In addition, a lower suction port 38 connected to the lower path 29 in the accommodated state is formed in the lower front portion of the box body 33 in the left-right direction. In this state, an upper dust collection chamber S1 is formed above the tray 36 and a lower dust collection chamber S2 is formed below the tray 36 in a separated state in the dust collection box 7.

The lid 34 has a horizontally long exhaust tube 40 protruding from the rear surface thereof, an upper lid 39 provided with a pair of left and right lock plates 41, 41 on the front surface, a lower lid 42 fitted to the lower surface of the upper lid 39, an upper lid 39 and a lower The filter 43 is sandwiched between the lid 42 and the lock plate 41, 41 can be locked and released with respect to the box body 33 by sliding the lock plates 41, 41 to the left and right. On the upper side of the tray 36, an air passage is formed in which air that has entered the upper dust collection chamber S <b> 1 from the upper suction port 37 passes through the lid 34 through the filter 43 and is then discharged from the exhaust tube 40.
The fan unit 6 is accommodated in the main body 2 behind the rear wall 44 of the accommodating portion 27, and an intake port 46 provided on the upper front side of the casing 45 is connected to the exhaust tube 40 at an opening position provided on the rear wall 44. Communicate. A suction motor 47 having a suction fan 48 attached to the upper side of the rotating shaft is provided at the lower part of the casing 45, and air sucked from the intake port 46 by the rotation of the suction fan 48 is provided in the lower part of the casing 45. It is possible to discharge from the exhaust ports 49, 49. Outer exhaust ports 50, 50... Are formed on the rear surface of the upper housing 11 outside the inner exhaust port 49.

  Then, on the left and right sides of the fan unit 6 at the rear portion of the upper housing 11, mounting portions 51 and 51 for the batteries 3 and 3 are formed in a cutout shape. The mounting portion 51 is disposed symmetrically with respect to the center line in the front-rear direction of the main body portion 2. The battery 3 attached to the attachment part 51 is an 18V lithium ion battery used as a power source of the electric tool, and the attachment part 51 has the same structure as the attachment part provided in the electric tool. That is, at the innermost part of the mounting portion 51, a pair of guide rails (not shown) that fits from the outside to the rail provided in the joint portion of the battery 3 is formed upward, and a positive and negative terminal plate is provided between the guide rails. The terminal block is provided facing upward. Therefore, the battery 3 is inserted into the mounting portion 51 from above, so that the rail is fitted and coupled to the guide rail, and the terminal block is electrically connected to the connection terminal provided at the coupling portion of the battery. The Thus, since the battery 3 for electric tools is used as a power supply, it is not necessary to prepare a different battery for every model, versatility is acquired, and cost and management effort are not required.

Here, the mounting portion 51 is formed so as to be inclined from the front-rear direction so that the innermost surface to which the battery 3 is coupled is along the tangential direction of the main body portion 2, and when the batteries 3 and 3 are mounted, the main body portion 2. It is set to face the center. Since the battery 3 is tilted and attached in a radial manner in this way, the battery 3 can be disposed on the outermost side along the outer shape of the main body 2, and no useless space is generated outside the battery 3.
Furthermore, since the battery 3 is arranged in a balanced manner on the left and right with respect to the center line in the front-rear direction of the main body 2, even if there are two batteries 3, there is no bias in the center of gravity. In particular, since the casters 8 and 8 are positioned directly below the batteries 3 and 3 to which the casters 8 and 8 are attached, the running stability is good, and the straight running performance is not deteriorated even if one of the batteries 3 is not attached.

On the other hand, in FIG. 4, 52 is a controller provided between the left and right side brush motors 21, 21, and this controller 52 is supported by a boss 53 erected on the lower housing 10. And a control circuit board 55 fixed on the support base 54.
In addition, the upper housing 11 behind the lid 31 is provided with an operation unit 56 including operation buttons such as a power button 57, a battery 3 remaining amount display unit 58, and an operation mode selection button 59. Below the operation unit 56, a switch board 60 including a switch that is turned ON / OFF by operating each operation button is provided.
Further, a display lens 61 is provided in the upper housing 11 in front of the lid 31, and an LED substrate 62 having LEDs that emit light below the lens 61 is provided below the display lens 61.

  A flat surface 63 as a support surface orthogonal to the front-rear direction is formed on the rear surface of the upper housing 11 at the rear portion of the main body portion 2. The flat surface 63 is formed so as to be chamfered from the rear of the operation portion 56 to the left and right mounting portions 51, 51, but the battery 3 mounted on the mounting portion 51 protrudes rearward from the flat surface 63. It is supposed not to. The outer exhaust port 50 is formed on the flat surface 63, but here, a concave portion 64 is formed in the flat surface 63, and the outer exhaust port 50 is disposed in the concave portion 64, so that it is more than the flat surface 63. Open on the back side (front side).

  In the dust collecting robot 1 configured as described above, the brush 19 of the main brush 17 and the brush 24 of the side brush 22 are respectively connected to the floor when the battery 3 is mounted on the mounting portion 51 and set on the floor surface. Contact the surface. Here, when the operation mode is selected by pressing the power button 57 of the operation unit 56, the wheel motors 4 and 4 are driven to rotate the wheels 5 and 5 and travel on the floor according to the set program. At the same time, the main brush motor 20 and the side brush motor 21 are driven to rotate the main brush 17 and the side brush 22, respectively, and the suction motor 47 is also driven to rotate the suction fan 48. Accordingly, the dust on the floor surface is scraped up by the rotating main brush 17 and sucked from the suction port 15 by the suction force of the suction fan 48 and sent to the dust collection box 7 at the rear. At the same time, the side brushes 22 and 22 also bring outside dust to the main brush 17 side.

  At this time, large dust is stored in the lower dust collection chamber S <b> 2 in the box body 33 from the lower suction port 38 of the dust collection box 7 through the lower path 29. Since the lower suction port 38 is higher than the bottom surface of the box body 33 serving as the bottom surface of the lower dust collection chamber S2, dust stored in the lower dust collection chamber S2 is less likely to flow backward from the lower suction port 38. On the other hand, the small dust is discharged from the exhaust tube 40 to the fan unit 6 through the filter 43 through the upper suction port 37 through the upper suction port 37 through the upper suction port 37 through the air sucked from the suction port 15. As a result, it is captured by the filter 43 and stored in the upper dust collection chamber S1.

  On the other hand, the batteries 3 and 3 are used as power sources one by one in order, and the remaining capacity of the battery 3 is displayed on a remaining amount display unit 58 provided in the operation unit 56. Therefore, when the remaining capacity of one battery 3 runs out first, the battery 3 can be removed from the mounting portion 51 and charged by an external charger. In this case, it can be driven only by the other battery 3, but since the casters 8 and 8 are provided symmetrically as described above, even if the center of gravity of the main body 2 is biased by one battery 3, Stable traveling is possible by the left and right casters 8 and 8.

When the dust collecting robot 1 is stored after the cleaning is completed, the handle 32 is pulled out to lift the dust collecting robot 1 to the storage position, and the dust collecting robot 1 is raised with the flat surface 63 facing down. Let Then, as shown in FIG. 5, the flat surface 63 is placed on the floor surface L and the dust collecting robot 1 is self-supporting in a vertical posture, so that it can be stored in a stable state in a posture parallel to a wall or the like. In particular, since the batteries 3 and 3 are self-supporting in this case, the center of gravity is located on the lower side in a self-supporting state, which is a more stable state.
Further, in the self-supporting state, the outer exhaust port 50 is opened by the recessed portion 64 on the back side of the flat surface 63 and does not directly contact the floor surface L. Therefore, even if there is dust or the like on the floor surface L, the outer exhaust port 50 It becomes difficult to adhere.

Furthermore, when the dust collection robot 1 is in a self-supporting state, the dust collection box 7 in the main body 2 is in a vertically placed posture with the upper and lower suction ports 37 and 38 facing upward, so that dust in the dust collection box 7 may spill out. There is no.
And in the self-supporting state, the sensor cover 12 on the upper side is lowered by its own weight, and becomes a position for turning on the collision sensor. Therefore, when the controller 52 confirms that the ON signal of the collision sensor has been continuously detected for a predetermined time or longer when the power button 57 is forgotten to be turned off and stored in a self-supporting manner, a function of automatically turning off the power can be provided. it can.

Thus, according to the dust collection robot 1 of the said form, the main-body part 2 was provided with the support surface (flat surface 63) which can stand in the vertical orientation, and can be stored vertically in a stable state.
In particular, here, since the support surface is a flat surface 63 formed by chamfering on the peripheral surface of the main body 2, the support surface is not protruded from the main body 2, and the dust collecting robot 1 is narrow. There is no risk of interfering with surrounding obstacles when changing directions at a place.
Moreover, since the flat surface 63 is provided on the battery 3 mounting side, the battery 3 is placed vertically and the center of gravity is on the lower side, so that more stable independence is possible.
Further, since the concave portion 64 is formed in the flat surface 63 and the outer exhaust port 50 of the suction fan 48 is formed in the concave portion 64, dust or the like on the floor surface hardly adheres to the outer exhaust port 50 when it is made to stand by itself. Therefore, the risk of a decrease in exhaust efficiency can be reduced.

  In the above embodiment, the flat surface is provided at the rear portion of the main body portion. However, the flat surface may be provided at the front portion or the side portion so as to be able to stand on its own. Further, the support surface is not limited to a flat surface, and it is possible to prevent slipping as an uneven surface having protrusions and grooves.

However, the vertical storage of the dust collecting robot is not limited to using the support surface, and may be provided with a leg portion so as to be able to stand on its own. Modification examples provided with the legs are shown in FIGS.
In the dust collecting robot 1A, a pair of leg portions 65, 65 are provided on the front surface of the sensor cover 12 so as to be able to be taken in and out. The leg portion 65 has a plate shape that curves in accordance with a storage recess 66 that is recessed along the outer peripheral surface of the sensor cover 12, and the left and right outer ends are rotatably connected by a shaft (not shown) in the vertical direction. . Then, as shown in FIG. 6, the drawer position is projected forward from the sensor cover 12 so as to abut against the outer step portion 67 of the storage recess 66, and the rotation is restricted, and as shown in FIG. It is possible to put it in and out of the storage position where it is folded in and not protruded from the sensor cover 12.

  Therefore, when cleaning, if the leg portions 65 and 65 are folded to the retracted position as shown in FIGS. 7 and 8, the leg portions 65 and 65 can be cleaned without getting in the way. Then, when storing the dust collecting robot 1A, as shown in FIG. 9, if the legs 65 and 65 are pulled out to the pull-out position and the sensor cover 12 side is faced down, the sensor cover 12 Since the dust collecting robot 1A is self-supported by being supported by the leg portions 65 and 65 on both sides of the center portion in contact with the floor surface L, it can be stored in a stable state in a posture parallel to a wall or the like. Also in this case, since the sensor cover 12 on the floor side is pushed into a position where the collision sensor is turned on due to the weight of the main body 2, the controller 52 causes the collision sensor ON signal to exceed a predetermined time when the power supply is forgotten to be turned off. When it is confirmed that the power source is continuously detected, a function of automatically turning off the power can be provided.

Therefore, also in the dust collecting robot 1A of this modified example, the leg portions 65, 65 are provided so as to be able to be inserted into and removed from the main body portion 2 between the pull-out position and the storage position, so that they can be stored vertically in a stable state. Further, by storing in the storage position at the time of cleaning, it does not interfere with traveling.
Note that the shape of the leg portion is not limited to the above example, and the leg portion can be provided on the rear portion or the side portion of the main body portion, or can be provided so as to be foldable on a flat surface or a bottom surface. It is also conceivable to provide legs so that they can be taken in and out in the radial direction of the main body instead of being folded.

On the other hand, although the dust collecting robot is made to stand on its own by the support surface and legs in the above-mentioned forms and modifications, for example, as shown in FIG. A pair of chamfered portions 68 and 68 are provided, and one of the chamfered portions 68 is brought into contact with the floor surface L and the other chamfered portion 68 is brought into contact with the wall surface W as a leaned surface, thereby maintaining the leaning posture. It can also be placed vertically in an inclined manner.
If the chamfered portions 68 and 68 are provided in this way, the standing posture of the dust collecting robot 1B is stabilized and can be stored vertically without rolling or sliding along the wall surface W. The chamfered portion 68 supports the supporting portion. Can also be formed easily. In this case, an anti-slip member such as rubber may be adhered to the chamfered portion 68, or unevenness or grooves may be provided to increase the friction with the floor surface. The chamfered portions may be provided on the left and right lower surfaces of the main body portion, or may be provided only on one of them instead of a pair.

In addition, in the dust collecting robot, it is not necessary to provide both the main brush and the side brush as the dust collecting function, and the side brush may be omitted and only the main brush may be used. Further, the dust collection path is not limited to the case where the dust collection path is branched up and down, but may be collected in the dust collection box through a single path. Therefore, the form of the dust collection box can be appropriately adopted such as one without a tray, and there is no problem even if there is no dust collection box and dust is stored directly in the main body. The main body is not limited to a circular shape in plan view. Moreover, a self-supporting structure can be adopted even if it is a type that wipes and cleans the floor instead of collecting dust or a type that performs dust collection and wiping and cleaning in parallel.
Furthermore, the number of batteries is not limited to two, and three or more batteries can be used if they can be arranged in a balanced manner on the left and right. The present invention is also applicable to a type in which the traveling direction is reversed, that is, a self-propelled dust collecting robot in which the battery and the caster are in the front part of the main body part and the suction port is in the rear part of the main body part. is there.
