor 14. When the drive of 12 is turned on and the control circuit 9 drives the traveling wheels 12 via the motor 14, the main body case 2
To avoid the obstacles.

Similarly, when the cleaner moves the hose body 30 and the distance between the distance sensor 32 and the distance sensor 33 becomes larger than a predetermined distance, the switching means 15 causes the magnetic clutch 13 to move.
The drive of the traveling wheels 12 by the motor 14 is turned on, and the traveling wheels 12 are driven by the control circuit 9 via the motor 14 to bring the main body case 2 close to the hose body 30.

As a result, it is not necessary to separately switch the magnetic clutch 13 when cleaning manually, and malfunctions such as manual cleaning while the traveling wheels 12 are automatically controlled are prevented and the usability of the electric vacuum cleaner 1 is improved. .

Further, even during manual cleaning, the sensor 10 detects the distance between the main body case 2 and the obstacle, and when the main body case 2 approaches the obstacle, the switching means 15 causes the magnetic clutch 13 to move. Then, the drive of the traveling wheel 12 by the motor 14 is turned on, and the traveling wheel 12 is driven by the control circuit 9 via the motor 14 to avoid the main body case 2 from an obstacle, so that the cleaner moves the main body case 2. There is no need to avoid obstacles, and the labor of cleaning is reduced and cleaning is easy.

As a result, even during manual cleaning, the main body case 2 automatically follows the direction of movement of the cleaner, so that the cleaner does not have to move the main body case 2, and the cleaning device is the same as the cleaning device shown in FIGS. It is possible to obtain the action and effect.

Further, the sensor 40 detects the direction of the force applied to the connecting pipe 4, and when this force is larger than a predetermined magnitude, the switching means 15 turns on the drive of the traveling wheel 12 by the motor 14 by the magnetic clutch 13. Then, the control circuit 9 drives the traveling wheels 12 via the motor 14 to move the main body case 2 by a predetermined distance in the direction of force, so that the main body can be easily and surely moved in the direction in which the hose body 30 is moved by the cleaner. Case 2 can be moved.

Moreover, since the sensor 40 alone can achieve the same effect as the distance sensor 32 and the distance sensor 33 of the cleaning device shown in FIGS. 1 to 5, the cleaning device shown in FIG. 6 has a simpler structure. The usability can be improved.

Although the rotary brush 22 is attached to the suction port 21 in each of the above-described embodiments, the rotary brush 22 and the motor 23 for driving the rotary brush 22 are eliminated as long as the dust can be efficiently absorbed. May be.

For manual cleaning, the connecting pipe 4

Further, the notch 3 may be provided only on the bottom plate 2a of the main body case 2. At this time, since the connecting pipe 4 is located on the lower surface of the main body case 2, if the hose body 30 is connected during manual cleaning, the hose body 30 may contact the surface to be cleaned and prevent movement of the main body case 2. There is also. In this case, clean the main body case 2 in an upright state, clean while holding the grip bar (not shown) provided on the top of the main body case 2, or use the slide type grip (not shown) provided on the main body case 2. While holding it, it is pulled to clean it, or the main body case 2 is carried on its back with a belt (not shown) attached to the main body case 2 for cleaning.
