DESCRIPTION OF THE PREFERRED EMBODIMENTS A mode for carrying out the invention will be described with reference to the accompanying drawings. In each figure, the same or corresponding parts are given the same reference numerals. Duplicate explanations of the relevant parts will be simplified or omitted as appropriate. Further, the present invention is not limited to the following embodiments, and various modifications can be made without departing from the spirit of the present invention. In the following description, air mixed with dust will be referred to as "dust-containing air." Air from which dust has been removed is called "clean air." Further, in some of the figures, attachments are omitted (not shown).

Embodiment 1.
FIG. 1 is a perspective view of a vacuum cleaner system according to a first embodiment. FIG. 2 is a top view of the vacuum cleaner system in the first embodiment. FIG. 3 is a side view of the vacuum cleaner system in the first embodiment.

As shown in FIG. 1, the vacuum cleaner system includes a vacuum cleaner 1 and a support device 2. The top and bottom, front and back, left and right directions of the cleaning system shall be as shown in Figures 1 and 2.

The vacuum cleaner 1 is removed from the support device 2 when cleaning is performed. After cleaning is completed, the vacuum cleaner 1 is attached to the support device 2 while maintaining the direction of movement. At this time, the front part of the vacuum cleaner 1 is held by the support device 2. As a result, the vacuum cleaner 1 is arranged with the rear part as the design surface. The vacuum cleaner 1 and the vacuum cleaner system have symmetry in the left-right direction in appearance.

For example, the vacuum cleaner 1 includes a main body 3, a pipe body 4, a suction tool 5, and an attachment 24.

For example, the tube body 4 is formed into a rod shape. The tube 4 extends downward from the main body 3. The upper end of the tube body 4 is detachably attached to the rear part of the main body 3. A rear portion and a middle portion in the width direction of the suction tool 5 is provided to be detachably attached to the lower end portion of the tube body 4.

The attachments 24 are, for example, a suction attachment and a blower attachment. The suction attachment is, for example, a bristle brush 25. The blower attachment is, for example, a blower nozzle 26. Note that contents common to the suction attachment and the blower attachment will be collectively described as the attachment 24.

The attachment 24 is detachably provided to the support device 2 . The upper end of the bristle brush 25 is detachably attached to the rear of the main body 3. The upper end of the blower nozzle 26 is detachably attached to an exhaust port 29 of the main body 3, which will be described later.

For example, the support device 2 is placed on the floor of a living room. For example, the support device 2 is a charging stand that charges the vacuum cleaner 1. A part of the support body 7 is formed of a metal member. For example, a part of the support device 2 is formed of a steel plate. The support body 7 is heavier than the vacuum cleaner 1. For example, the support device 2 includes a base 6, a support 7, and a holder 8.

The base body 6 is arranged at the lowest position in the support device 2 . For example, the base 6 is placed on the floor near the wall of the living room. For example, the support body 7 is columnar. For example, the lower end of the support 7 is fixed to the base 6. The holding body 8 is arranged above the base body 6. For example, the holder 8 is placed directly above the base 6. The holder 8 is supported by the support 7. The holder 8 is fixed to the upper end of the support 7.

The centers of gravity of the base body 6, support body 7, and holder 8 are set at a low position so that the support device 2 is unlikely to fall when the vacuum cleaner 1 is attached or detached. Specifically, the base body 6 is heavier than the support body 7. The base body 6 is heavier than the holder 8. The base body 6 may be heavier than the combined weight of the support body 7 and the holding body 8. In other words, the mass of the base 6 is greater than the combined mass of the support 7 and the holder 8. This lowers the center of gravity, making it difficult for the support device 2 and the vacuum cleaner system to fall over.

When the vacuum cleaner 1 is attached to the support device 2, at least one of the main body 3 and the tube body 4 is held by the holder 8. The suction tool 5 is supported by the base body 6 of the support device 2 . At this time, the rear end of the suction tool 5 is arranged on the rear side of the tube body 4 and the main body 3.

When the vacuum cleaner 1 is removed from the support device 2 as a stick-type vacuum cleaner 1, the user moves the main body 3 in the direction A without lifting the main body 3 upward, as shown in FIG.

Note that the user may rotate the main body 3 in the direction B without lifting the main body 3 upward. Immediately after the main body 3 rotates in the B direction, it moves in the A direction. As a result, the tube body 4 becomes oblique with respect to the surface to be cleaned. Therefore, the vacuum cleaner 1 quickly shifts to the cleaning mode.

When the vacuum cleaner 1 is removed from the support device 2 as a hand-held vacuum cleaner 1, the user moves the main body 3 in the C direction. At this time, the tube body 4 is pulled by the main body 3 and moves in the C direction. Therefore, even if the main body 3 moves in the C direction, the tube body 4 remains held by the holder 8. At this time, the tube body 4 and the suction tool 5 do not come off from the support device 2.

Note that when the tube body 4 is not supported by the support device 2, the vacuum cleaner 1 can be attached to and detached from the support device 2 as a hand-held vacuum cleaner. For example, the user attaches and detaches the main body 3 by moving it laterally with respect to the support device 2. For example, the user attaches and detaches the main body 3 by moving it vertically relative to the support device 2.

Further, when the tube 4 is supported by the support device 2, the user moves the main body 3 from above the tube 4. As a result, the main body 3 is supported by the support device 2 while being connected to the tube body 4.

When the vacuum cleaner 1 is supported by the support device 2, a part of the main body 3 is placed directly above the suction tool 5. Therefore, the vacuum cleaner 1 and the support device 2 can be installed in a narrow space.

Next, a first usage example of the vacuum cleaner 1 will be described using FIG. 4. FIG. 4 is a perspective view showing a first usage example of the vacuum cleaner 1 in the first embodiment. As shown in FIG. 4, the main body 3 includes an outer shell 9, a handle 10, and a dust collection section 11.

The outer shell part 9 becomes a part of the design surface of the vacuum cleaner 1. As shown in FIGS. 3 and 4, the handle 10 defines the front-to-back direction of the vacuum cleaner system. The upper end of the handle 10 is provided above the outer shell 9. The dust collecting section 11 is formed in a cylindrical shape as a whole. The dust collecting section 11 is provided below the outer shell section 9.

When the vacuum cleaner 1 is used as a stick-type vacuum cleaner, a user holds the middle part of the handle 10. For example, the user cleans the floor surface with the longitudinal direction of the pipe body 4 being in an oblique direction. At this time, the tube body 4 is arranged below the main body 3.

Next, a second usage example of the vacuum cleaner 1 will be described using FIG. 5. FIG. 5 is a side view showing a second usage example of the vacuum cleaner 1 in the first embodiment. As shown in FIG. 5, the user cleans with the suction tool 5, which is not shown in FIG. 5, removed. For example, the user cleans a high place with the longitudinal direction of the pipe body 4 diagonally upward.

Next, a third usage example of the vacuum cleaner 1 will be described using FIGS. 6, 7, and 8. FIG. 6 is a side view of the main body 3 in the first embodiment. 7 and 8 are side views showing the main body 3 being attached and detached from the support device 2 in the first embodiment. When the main body 3 is attached and detached from the tube body 4 as shown in FIGS. 7 and 8, the vacuum cleaner 1 is used as a hand-held vacuum cleaner, as shown in FIG. The user cleans the surface to be cleaned with the pipe body 4 and suction tool 5 removed. At this time, the user holds the front end of the handle 10.

Next, a procedure for supporting the vacuum cleaner 1 on the support device 2 will be explained using FIG. 9. FIG. 9 is a side view showing a state in which the suction tool 5 according to the first embodiment is arranged at a specific position. Note that the attachment 24 is omitted (not shown) in FIG. 9 . For example, the suction tool 5 is loosely fitted to the base 6 and placed at a specific position.

The user tilts the main body 3 as shown in FIG. 4, holds the handle 10, and moves the suction tool 5 back and forth. At this time, the vacuum cleaner 1 is arranged diagonally so that the suction tool 5 is located in front of the main body 3. After cleaning, the user moves the vacuum cleaner 1 forward in the cleaning posture and places the suction tool 5 at a specific position on the support device 2. At this time, the suction tool 5 does not perform any special operation.

As shown in FIG. 9, immediately after the suction tool 5 is placed at a specific position, the main body 3 is placed behind the suction tool 5. The user moves the main body 3 and the tube body 4 in the E direction with the suction tool 5 placed at a specific position. The motion in the E direction is performed as a series of motions that move the cleaner 1 forward. The movement in the E direction is a movement in which the user holds the handle 10 and moves the suction tool 5 in an arc around the rotation axis. Therefore, the vacuum cleaner 1 is supported by the support device 2 without being lifted.

Next, a modification of the vacuum cleaner system will be described using FIGS. 10 to 13. FIG. 10 is a side view of the tube body 4 and the suction tool 5 supported by the support device 2 in the first embodiment. FIG. 11 is a side view of the main body 3 and the tubular body 4 supported by the support device 2 in the first embodiment. FIG. 12 is a side view of the tubular body 4 supported by the support device 2 in the first embodiment. FIG. 13 is a side view of the main body 3 supported by the support device 2 in the first embodiment. Note that the attachment 24 is omitted (not shown) in FIGS. 10 to 13.

As shown in FIG. 10, the tube 4 is held by the holder 8 in a state where the tube 4 and the suction tool 5 are connected. As shown in FIG. 11, the tube 4 is held by the holder 8 in a state where the main body 3 and the tube 4 are connected. As shown in FIG. 12, the tube body 4 is held by the holder 8 without the main body 3 and the suction tool 5. As shown in FIG. 13, the main body 3 is held by the holder 8 without the tube 4 and suction tool 5.

Next, the outer shell portion 9 and the handle 10 will be explained using FIGS. 14 and 15. FIG. 14 is a longitudinal cross-sectional view of the vacuum cleaner 1 in the first embodiment. FIG. 15 is a longitudinal sectional view of the main body 3 in the first embodiment. As shown in FIGS. 14 and 15, the outer shell part 9 includes a case part 12, a battery part 13, a connecting pipe part 14, and an exhaust part 15.

The case portion 12 is formed into a cylindrical shape as a whole. The case section 12 houses an electric blower 16 and a control section 17. Electric blower 16 is provided above dust collecting section 11 . The electric blower 16 is provided to take in and exhaust air. The control unit 17 is provided directly above the electric blower 16. For example, the control unit 17 controls the operation of the electric blower 16. The case portion 12 includes a convex portion 18 . The convex portion 18 is provided at the front of the case portion 12.

The battery part 13 is housed in the rear part of the outer shell part 9 below the rear end part of the handle 10. Battery section 13 is adjacent to case section 12 . The battery section 13 includes a plurality of secondary batteries. The voltages of the plurality of secondary batteries are controlled by the control unit 17.

The connecting pipe section 14 and the exhaust section 15 have, for example, a main body side connection port 27. The attachment 24 can be detachably connected to the main body side connection port 27. The main body side connection port 27 may be provided only in the connection pipe portion 14. As will be described later, the main body side connection port 27 provided in the connecting pipe portion 14 is the suction port 28, and the main body side connection port 27 provided in the exhaust portion 15 is the exhaust port 29.

The connecting pipe section 14 is arranged along the dust collecting section 11 . The front side of the connecting pipe section 14 is adjacent to the dust collecting section 11 . The connecting tube section 14 is arranged on an extension of the battery section 13. The connecting tube portion 14 is a hollow tubular member to which the tube body 4 is detachably connected. The connecting pipe portion 14 has a suction port 28 for sucking in dust. The suction port 28 is one of the main body side connection ports 27. The suction port 28 is an opening formed at one end of the connecting pipe section 14 . The tube body 4 and the bristle brush 25 are removably inserted into the suction port 28 . An intake air passage is formed inside the connecting pipe section 14 to guide the airflow of dust-containing air that has passed through the suction port 28 to the dust collecting section 11 .

The connecting tube section 14 includes a fitting section 19 . The fitting portion 19 is formed in a triangular shape when viewed from the side. The fitting portion 19 protrudes to the outside of the connecting tube portion 14 as it goes upward.

An exhaust air passage is formed inside the main body 3. The exhaust air path is an air path through which air that has passed through the dust collection section 11 and the electric blower 16 is exhausted to the outside of the main body 3.

In this embodiment, a plurality of exhaust sections 15 are provided. However, the number of exhaust parts 15 may be one. This embodiment includes a first exhaust section 15a and a second exhaust section 15b.

The second exhaust part 15b is formed in the case part 12 at a position where the battery part 13 is accommodated. In this configuration example, the second exhaust portions 15b are provided on both sides of the case portion 12, respectively. That is, the second exhaust part 15b is arranged on the side surface of the main body 3.

The first exhaust part 15a is formed at a different position from the second exhaust part 15b. The first exhaust part 15a is formed at the front end and lower end of the handle 10. An exhaust port 29 is provided in the first exhaust section 15a. The exhaust port 29 is an opening through which air that has passed through the electric blower 16 is discharged to the outside of the main body 3. The exhaust port 29 opens in the same direction as the suction port 28.

The dust collection unit 11 is for collecting dust in the dust-containing air sucked into the main body 3 by suction air generated by the electric blower 16. The dust collecting section 11 is detachably attached to the main body 3. The overall shape of the dust collecting section 11 has a cylindrical appearance. The dust collection section 11 according to this embodiment includes a cyclone section 22 and a filter section 23. The cyclone section 22 is a cyclone separation device. The cyclone section 22 separates dust from the dust-containing air by swirling the dust-containing air therein using the air flow generated by the electric blower 16. The filter section 23 is for filtering out fine dust that could not be separated by the cyclone section 22 from the air flow.

The handle 10 is provided so that the main body 3 is visibly disposed when viewed from above in a state in which the main body 3 is supported by a support device 2 (not shown) in FIGS. 14 and 15. The handle 10 is formed across the main body 3 in the front-rear direction. For example, the handle 10 is formed from the upper end to the front. For example, the handle 10 is formed from the upper end to the rear. For example, the handle 10 is formed from the upper end to the front and back. For example, the handle 10 is formed at a lower position forward than the upper end. For example, the handle 10 is formed at a lower position behind the upper end. For example, the handle 10 is formed to extend back and forth from the center of the main body 3 in the front and back direction.

For example, the handle 10 is formed continuously from the front end to the rear end of the outer shell 9. For example, the front end and rear end of the handle 10 are provided in parallel. For example, the middle portion of the handle 10 is curved and connected to the front and rear ends of the handle 10 above the case portion 12. For example, the middle portion of the handle 10 is formed to be convex upward. For example, the rear end portion of the handle 10 is provided on the extension line of the tube body 4 on the rear side of the case portion 12 rather than the rear portion of the case portion 12. For example, the front end portion of the handle 10 is provided closer to the front side of the case portion 12 than the front portion of the case portion 12 . For example, the front end of the handle 10 is connected to the protrusion 18 of the case part 12.

Preferably, the handle 10 is located at the top of the body 3. Preferably, a space 20 is formed between the handle 10 and the case portion 12 in a side view. Preferably, the space 20 is formed directly below the upper end of the handle 10. The space 20 is used when the user holds the handle 10 from above, and the user may hold the handle 10 with a hand or finger inserted into the space 20.

The handle 10 includes an operating section 21. The operating section 21 is provided at the front of the handle 10. For example, the operation unit 21 includes a plurality of operation switches.

Although not shown, the main body 3 includes a left main body 3 side charging terminal portion 39L and a right main body 3 side charging terminal portion 39R. For example, the left main body 3 side charging terminal portion 39L and the right main body 3 side charging terminal portion 39R are provided at the front portion of the connecting tube portion 14. For example, the left main body 3 side charging terminal section 39L and the right main body 3 side charging terminal section 39R are provided below the dust collecting section 11.

The user operates the operating section 21 with the hand holding the handle 10. The control unit 17 uses power from the battery unit 13 to control the operation of the electric blower 16 based on the content of the operation on the operation unit 21 .

When the electric blower 16 operates, suction air is generated. The dust-containing air is sucked in from the suction tool 5 by the suction wind. Thereafter, the dust-containing air passes through the inside of the tube body 4. Thereafter, the dust-containing air passes through the inside of the connecting pipe section 14. Thereafter, the dust-containing air flows into the dust collecting section 11. At this time, the dust in the dust-containing air is collected in the dust collecting section 11. As a result, clean air is produced. The clean air flows out from the dust collecting section 11. Thereafter, the clean air passes through the electric blower 16. Thereafter, the clean air is discharged to the outside of the main body 3 from the exhaust section.

Next, the tubular body 4 will be explained using FIGS. 16 to 19. FIG. 16 is a perspective view of the tube body 4 in the first embodiment. FIG. 17 is a side view of the tube body 4 in the first embodiment. FIG. 18 is a longitudinal cross-sectional view of the tube body 4 in the first embodiment. FIG. 19 is a sectional view taken along line HH in FIG. 17.

As shown in FIG. 16, the tube body 4 includes a pipe portion 36, a cover pipe 37, a latch portion 38, a terminal portion 39, and a lead wire (not shown). The pipe portion 36 is a main member of the tube body 4. The upper end of the pipe section 36 is connected to the connecting tube section 14 inside the connecting tube section 14, which is not shown in FIG.

The pipe section 36 includes a pipe 40 and a fitting section 41. Pipe 40 is the main part of pipe section 36. The pipe 40 is formed into a cylindrical shape. The inside of the pipe 40 becomes an air path. The interior space of the pipe 40 has a longitudinal axis. The longitudinal axis has a linear shape. The fitting part 41 is arranged at the front and lower part of the pipe part 36. The fitting part 41 is provided so as to be able to fit into the suction tool 5, which is not shown in FIG.

The cover pipe 37 is coupled to the rear part of the pipe section 36. The cover pipe 37 has a cylindrical outer shape. In a state where the cover pipe 37 is coupled to the pipe portion 36, the combined outer shape of the pipe portion 36 and the cover pipe 37 is a straight rod shape.

The latch part 38 is arranged at the front and upper part of the tube body 4. The latch portion 38 is provided outside the pipe portion 36. For example, the latch section 38 is fixed to the pipe section 36 via the cover. For example, the latch portion 38 is directly fixed to the pipe portion 36. A central portion of the latch portion 38 is supported by the pipe portion 36. The latch portion 38 is provided so as to be able to fit into the main body 3, which is not shown in FIG. Specifically, the latch portion 38 is provided so as to maintain the connection between the lower end portion of the connecting tube portion 14 and the upper end portion of the tube body 4. The latch portion 38 includes a latch 42a and a cover latch 42b.

As shown in FIG. 18, the latch 42a includes a button portion 43a, a latch tip portion 43b, and a spring 43c. The latch 42a is displaced like a seesaw. For example, the latch 42a is displaced from the first position to the second position. For example, latch 42a is displaced from the second position to the first position. The first position is a position where the connection between the main body 3 and the upper end of the pipe portion 36, which is not shown in FIG. 18, is maintained. The second position is a position where the connection between the main body 3 and the upper end of the pipe portion 36 is released.

The latch 42a receives a force from the spring 43c so that the button part 43a moves away from the end of the pipe part 36. Therefore, if no external force other than the force from the spring 43c acts on the latch 42a, the latch 42a is placed in the first position.

When the button portion 43a is pushed closer to the pipe portion 36, the latch 42a is displaced from the first position to the second position. When the latch tip 43b contacts the fitting part 19 of the main body 3, the latch 42a changes from the first position.

Cover latch 42b covers latch tip 43b. For example, cover latch 42b is angled. For example, the cover latch 42b has a rounded shape. For example, the width of the cover latch 42b becomes narrower as the distance from the pipe portion 36 increases. The cover latch 42b serves as a guide when the tube body 4 is held by the holder 8.

When the tube body 4 and the fitting part 19 of the connecting tube part 14 move in the direction of separation with the latch 42a disposed at the second position, the latch tip part 43b engages with the fitting part 19 of the connecting tube part 14. is released from the mating. When the latch 42a is placed in the first position, the latch tip 43b fits into the fitting part 19 of the connecting tube part 14. At this time, the convex portion 18 of the fitting portion 19 of the connecting tube portion 14 prevents the pipe portion 36 from coming off from the connecting tube portion 14. Furthermore, when the latch tip 43b separates from the fitting part 19 of the connecting tube part 14, the latch 42a returns to the first position by the force from the spring 43c.

When the tube body 4 is inserted into the main body 3, the latch tip portion 43b contacts the fitting portion 19 of the connecting tube portion 14. When the tube 4 further moves toward the main body 3 from this state, the latch 42a changes from the first position. When the tube 4 further moves toward the main body 3 from this state, the main body 3 and the tube 4 are connected. At this time, the latch 42a returns to the first position. In this way, the connection between the main body 3 and the tube body 4 is performed without requiring any operation of the button portion 43a.

As shown in FIG. 19, the pipe portion 36 includes a left recess 44a and a right recess 44b. For example, the left recess 44a and the right recess 44b are provided at the front of the pipe 40. For example, the left recess 44a and the right recess 44b are provided behind the latch portion 38. For example, the left recess 44a and the right recess 44b are vertically long depressions.

For example, the left recess 44a is formed on the surface of the pipe portion 36 that faces leftward. The right recess 44b is formed on the right-facing surface of the pipe portion 36. On the other hand, the latch portion 38 is provided on the front surface of the pipe portion 36 . When the tube body 4 is viewed from above, the latch portion 38 is disposed between the left side recess 44a and the right side recess 44b.

The left recess 44a and the right recess 44b are arranged at the same height. For example, the left recess 44a and the right recess 44b are arranged at the same height as the latch 42a and the cover latch 42b. The minimum width of the left recess 44a and the minimum width of the right recess 44b are smaller than the maximum width of the cover latch 42b.

As shown in FIG. 17, the tubular body 4 includes a first left regulating section 45a, a first right regulating section 45b, a second left regulating section 46a, and a second right regulating section 46b. Note that the first left regulating section 45a and the second left regulating section 46a are arranged on the back side in FIG. 17. For this reason, in FIG. 17, the first left regulating section 45a and the second left regulating section 46a are not illustrated.

For example, the first left regulating section 45a, the first right regulating section 45b, the second left regulating section 46a, and the second right regulating section 46b are provided near the upper end of the pipe section 36. For example, the first left regulating section 45a, the first right regulating section 45b, the second left regulating section 46a, and the second right regulating section 46b are provided near the latch section 38.

The first left regulating portion 45a is arranged at the upper end of the left recess 44a. The first right regulating portion 45b is arranged at the upper end of the right recessed portion 44b. The first left regulating portion 45a and the first right regulating portion 45b are arranged at the same height. Note that the left recess 44a is arranged on the back side in FIG. 17. Therefore, in FIG. 17, the left recess 44a is not illustrated.

The second left regulating portion 46a is arranged at the lower end of the left recess 44a. The second right regulating portion 46b is arranged at the lower end of the right recessed portion 44b. The second left regulating portion 46a and the second right regulating portion 46b are arranged at the same height.

The terminal portion 39 is connected to a lead wire not shown in FIG. 17 . A portion of the terminal portion 39 and the lead wire are arranged between the pipe portion 36 and the cover pipe 37.

Next, a state in which the attachment 24 is supported by the support device 2 will be described using FIGS. 20 to 26. FIG. 20 is a perspective view of the attachment 24 attached to the support device 2 in the first embodiment. FIG. 21 is a main part of a rear view of the support device 2 according to the first embodiment with the attachment 24 attached. FIG. 22 is a side view of the main body 3 connected to the attachment 24 (bristle brush 25) attached to the support device 2 in the first embodiment. FIG. 23 is a side view of the main body 3 connected to the attachment 24 (blower nozzle 25) attached to the support device 2 in the first embodiment. FIG. 24 is a top view of the support device 2 according to the first embodiment with the attachment 24 attached. FIG. 25 is a sectional view taken along line KK in FIG. 24. FIG. 26 is a sectional view taken along line JJ in FIG. 21.

As shown in FIG. 20, the attachment 24 includes an attachment side connection port 47 and an attachment outer shell 100.

The attachment side connection port 47 is a hollow cylindrical portion. The attachment-side connection port 47 is a connection port provided at one end of the attachment 24 . As shown in FIGS. 22 and 23, the attachment side connection port 47 can be connected to the main body side connection port 27. It can also be connected detachably. Note that the attachment side connection port 47 cannot be visually recognized in a state where it is connected to the main body side connection port 27. For example, it is not visible when viewed from the side as shown in FIGS. 22 and 23. As shown in FIG. 25, the attachment side connection port 47 includes a connection port inner wall 47a. The connection port inner wall 47a is the inner wall of the attachment side connection port 47. When the attachment side connection port 47 is connected to the main body side connection port 27, the inside of the connection port inner wall 47a functions as an internal air passage.

As shown in FIGS. 7 and 8, the main body 3 is removed from the tube body 4. Thereafter, the user can connect the main body side connection port 27 to the attachment 24 supported by the support device 2 by holding the handle 10 and moving the main body 3 (FIGS. 22 and 23). In the support device 2, the center of gravity of the base body 6, support body 7, and holder 8 is set at a low position so that it is difficult to fall. The user can connect the attachment 24 to the main body 3 by gripping the main body 3 and connecting the attachment-side connection port 47 of the attachment 24 supported by the support device 2 to the main-body side connection port 27. Therefore, the user can quickly and conveniently connect the attachment 24 and the main body 3 without touching the attachment 24.

As shown by dashed lines in FIGS. 21 and 25, the attachment 24 includes virtual axes X (virtual axis X1, virtual axis X2). The virtual axis X is, for example, an axis parallel to the direction in which the attachment side connection port 47 is attached to and removed from the main body side connection port 27. The virtual axis X is, for example, an axis parallel to the intake direction or the exhaust direction in a state where the main body side connection port 27 and the attachment side connection port 47 are connected.

For example, the virtual axis X coincides with the central axis of the attachment side connection port 47. The virtual axis X is, for example, an axis that is parallel to the attachment/detachment direction and passes through the center of the connection port inner wall 47a of the attachment side connection port 47. For example, when the inner wall 47a of the connection port is circular, the imaginary axis X is the same as the center axis. For example, in the case of a rectangular shape, this is the intersection of the longitudinal midpoint and the lateral midpoint. In addition, if the shape is complex, it is a point where a midpoint in a specific longitudinal direction and a midpoint in a direction perpendicular to the longitudinal direction intersect. At least, the virtual axis X is arranged inside the connection port inner wall 47a of the attachment side connection port 47.

The support device 2 has an imaginary axis Y. Preferably, the support 7 of the support device 2 is provided with an imaginary axis Y. For example, the virtual axis Y extends in the vertical direction. For example, the virtual axis Y is parallel to the vertical direction. The virtual axis Y is, for example, an axis passing through the centroid of the cross section of the support 7. The centroid changes depending on the shape of the cross section, but as long as the centroid of the support body 7 is inside the cross-sectional view of the support body 7, the cross-sectional view may be of any part. The imaginary axis Y of the support body 7 is in a similar position in the connected holding body 8 (FIG. 21).

The attachment outer shell 100 is a portion of the attachment 24 other than the attachment side connection port 47. In a state where the attachment 24 is connected to the main body 3, the attachment side connection port 47 is covered by the main body side connection port 27. In this state, the attachment outer shell 100 is exposed to the outside. The attachment outer shell 100 includes an air passage forming part 48, a mounting part 49, and a support part 52.

The air passage forming part 48 is a hollow member. The inside of the air passage forming portion 48 functions as an internal air passage. The inside of the air passage forming part 48 and the connection port inner wall 47a are in communication.

The attachment portion 49 is for attaching the attachment 24 to the support device 2. In this embodiment, the air path forming part 48 and the mounting part 49 are arranged at separate positions. The mounting portion 49 is provided at a position close to the attachment side connection port 47. For example, when attached to the support device 2, the attachment portion 49 is located closer to the upper end of the attachment 24 than the lower end. The mounting portion 49 projects in a direction away from the virtual axis X. The mounting portion 49 is arranged at a position away from the virtual axis X. The tip of the attachment part 49, that is, the position of the attachment part 49 away from the virtual axis X, extends in the direction perpendicular to the direction of the virtual axis X and the direction in which the attachment part 49 projects.

The support portion 52 is provided between the air path forming portion 48 and the attachment portion 49. The support portion 52 protrudes from the air path forming portion 48 . The support portion 52 supports the attachment portion 49 .

The attachment part 49 has a large part 50 and a small part 51. The bulk portion 50 is a large, long portion. The small portion 51 is a small and thin portion. The large portion 50 is larger than the small portion 51. For example, the large portion 50 is long and the small portion 51 is small in the direction perpendicular to the direction of insertion into the support device 2. The large portion 50 is disposed closer to the distal end than the small portion 51. For example, the large portion 50 is located further away from the attachment side connection port 47 than the small portion 51 is. For example, the large portion 50 is located further away from the virtual axis X than the small portion 51.

Next, the attachment 24 will be explained using FIG. 21 and FIGS. 27 to 30 described above. FIG. 27 is a perspective view of the bristle brush 25 in the first embodiment. FIG. 28 is an exploded view of the bristle brush 25 in the first embodiment. FIG. 29 is a perspective view of the blower nozzle 26 in the first embodiment. FIG. 30 is a main part of a perspective view of the blower nozzle 26 in the first embodiment from another direction.

As mentioned above, the attachment 24 includes a bristle brush 25 and a blower nozzle 26. The bristle brush 25 includes a bristle brush side connection port 78, a bristle brush connection port inner wall 78a, a bristle brush air passage forming part 79, a bristle brush attachment part 80, and a bristle brush support part 83. The blower nozzle 26 includes a nozzle side connection port 91, a nozzle connection port inner wall 91a, a nozzle air path forming section 92, a nozzle mounting section 93, and a nozzle support section 96. The bristle brush side connection port 78 and the nozzle side connection port 91 are the attachment side connection port 47. The bristle brush connection port inner wall 78a and the nozzle connection port inner wall 91a are the connection port inner wall 47a of the attachment 24. The bristle brush air path forming section 79 and the nozzle air path forming section 92 are the air path forming section 48 of the attachment 24 . The bristle brush attachment part 80 and the nozzle attachment part 93 are the attachment part 49 of the attachment 24. The bristle brush support 83 and the nozzle support 96 are the support 52 of the attachment 24.

The support portion 52 is made up of at least a plurality of plate-like members. The plurality of plate-like members include, for example, a first plate 53 and a second plate 54. The first plate 53 and the second plate 54 are at least in contact with each other. Also, they may intersect with each other.

When viewed from the direction in which the first plate 53 and the second plate 54 protrude from the air path forming portion 48, the first plate 53 and the second plate 54 are perpendicular to each other, for example. For example, go straight in a T shape. For example, intersect. For example, they intersect in the shape of a cross.

The small portion 51 consists of one or more plate-like members. The small portion 51 is supported by a support portion 52 .

The small portion 51 or the support portion 52 has a third plate 56 . The third plate 56 is a plate-like member. The large portion 50 is supported by a small portion 51 and a third plate 56. The small portion 51 and the third plate 56 are at least in contact with each other. Also, they may intersect with each other.

For example, the small portion 51 and the third plate 56 are perpendicular to each other when viewed from the direction in which they protrude from the air path forming portion 48 . For example, go straight in a T shape. For example, intersect. For example, they intersect in the shape of a cross.

As described above, the large portion 50 and the small portion 51 are supported by two or more plate-like members. Further, the support portion 52 itself is also two or more plate-like members that are in contact with each other. Therefore, the large portion 50, the small portion 51, and the support portion 52 have a strength that prevents them from being damaged even if force is applied during installation.

Next, the bristle brush 25 will be explained using FIGS. 27 and 28.
The bristle brush 25 is a suction attachment. The bristle brush 25 uses suction air. The bristle brush 25 includes a bristle brush suction port 84 . The bristle brush suction port 84 is an opening that sucks in dust. The bristle brush 25 has a plurality of bristle bundles 75 at its tip. The bristle bundle 75 is arranged around the bristle brush suction port 84. The hair bundle 75 is, for example, a plurality of hair bundles 75. The bristle brush 25 has a function as a brush, for example, and scrubs the surface to be cleaned and dust on the surface to be cleaned. In other words, suction and sweeping are performed at the same time. When the dust on the surface to be cleaned is rubbed, the adhesion to the surface to be cleaned is reduced. This makes it easier to attract dust.

The bristle brush 25 includes a bristle brush side connection port 78, a latch 76, and a spring 77. The bristle brush side connection port 78 is the attachment side connection port 47. The bristle brush side connection port 78 is connected to the suction port 28 by being inserted thereinto. The latch 76 and spring 77 of the bristle brush 25 have the same function as the latch 42a and spring 43c of the tube body 4. That is, the latch 76 and spring 77 of the bristle brush 25 maintain the state of connection with the suction port 28 and the tube body 4, and this connection can be easily released by the user's operation.

The bristle brush side connection port 78 has a hollow cylindrical shape. At least a portion of the bristle brush side connection port 78 has a cylindrical shape. The bristle brush side connection port 78 has a central axis. Further, the bristle brush 25 connection port 78 includes a bristle brush connection port inner wall 78a. The bristle brush connection port inner wall 78a is one of the connection port inner walls 47a of the attachment 24. The bristle brush connection port inner wall 78a is the inner wall of the bristle brush connection port 78. For example, the bristle brush side connection port 78 has a central axis of the bristle brush connection port inner wall 78a. The bristle brush 25 has an imaginary axis X1. The virtual axis X1 is one of the virtual axes X of the attachment. The virtual axis X1 is, for example, parallel to the central axis of the bristle brush 25. The virtual axis X1 coincides with the central axis of the bristle brush 25, for example. The virtual axis X1 is, for example, an axis parallel to the suction direction inside the bristle brush side connection port 78.

The bristle brush 25 is provided with a bristle brush attachment part 80. The bristle brush attachment part 80 is for attaching the bristle brush 25 to the support device 2. The bristle brush attachment portion 80 is located closer to the bristle brush side connection port 78 than the bristle brush suction port 84 . A bristle brush mount 80 is provided on the opposite side of the latch 76. That is, when cleaning the surface to be cleaned, the bristle brush attachment portion 80 is placed closer to the surface to be cleaned than the latch 76. Note that the position of the bristle brush attachment portion 80 is not limited to this embodiment.

Next, the blower nozzle 26 will be explained using FIGS. 29 and 30. The blower nozzle 26 is a blower attachment. The blower nozzle 26 is an attachment 24 that uses exhaust air to blow away dust on the surface to be cleaned. The blower nozzle 26 has a hollow tubular shape. The blower nozzle 26 has an elongated shape.

The blower nozzle 26 includes a nozzle-side connection port 91 and a latch 89 on the upper end side, and an air outlet 90 on the lower end side. The nozzle side connection port 91 is the attachment side connection port 47. The nozzle side connection port 91 is connected to the exhaust port 29 by being inserted thereinto. The outlet 90 is for blowing out the exhaust air that has flowed in from the nozzle side connection port 91 to the outside of the main body 3. The blower nozzle 26 has a tapered shape from the nozzle side connection port 91 to the blower outlet 90. The latch 89 maintains the connection between the exhaust port 29 and the nozzle side connection port 91, and allows the connection to be easily released by the user's operation. The blower nozzle 26 includes a nozzle mounting portion 93. The nozzle attachment part 93 is for attaching the blower nozzle 26 to the support device 2. The nozzle mounting portion 93 is arranged at a position closer to the nozzle-side connection port 91 than the air outlet 90.

Blower nozzle 26 has a virtual axis X2. The virtual axis X2 is one of the virtual axes X of the attachment. The virtual axis X2 is, for example, the longitudinal axis of the blower nozzle 26. The virtual axis X2 is, for example, an axis parallel to the direction of attachment and detachment between the exhaust port 29 and the nozzle side connection port 91. The virtual axis X2 is, for example, an axis parallel to the blowing direction of the blower. For example, in a cross section perpendicular to the blowing direction, the virtual axis X2 and the center of gravity are arranged inside the connection port inner wall 47a.

Next, the state in which the attachment 24 is attached to the main body 3 will be described using FIGS. 31 to 33. FIG. 31 is a side view showing a state in which the bristle brush 25 is attached to the main body 3 in the first embodiment. FIG. 32 is a side view showing a state in which the blower nozzle 26 is attached to the main body 3 in the first embodiment. FIG. 33 is a side view showing how the blower nozzle 26 is attached to and detached from the main body 3 in the first embodiment.

As shown in FIGS. 31 to 33, with the attachment 24 attached to the main body 3, the attachment portion 49 is preferably disposed on the front side or the rear side. That is, the mounting portion 49 is visible in the side view in FIGS. 31 to 33 and also in the side view in the opposite direction from FIGS. 31 to 33. Therefore, it has excellent symmetry.

As shown in FIG. 31, the bristle brush 25 is used by being connected to the suction port 28 of the main body 3. When the bristle brush 25 is connected to the main body 3 to clean a horizontal surface, the main body 3 assumes a position similar to that shown in FIG. That is, the front part of the main body 3 is arranged above the rear part. Further, the bristle brush attachment part 80 is arranged on the rear side, and the latch 89 is arranged on the front side.

As shown in FIGS. 32 and 33, the blower nozzle 26 can be connected to the main body 3 by moving upward. When the nozzle side connection port 91 is inserted into the exhaust port 29, the latch 89 engages the edge of the exhaust port 29, and the connected state of the exhaust port 29 and the blower nozzle 26 is maintained. When the user presses the latch 89, the connection between the exhaust port 29 and the blower nozzle 26 is released. The blower nozzle 26 can be removed from the main body 3 by moving the blower nozzle 26 away from the main body 3 with the exhaust port 29 and the blower nozzle 26 disengaged. The direction of removal is downward, in other words, the direction opposite to the direction of attachment.

When the electric blower 16 is driven with the blower nozzle 26 attached to the exhaust port 29, exhaust air enters the blower nozzle 26 from the exhaust port 29. The exhaust air is then blown out from the outlet 90. The user can blow away dust and the like by holding the handle 10 and directing the air outlet 90 toward the surface to be cleaned.

Further, as shown in FIG. 15 described above, a shutter section 30 is attached to the exhaust port 29. The shutter section 30 is a plate-like member, and has a grid shape with a plurality of holes. The shutter section 30 is attached to be able to open and close the exhaust port 29. The shutter section 30 is attached to the edge of the exhaust port 29 via a rotation shaft 31 on one side thereof. The shutter portion 30 is movable between a position in which the exhaust port 29 is closed and a position in which the exhaust port 29 is opened by rotating inside the outer shell portion 9 about the rotation axis 31.

The shutter section 30 adjusts the opening area of the exhaust port 29. At the position where the shutter section 30 is open, the opening area of the exhaust port 29 is large and air resistance is small. On the other hand, when the shutter section 30 is closed, the air is exhausted from the plurality of holes. The total opening area of the plurality of holes is smaller than the opening area when the shutter section 30 is open. Therefore, air resistance is large when the shutter section 30 is closed.

When attaching and detaching the blower nozzle 26 to and from the exhaust port 29, the blower nozzle 26 is inserted and removed in a direction perpendicular to the exhaust port 29. The rotation axis 31 of the shutter section 30 is parallel to the opening surface of the exhaust port 29. Therefore, the rotation axis 31 is perpendicular to the direction in which the blower nozzle 26 is attached to and removed from the exhaust port 29.

The shutter section 30 is biased to close the exhaust port 29 by, for example, a spring. Therefore, as shown in FIG. 15, when the blower nozzle 26 is not attached to the exhaust port 29, the shutter section 30 closes the exhaust port 29.

When the blower nozzle 26 is inserted into the exhaust port 29, the shutter part 30 is pushed by the blower nozzle 26 and rotates inward of the outer shell part 9 about the rotation shaft 31. When the blower nozzle 26 is attached to the exhaust port 29, the shutter section 30 opens the exhaust port 29, and the above-described exhaust air passage of the main body 3 and the inside of the blower nozzle 26 are completely communicated with each other.

In this way, when the blower nozzle 26 is not attached to the exhaust port 29, the exhaust port 29 is closed by the shutter section 30. Therefore, the amount of exhaust from the exhaust port 29 is suppressed by the shutter section 30. In other words, by attaching the blower nozzle 26, the amount of exhaust air from the exhaust port 29 increases. Therefore, when cleaning by suction, the dust on the surface to be cleaned is not blown away due to the strong exhaust from the exhaust port 29.

Next, the attached portion 57 of the support device 2 will be explained using FIGS. 34 and 35. FIG. 34 is a main part of a side view of the holder 8 in the first embodiment. FIG. 35 is a top view of the support device 2 in the first embodiment.

FIG. 34 shows the top of the holder 8. The support device 2 includes an attached portion 57 of the attachment 24 . In this embodiment, the attached portion 57 is provided on the holder 8 . The attached portion 57 is provided on an extension of the support body 7, for example. The attached portion 57 is arranged at a higher position than the suction port 28 of the main body 3. The attached portion 57 has an opening. The attached portion 57 has, for example, an opening shaped like a "convex" upside down. The plate thickness of the attached portion 57 is thicker than the surrounding plate thickness. Thereby, the strength against attachment and detachment of the attachment 24 to and from the support device 2 can be increased. Further, even if the edges of the attached portion 57 are rounded, the wall does not become thin, and is excellent in terms of strength, prevention of cuts to the user, and prevention of damage to the attachment portion 49. The attached portion 57 opens substantially perpendicularly to the surface to be cleaned. Therefore, as shown in FIG. 35, the opening of the attached portion 57 cannot be visually recognized when viewed from above.

Next, the attachment 24 and the support device 2 will be described in more detail using the figures described above.

As shown in FIGS. 21 and 25, the attachment 24 is supported at an angle with respect to the support device 2. As shown in FIGS. For example, the virtual axis X of the attachment 24 is inclined with respect to the vertical direction. For example, the attachment 24 is tilted and supported by the support device 2 such that the horizontal distance between the imaginary axis X of the attachment 24 and the support device 2 increases upwardly.

Further, the horizontal distance between the attachment-side connection port 47 and the support device 2 is wider above the attachment-side connection port 47 than below. More specifically, the horizontal distance between the attachment-side connection port 47 and the support device 2 on the same plane is wider above the attachment-side connection port 47 than below. This makes it difficult for the main body 3 to come into contact with the support device 2 when the main body 3 approaches the attachment 24 supported by the support device 2 and connects the attachment side connection port 47 and the main body side connection port 27, making the connection easy. can. Note that the virtual axis X is inclined, for example, in a range of 0.5° to 10° with respect to the vertical direction.

As shown in FIG. 24, when the attachment 24 is attached to the support device 2, the attachment 24 is arranged inside the outer periphery of the support device 2 when viewed from above. In other words, the attachment 24 is not visible when viewed from below. Thereby, even when the attachment 24 is attached to the support device 2, the floor space required for installation does not increase.

In FIG. 34, the shape of the attached portion 57 is shown. The attached portion 57 is one opening configured with a plurality of shapes. For example, the openings of the attached portion 57 are made of rectangles of different sizes. The attached portion 57 includes an insertion position 58 and a restriction position 59. The large rectangular shape of the attached portion 57 is the insertion position 58, and the small rectangular shape is the restriction position 59. The insertion position 58 is an opening at a position where the mounting portion 49 of the attachment 24 can be inserted. In other words, the insertion position 58 is an opening through which the attachment portion 49 can be inserted into and removed from the support device 2 . The restriction position 59 is an opening at a position where the support device 2 supports the attachment 24 . That is, in a state where the attachment 24 is supported by the support device, the attachment 24 is arranged at the restriction position 59. Further, the restriction position 59 is a position that restricts the attachment 24 from moving in the horizontal direction.

The attachment portion 49 of the attachment 24 is movable between an insertion position 58 and a restriction position 59 while inserted into the attachment portion 57 . For example, it is possible to move between the insertion position 58 and the restriction position 59 by moving in a direction perpendicular to the insertion direction. In this embodiment, the moving direction is the vertical direction. Further, the insertion position 58 is arranged above the restriction position 59.

The attachment 24 remains supported by the support device 2. Further, the lower side of the attachment portion 49 is supported by an attached portion 57 . In other words, the attachment 24 is in a state where downward movement is restricted.

As described above, the large portion 50 is larger than the small portion 51. For example, when the attachment 24 is supported by the support device 2, the large portion 50 is long and the small portion 51 is small in the front-rear direction and the vertical direction. In this embodiment, when the attachment 24 is supported by the support device 2, the large portion 50 is long and the small portion 51 is small in the front-rear direction. The large portion 50 and the small portion 51 are smaller than the insertion position 58. That is, the large portion 50 and the small portion 51 can be inserted into the insertion position 58. On the other hand, the regulation position 59 is smaller than the large portion 50 and larger than the small portion 51. That is, when the attachment 24 is supported by the support device 2, it is impossible to insert or remove it in the horizontal direction. Therefore, by moving the attachment portion 49 from the insertion position 58 to the restriction position 59, movement of the attachment 24 in the horizontal direction is restricted. When the attachment 24 is inserted all the way, it is possible to move in a predetermined direction with the attachment 24 inserted. The predetermined direction is, for example, a downward direction.

The attachment part 49 is arranged at a position away from the attachment side connection port 47. Further, as described above, the virtual axis X is arranged inside the connection port inner wall 47a. On the other hand, the center of gravity of the attachment 24 is placed on or near the virtual axis X, for example. Moreover, the center of gravity is arranged inside the inner wall of the entire attachment 24, for example. Further, the center of gravity is arranged, for example, at a position close to the center in the longitudinal direction. In other words, the distance between the virtual axis X and the attachment portion 49 is greater than the distance between the virtual axis X and the center of gravity.

Furthermore, if there is nothing to restrict the movement of the attachment part 49, the attachment 24 rotates starting from the contact part between the attachment part 49 and the attached part 57 so that the center of gravity is located below the contact part.
However, since the side surface of the attachment 24 comes into contact with the support device 2, movement in the horizontal direction is restricted and the attachment 24 remains stationary. In this way, due to gravity, the center of gravity moves to be located below the contact point between the attachment part 49 and the attached part 57. Therefore, the attachment 24 is tilted.

As described above, when the attachment 24 is supported, movement of the support device 2 in the horizontal direction is restricted. However, when the virtual axis X of the attachment 24 is arranged in the vertical direction, there is a slight gap. In other words, there is a gap large enough to allow the attachment 24 to tilt. This allows for smooth attachment and detachment.

Further, as described above, the attachment 24 is supported by the support device 2 by two movements: one in the insertion direction and one movement perpendicular to the insertion direction. However, the restriction position 59 is located below the insertion position 58. That is, if the user releases his or her hand after inserting the attachment portion 49 into the insertion position 58, the attachment portion moves to the restriction position 59 due to gravity. That is, at the time of insertion, the user can cause the support device 2 to support the attachment 24 by moving only in one direction. In other words, when the user moves in one direction by hand, the direction in which insertion is possible changes to the direction in which movement is restricted.

The holding body 8 includes a partition wall portion 60 . The partition wall portion 60 is provided near the attached portion 57 . The partition wall portion 60 is disposed at the center of the support body 7 from the opening of the attached portion 57 . For example, the partition wall portion 60 prevents dust and foreign matter from entering the support body 7 through the mounting opening. When the attachment portion 49 is inserted into the attached portion 57 and in a state where the attachment portion 49 is supported, the attachment portion 49 may contact the partition wall portion 60 .

The sheet metal member 63 has a function of protecting the control section 62. Further, the sheet metal member 63 has a function of firmly fixing the base body 6 and the support body 7. For example, the sheet metal member 63 is made of a flame retardant material. For example, the sheet metal member 63 has a self-extinguishing property that burns while exposed to flame, but extinguishes when removed from the flame, making it difficult for the fire to spread. For example, the sheet metal member 63 is a steel plate with a thickness of 1.6 mm or more. Preferably, the sheet metal member 63 is a steel plate with a thickness of 2.0 mm or more. For example, the sheet metal member 63 is a steel plate made of SGHC material. The sheet metal member 63 covers the upper part of the control section 17, for example.

The spring 69 is connected to the left side holding part 68a and the right side holding part 68b. The spring 69 draws the left side holding part 68a and the right side holding part 68b toward each other by its initial tension. The spring 69 brings the left side holding part 68a and the right side holding part 68b closest when no external force other than its own force acts on the left side holding part 68a and the right side holding part 68b.

As shown in FIG. 41, the main body holding portion 66 includes a left side holding portion 71a, a right side holding portion 71b, a spring 72, and a supporting device side charging terminal portion 39.

A portion of the left side holding portion 71a and a portion of the right side holding portion 71b of the left side holding portion 71a are formed in a triangular shape when viewed from above. The left side holding part 71a and the right side holding part 71b are arranged at the same height. The left side holding part 71a and the right side holding part 71b are arranged symmetrically.

For example, spring 72 is a tension spring. It is arranged at the rear of the left shaft portion 73a and the right shaft portion 73b. The spring 72 is connected to the left side holding part 71a and the right side holding part 71b. The spring 72 draws the left side holding part 71a and the right side holding part 71b toward each other by the initial tension. The spring 72 brings the left side holding part 71a and the right side holding part 71b closest to each other when no external force other than its own force acts on the left side holding part 71a and the right side holding part 71b.

As shown in FIG. 41, the main body holding portion 66 includes a left side support device side charging terminal portion 74a and a right side support device side charging terminal portion 74b. The left side support device side charging terminal section 74a is provided below the slope section provided at the upper part of the left side holding section 71a. The right side support device side charging terminal portion 74b is provided below the slope portion provided at the upper part of the right side holding portion 71b.

The left support device side charging terminal portion 74a and the right side support device side charging terminal portion 74b are formed of triangular metal plates. The left side support device side charging terminal portion 74a and the right side support device side charging terminal portion 74b are formed to be tapered. The left side support device side charging terminal portion 74a and the right side support device side charging terminal portion 74b are formed such that the closer the distance between them in the left and right direction is, the smaller the depth width becomes. The left side support device side charging terminal portion 74a and the right side support device side charging terminal portion 74b are arranged at the same height. The left side support device side charging terminal portion 74a and the right side support device side charging terminal portion 74b are arranged symmetrically.

In FIG. 44, before the tubular body 4 comes into contact with the left holding part 68a and the right holding part 68b, the distance between the tip of the left holding part 68a and the tip of the right holding part 68b is smaller than the width of the latch part 38. It's also short. The distance between the tip of the left holding portion 68a and the tip of the right holding portion 68b is shorter than the width and the distance between the left recess 44a and the right recess 44b.

When the latch part 38 comes into contact with the left side holding part 68a and the right side holding part 68b and then moves so as to be pressed against the left side holding part 68a and the right side holding part 68b, the left side holding part 68a and the right side holding part 68b come into contact with each other. are displaced in a direction that increases the distance between them.

When the latch part 38 is further moved to be pressed against the left side holding part 68a and the right side holding part 68b, the tip of the left side holding part 68a and the tip of the right side holding part 68b are moved into the left side recess 44a and the right side recess 44b. Each is stored. At this time, the left side holding part 68a and the right side holding part 68b are displaced in a direction in which the distance between them becomes narrower. As a result, the tubular body 4 is held by the holder 8 while being sandwiched between the left side holding part 68a and the right side holding part 68b.

In a state in which the distal end of the left holding portion 68a and the distal end of the right holding portion 68b are housed in the left recess 44a and the right recess 44b, respectively, the left holding portion 68a and the right holding portion 68b are held together by the force of the spring 69. The left recess 44a and the right recess 44b are pressed together. Unless an external force other than the spring 69, such as an external force by a user, acts, the left holding part 68a and the right holding part 68b continue to press the left recess 44a and the right recess 44b together by the force of the spring 69. As a result, the tubular body 4 faces in the vertical direction while being held by the holder 8.

When the pipe portion 36 moves in a direction away from the holding body 8, the left holding portion 68a and the right holding portion 68b are displaced in a direction in which the distance between them increases. For example, when the pipe portion 36 moves rearward, the left holding portion 68a and the right holding portion 68b are displaced in a direction in which the distance between them increases. When the pipe portion 36 is detached from the left side holding portion 68a and the right side holding portion 68b, the left side holding portion 68a and the right side holding portion 68b are placed at a position where they are closest to each other due to the force of the spring 69.

Although details are not shown, in a state where the tubular body 4 is held by the holder 8, the lower surface of the first left regulating part 45a is arranged above the left holding part 68a. The lower surface of the first right regulating portion 45b is arranged above the right holding portion 68b. The upper surface of the second left regulating portion 46a is arranged below the left holding portion 68a. The upper surface of the second right regulating portion 46b is arranged below the right holding portion 68b.

The tube body 4 is supported by the left side first restriction part 45a and the right side first restriction part 45b coming into contact with the left side holding part 68a and the right side holding part 68b, respectively. Preferably, the tubular body 4 is supported by the left side first restriction part 45a and the right side first restriction part 45b contacting the upper end part of the left side holding part 68a and the upper end part of the right side holding part 68b, respectively.

When the tube body 4 moves upward while being held by the holding body 8, the left side second regulating part 46a and the right side second regulating part 46b are moved to the left side holding part 68a and the right side holding part 68b, respectively. Contact. Preferably, the left second restricting portion 46a and the right second restricting portion 46b contact the lower end portions of the left holding portion 68a and the right holding portion 68b, respectively. As a result, the tube body 4 is restricted from moving upward.

Moreover, regardless of whether or not the suction tool 5 and the pipe body 4 are connected, the left side first restriction part 45a and the right side first restriction part 45b are supported by the left side holding part 68a and the right side holding part 68b, respectively. As a result, the tubular body 4 is supported by the support device 2 without changing its posture and position.

When the suction tool 5 is supported by the support device 2 in a state where it is connected to the pipe body 4 and the main body 3, downward movement is restricted by the main body 3 and the holder 8 (FIG. 3). Further, when the main body 3 is removed and the tube body 4 and suction tool 5 are supported, downward movement is restricted by the suction tool 5 and the base body 6 (FIG. 10). Further, in a state where only the tube 4 is supported by the support device 2, downward movement is restricted by the tube 4 and the holder 8 (FIG. 12).

When the main body 3 is removed from the support device 2, the distance between the left support device side charging terminal portion 74a and the right side support device side charging terminal portion 74b is equal to the distance between the left side main body 3 side charging terminal portion 39L and the right side main body 3 side charging terminal. It is shorter than the distance from the portion 39R. When the main body 3 approaches the support device 2, the left main body 3 side charging terminal portion 39L and the right main body 3 side charging terminal portion 39R are connected to the left side support device side charging terminal portion 74a and the right side support device side charging terminal portion 74b, respectively. Contact. Thereafter, when the left side main body 3 side charging terminal section 39L and the right side main body 3 side charging terminal section 39R move so as to be pressed against the left side support device side charging terminal section 74a and the right side support device side charging terminal section 74b, respectively, the left side support The device-side charging terminal portion 74a and the right support device-side charging terminal portion 74b are displaced in a direction in which the distance between them increases. At this time, the left side holding part 71a and the right side holding part 71b are displaced in a direction in which the distance between them increases. When the main body 3 is supported by the support device 2, the main body holding portion 66 holds the left main body 3 side charging terminal portion 39L and the right main body 3 side charging terminal portion 39R so as to sandwich them therebetween. As a result, the main body 3 is stabilized while being supported by the support device 2. When the main body 3 is removed from the support device 2, the left side support device side charging terminal portion 74a and the right side support device side charging terminal portion 74b are arranged at a position where they are closest to each other due to the force of the spring 72.

Note that a portion of the left side holding portion 71a and a portion of the right side holding portion 71b have a triangular shape when viewed from above. Further, an inclined portion is formed at the upper part of the left holding part 71a and the upper part of the right holding part 71b. Therefore, even if the left main body 3 side charging terminal part 39L and the right main body 3 side charging terminal part 39R contact the left holding part 71a and the right holding part 71b from either above or from the rear, the left holding part 71a The distance between the right holding portion 71b and the holding portion 71b increases. Moreover, even if the main body 3 moves in either direction, upward or backward, the main body 3 comes off from the support device 2.

When the main body 3 is supported by the support device 2, the left main body 3 side charging terminal portion 39L and the right main body 3 side charging terminal portion 39R are the left side supporting device side charging terminal portion 74a and the right side supporting device side charging terminal portion 74b. come into contact with. As a result, the power supply path from the support device 2 connected to an external AC power source such as a commercial power source to the main body 3 is connected. At this time, the base body 6 converts AC power into DC power using a built-in power conversion circuit and supplies the DC power to the left side support device side charging terminal section 74a and the right side support device side charging terminal section 74b. The left main body 3 side charging terminal portion 39L and the right main body 3 side charging terminal portion 39R supply DC power to the battery via a lead wire (not shown) disposed inside the main body 3.

When the tube body 4 moves upward, the button part 43a moves upward while being pushed by the release part 67. As a result, latch 42a is placed in the second position. At this time, the latch portion 38 is disengaged from the fitting portion 19 of the connecting tube portion 14.

After the latch 42a is placed in the second position, when the tube body 4 further moves upward, the left side second restriction part 46a and the right side second restriction part 46b are moved to the left side holding part 68a and the right side holding part 68b, respectively. Contact. As a result, the tube body 4 is restricted from moving upward. When the main body 3 moves further upward, the main body 3 is detached from the tube body 4.

When the main body 3 approaches the support device 2 from above in a state where the tube body 4 is supported by the support device 2, the latch tip portion 43b comes into contact with the fitting portion 19 of the connecting tube portion 14. Thereafter, when the main body 3 is brought closer to the support device 2 from above, the main body 3 and the tube body 4 are connected. Furthermore, the main body 3 and the support device 2 are connected.

Note that when the tubular body 4 and the holding body 8 are attached and detached, no external force other than the force from the spring 43c acts on the latch portion 38. At this time, the latch 42a remains in the first position.

According to the first embodiment described above, the attachment 24 is supported by the support device 2. For example, the support device 2 supports the attachment shell 100 of the attachment 24. For example, the attachment side connection port 47 is visible when viewed from above. For example, the inside of the attachment-side connection port 47, for example, the connection port inner wall 47a, is visible. Preferably, the inside of the attachment-side connection port 47, for example, the connection port inner wall 47a, is visible when viewed from above. For example, the attachment side connection port 47 is in a state facing upward. In other words, the attachment 24 is supported by the support device 2 in a state where it can be connected to the main body 3. In other words, the attachment side connection port 47 is supported by the support device 2 in a state where it can be connected to the main body side connection port 27. Note that the state in which the attachment side connection port 47 faces upward is not limited to the state in which it opens in the vertical direction. For example, this includes a state in which the attachment side connection port 47 is tilted within a range of -45° to 45° from the vertical direction. For example, this includes a state in which the virtual axis X is tilted within a range of -45° to 45° from the vertical direction. As a result, the user can connect the attachment 24 to the main body 3 by grasping the main body 3 and connecting the attachment side connection port 47 of the attachment 24 supported by the support device 2 to the main body side connection port 27. Therefore, the user can quickly and conveniently connect the attachment 24 and the main body 3 without touching the attachment 24.

Further, the mounting portion 49 is disposed at a position closer to the upper end of the attachment 24 than the lower end while being supported by the support device 2 . Further, the attachment portion 49 is arranged at a position closer to the attachment side connection port 47 than the bristle brush suction port 84 or the blowout port 90. As a result, when a force is applied to the attachment-side connection port 47, the attachment part 49 is located close to the attachment part 49, so that force is hardly applied to the attachment part 49 or the attached part 57 due to the lever principle. Therefore, the attachment 24 and the support device 2 are less likely to be damaged.

The attachment 24 also includes a virtual axis X. The virtual axis X is, for example, an axis parallel to the direction of attachment and detachment between the attachment side connection port 47 and the main body side connection port 27. Further, the virtual axis X is, for example, an axis parallel to the intake direction at the suction port 28 or the exhaust direction at the exhaust port 29. The attachment 24 is supported by the support device 2 with the virtual axis X being inclined with respect to the vertical direction. The support device also includes a virtual axis Y. For example, the virtual axis Y is parallel to the vertical direction. The virtual axis Y is arranged, for example, inside the support body 7. The attachment 24 is tilted and supported by the support device 2 so that the distance between the virtual axis X of the attachment 24 and the virtual axis Y of the support body 7 of the support device 2 increases upwardly. For example, when the virtual axis X is supported by the support device 2 in a state parallel to the vertical direction, the user connects the main body 3 to the attachment 24 along the support device 2. In this case, if the main body 3 and the support device 2 come into contact with each other, there is a risk of the device falling over or damage to both may occur. Therefore, the user needs to move the main body 3 carefully. On the other hand, when the virtual axis X of the attachment 24 is inclined with respect to the virtual axis Y of the support body 7 of the support device 2 as described above, the distance between the main body 3 and the support device 2 is such that the virtual axis apart from the case parallel to the direction. Therefore, the main body 3 is unlikely to come into contact with the support device 2, and the user can easily connect the main body 3 to the attachment 24.

Further, the attachment 24 is tilted and supported by the support device 2 so that the horizontal distance between the attachment-side connection port 47 and the support device 2 is wider above the attachment-side connection port 47 than below. Note that depending on the structure of the attachment 24, the upper side may be closer to the support device 2 than the lower side. However, the distance between the attachment side connection port 47 and the support device 2 increases as it goes upward. In addition, the attachment is attached to the support device 2 so that the shortest distance in the horizontal direction between the connection port inner wall 47a or the internal air passage of the attachment side connection port 47 and the support device 2 is farther apart at the top than at the bottom of the attachment side connection port 47. 24 is supported at an angle. This makes it difficult for the main body 3 to come into contact with the support device 2 when connecting the main body 3 to the attachment 24 supported by the support device 2 . Therefore, the user can easily connect the main body 3 to the attachment 24.

Further, the support device 2 includes a restriction means that restricts horizontal and downward movement of the attachment 24 while the attachment 24 is supported by the support device 2. Thereby, when the user connects the main body 3 to the attachment 24 supported by the support device 2, the attachment 24 does not move downward. Moreover, the attachment 24 will not fall when force is applied in the horizontal direction before the main body side connection port 27 and the attachment side connection port 47 are completely connected. Therefore, it is possible to connect smoothly and is easy to use. Moreover, when force is applied to the support device 2 in the horizontal direction, the attachment 24 will not fall. Therefore, stability is high.

Further, in a state where the attachment 24 is attached to the support device 2, the attachment 24 is arranged inside the outer periphery of the support device 2 when viewed from above. In other words, the attachment 24 is not visible when viewed from below. Thereby, even when the attachment 24 is attached to the support device 2, the floor space required for attachment does not increase. Furthermore, since it is difficult for the user to accidentally touch the attachment 24, safety is high. Moreover, even if the downward force for attachment is strong, the support device 2 will not fall over.

Further, the holding body 8 supports the main body 3 by the support device 2 as the main body 3 moves downward while holding the pipe body 4 in a state where the pipe body 4 is removed from the main body 3. Also, the main body 3 and the tube body 4 are connected. That is, in a state where the tube body 4 and the attachment 24 are supported by the support device 2 and a state where the main body 3 is removed from the support device 2, the body 3 is selectively connected to the tube body 4 and the attachment 24. It is possible. Thereby, for example, if the user connects the main body 3 to the attachment 24 after cleaning, the user can proceed to cleaning with the attachment 24 connected. Further, when connected to the pipe body 4, cleaning can be performed with the pipe body 4 connected. Further, when connected to the pipe body 4 and installed on the support device 2, the vacuum cleaner 1 is supported by the support device 2.

It is possible. As a result, attachment is easy, and when the attachment 24 is supported by the support device 2, movement in the horizontal direction is restricted, resulting in a so-called locked state, and the attachment 24 is unlikely to fall. This makes it easy to use.

The attachment portion 49 includes a large portion 50 and a small portion 51 smaller than the large portion 50. Furthermore, the small portion 51 is located closer to the air path forming portion 48 than the large portion 50. Further, the large portion 50 is disposed further away from the small portion 51 with respect to the virtual axis X or the connection port inner wall 47a. The large portion 50 and the small portion 51 are smaller than the opening at the restriction position 59. The large portion 50 is larger than the opening at the restriction position 59. This makes it difficult for the attachment 24 to fall when the mounting portion 49 is placed at the restriction position 59. This makes it easy to use.

Further, with the bristle brush 25 connected to the main body 3, the bristle brush attachment part 80 is arranged on the rear side of the main body 3. As a result, the bristle brush attachment part 80 is difficult to see when cleaning surfaces to be cleaned such as floors and desks, and the appearance is not spoiled.

Alternatively, a suction attachment supported by the support device 2 may be connected to the tube body 4 connected to the main body 3 by gripping and operating the handle 10. This allows suction even in high places.

Moreover, the plurality of attached parts 57 of the support device 2 have symmetry. For example, the plurality of attached parts 57 are arranged at symmetrical positions when viewed from above. Further, for example, the plurality of attached parts 57 are arranged at symmetrical positions when viewed from the front. Preferably, the plurality of attached parts 57 have the same shape. The plurality of attached parts 57 are, for example, two attached parts 57. This prevents the appearance from being impaired.

Furthermore, when the main body 3 and the tube 4 are connected and the tube 4 is supported by the support device 2 and the main body 3 is moved upward, the main body 3 will come off from both the support device 2 and the tube 4. Good too. Furthermore, this allows the user to remove the main body 3 from the tube 4 without holding the tube 4 by hand.

The third plate 56 is a plate-like member. The large portion 50 is supported by a small portion 51 and a third plate 56. The small portion 51 and the third plate 56 are at least in contact with each other. Also, they may intersect with each other. Thereby, the large portion 50 is supported by the small portion 51 and the third plate 56. Therefore, the main portion 50 is unlikely to be damaged even if force is applied during installation.

Note that the main body 3 may be supported by the support device 2. For example, the support device 2 may support the dust collector 11 or the handle 10. For example, the main body 3 may be held at the same height as the upper end of the dust collecting section 11 or above the upper end. Further, for example, the main body 3 may be held above the lower end of the battery section 13. Preferably, the support device 2 may support the bottom of the dust collecting section 11 or the front of the handle 10. If the front part of the handle 10 has a bottom part, the bottom part may be supported. For example, a support portion 52 may be provided at the rear or upper portion of the support body 7, and the main body 3 may be held by the support portion 52. In other words, the support portion 52 may be provided directly above the support body 7 to hold the main body 3. Thereby, by supporting at least a portion of the main body 3 in addition to the pipe body 4, the stability of the vacuum cleaner system can be improved. Only the main body 3 from which the tube body 4 has been removed can be supported by the support device 2, and the versatility of the vacuum cleaner system can be expanded. Furthermore, by holding the vacuum cleaner 1 at a high position, the vacuum cleaner 1 becomes difficult to come off from the support device 2. In addition, by gripping the upper side of a heavy object such as a battery, it becomes difficult for the object to come off the support device 2. As a result, it is possible to improve the usability of the vacuum cleaner system.

Further, the support device 2 may support the bottom of the dust collecting section 11. For example, when the main body 3 and the tube body 4 are connected to the support device 2 in a connected state, the dust collecting section 11 may be slightly lifted from the holder 8. For example, when the main body 3 is disconnected from the tube body 4, the support device 2 may support the main body 3 directly below the center of gravity. In other words, when the main body 3 is disconnected from the pipe body 4, the bottom of the dust collecting section 11 may be supported by the support device 2. Preferably, it is supported on the upper surface of the holder 8. However, it is not necessary to directly support the center of gravity of the main body 3. For example, it may be supported on a circular arc, and the center of gravity in top view may be located inside the circular arc. For example, it is sufficient if it is supported at three or more points and the center of gravity in a top view is inside a rectangle connecting each point. This places the center of gravity within the supported area and prevents it from tipping over. In addition, the stability when the main body 3 is installed on the support device 2 can be improved, and it is easy to use.

Further, the support device 2 holds the tube 4 in a state in which the tube 4 is connected to the main body 3 and in a state in which the tube 4 is released from the connection with the main body 3. Preferably, the holder 8 holds the tube 4. At this time, the holder 8 holds the tube 4 regardless of whether the suction tool 5 is connected to the tube 4 or not. In other words, the support device 2 can support only the tube body 4. Therefore, when the main body 3 is used in a state where it is released from the connection with the tube body 4, the tube body 4 can be maintained in a state held by the support device 2. Further, for example, when the suction tool 5 is directly connected to the main body 3 while cleaning with the vacuum cleaner 1, the removed tube body 4 can be supported by the support device 2. As a result, no space other than the support device 2 is required to place the tubular body 4, and there is no need to worry about where to place the tubular body 4.

Further, in a state where the holder 8 holds the tube 4, at least one of the holder 8 and the tube 4 restricts the tube 4 from moving upward. For example, the tube body 4 includes a left side second restriction part 46a and a right side second restriction part 46b. At this time, the holder 8 holds the tube 4 with the attachment/detachment direction of the tube 4 being in the horizontal direction. When the main body 3 moves upward in a state where the tube 4 and the main body 3 are connected, the left second restriction portion 46a and the right second restriction portion 46b restrict the upward movement of the tube 4. As a result, only the main body 3 moves upward, and the main body 3 is removed from the tube body 4. Therefore, by changing the direction of movement and removal of the main body 3, cleaning of only the main body 3 and cleaning with the main body 3 and the pipe body 4 connected can be selected.

Furthermore, when the tube 4 is moved upward while holding the tube 4, the holding body 8 releases the connection between the tube 4 and the main body 3 by changing the position of the latch 42a of the tube 4. . When the tube body 4 moves further upward, the upward movement of the tube body 4 is restricted. In this case, even when the latch portion 38 is provided, the tube 4 and the main body 3 can be easily attached and detached. For example, if the user moves the main body 3 upward while holding the handle 10, the main body 3 is removed from the support device 2 while the tube 4 is held by the support device 2. Therefore, by changing the direction of movement and removal of the main body 3, cleaning with only the main body 3 or cleaning with the main body 3 and the tubular body 4 connected can be selected.

Further, the latch portion 38 may be provided on the main body 3. Moreover, the release part 67 may be in a state in which the tube body 4 is installed on the support device 2 and the button part 43a is pressed. In other words, the latch 42a may be in the second position when the tube body 4 is installed on the support device 2. In other words, even when the tube body 4 to which the main body 3 is connected is supported by the support device 2, the latch 42a may be placed at the second position. As a result, there is less friction and resistance when moving the main body 3 upward, and the main body 3 can easily come off the tube body 4, making it possible to remove it even more easily.

Further, the orientation of the cleaner 1 is not limited to this embodiment. For example, the rear of the vacuum cleaner 1 may be located closer to the support body 7 than the front of the vacuum cleaner 1.

Further, the battery may be charged via a plug to a power supply means (not shown). For example, a plug may be connected to the support device 2 and connected to the main body 3 via a terminal. Even in this case, the battery can be charged. Also,

In addition, in this Embodiment, the dust collection part 11 demonstrated the example which has the cyclone separator which performs centrifugation. However, the method for separating and accumulating dust is not limited to this, as long as the dust collecting section 11 separates dust from dust-containing air and accumulates the separated dust. For example, dust and air may be separated by a filter without centrifugation. Alternatively, a so-called paper pack type may be used.

Note that the suction attachment is not limited to the bristle brush 25. Further, the blower attachment is not limited to the blower nozzle 26. The blower attachment can be of any shape to be connected to the exhaust port 29. For example, the blower nozzle 26 may include a joint part that can change the blowing direction.

Note that the suction port 28 and the exhaust port 29 may have the same shape. Further, the nozzle side connection port 91 and the bristle brush side connection port 78 may have the same shape. That is, a suction attachment may be connected to the exhaust port 29, and a blower attachment may be connected to the suction port 28. That is, the attachment 24 may be a dual-purpose attachment 24 that can be connected to both the suction port 28 and the exhaust port 29. For example, by connecting a blower attachment to the suction port 28, cleaning of gaps is excellent. This expands versatility.

In this embodiment, a blower attachment is connected to the exhaust port 29 located at a different position from the suction port 28. That is, the suction port 28 uses suction air directed toward the electric blower, and the exhaust port 29 uses exhaust air from the electric blower. However, the exhaust air from the electric blower may be blown out from the suction port 28 by switching the air path. For example, the main body 3 may have an air passage switching structure. In this case, by connecting a blower attachment to the suction port 28, it can be used as a blower. It is also possible to use the blower attachment as a suction attachment. Therefore, it is easy to use.

Further, the device may include only either a suction attachment or a blower attachment. Moreover, the main body 3 does not need to be provided with the exhaust port 29 to which the blower attachment is connected. Further, the support device 2 may support a plurality of suction attachments. Further, the support device 2 may support a plurality of blower attachments.

Furthermore, in the embodiment described above, an example has been described in which movement in the horizontal direction is restricted by moving the attachment part 49 downward after inserting it into the attachment target part 57. However, the attachment method is not limited. For example, it may move upward or laterally. It may also be rotated after insertion. Further, it may be moved in a plurality of directions after insertion.

Further, it may be inserted diagonally into the opening of the attached portion 57. For example, if it has a bent or curved shape like an "L", "U", "S", or "K" shape, it is easy to insert it diagonally. Furthermore, in this case, it becomes difficult to move horizontally due to gravity at the time of insertion, so it is difficult to fall. Therefore, insertion and horizontal movement can be restricted by movement in one direction including insertion. Therefore, it is easy to use.
