Abstract

PROBLEM TO BE SOLVED: To provide a vacuum cleaner which can efficiently clean up to the edge of a floor. SOLUTION: An outer peripheral suction port 4 is equipped along a part of the outer periphery in the vicinity of the outer periphery of the bottom plate part 2a of the main body case 2. When the main body case 2 approaches the vicinity of a wall, the edge of a floor, the right suction part 4b approaches the wall. Even when the main body case 2 is rotated, dust on a floor face in the vicinity of the wall is sucked by the electric blower through the right suction port 4b. The cleaner can efficiently clean up to in the vicinity of the wall, the edge of a floor, where dust easily accumulates. When the control circuit detects existence of a wall in the vicinity of the main body case 2 by a sensor, suction power through the right suction port is enhanced. When the main body case 2 reaches in the vicinity of a wall, the floor face can be efficiently cleaned up to the edge because more dust on the floor face is sucked through the right suction part 4b.

Traveling wheels for traveling the body case are attached to the body case. A motor is attached to the traveling wheels, and the traveling wheels and the motor constitute a moving means. Further, a suction port is opened at a substantially central portion of the bottom surface of the main body case, and the main body case 2 accommodates an electric blower as a dust suction means for sucking dust from the suction port.

In this cleaning device, the traveling wheels are driven by the motor to drive the main body case by itself, and dust is sucked from the suction port by driving the electric blower.

[0004]

However, in the above-mentioned cleaning device, since the suction port is opened substantially at the central portion of the bottom surface of the main body case, the main body case is a portion to be cleaned, such as a wall. Even if the suction port is approached, the suction port does not reach close to the wall, and it is difficult to clean the portion on the surface to be cleaned.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a cleaning device for efficiently cleaning a portion of a surface to be cleaned.

[0006]

According to a first aspect of the present invention, there is provided a cleaning device having a cleaner main body and an outer peripheral suction port provided near the outer peripheral surface of a bottom surface of the cleaner main body facing a surface to be cleaned along the outer periphery. And a dust suction means for sucking dust from the outer peripheral suction port, and a moving means for independently moving the cleaner body.

Since the outer peripheral suction port is provided in the vicinity of the outer periphery of the bottom surface of the cleaner body along at least a part of this outer periphery, the cleaner body can move independently in any direction. Since the dust on the surface to be cleaned is absorbed by the dust suction means from the outer peripheral suction port without changing the direction of the main body, the portion on the surface to be cleaned where dust easily collects can be efficiently cleaned.

According to a second aspect of the present invention, there is provided the cleaning apparatus according to the first aspect, wherein the obstacle detecting means detects an obstacle in the vicinity of the cleaner body and the obstacle detecting means detects the obstacle of the cleaner body. When an obstacle is detected in the vicinity, the control means is provided for increasing the suction force of the outer peripheral suction port located on the obstacle side.

Then, when the obstacle detecting means detects an obstacle in the vicinity of the cleaner body, that is, when the cleaner body is on the surface to be cleaned, the control means has an outer circumference located on the obstacle side. By increasing the suction force from the suction port,
When the main body of the vacuum cleaner comes close to the obstacle, more dust on the surface to be cleaned is sucked from the outer peripheral suction port located on the side of the obstacle. Make sure to clean the surface to be cleaned.

According to a third aspect of the present invention, in the cleaning apparatus according to the first aspect, the bottom surface of the cleaner body is substantially rectangular, and the cleaner body is attached near each corner of the bottom surface of the cleaner body and communicates with the dust suction means. A suction port body having a dust suction port, an obstacle detection means for detecting an obstacle in the vicinity of the cleaner body, and an obstacle detection means for detecting an obstacle in the vicinity of the cleaner body. And a control means for increasing the suction force from the dust suction port of the suction port body on the obstacle side.

The suction inlet is provided with a dust suction inlet near each corner of the substantially rectangular bottom surface of the cleaner body, and the control means is
When the obstacle detecting means detects an obstacle near the cleaner body, that is, when the cleaner body is on the surface to be cleaned, the suction force from the dust suction port of the suction port body on the obstacle side is enhanced. Let As a result, when the cleaner body comes near the obstacle on the surface to be cleaned, the suction force from the suction port body on the obstacle side is increased, and the obstacle on the surface to be cleaned where dust easily accumulates. Since the dust on the surface to be cleaned in the vicinity is sucked, the surface to be cleaned near the obstacle, which is the surface to be cleaned, is more surely cleaned.

According to a fourth aspect of the present invention, there is provided the cleaning apparatus according to the second or third aspect, wherein the control means detects the obstacle in the vicinity of the cleaner body by the obstacle detecting means.
The suction force is increased from at least one of the outer peripheral suction port on the front side in the traveling direction and the outer peripheral suction port on the rear side in the traveling direction of the cleaner body.

The control means, when the obstacle detection means detects an obstacle near the cleaner body, that is, when the cleaner body is on the surface to be cleaned, the front side in the traveling direction of the cleaner body. By increasing the suction force from the outer peripheral suction port on at least one of the rear side in the traveling direction and the cleaner body moves along the obstacle, dust is likely to accumulate on the surface to be cleaned. Not only the surface to be cleaned in the vicinity but also the surface to be cleaned along the obstacle can be cleaned while increasing the suction force from the outer peripheral suction port, so that the cleaning can be efficiently performed.

A cleaning device according to a fifth aspect is the cleaning device according to any one of the first to fourth aspects, in which the cleaning device is larger than the dust provided in the substantially central region of the bottom surface of the cleaner body and sucked from the outer peripheral suction port. It is provided with a central suction port through which dust can be sucked by the dust suction means.

Since the central suction port can suck dust larger than the dust sucked from the outer peripheral suction port by the dust suction means, the relatively large dust which is difficult to be sucked by the outer circumferential suction port is absorbed in the central suction port. The dust is sucked in to improve the cleaning efficiency.

A corner brush 5d is rotatably attached along the floor by closing the corner portion of the outer peripheral suction port 4 at the corner where the left suction portion 4d and the front suction portion 4a intersect. Here, these corner brushes 5a, 5b, 5c and 5d constitute the corner brush 5 which is a suction port body.

Further, each of the corner brushes 5a, 5b, 5c, 5d has a substantially circular dust collecting portion 6a, 6b, in the axial direction of the corner brushes 5a, 5b, 5c, 5d, that is, in the direction perpendicular to the floor surface. 6c and 6d are provided so as to penetrate therethrough, respectively, and these dust suction portions 6a, 6b, 6c,
6d constitutes the dust suction port 6. Further, the dust suction parts 6a, 6

A motor (not shown) is connected to 5b, 5c, 5d as a suction port driving means for rotating these corner brushes 5a, 5b, 5c, 5d along the floor surface. The corner brushes 5a, 5b, 5c, 5d are rotationally driven by these motors (not shown), and the brush body 7 scrapes out the dust on the floor surface 3 as the surface to be cleaned.
The dust thus scraped out is sucked from each of the dust suction portions 6a, 6b, 6c, 6d.

On the other hand, a substantially rectangular central suction port 10 is provided in a substantially central region of the bottom plate portion 2a. This central suction port 10
Is formed in a substantially square shape on the lower surface of the bottom plate portion 2a in a plan view, and is tapered upward, and the upper end is formed in a substantially rectangular shape having a longitudinal direction along the width direction of the main body case 2. .

Wheels 11 are coaxially opposed to each other and are attached so as to be rotatable and substantially symmetrical with respect to an imaginary centerline along the longitudinal direction. Further, a motor 12 is attached to each of the traveling wheels 11 as a drive means for driving the traveling wheels 11 to rotate. The traveling wheels 11 and the motor 12 constitute a moving means 13, and the moving means 13 allows the main body case 2 to run independently, that is, to run by itself. Further, a slewing wheel 14 as a moving direction setting means is rotatably attached in the longitudinal direction of the central suction port 10 in the bottom plate portion 2a. The slewing wheel 14 has a slewing wheel 14a on the front side of the main body case 2 and a slewing wheel 14b on the rear side of the main body case 2, and these slewing wheels 14a, 14b are virtual along the width direction of the main body case 2. It is attached at a position substantially symmetrical with respect to the center line. As a result, the vacuum cleaner 1
It becomes possible to run on the floor with the running wheels 11, and the turning wheels 14a, 14b
The moving direction is set by, and the traveling wheels 11 and the turning wheels 14a, 14b are symmetrically arranged with respect to the virtual center line, so that they are supported in a stable weight balance.

Further, inside the main body case 2 above the turning wheel 14a, a substantially rectangular dust collecting case 20 having a longitudinal direction along the width direction of the main body case 2 is attached. The dust collection case 20 includes an outer peripheral suction port 4, a dust suction port 6,
The central suction port 10 and the central suction port 10 are communicated with each other through a communication pipe 21 as an air passage. Further, on the upper side of the dust collection case 20 in the main body case 2, an electric blower 22 as a dust suction means that is connected to the dust collection case 20 and is driven by electric power is attached. Further, inside the main body case 2 above the slewing wheel 14b, a substantially rectangular parallelepiped battery pack 23 which is a power supply means as a secondary battery for supplying electric power to the electric blower 22 is attached. This electric blower 22 and the outer peripheral suction port 4,
A regulating valve 24 driven by electric power supplied from a battery pack 23 is connected to each of the communication pipes 21 between the dust suction port 6 and the central suction port 10.

On each outer surface of the cover 2b, a sensor 30 such as an infrared sensor or an image sensor as an obstacle detecting means is attached so as to face the outer surface of the cover 2b. The sensor 30 includes a sensor 30a attached to a front outer surface of the body case 2 in the traveling direction, a sensor 30b attached to a right outer surface of the body case 2 in the traveling direction, and a rear side of the body case 2 in the traveling direction. Sensor mounted on the outer surface of the
c, and a sensor 30d attached to the outer surface on the left side in the traveling direction of the main body case 2. On the inner surface of the front side of the cover 2b, the motor 12 is driven to
A control circuit 31 as a control means for driving the 11 to rotate is attached.

Next, each control of the above-mentioned one embodiment will be described.

As shown in FIG. 3, the control circuit 31 includes a regulating valve.
The opening amount of 24 is increased or decreased. In addition, this control circuit 31
Causes each sensor 30 to detect, for example, the wall 40 shown in FIG. 2 as an obstacle in the vicinity of the main body case 2.

When each sensor 30 does not detect the wall 40 in the vicinity of the main body case 2, the control circuit 31 increases the opening amount of only the adjusting valve 24 of the central suction port 10, and the central suction port 10 is controlled. Increase the suction force from.

On the other hand, as shown in FIG.
When the wall 40 as an obstacle is detected in the vicinity of the main body case 2 at 30b, that is, when the main body case 2 is on the floor surface 3, the control circuit 31 causes the right suction portion located on the wall 40 side.
By increasing the opening amount of the adjusting valve 24 of 4b, the right suction part 4b
In addition to increasing the suction force from, the corner brush 5a and the corner brush 5b is rotationally driven by a motor (not shown), to increase the opening amount of the adjustment valve 24 of the dust suction portion 6a and the dust suction portion 6b,
The suction force from the dust suction portions 6a and 6b is also increased.

Then, the control circuit 31 drives the motor 12 to rotate the traveling wheels 11 to move the main body case 2 along the wall 40 toward the wall 41 at a relatively slow speed. At this time, the control circuit 31 controls the front suction portion 4a, which is the front side in the traveling direction.
The opening amount of the adjusting valve 24 is also increased and the suction force from the front suction section 4a is also increased.

At the same time, the control circuit 31 reduces the opening amount of the adjusting valve 24 of the central suction port 10 to further enhance the suction force from the front suction portion 4a and the dust suction portions 6a, 6b.

Next, the operation of the above embodiment will be described.

First, the battery pack 23 supplies power to the control circuit 31 to operate the control circuit 31.

Next, the control circuit 31 controls the battery pack 23.
The electric blower 22 and the motor 12 are driven while adjusting the electric power supplied from the electric blower 22 to the motor 12 and the like.

Then, the traveling wheels 11 are driven to rotate by the drive of the motor 12, so that the main body case 2 is self-propelled.

By driving the electric blower 22, dust is sucked from the outer peripheral suction port 4, the dust suction port 6, and the central suction port 10, respectively.

Here, the sensor 30 detects the presence of the wall 40 in the vicinity of the main body case 2.

According to the positions of the wall 40 and the main body case 2 detected by the sensor 30, the control circuit 31 causes the outer peripheral suction port 4,
The suction force from the dust suction port 6 or the central suction port 10 is increased or decreased, respectively, and the motor 12 is driven to rotate the traveling wheels 11 to move the main body case 2 along the wall 40. At the time of 3, the dust on the floor surface 3 near the wall 40 is cleaned.

As described above, according to the above-described embodiment, the outer peripheral suction port 4 is provided in the vicinity of the outer periphery of the bottom plate portion 2a along the outer periphery thereof, so that when the main body case 2 approaches the wall 40. The right side suction part 4b located on the side of the wall 40 approaches the wall 40, and the dust on the floor surface 3 near the wall 40 can be sucked by the electric blower 22 from the right side suction part 4b. In any direction, the floor surface 3 near the wall 40, which is the floor surface 3, can be efficiently cleaned without changing the direction of the body case 2.

Further, for example, when the wall 40 is detected near the main body case 2 by the sensor 30b, that is, the main body case 2 is detected.
When the floor is on the floor 3, the control circuit 31 controls the regulating valve 24
The suction force from the right side suction portion 4b located on the wall 40 side is increased by adjusting the opening amount of the wall 40 to absorb more dust on the floor surface 3 near the wall 40. Floor 3 near
Can be cleaned more reliably. At the same time, the control circuit 31 rotatably drives the corner brushes 5a and 5b to scrape out the dust, and adjusts the opening amount of the adjustment valve 24 of the dust suction portion 6a and the dust suction portion 6b to adjust the opening amount of these dust suction portions 6a and 6b. In order to increase the suction force from the floor to suck dust from the floor surface 3 near the wall 40,
The floor surface 3 near the wall 40, which is near the floor surface 3, can be more reliably cleaned. Furthermore, when the main body case 2 moves along the wall 40 by adjusting the opening amount of the adjusting valve 24 by the control circuit 31 and increasing the suction force from the front suction portion 4a, the floor surface 3 near the wall 40 is also increased. Not only this, but also the floor surface 3 along the wall 40 can be cleaned, so that it can be cleaned more efficiently.

Since the central suction port 10 capable of sucking larger dust than the outer circumferential suction port 4 is provided, relatively large dust which cannot be sucked by the outer circumferential suction port 4 can also be sucked by the central suction port 10. Therefore, the cleaning efficiency can be improved.

Further, since the main body case 2 has a substantially rectangular parallelepiped shape, the main body case 2 can be inserted to a corner when cleaning a place where the wall 40 and the wall 41 are substantially orthogonal to each other as shown in FIG. Because it is easy, there is no dust left in the corner and the corner can be cleaned efficiently.

Further, since the outer peripheral suction port 4 is provided in the vicinity of the outer periphery of the bottom plate portion 2a, a space can be easily taken in the substantially central region of the bottom plate portion 2a, so that the central suction port 10 can be made relatively large.

In addition, since the main body case 2 is formed in a shape with rounded corners when viewed in a plan view, the corners are less likely to be caught by the wall 40 when the main body case 2 moves. The main body case 2 can move more smoothly, and the wall 40 can be less likely to be scratched.

Although the main body case 2 has a substantially rectangular parallelepiped shape in the above-described embodiment, the shape of the cover 2b may be substantially the same as that of the bottom plate portion 2a depending on the place to be cleaned. Other shapes that have a substantially rectangular opening,
The entire main body case 2 may be formed in, for example, a substantially polygonal columnar shape, a substantially cylindrical shape, or a substantially hemispherical shape.

The suction force from the outer peripheral suction port 4, the dust suction port 6, and the central suction port 10 may be adjusted only by opening and closing the adjusting valve 24. Further, a regulating valve 24 may be directly attached to the outer peripheral suction port 4, the dust suction port 6, and the central suction port 10 to increase or decrease the opening amount of the outer circumferential suction port 4, the dust suction port 6, and the central suction port 10. .

Alternatively, the suction force from the outer peripheral suction port 4, the dust suction port 6 and the central suction port 10 is directly adjusted by the electric blower 22 without providing the adjusting valve 24. The drive of the electric blower 22 may be adjusted by making it stronger or weaker by the control circuit 31 by connecting to the mouth 10.

Further, the corner brush 5 does not have to be rotated as long as dust can be scraped off the floor surface 3. Also, the dust suction port 6
Is the outer peripheral suction port 4 or the central suction port 10 to the corner brush 5
It need not be provided as long as the dust scraped out in can be sucked.

In addition, the corner brush 5 or the central suction port
10 may be omitted if dust can be sufficiently sucked from the outer peripheral suction port 4.

When the body case 2 moves along the wall 40, the suction force from the rear suction portion 4c, which is the rear side in the traveling direction, may be increased if the cleaning can be efficiently performed, and the front suction is performed. The suction force from both sides of the portion 4a and the rear suction portion 4c may be increased.

Further, when the sensor 30 detects the wall 40 in the vicinity of the main body case 2, the control circuit 31 drives the traveling wheels 11 via the motor 12 to temporarily stop the main body case 2 and set it in advance. The dust may be sucked at the same place for a predetermined time, or may be sucked while the body case 2 is reciprocated along the wall 40.

Further, the control circuit 31 rotationally drives only the corner brush 5a via a motor (not shown) when the sensors 30a and 30b detect the wall 41 and the wall 40, respectively, as shown in FIG. The opening amount of the regulating valve 24 of the dust suction portion 6a may be increased to enhance the suction force from the dust suction portion 6a.

When an obstacle is detected by the obstacle detecting means in the vicinity of the cleaner body, that is, when the cleaner body is on the surface to be cleaned, at least one of the front side and the rear side in the moving direction of the cleaner body. By increasing the suction force from the outer peripheral suction port on the side, when the cleaner main body moves along the obstacle, not only the surface to be cleaned in the vicinity of the obstacle, which is the case when the surface to be cleaned is likely to collect dust, Since the surface to be cleaned along the obstacle can be cleaned while increasing the suction force from the outer peripheral suction port, it can be cleaned efficiently.

According to the cleaning device of the fifth aspect, in addition to the effect of the cleaning device according to any one of the first to fourth aspects, the central suction port has dust larger than the dust sucked from the outer peripheral suction port.
