  The interior of the vacuum cleaner main body 10 having a housing shape is opened at the front end (left side in FIG. 1) at the lower part across the entire width of the vacuum cleaner main body 10 (hanging from the front side to the back side in FIG. 1). The first suction port 11 is fixed. The first suction port 11 communicates with the suction pipe 18, and the dust collection chamber 17 and the suction motor 15 communicate with each other through the suction pipe 18, and the suction motor 15 is connected to the vacuum cleaner main body 10. It is connected to an exhaust port (not shown) that opens to the outside. That is, the air sucked by the first suction port 11 is exhausted from the exhaust port through the dust collection chamber 17 and the suction motor 15.

  A pair of left and right front wheels 14 are pivotally supported in front of both sides of the vacuum cleaner main body 10, and a pair of left and right first traveling wheels 13 are disposed on the rear side. Each has a first drive motor 12 attached thereto. And each of the 1st drive motor 12 drives independently, The rotation speed of the 1st driving | running | working wheel 13 can be varied, and the driving | running | working direction of the vacuum cleaner main body 10 can be changed now. Further, the side surface between the front wheel 14 of the electric vacuum cleaner body 10 and the first traveling wheel 13 is open to form a slave unit accommodation space 19. In addition, a rechargeable storage battery 16 is provided next to the dust collection chamber 17, and an electric cord (not shown) for connection to an external power supply is stored in the rechargeable storage battery 16, and an external power supply is provided as necessary. Can be connected to.

  Similarly to the electric vacuum cleaner main body 10, the slave unit 20 also has a housing shape and can be detachably accommodated in the slave unit accommodation space 19. The entire slave unit 20 is slightly lifted in the slave unit accommodation space 19. It is housed in the state. For this reason, when the subunit | mobile_unit 20 is accommodated, the 2nd driving | running | working wheel 24 of the subunit | mobile_unit 20 mentioned later does not become the obstruction | occlusion of the driving | running | working of the vacuum cleaner main body 10.

A second suction port 21 is formed. The distal end portion of the nozzle 22 is gripped by the slave unit 20, the proximal end portion of the proximal end portion communicates with the suction pipe 18, and the proximal end portion has a telescopic structure such as a telescopic type or a bellows type. . In addition, you may make it provide the nozzle which can protrude also in the orthogonal direction with respect to the driving | running | working direction of the subunit | mobile_unit 20, In this case, a larger area can be cleaned at once.

  Further, when the slave unit 20 is pulled out from the main body 10 of the vacuum cleaner, the power supply to the first drive motor 12 is stopped and the power of the second drive motor 23 is supplied. The machine 20 itself is slightly lowered so that the second traveling wheel 24 is landed on the floor.

Here, the usage method of the self-propelled vacuum cleaner 1 which concerns on Example 1 is demonstrated.
As described above, the self-propelled vacuum cleaner 1 is a cordless type vacuum cleaner with a built-in rechargeable storage battery. When not in use, an unillustrated electric cord is pulled out from the main body 10 of the vacuum cleaner and connected to an outlet. Can be charged.

The example of a procedure in the case of using the self-propelled vacuum cleaner 1 as a vacuum cleaner is as follows.
(1) When the suction button of the remote-controlled transmitter is turned on and the travel button is also turned on, the signal is transmitted to the receiver built in the main body 10 of the vacuum cleaner, and the suction motor 15 is operated, and the first drive motor 12 operates, and the self-propelled vacuum cleaner 1 is self-propelled while sucking dust and dirt on the floor.
(2) Due to the operation of the suction motor 15, an air flow is generated in the suction pipe 18, and the air flow path of the first suction port 11 → the dust collecting chamber 17 → the suction motor 15 → the exhaust port (not shown). Is formed. For this reason, the dust sucked together with the air from the first suction port 11 is sieved in the dust collecting chamber 17, and the remaining air is discharged out of the vacuum cleaner body 10 from the exhaust port.
(3) The direction of the self-propelled vacuum cleaner 1 is changed by changing the rotational speed of the first traveling wheel 13 of the main body 10 of the vacuum cleaner. That is, when bending to the right, a large amount of current flows through the first drive motor 12 attached to the first traveling wheel 13 on the right side according to a command from a remote-controlled transmitter to increase the rotational speed, and to the left In the case of bending to the left, a command from the remote control transmitter is operated so that a large amount of current flows through the first drive motor 12 attached to the left first traveling wheel 13 to increase the left rotation speed. Will be.
(4) When the button of the handset 20 of the remote-controlled transmitter is turned on, the handset 20 is detached from the main body 10 of the vacuum cleaner, the power supply to the first drive motor 12 is stopped, and the second drive motor Power is supplied to 23 and the suction motor 15 is operated. For this reason, an air flow is generated in the suction pipe 18, and an air flow path of the second suction port 21 → the dust collection chamber 17 → the suction motor 15 → the exhaust port (not shown) is formed. Thereby, the dust sucked together with the air from the second suction port 21 is sieved in the dust collecting chamber 17, and the remaining air is discharged out of the vacuum cleaner main body 10 from the exhaust port. Further, by turning on the forward / backward button of the slave unit travel of the remote-controlled transmitter, the slave unit 20 can perform forward travel and reverse travel while sucking dust and dirt. In this case, since the suction area expands in the horizontal direction, a large area can be cleaned in a short time.
(5) When the dust collection chamber 17 is filled with dust or dust, a dust outlet (not shown) communicating with the dust collection chamber 17 is opened and discarded.

  In addition, about the self-propelled vacuum cleaner 1, although the subunit | mobile_unit 20 is arrange | positioned only at one side, it is also possible to arrange | position on both sides. Furthermore, it is also possible to attach a hollow nozzle itself which can be moved in and out and whose projecting length is variable in place of the slave unit 20 to one side or both sides of the vacuum cleaner main body 10.

Is pressed by the pole 31 and is in close contact with the ceiling surface, and is rotated by the traveling of the self-propelled electric vacuum cleaner 2.

  When the self-propelled vacuum cleaner 2 travels according to the above configuration, the pole 31 also moves and becomes a walking aid for an elderly person who grips the pole grip portion 311 of the pole 31 to facilitate walking. And since the rolling part 32 presses a ceiling surface in a wide surface, the self-propelled vacuum cleaner 2 does not fall down during a walk, and a user's fall can also be prevented.

Next, the self-propelled electric vacuum cleaner 3 according to the third embodiment will be described with reference to FIG.
The self-propelled vacuum cleaner 3 mainly includes a vacuum cleaner body 10, a handset 20 accommodated in the handset accommodation space 19 of the vacuum cleaner body 10, and a rear side of the vacuum cleaner body 10, that is, a back side. A pole 31 is attached and extends upward. In addition, since the structure of the vacuum cleaner main body 10 and the subunit | mobile_unit 20 in Example 3 is the same as that of Example 1, and the pole 31 is substantially the same as Example 2, and the difference is the rolling part 32, here Then, the rolling part 32 located mainly on the upper part of the pole 31 is demonstrated.

  The rolling part 32 includes a rail 323 suspended from the ceiling and a suspended wheel 324 including a pair of wheels that travel while sandwiching the rail 323. The rail 323 has an inverted T-shaped cross section, and is arranged such that the wheels of the suspension type wheel 324 sandwich the rail 323. The suspended wheel 324 is fixed to the pole 31 via a flat connecting plate, and the suspended wheel 434 always presses the flange surface of the rail 433 by the telescopic pole 31.

When the self-propelled vacuum cleaner 3 travels with the above configuration, the pole 31 also moves and becomes an elderly walking aid that grips the pole grip portion 311 (see FIG. 2) of the pole 31 to facilitate walking. To do. And since the rolling part 32 clamps the rail 323 firmly, the self-propelled electric vacuum cleaner 2 does not fall down while walking, and the user can be prevented from falling.
In addition, it can replace with a rail and can use the rope stretched in the state which tension | tensile_strength applied to the ceiling surface vicinity.

Next, the self-propelled electric vacuum cleaner 4 according to the fourth embodiment will be described with reference to FIG.

Is supposed to travel. Further, the shaft coupling 326 pivotally supports the crawler belt 325 so as to allow the crawler belt 325 to freely tilt.

  An inclination sensor (not shown) is attached to the pole 31 to detect the inclination of the pole 31, and when the inclination exceeds a certain range, the power supply to the first drive motor 12 or the wheels of the crawler belt 325 is stopped. When the electric vacuum cleaner main body 10 or the crawler belt 325 stops traveling, the electric power is supplied again when the inclination of the pole 31 falls within a certain range. Further, since the upper end portion of the pole 31 is nested, and is biased so as to lightly press the ceiling surface, the crawler belt 325 is always in contact with the ceiling surface.

  When the first traveling wheel 13 of the child device 20 rotates by the above configuration, the electric vacuum cleaner main body 10 itself travels, while the driving wheel of the crawler belt 325 rotates and the crawler belt 435 also travels. If the ceiling surface is flat, the traveling of the vacuum cleaner main body 10 itself and the traveling of the crawler belt 325 are synchronized, so that the self-propelled vacuum cleaner 4 travels integrally in appearance.

When the descending wall is suspended from the ceiling surface, the following process is performed.
(1) When the crawler belt 325 traveling on the ceiling surface hits the descending wall, the crawler belt 325 descends along the descending wall while being inclined with respect to the pole 31 by the action of the shaft coupling 326.
(2) At this time, although the upper part of the pole 31 hardly moves horizontally, the lower part of the pole 31 fixed to the electric vacuum cleaner body 10 moves horizontally in accordance with the movement of the electric vacuum cleaner body 10. As a result, the pole 31 is inclined so that the lower part protrudes in the traveling direction.
(3) The inclination sensor attached to the pole 31 detects the inclination of the pole 31, and when the inclination exceeds a certain range, the power supply to the first drive motor 12 is stopped and the electric vacuum cleaner main body 10 travels. Stops. On the other hand, the crawler belt 325 travels as it is and descends along the descending wall, goes around the lower end of the descending wall, and ascends along the wall behind the descending wall. As a result, when the inclination of the pole 31 is gentle or reverse and the detection angle by the inclination sensor falls within a certain range, the power supply to the first drive motor 12 is resumed and the main body of the vacuum cleaner is resumed. 10 runs.
Thus, even if there is an obstacle protruding from the ceiling surface, the self-propelled vacuum cleaner 4 can travel indoors and assist elderly people who hold the pole grip portion 311 of the pole 31. Can become a tool.
