Controls the drive of the electric blower 13, the brush motor 29, and the turning motors 44, 44 while controlling the drive so that the main body case 12 (the vacuum cleaner 11) travels autonomously so as to avoid the obstacle W. Thus, the vacuum cleaner 11 can be cleaned.
- the secondary battery 23 (FIG. 3) supplies power to the control unit 22, the electric blower 13, the distance measuring sensor 18, the brush motor 29, the motors 36 and 36, the turning motors 44 and 44, and the like.
- the secondary battery 23 is disposed, for example, at a position between the drive wheels 15 and 15 behind the turning wheel.
- the secondary battery 23 is electrically connected to a charging terminal located on the lower surface 25 of the main body case 12.
- the secondary battery 23 is connected to a predetermined charging stand (not shown) installed at a predetermined position in a room (room). Thus, charging is possible by connecting the charging terminal.
- the driving wheels 15 and 15 When the vacuum cleaner 11 is placed on the surface to be cleaned, the driving wheels 15 and 15 come into contact with the surface to be cleaned, and the driving wheels 15 and 15 are energized by the suspension means (suspension part) by the weight of the vacuum cleaner 11.
- the driven wheel 17 (swivel wheel 39) sinks into the body case 12 together with each gear box to a position where it contacts the surface to be cleaned. Then, for example, when the predetermined time preset in the control unit 22 is reached, the electric vacuum cleaner 11 drives the electric blower 13 and starts cleaning from the charging stand, for example.
- the cleaning start position can be set at an arbitrary place such as the travel start position of the electric vacuum cleaner 11 or the entrance / exit of the room.
- the control unit 22 drives the electric blower 13, and the motors 36 and 36 are connected to the surroundings of the cleaning area, for example, obstacles W in the cleaning area, etc. via the distance measuring sensor 18.
- the position and the running state of the electric vacuum cleaner 11 are monitored by detecting the distance between and the distance to the surface to be cleaned while avoiding the obstacle W in response to the detection from the distance measuring sensor 18.
- the control unit 22 rotates each side brush 19 via each turning motor 44 or drives the rotating brush 28 via the brush motor 29 as necessary.
- each side brush 19 has a contact surface 46 of the brush body 41 protruding outward from the outer peripheral surface 34 (outer envelope surface) of the main body case 12.
- Each of the cleaning bodies 43 projecting from the swivel portion 48 provided at the tip of each of the heads extends to the surface to be cleaned near the obstacle W such as a wall, and the swivel motor 48 is swung by the swivel motor 44, thereby obstructing the obstacle.
- the dust on the surface to be cleaned in the vicinity of W is scraped off (FIG. 1 (a)).
- the control unit 22 advances one drive wheel 15 by one motor 36.
- the direction of the vacuum cleaner 11 (main body case 12) turning at that position (super turning) by driving in the direction and driving the other driving wheel 15 in the reverse direction by the other motor 36 Change the forward direction).
- the contact surface 46 of the brush main body 41 of the side brush 19 that protrudes outward from the outer peripheral surface 34 (outer envelope surface) of the main body case 12 is obstructed.
- the main body case 12 contacts (collises) relative to the object W in the turning direction of the main body case 12, that is, the direction T along the tangent line of the outer peripheral surface 34 of the main body case 12.
- the cleaning body 43 protruding outward from the contact surface 46 bends in a direction opposite to the turning direction of the main body case 12 by contact with the obstacle W. Does not interfere with contact. Since the contact surface 46 has a shape along the circular arc, the external force acting on the contact surface 46 of the side brush 19 from the obstacle W is applied to the outer periphery of the main body case 12 as the main body case 12 further rotates.
- the brush body 41 is inward of the body case 12, and the outer side or outer surface of the contact surface 46 of the brush body 41 is the outer periphery of the body case 12.
- the outer peripheral surface 34 (the outer peripheral surface 34) of the brush body 41 (side brush 19) until the surface 34 (substantially the envelope surface including the outer peripheral surface 34 (along the outer peripheral surface 34)) is substantially the same position.
- the brush main body 41 is caught by the obstacle W to prevent the main body case 12 from turning, since the amount of protrusion from the virtual envelope envelope surface (along the outer peripheral surface 34) is approximately zero. There is nothing (Fig. 1 (b)).
- the brush main body 41 returns to the outside of the main body case 12 by the biasing force of the coil spring 42, and the contact surface 46 This is again the position protruding outward from the outer peripheral surface 34 (outer envelope surface) of the main body case 12. Further, since the cleaning body 43 bent in the opposite direction to the turning direction of the main body case 12 due to contact with the obstacle W has elasticity, the contact with the obstacle W is released to return to the original state. And return deformed.
- the vacuum cleaner 11 sucks dust on the surface to be cleaned or dust collected by the side brushes 19 and 19 together with air through the suction port 27 to which the negative pressure generated by driving the electric blower 13 is applied. . Further, the rotary brush 28 that is driven to rotate scoops up dust on the surface to be cleaned from the suction port 27.
- Dust sucked from the suction port 27 or dust picked up by the suction port 27 is introduced and collected in the dust collecting section 14, and the air from which the dust has been separated is sucked into the electric blower 13, and this electric motor After cooling the blower 13, exhaust air is exhausted from the exhaust port 26 to the outside of the main body case 12.
- control unit 22 causes the vacuum cleaner 11 to autonomously travel to the position of the charging stand, stops the electric blower 13 and the like, and sets the charging terminal on the charging stand (physical And the motors 36, 36, etc. are stopped, the operation is terminated, and the secondary battery 23 is charged.
- the outer shell (contact surface 46) on the distal end side of the brush main body 41 that protrudes outward from the outer peripheral surface 34 of the main body case 12 and is exposed is formed along the arc. Therefore, the appearance of the brush body 41 is good, and when the external force in the direction T along the tangent line of the outer peripheral surface 34 of the main body case 12 acts on the contact surface 46, the brush main body 41 causes the direction of the external force to be changed by the contact surface 46.
- the brush main body 41 can be easily moved in this direction by converting to the direction of retracting toward the outer peripheral surface 34 side of the case 12. Therefore, for example, even when the contact surface 46 of the side brush 19 is in contact with the obstacle W in the direction T along the tangent line when the main body case 12 is turned, the side brush 19 can be retracted more easily and reliably. .
- the outer shell (contact surface 46) on the tip side of the brush body 41 may have a substantially triangular shape in plan view.
- the contact surface 46 is relatively inclined to connect the contact portions 46a, 46a, which are inclined portions that are curved in a relatively large-diameter arc shape and bulge outward, and the contact portions 46a, 46a.
- the continuous portion 46b curved in the shape of a small-diameter arc forms a so-called Rouleau triangle (a rice ball shape).
- the triangular shape may be a triangular shape in which the contact portions 46a and 46a are planar, and includes a shape in which the contact portions 46a and 46a are bulged outward as described above.
- the direction of the contact portion 46a (the direction of the tangent to the contact portion 46a) is inclined so that the angle ⁇ with respect to the direction T along the tangent to the outer peripheral surface 34 of the main body case 12 is acute, preferably less than 45 °. .
- 46a when the external force in the direction T along the tangent to the outer peripheral surface 34 of the main body case 12 acts on the contact portions 46a, 46a of the contact surface 46, the external force is applied by the contact portions 46a, 46a of the contact surface 46.
- This direction is more reliably converted to a direction in which the brush body 41 retracts toward the outer peripheral surface 34 of the body case 12, and the brush body 41 can be easily moved in this direction. Therefore, for example, even when the contact surface 46 of the side brush 19 is in contact with the obstacle W in the direction T along the tangent line when the main body case 12 is turned, the side brush 19 can be retracted more easily and reliably. .
- the tip end side of the brush body 41 has a trapezoidal shape in which, for example, the contact portions 46a and 46a are connected by a flat continuous portion 46b, the same effect can be obtained.
- the main body case 12 may be provided with a contact type obstacle sensor or the like that detects the obstacle W by contacting the obstacle W, for example, on the outer peripheral surface.
- the side brush 19 may be disposed only on one side in front of the suction port 27 of the main body case 12.
- the electric blower 13 is not an essential configuration as long as dust can be lifted up from the suction port 27 to the dust collecting unit 14 by the rotating brush 28.
- the rotating brush 28 is not an essential component as long as the electric blower 13 can suck dust from the suction port 27 into the dust collecting portion 14.
- the brush motor 29 is also unnecessary and the configuration can be further simplified.
- outer peripheral surface 34 of the main body case 12 has a shape formed along an arc, it may be formed along, for example, a polygon (a quadrilateral or more).
- the vacuum cleaner 11 is a self-propelled type that autonomously travels while detecting an obstacle by the distance measuring sensor 18 or the like, but may be one that is remotely operated by a user using a remote controller, for example.
- the brush body 41 of the side brush 19 is crossed with respect to a predetermined direction (the radial direction of the body case 12) that is the moving direction of the brush body 41, that is, the body case.
- a predetermined direction the radial direction of the body case 12
