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.

The nozzle 22 held by the slave unit 20 is a hollow pipe that protrudes in the orthogonal direction from the side surface of one side or both sides of the main body 10 of the electric vacuum cleaner 10 and has a variable projection length. Although the pipe is in the shape of a pipe, the tip of the pipe has a vertically long oval shape that squeezes the pipe from the left and right, and the second suction port 21 is formed by opening the tip and the lower end. . And the front-end | tip part of the nozzle 22 is gripped by the subunit | mobile_unit 20, the base end part is connected to the suction pipe 18, The base end part has a telescopic structure, such as a nesting type and a bellows type.

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.

A rolling part 32 is fixed to the upper end of a pole 31 which is a hollow tube, and a pole grip part 311 having a U-shape and a substantially circular cross section is fixed to an intermediate part. Further, the upper end portion of the pole 31 is nested, and is urged so as to lightly press the ceiling surface.

The rolling part 32 includes a caster mounting plate 322 which is a rectangular plate directly fixed to the upper end portion of the pole 31 and four universal casters 321 fixed on the caster mounting plate 321 at equal intervals. Is pressed by the pole 31 and is brought into close contact with the ceiling surface, and is rotated following the traveling of the self-propelled electric vacuum cleaner 1.

Here, the usage method of the self-propelled electric vacuum cleaner 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.

An example of the procedure when the self-propelled vacuum cleaner 1 is used as a vacuum cleaner will be described with reference to FIG.
(1-1) When the suction switch of the remote-controlled transmitter is turned ON and the travel switch is also turned ON, the signal is transmitted to the receiver built in the vacuum cleaner main body 10 and the suction motor 15 is operated, and the first The drive motor 12 is operated, and the self-propelled vacuum cleaner 1 is self-propelled while sucking dust and dirt on the floor surface.
(1-2) By the operation of the suction motor 15, an air flow is generated in the suction pipe 18, and the air in the first suction port 11 → the dust collecting chamber 17 → the suction motor 15 → the exhaust port (not shown). A distribution channel 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.
(1-3) 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.
(1-4) When the remote control transmitter cordless handset 20 is turned on, the cordless handset 20 is detached from the main body 10 of the vacuum cleaner, and the power supply to the first drive motor 12 is stopped. Electric power is supplied to the drive motor 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 switch 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.
(1-5) When the dust collection chamber 17 is filled with dust or dirt, a dust outlet (not shown) communicating with the dust collection chamber 17 is opened and discarded.
When the self-propelled electric vacuum cleaner 1 travels, the pole 31 also moves and becomes a walking aid for an elderly person who holds 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 1 does not fall down during a walk, and a user's fall can also be prevented.

In addition, Example 1 is an Example which concerns on invention of Claim 3 which quotes only Claim 1, and is comprised about the structure about the self-propelled electric vacuum cleaner 1 with the vacuum cleaner main body 10 and the vacuum cleaner main body. A hollow nozzle 22 that protrudes in the orthogonal direction from one or both side surfaces of 10 and has a variable protruding length, and a pole 31 that is attached to the rear side of the vacuum cleaner body 10 and extends upward. In the embodiment according to the first aspect of the present invention, the nozzle 22 is configured according to the description in paragraph [0016]. Moreover, about the self-propelled vacuum cleaner 1, although the subunit | mobile_unit 20 is arrange | positioned only on one side, you may arrange | position on both sides.

Next, the self-propelled vacuum cleaner 2 according to the second embodiment will be described with reference to FIG. 3. The self-propelled vacuum cleaner 2 is an outrigger in addition to the slave unit 20 of the self-propelled vacuum cleaner 1. 25, only the outrigger 25 will be described.

The outriggers 25 are disposed on both side surfaces of the vacuum cleaner body 10 and are housed in the vacuum cleaner body 10 when not in use. The outrigger 25 is composed of a telescoping pipe, and is drawn out from the electric vacuum cleaner main body 10 and extends when in use. Further, an auxiliary wheel 26 is fixed in the vertical direction and the horizontal direction at the tip, and is rotated in the vertical direction and the horizontal direction. FIG. 3 shows a case where the auxiliary wheel 26 is fixed in the vertical direction and rotates, and the shaft support portion of the auxiliary wheel 26 rotates 90 ° in the direction of the arrow.

By using the outrigger 25, the self-propelled vacuum cleaner 2 is more stable when the auxiliary wheel 26 rotates in the vertical direction, and can be prevented from falling during use. When moving, it can prevent contact with obstacles such as walls.

Next, the self-propelled electric vacuum cleaner 3 according to the third embodiment will be described with reference to FIGS. 4 and 5. The self-propelled electric vacuum cleaner 3 mainly includes the electric vacuum cleaner main body 10 and the electric vacuum cleaner. It is comprised from the subunit | mobile_unit 20 accommodated in the subunit | mobile_unit accommodation space 19 of the machine main body 10, and the pole 31 attached to the back side, ie, back side, of the vacuum cleaner main body 10, and extended upwards, and is self-propelled Since the configuration of the vacuum cleaner main body 10, the slave unit 20, and the pole 31 in the electric vacuum cleaner 3 is substantially the same as that of the first embodiment and the difference is the rolling part 32, the rolling part 32 is mainly used here. Will be described.

The rolling part 32 includes a crawler belt 325 and a shaft joint 326 that connects the crawler belt 325 and the pole 31. The crawler belt 325 is composed of a crawler plate connected endlessly so as to surround a pair of moving wheels, and the crawler belt 325 itself is supplied with electric power from the rechargeable storage battery 16 and the ceiling surface according to the movement of the vacuum cleaner main body 10. 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.

Here, the traveling flow of the self-propelled electric vacuum cleaner 3 will be described with reference to FIG.
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.
In particular,
(2-1) Electric power is supplied to the first drive motor 12 and the rolling unit 32, and the main body of the self-propelled electric vacuum cleaner 3 and the rolling unit 32 travel.
(2-2) The rolling part 32 is delayed from the main body of the self-propelled electric vacuum cleaner 3, and the inclination of the pole 31 exceeds the predetermined range by the inclination sensor and becomes the “+” side (clockwise in FIG. 4). In this case, the power supply to the first drive motor 12 is stopped, and conversely, the main body of the self-propelled electric vacuum cleaner 3 is delayed from the rolling part 32 and the inclination of the pole 31 is on the “−” side (FIG. 4). Is counterclockwise), the power supply to the rolling part 32 is stopped and the inclination of the pole 31 is adjusted to fall within a predetermined range.
(2-3) If the inclination of the pole 31 by the inclination sensor is within a predetermined range, electric power is continuously supplied to the first drive motor 12 and the rolling unit 32.
The upper end portion of the pole 31 is nested, and is urged so as to lightly press the ceiling surface, so that the crawler belt 325 is always in contact with the ceiling surface.

With the above configuration, when the first traveling wheel 13 of the child device 20 rotates, the 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 body 10 itself and the traveling of the crawler belt 325 are synchronized, so that the self-propelled vacuum cleaner 3 travels integrally in appearance.

When the descending wall is suspended from the ceiling surface, the following process is performed.
(3-1) When the crawler belt 325 traveling on the ceiling surface hits the descending wall, the crawler belt 325 is lowered along the descending wall while being inclined with respect to the pole 31 by the action of the shaft coupling 326.
(3-2) 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 main body 10 moves horizontally in accordance with the movement of the electric vacuum cleaner main body 10. As a result, the pole 31 is inclined so that the lower part protrudes in the traveling direction.
(3-3) 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 body 10 Is stopped (see paragraph [0028] and FIG. 5). 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 3 can travel in the room and assist elderly people who hold the pole grip portion 311 of the pole 31. Can become a tool.

The structure of the electric vacuum cleaner main body 10, the slave unit 20, and the pole 31 is substantially the same as that of the first embodiment, and the difference is the rolling part 32. Therefore, here, the rolling mainly located at the upper part of the pole 31 is used. The unit 32 will be described.

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.
