Duplicate description of the parts will be simplified or omitted as appropriate. Furthermore, the present invention is not limited to the following embodiment, and various modifications are possible without departing from the spirit of the present invention. In the following description, air that has been mixed with dust is called "dust-containing air". Air from which dust has been removed is called "clean air". Furthermore, attachments are omitted (not shown) in some drawings.

Embodiment 1.
Fig. 1 is a perspective view of the vacuum cleaner system in accordance with embodiment 1. Fig. 2 is a top view of the vacuum cleaner system in accordance with embodiment 1. Fig. 3 is a side view of the vacuum cleaner system in accordance with embodiment 1.

As shown in FIG. 1, the vacuum cleaner system includes a vacuum cleaner 1 and a support device 2. The up-down, front-back, left-right directions of the cleaning system are as shown in FIG. 1 and FIG. 2.

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

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

For example, the tube 4 is formed in a rod shape. The tube 4 extends downward from the main body 3. The upper end of the tube 4 is detachably attached to the rear of the main body 3. The rear and widthwise middle part of the suction tool 5 is detachably attached to the lower end of the tube 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 the contents common to the suction attachment and the blower attachment are collectively described as attachment 24.

The attachment 24 is removably attached to the support device 2. The upper end of the bristle brush 25 is removably attached to the rear of the main body 3. The upper end of the blower nozzle 26 is removably attached to the 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 room. For example, the support device 2 is a charging stand for charging the vacuum cleaner 1. A part of the support 7 is formed of a metal member. For example, a part of the support device 2 is formed of a steel plate. The support 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 6 is disposed at the lowest position in the support device 2. For example, the base 6 is placed on the floor surface near the wall of a living room. For example, the support 7 is columnar. For example, the lower end of the support 7 is fixed to the base 6. The holder 8 is disposed above the base 6. For example, the holder 8 is disposed 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 center of gravity of the base 6, support 7, and holder 8 is set at a low position so that the support device 2 is less likely to tip over when the vacuum cleaner 1 is attached or detached. Specifically, the base 6 is heavier than the support 7. The base 6 is heavier than the holder 8. The base 6 may be heavier than the combined weight of the support 7 and holder 8. In other words, the mass of the base 6 is greater than the combined mass of the support 7 and holder 8. This lowers the center of gravity, making the support device 2 and the vacuum cleaner system less likely to tip 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 6 of the support device 2. In this case, the rear end of the suction tool 5 is positioned rearward 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 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. 3.

The user may also rotate the main body 3 in direction B without lifting the main body 3 upward. Immediately after rotating in direction B, the main body 3 moves in direction A. As a result, the tube body 4 becomes inclined relative to the surface to be cleaned. This allows the vacuum cleaner 1 to quickly transition to the cleaning mode.

When the vacuum cleaner 1 is removed from the support device 2 as a handheld vacuum cleaner 1, the user moves the main body 3 in the direction C. At this time, the tube body 4 is pulled by the main body 3 and moves in the direction C. Therefore, even if the main body 3 moves in the direction C, 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 the support device 2.

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 handheld vacuum cleaner. For example, the user attaches and detaches the main body 3 by moving it laterally relative to the support device 2. For example, the user attaches and detaches the main body 3 by moving it up and down relative to the support device 2.

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 connected to the tube 4.

When the vacuum cleaner 1 is supported by the support device 2, a portion of the main body 3 is positioned directly above the suction tool 5. This allows the vacuum cleaner 1 and the support device 2 to be installed in a narrow space.

Next, a first example of use of the vacuum cleaner 1 will be described with reference to FIG. 4. FIG. 4 is a perspective view showing a first example of use of the vacuum cleaner 1 in embodiment 1. 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 casing 9 is part of the design surface of the vacuum cleaner 1. As shown in Figures 3 and 4, the handle 10 determines the front-to-rear direction of the vacuum cleaner system. The upper end of the handle 10 is located above the outer casing 9. The dust collection unit 11 is formed into a cylindrical shape overall. The dust collection unit 11 is located below the outer casing 9.

When the vacuum cleaner 1 is used as a stick vacuum cleaner, the user holds the middle part of the handle 10. For example, the user cleans the floor surface with the longitudinal direction of the tube body 4 at an angle. In this case, the tube body 4 is positioned below the main body 3.

Next, a second usage example of the vacuum cleaner 1 will be described with reference to FIG. 5. FIG. 5 is a side view showing a second usage example of the vacuum cleaner 1 in embodiment 1. 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 high places with the longitudinal direction of the tube body 4 facing diagonally upward.

Next, a third example of use of the vacuum cleaner 1 will be described with reference to Figures 6, 7, and 8. Figure 6 is a side view of the main body 3 in the first embodiment. Figures 7 and 8 are side views of 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 Figures 7 and 8, the vacuum cleaner 1 is used as a handheld vacuum cleaner as shown in Figure 6. The user cleans the surface to be cleaned with the tube body 4 and the suction tool 5 removed. In this case, the user holds the front end side of the handle 10.

Next, the procedure for supporting the vacuum cleaner 1 on the support device 2 will be described with reference to Figure 9. Figure 9 is a side view showing the state in which the suction tool 5 in embodiment 1 is placed at a specific position. Note that the attachment 24 is omitted (not shown) in Figure 9. For example, the suction tool 5 is placed at the specific position in a state in which it is loosely fitted into the base body 6.

The user tilts the main body 3 as shown in Figure 4, and holds the handle 10 to move the suction tool 5 back and forth. At this time, the vacuum cleaner 1 is positioned at an angle so that the suction tool 5 is in front of the main body 3. After cleaning is completed, the user moves the vacuum cleaner 1 forward while keeping it in the cleaning position, and places the suction tool 5 in 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 in the specific position, the main body 3 is positioned behind the suction tool 5. With the suction tool 5 placed in the specific position, the user moves the main body 3 and the tube body 4 in direction E. The movement in direction E is performed as a series of movements to move the vacuum cleaner 1 forward. The movement in direction E is a movement in which the user holds the handle 10 and moves the suction tool 5 in an arc around the axis of rotation. Therefore, the vacuum cleaner 1 is supported by the support device 2 without being lifted.

Next, modified examples of the vacuum cleaner system will be described with reference to Figures 10 to 13. Figure 10 is a side view of the state in which the tube body 4 and the suction tool 5 are supported by the support device 2 in embodiment 1. Figure 11 is a side view of the state in which the main body 3 and the tube body 4 are supported by the support device 2 in embodiment 1. Figure 12 is a side view of the state in which the tube body 4 is supported by the support device 2 in embodiment 1. Figure 13 is a side view of the state in which the main body 3 is supported by the support device 2 in embodiment 1. Note that the attachment 24 is omitted (not shown) in Figures 10 to 13.

As shown in FIG. 10, when the tube 4 and the suction tool 5 are connected, the tube 4 is held by the holder 8. As shown in FIG. 11, when the main body 3 and the tube 4 are connected, the tube 4 is held by the holder 8. As shown in FIG. 12, when the main body 3 and the suction tool 5 are not present, the tube 4 is held by the holder 8. As shown in FIG. 13, when the tube 4 and the suction tool 5 are not present, the main body 3 is held by the holder 8.

Next, the outer shell 9 and the handle 10 will be described with reference to Figures 14 and 15. Figure 14 is a vertical cross-sectional view of the vacuum cleaner 1 in embodiment 1. Figure 15 is a vertical cross-sectional view of the main body 3 in embodiment 1. As shown in Figures 14 and 15, the outer shell 9 includes a case section 12, a battery section 13, a connection tube section 14, and an exhaust section 15.

The case portion 12 is formed into a cylindrical shape overall. The case portion 12 houses the electric blower 16 and the control portion 17. The electric blower 16 is provided above the dust collection portion 11. The electric blower 16 is provided so as to be able to take in and exhaust air. The control portion 17 is provided directly above the electric blower 16. For example, the control portion 17 controls the operation of the electric blower 16. The case portion 12 has a protrusion 18. The protrusion 18 is provided at the front of the case portion 12.

The battery unit 13 is stored in the rear of the outer shell 9 below the rear end of the handle 10. The battery unit 13 is adjacent to the case unit 12. The battery unit 13 includes multiple secondary batteries. The voltages of the multiple secondary batteries are controlled by the control unit 17.

The connection pipe section 14 and the exhaust section 15 have, for example, a body side connection port 27. The attachment 24 can be freely connected to the body side connection port 27. The body side connection port 27 may be provided only on the connection pipe section 14. As will be described later, the body side connection port 27 provided on the connection pipe section 14 is an intake port 28, and the body side connection port 27 provided on the exhaust section 15 is an exhaust port 29.

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

The connection pipe portion 14 has a fitting portion 19. The fitting portion 19 is formed in a triangular shape in a side view. The fitting portion 19 protrudes outward from the connection pipe portion 14 as it moves upward.

An exhaust air passage is formed inside the main body 3. The exhaust air passage is the air passage 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, multiple exhaust sections 15 are provided. However, there may be only one exhaust section 15. In this embodiment, a first exhaust section 15a and a second exhaust section 15b are provided.

The second exhaust section 15b is formed at a position in the case section 12 where the battery section 13 is housed. In this configuration example, the second exhaust section 15b is provided on both sides of the case section 12. In other words, the second exhaust section 15b is disposed on the side of the main body 3.

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

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

The handle 10 is provided so as to be arranged so as to be visible in a top view when 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 front-rear direction of the main body 3. For example, the handle 10 is formed from the top end to the front. For example, the handle 10 is formed from the top end to the rear. For example, the handle 10 is formed from the top end to the front-rear. For example, the handle 10 is formed at a lower position forward than the top end. For example, the handle 10 is formed at a lower position rearward than the top end. For example, the handle 10 is formed so as to extend forward and backward from the center of the main body 3 in the front-rear 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 part of the handle 10 is curved and connected to the front end and rear end of the handle 10 above the case part 12. For example, the middle part of the handle 10 is formed so as to be convex upward. For example, the rear end of the handle 10 is provided on the extension line of the tube body 4, further rearward of the case part 12 than the rear part of the case part 12. For example, the front end of the handle 10 is provided on the front side of the case part 12 than the front part of the case part 12. For example, the front end of the handle 10 is connected to the convex part 18 of the case part 12.

Preferably, the handle 10 is disposed at the top of the main 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 portion of the handle 10. The space 20 is used when a user holds the handle 10 from above, and the user may grip the handle 10 with a hand or fingers inserted into the space 20.

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

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

The user operates the operation unit 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 operation content of the operation unit 21.

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

Next, the tube body 4 will be described with reference to 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 vertical cross-sectional view of the tube body 4 in the first embodiment. Fig. 19 is a cross-sectional view taken along line H-H in Fig. 17.

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

The pipe section 36 includes a pipe 40 and a fitting section 41. The pipe 40 is the main section of the pipe section 36. The pipe 40 is formed in a cylindrical shape. The inside of the pipe 40 serves as an air passage. The internal space of the pipe 40 has a longitudinal axis. The longitudinal axis is linear. The fitting section 41 is located at the front and bottom of the pipe section 36. The fitting section 41 is provided so as to be able to fit with a suction tool 5 not shown in FIG. 14.

The cover pipe 37 is connected to the rear of the pipe section 36. The outer shape of the cover pipe 37 is formed in a cylindrical shape. When the cover pipe 37 is connected to the pipe section 36, the outer shape of the pipe section 36 and the cover pipe 37 combined is a straight rod.

The latch portion 38 is disposed at the front and upper portion of the tube body 4. The latch portion 38 is provided on the outside of the pipe portion 36. For example, the latch portion 38 is fixed to the pipe portion 36 via a cover. For example, the latch portion 38 is fixed directly to the pipe portion 36. The center 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. 16. Specifically, the latch portion 38 is provided so as to be able to maintain the connection between the lower end of the connection tube portion 14 and the upper end 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 displaces like a seesaw. For example, the latch 42a displaces from a first position to a second position. For example, the latch 42a displaces from the second position to the first position. The first position is a position that maintains the connection between the main body 3 and the upper end of the pipe portion 36, which are not shown in FIG. 18. The second position is a position that releases the connection between the main body 3 and the upper end of the pipe portion 36.

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

When the button portion 43a is pressed toward the pipe portion 36, the latch 42a is displaced from the first position to the second position. When the latch tip portion 43b comes into contact with the fitting portion 19 of the main body 3, the latch 42a is displaced from the first position.

The cover latch 42b covers the latch tip 43b. For example, the cover latch 42b is inclined. For example, the cover latch 42b has a rounded shape. For example, the width of the cover latch 42b narrows as it moves away from the pipe portion 36. The cover latch 42b serves as a guide when the tube body 4 is held by the holder 8.

When the latch 42a is in the second position and the tube body 4 and the fitting portion 19 of the connecting pipe portion 14 move in a direction away from each other, the latch tip 43b is released from the fitting portion 19 of the connecting pipe portion 14. When the latch 42a is in the first position, the latch tip 43b fits into the fitting portion 19 of the connecting pipe portion 14. At this time, the protrusion 18 of the fitting portion 19 of the connecting pipe portion 14 prevents the pipe portion 36 from coming out of the connecting pipe portion 14. Furthermore, when the latch tip 43b moves away from the fitting portion 19 of the connecting pipe portion 14, the latch 42a returns to the first position by the force of the spring 43c.

When the tube 4 is inserted into the main body 3, the latch tip 43b comes into contact with the fitting portion 19 of the connecting tube section 14. When the tube 4 moves further toward the main body 3 from this state, the latch 42a changes from the first position. When the tube 4 moves further 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 4 is made without the need to operate the button portion 43a.

As shown in FIG. 19, the pipe portion 36 has a left recess 44a and a right recess 44b. For example, the left recess 44a and the right recess 44b are provided in 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 elongated recesses.

For example, the left recess 44a is formed on the surface of the pipe section 36 facing left. The right recess 44b is formed on the surface of the pipe section 36 facing right. In contrast, the latch portion 38 is provided on the surface of the pipe section 36 facing forward. When the tube body 4 is viewed from above, the latch portion 38 is disposed between the left recess 44a and the right recess 44b.

The left recess 44a and the right recess 44b are positioned at the same height. For example, the left recess 44a and the right recess 44b are positioned 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 tube body 4 includes a left first restricting portion 45a, a right first restricting portion 45b, a left second restricting portion 46a, and a right second restricting portion 46b. The left first restricting portion 45a and the left second restricting portion 46a are disposed on the far side of FIG. 17. For this reason, the left first restricting portion 45a and the left second restricting portion 46a are not shown in FIG. 17.

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

The left first restricting portion 45a is disposed at the upper end of the left recess 44a. The right first restricting portion 45b is disposed at the upper end of the right recess 44b. The left first restricting portion 45a and the right first restricting portion 45b are disposed at the same height. The left recess 44a is disposed at the back side of FIG. 17. For this reason, the left recess 44a is not shown in FIG. 17.

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

The terminal portion 39 is disposed at the rear and upper portion of the tube body 4. The terminal portion 39 is an intermediate part for passing electricity to the suction tool 5, which is not shown in FIG. 17. The terminal portion 39 is connected to a lead wire, which is not shown in FIG. 17. A part of the terminal portion 39 and the lead wire are disposed between the pipe portion 36 and the cover pipe 37.

Next, the state in which the attachment 24 is supported on the support device 2 will be described with reference to 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 rear view of the attachment 24 attached to the support device 2 in the first embodiment. 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 attachment 24 attached to the support device 2 in the first embodiment. Fig. 25 is a cross-sectional view taken along the line K-K in Fig. 24. Fig. 26 is a cross-sectional view taken along the line J-J in Fig. 21.

As shown in FIG. 20, the attachment 24 has 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. The attachment side connection port 47 cannot be seen when connected to the main body side connection port 27. For example, it cannot be seen in a side view as shown in Figs. 22 and 23. As shown in Fig. 25, the attachment side connection port 47 has 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 Figures 7 and 8, the main body 3 is removed from the tube 4. The user then holds the handle 10 and moves the main body 3 to connect the main body side connection port 27 to the attachment 24 supported by the support device 2 (Figures 22 and 23). The center of gravity of the base 6, support 7, and holder 8 of the support device 2 is set at a low position so that it is less likely to tip over. 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. This allows the user to quickly and conveniently connect the attachment 24 to the main body 3 without touching the attachment 24.

As shown by the dashed lines in Figures 21 and 25, the attachment 24 has a virtual axis 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 detached from the main body side connection port 27. The virtual axis X is, for example, an axis parallel to the intake direction or exhaust direction when the main body side connection port 27 and the attachment side connection port 47 are connected.

The virtual axis X, for example, coincides with the central axis of the attachment side connection port 47. For example, the virtual axis X is 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, if the connection port inner wall 47a is circular, the center is the same as the central axis. Also, for example, in the case of a rectangular shape, it is the intersection point of the midpoint in the longitudinal direction and the midpoint in the lateral direction. Also, in the case of a complex shape, it is the intersection point of a specific midpoint in the longitudinal direction and the midpoint in the direction perpendicular to the longitudinal direction. At least, the virtual axis X is located inside the connection port inner wall 47a of the attachment side connection port 47.

The support device 2 has a virtual axis Y. Preferably, the support 7 of the support device 2 has a virtual axis Y. The virtual axis Y extends, for example, in the vertical direction. The virtual axis Y is, for example, 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 varies depending on the shape of the cross section, but the cross section may be of any part as long as the centroid of the support 7 is inside the cross section of the support 7. The virtual axis Y of the support 7 is also in a similar position inside the connected holding body 8 (Figure 21).

The attachment outer shell 100 is the portion of the attachment 24 other than the attachment side connection port 47. When 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 portion 48, an attachment portion 49, and a support portion 52.

The air passage forming section 48 is a hollow member. The inside of the air passage forming section 48 functions as an internal air passage. The inside of the air passage forming section 48 is connected to the inner wall of the connection port 47a.

The mounting portion 49 is for mounting the attachment 24 to the support device 2. In this embodiment, the air passage forming portion 48 and the mounting portion 49 are located at a distance from each other. 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 mounting portion 49 is located at a position closer to the upper end than the lower end of the attachment 24. The mounting portion 49 protrudes in a direction away from the imaginary axis X. The mounting portion 49 is located at a position away from the imaginary axis X. The tip of the mounting portion 49, i.e., the position of the mounting portion 49 away from the imaginary axis X, extends in the direction of the imaginary axis X and in a direction perpendicular to the protruding direction of the mounting portion 49.

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

The attachment portion 49 has a large portion 50 and a small portion 51. The large portion 50 is a large and 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 a direction perpendicular to the insertion direction into the support device 2. The large portion 50 is positioned closer to the tip side than the small portion 51. For example, the large portion 50 is positioned farther from the attachment side connection port 47 than the small portion 51. For example, the large portion 50 is positioned farther from the virtual axis X than the small portion 51.

Next, the attachment 24 will be described using the aforementioned Fig. 21 and Figs. 27 to 30. 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 perspective view of the main parts of the blower nozzle 26 in the first embodiment from another direction.

As described above, the attachment 24 includes the bristle brush 25 and the blower nozzle 26. The bristle brush 25 includes the bristle brush side connection port 78, the bristle brush connection port inner wall 78a, the bristle brush air passage forming portion 79, the bristle brush attachment portion 80, and the bristle brush support portion 83. The blower nozzle 26 includes the nozzle side connection port 91, the nozzle connection port inner wall 91a, the nozzle air passage forming portion 92, the nozzle attachment portion 93, and the nozzle support portion 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 passage forming portion 79 and the nozzle air passage forming portion 92 are the air passage forming portion 48 of the attachment 24. The bristle brush attachment portion 80 and the nozzle attachment portion 93 are the attachment portion 49 of the attachment 24. The bristle brush support part 83 and the nozzle support part 96 are the support parts 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 includes, 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. They may also intersect with each other.

When the first plate 53 and the second plate 54 are viewed from the direction in which they protrude from the air passage forming section 48, the first plate 53 and the second plate 54, for example, intersect at right angles. For example, they intersect in a T-shape. For example, they intersect in a cross shape.

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

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

When viewed from the direction in which the small portion 51 and the third plate 56 protrude from the air passage forming portion 48, for example, they intersect at right angles. For example, they intersect in a T-shape. For example, they intersect in a cross shape.

As described above, the large part 50 and the small part 51 are supported by two or more plate-like members. In addition, the support part 52 itself is also made of two or more plate-like members that are in contact with each other. Therefore, the large part 50, the small part 51, and the support part 52 have a strength that makes them less likely to break even if force is applied during installation.

Next, the bristle brush 25 will be described with reference to FIGS.
The bristle brush 25 is a suction attachment. The bristle brush 25 utilizes suction air. The bristle brush 25 has 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 bundles 75 are arranged around the bristle brush suction port 84. The bristle bundles 75 are, for example, a plurality of bristle bundles 75. The bristle brush 25, for example, has a function as a brush, and rubs the surface to be cleaned and dust on the surface to be cleaned. In other words, it performs suction and sweeping at the same time. When the dust on the surface to be cleaned is rubbed, the adhesion force between the surface to be cleaned and the dust is reduced. This makes it easier for the dust to be sucked in.

The bristle brush 25 has 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 by inserting it into the suction port 28. 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 4. In other words, the latch 76 and spring 77 of the bristle brush 25 maintain the connection with the suction port 28 and the tube 4, and the 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. The bristle brush 25 connection port 78 has 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 a virtual 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, for example, the central axis of the bristle brush 25. 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 part 80 is disposed at a position closer to the bristle brush side connection port 78 than the bristle brush suction port 84. The bristle brush attachment part 80 is provided on the opposite side of the latch 76. In other words, when cleaning the surface to be cleaned, the bristle brush attachment part 80 is disposed at a position closer to the surface to be cleaned than the latch 76. Note that the position of the bristle brush attachment part 80 is not limited to this embodiment.

Next, the blower nozzle 26 will be described with reference to Figures 29 and 30. The blower nozzle 26 is a blower attachment. The blower nozzle 26 is an attachment 24 for blowing away dust from the surface to be cleaned using exhaust air. The blower nozzle 26 is hollow tubular. The blower nozzle 26 has an elongated shape.

The blower nozzle 26 has a nozzle side connection port 91 and a latch 89 at the upper end, and a blowing port 90 at the lower end. The nozzle side connection port 91 is the attachment side connection port 47. The nozzle side connection port 91 is connected by inserting it into the exhaust port 29. The blowing port 90 is for blowing the exhaust air that flows in from the nozzle side connection port 91 out of the main body 3. The blower nozzle 26 has a tapered shape from the nozzle side connection port 91 to the blowing port 90. The latch 89 maintains the connection between the exhaust port 29 and the nozzle side connection port 91, and allows the user to easily release this connection. The blower nozzle 26 has a nozzle attachment portion 93. The nozzle attachment portion 93 is for attaching the blower nozzle 26 to the support device 2. The nozzle attachment portion 93 is located closer to the nozzle side connection port 91 than the blowing port 90.

The blower nozzle 26 has an imaginary axis X2. The imaginary axis X2 is one of the imaginary axes X of the attachment. The imaginary axis X2 is, for example, the longitudinal axis of the blower nozzle 26. The imaginary axis X2 is, for example, an axis parallel to the attachment/detachment direction between the exhaust port 29 and the nozzle side connection port 91. The imaginary 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 imaginary axis X2 and the center of gravity are located inside the inner wall 47a of the connection port.

Next, the state where the attachment 24 is attached to the main body 3 will be described using Figures 31 to 33. Figure 31 is a side view showing the state where the bristle brush 25 is attached to the main body 3 in embodiment 1. Figure 32 is a side view showing the state where the blower nozzle 26 is attached to the main body 3 in embodiment 1. Figure 33 is a side view showing the state where the blower nozzle 26 is attached to and detached from the main body 3 in embodiment 1.

As shown in Figures 31 to 33, when the attachment 24 is attached to the main body 3, the mounting portion 49 is preferably located on the front or rear side. In other words, the mounting portion 49 is visible when viewed from the side in Figures 31 to 33 and when viewed from the side in the opposite direction to Figures 31 to 33. This provides excellent symmetry.

As shown in FIG. 31, the bristle brush 25 is connected to the suction port 28 of the main body 3 for use. When the bristle brush 25 is connected to the main body 3 to clean a horizontal surface, the main body 3 is in a position similar to that shown in FIG. 4. That is, the front of the main body 3 is positioned higher than the rear. In addition, the bristle brush attachment portion 80 is positioned on the rear side, and the latch 89 is positioned on the front side.

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

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 air outlet 90. The user can blow away dust and other particles by holding the handle 10 and pointing the air outlet 90 toward the surface to be cleaned.

As shown in FIG. 15 above, a shutter unit 30 is attached to the exhaust port 29. The shutter unit 30 is a plate-like member that has a lattice shape with multiple holes. The shutter unit 30 is attached so that it can open and close the exhaust port 29. One side of the shutter unit 30 is attached to the edge of the exhaust port 29 via a rotating shaft 31. The shutter unit 30 can move between a position where it closes the exhaust port 29 and a position where it rotates around the rotating shaft 31 toward the inside of the outer shell 9 to open the exhaust port 29.

The shutter section 30 adjusts the opening area of the exhaust port 29. When the shutter section 30 is in the open position, 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, air is exhausted through multiple holes. The total opening area of the multiple holes is smaller than the opening area when the shutter section 30 is open. For this reason, air resistance is large when the shutter section 30 is closed.

When attaching or detaching the blower nozzle 26 to or from the exhaust port 29, the blower nozzle 26 is inserted or 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 or detached from the exhaust port 29.

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

When the blower nozzle 26 is inserted into the exhaust port 29, the shutter section 30 is pushed by the blower nozzle 26 and rotates around the pivot 31 toward the inside of the outer shell section 9. When the blower nozzle 26 is attached to the exhaust port 29, the shutter section 30 opens the exhaust port 29, and the aforementioned exhaust air passage of the main body 3 and the inside of the blower nozzle 26 are completely connected.

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

Next, the mounting portion 57 of the support device 2 will be described with reference to Figures 34 and 35. Figure 34 is a side view of the main part of the holder 8 in embodiment 1. Figure 35 is a top view of the support device 2 in embodiment 1.

Figure 34 shows the top of the holding body 8. The support device 2 has a mounting portion 57 for the attachment 24. In this embodiment, the mounting portion 57 is provided on the holding body 8. The mounting portion 57 is provided, for example, on an extension of the support body 7. The mounting portion 57 is disposed at a higher position than the suction port 28 of the main body 3. The mounting portion 57 has an opening. The mounting portion 57 has an opening that resembles, for example, an upside-down inverted "convex" character. The plate thickness of the mounting portion 57 is thicker than the surrounding plate thickness. This increases the strength of the attachment 24 when it is attached to and detached from the support device 2. In addition, even if the edge of the mounting portion 57 is rounded, it does not become thin, and is excellent in terms of strength, prevention of cuts by the user, and prevention of damage to the mounting portion 49. The mounting portion 57 opens approximately perpendicular to the surface to be cleaned. Therefore, as shown in Figure 35, the opening of the mounting portion 57 cannot be seen from the top.

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

As shown in Figures 21 and 25, the attachment 24 is supported at an incline with respect to the support device 2. For example, the imaginary axis X of the attachment 24 is inclined with respect to the vertical direction. For example, the attachment 24 is supported at an incline with respect to the support device 2 so that the horizontal distance between the imaginary axis X of the attachment 24 and the support device 2 increases as it moves upward.

In addition, 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 it. 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 it. This makes it easier to connect the attachment 24 supported by the support device 2 by bringing the main body 3 close to the attachment 24 and connecting the attachment side connection port 47 and the main body side connection port 27, as the main body 3 is less likely to come into contact with the support device 2. Note that the imaginary axis X is inclined, for example, in the 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 positioned inside the outer periphery of the support device 2 when viewed from above. In other words, the attachment 24 cannot be seen when viewed from below. As a result, even when the attachment 24 is attached to the support device 2, the floor space required for installation does not increase.

Figure 34 shows the shape of the attachment portion 57. The attachment portion 57 is an opening made up of multiple shapes. For example, the opening of the attachment portion 57 is a rectangle of different sizes. The attachment portion 57 has an insertion position 58 and a restriction position 59. The larger rectangular shape of the attachment portion 57 is the insertion position 58, and the smaller rectangular shape is the restriction position 59. The insertion position 58 is an opening at a position that allows the attachment portion 49 of the attachment 24 to be inserted. In other words, the insertion position 58 is an opening at 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. In other words, when the attachment 24 is supported by the support device, the attachment 24 is located at the restriction position 59. The restriction position 59 is also a position that restricts the attachment 24 from moving in the horizontal direction.

The mounting portion 49 of the attachment 24 can be moved between an insertion position 58 and a restricting position 59 when inserted into the mounting portion 57. For example, the mounting portion 49 can be moved between the insertion position 58 and the restricting position 59 by moving in a direction perpendicular to the insertion direction. In this embodiment, the movement direction is the up-down direction. Furthermore, the insertion position 58 is located above the restricting position 59.

The attachment 24 remains supported by the support device 2. The lower side of the mounting portion 49 is supported by the mounting receiving portion 57. In other words, the attachment 24 is restricted from moving downward.

As described above, the large part 50 is larger than the small part 51. For example, when the attachment 24 is supported by the support device 2, the large part 50 is long and the small part 51 is small in the front-rear and vertical directions. In this embodiment, when the attachment 24 is supported by the support device 2, the large part 50 is long in the front-rear direction and the small part 51 is small. The large part 50 and the small part 51 are smaller than the insertion position 58. That is, the large part 50 and the small part 51 can be inserted into the insertion position 58. On the other hand, the restriction position 59 is smaller than the large part 50 and larger than the small part 51. That is, when the attachment 24 is supported by the support device 2, it cannot be inserted or removed in the horizontal direction. Therefore, when the mounting part 49 moves from the insertion position 58 to the restriction position 59, the movement of the attachment 24 in the horizontal direction is restricted. When the attachment 24 is inserted all the way, the attachment 24 can be moved in a predetermined direction with the attachment 24 inserted. The predetermined direction is, for example, downward.

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

Furthermore, if there were nothing to restrict the movement of the mounting portion 49, the attachment 24 would rotate from the contact point between the mounting portion 49 and the attached portion 57 as a starting point so that the center of gravity would be located below the contact point.
However, when the side surface of the attachment 24 comes into contact with the support device 2, the movement in the horizontal direction is restricted and the attachment 24 comes to a standstill. In this manner, the attachment 24 moves due to gravity so that the center of gravity is positioned below the contact position between the mounting portion 49 and the mounted portion 57. As a result, the attachment 24 tilts.

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

As described above, the attachment 24 is supported by the support device 2 through two movements, one in the insertion direction and one perpendicular to the insertion direction. However, the restriction position 59 is located below the insertion position 58. That is, if the user releases the attachment portion 49 after inserting it into the insertion position 58, gravity will move the attachment portion to the restriction position 59. That is, the user can cause the support device 2 to support the attachment 24 by only moving in one direction during insertion. In other words, the movement in one direction by the user's hand changes the direction in which insertion was possible to a direction in which movement is restricted.

The holder 8 includes a partition 60. The partition 60 is provided near the mounting portion 57. The partition 60 is disposed at the center of the support 7 from the opening of the mounting portion 57. The partition 60 prevents, for example, dust and foreign matter from entering the support 7 through the mounting opening. When the mounting portion 49 is inserted into the mounting portion 57 and when the mounting portion 49 is supported, the mounting portion 49 may come into contact with the partition 60.

Next, the support device 2 will be described with reference to Figures 36 and 37. Figure 36 is a longitudinal cross-sectional view of the main part of the base body 6 in embodiment 1. Figure 37 is a longitudinal cross-sectional view of the vacuum cleaner system in embodiment 1.

As shown in FIG. 36, the base 6 includes a control unit 62 and a sheet metal member 63. For example, the control unit 62 has a function of controlling the charging of the secondary battery of the battery unit 13, which is not shown in FIG. 36. For example, the control unit 62 has a function of converting external AC power into DC power.

The sheet metal member 63 functions as a weight. The sheet metal member 63 functions to prevent the spread of fire due to the combustion of the control unit 62. The sheet metal member 63 functions to protect the control unit 62. The sheet metal member 63 also functions to firmly fix the base 6 and the support 7. For example, the sheet metal member 63 is formed of a flame-retardant material. For example, the sheet metal member 63 has self-extinguishing properties, that is, it burns while exposed to a flame, but when it is removed from the flame, it is extinguished and the fire is unlikely to spread. For example, the sheet metal member 63 is a steel plate having a thickness of 1.6 mm or more. Preferably, the sheet metal member 63 is a steel plate having 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, for example, the upper part of the control unit 17.

As shown in FIG. 37, the support 7 is provided so as not to break when supporting a heavy object such as the main body 3. For example, at least a part of the exterior of the support 7 is formed of a material stronger than a resin material. For example, at least a part of the exterior of the support 7 is formed of a metal material. The metal material extends in the vertical direction. For example, the metal material extends from the lower end to the upper end of the support 7. For example, the metal material is firmly fixed to the sheet metal member 63.

Next, the holder 8 will be described using Figures 38 to 44. Figure 38 is a perspective view of the holder in embodiment 1. Figure 39 is a front view of the holder 8 in embodiment 1. Figure 40 is a longitudinal cross-sectional view of the main parts of the holder 8 in embodiment 1. Figure 41 is a perspective view of the main parts of the holder 8 in embodiment 1. Figure 42 is a longitudinal cross-sectional view of the main parts of the vacuum cleaner system in embodiment 1. Figure 43 is a cross-sectional view of the main parts taken along line I-I in Figure 42. Figure 44 is a cross-sectional view of the main parts taken along line N-N in Figure 42.

As shown in Figures 38 and 39, the holder 8 includes a holding case 64, a tube holder 65, a main body holder 66, and a release portion 67.

The holding case 64 is fixed to the upper part of the support 7, which is not shown in FIG. 39. A part of the holding case 64 is concave when viewed from above. A space exists in the concave part of the holding case 64. The space opens upward and downward. The space opens to the rear in a straight line from top to bottom.

The holding case 64 has inner walls 64a, 64b, and 64c (not shown). Inner walls 64a, 64b, and 64c form part of the concave shape of the holding case 64. Inner wall 64a is the inner wall at the back, located between inner walls 64b and 64c, among the inner walls forming the concave portion.

Although not shown, the retaining case 64 includes a plurality of shaft support portions. For example, each of the plurality of shaft support portions is a hole. For example, a portion of each of the plurality of shaft support portions is arc-shaped. For example, a portion of each of the plurality of shaft support portions is cut out.

The tube body holding part 65 is supported by the holding case 64. The tube body holding part 65 holds the vacuum cleaner 1, which is not shown in FIG. 39. For example, the tube body holding part 65 holds the vacuum cleaner 1 by sandwiching it from both sides. Specifically, the tube body holding part 65 holds the upper end part of the tube 4 by sandwiching it from both sides. The tube body holding part 65 may also sandwich the main body 3 from both sides.

The main body holding part 66 is supported by the holding case 64. The main body holding part 66 is positioned above the tube body holding part 65. The main body holding part 66 holds the main body 3. For example, the main body holding part 66 holds the connection tube part 14. Specifically, the main body holding part 66 holds the connection tube part 14 by sandwiching it from both sides. The main body holding part 66 may also hold a part of the main body 3 by sandwiching it. The main body holding part 66 can charge the main body 3.

The release portion 67 protrudes from the inner wall 64a of the holding case 64. For example, the upper end and lower end of the release portion 67 that are away from the inner wall 64a may be inclined. The lower end may protrude approximately perpendicularly from the inner wall 64a. In other words, only the upper end may be inclined. For example, the upper end and lower end of the release portion 67 that are away from the inner wall 64a are rounded. Although not shown in FIG. 39, the release portion 67 is positioned above the button portion 43a of the latch portion 38 or at the same height. The width of the release portion 67 is smaller than the width of the button portion 43a.

As shown in FIG. 41, for example, the tube holder 65 includes a left holder 68a, a right holder 68b, and a spring 69. For example, the left holder 68a and the right holder 68b are arranged to face each other. For example, the left holder 68a and the right holder 68b are arranged symmetrically.

The left side holding portion 68a has a left side shaft portion 70a. The left side shaft portion 70a is provided at the front of the left side holding portion 68a. The left side shaft portion 70a protrudes from the upper and lower ends of the left side holding portion 68a. The left side shaft portion 70a is rotatably supported by a shaft support portion of the holding case 64, which is not shown in FIG. 41. The rotation direction of the left side holding portion 68a at this time is perpendicular to the up-down direction of the vacuum cleaner system. The rotation direction is horizontal to the floor surface.

The right-side holding portion 68b includes a right-side shaft portion 70b. The right-side shaft portion 70b is provided at the front of the right-side holding portion 68b. The right-side shaft portion 70b protrudes from the upper and lower ends of the right-side holding portion 68b. The right-side shaft portion 70b is rotatably supported by a shaft support portion of the holding case 64, which is not shown in FIG. 41. The rotation direction of the right-side holding portion 68b at this time is perpendicular to the up-down direction of the vacuum cleaner system. The rotation direction is horizontal to the floor surface.

For example, the spring 69 is a tension spring. It is positioned rearward of the left shaft portion 70a and the right shaft portion 70b. The spring 69 is connected to the left holding portion 68a and the right holding portion 68b. The initial tension of the spring 69 pulls the left holding portion 68a and the right holding portion 68b toward each other. The spring 69 brings the left holding portion 68a and the right holding portion 68b closest to each other when no external force other than its own force is acting on the left holding portion 68a and the right holding portion 68b.

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

When viewed from above, a part of the left holding portion 71a and a part of the right holding portion 71b are formed in a triangular shape. The left holding portion 71a and the right holding portion 71b are disposed at the same height. The left holding portion 71a and the right holding portion 71b are disposed symmetrically.

The left side holding part 71a has a left side shaft part 73a. The left side shaft part 73a is provided at the front part of the left side holding part 71a. The left side shaft part 73a is cylindrical. The left side shaft part 73a protrudes from the upper end and the lower end of the left side holding part 71a. The left side shaft part 73a is rotatably supported by a shaft support part of the holding case 64, which is not shown in FIG. 41. In this case, the rotation direction of the left side holding part 71a is perpendicular to the vertical axis of the vacuum cleaner system. The rotation direction is horizontal to the floor surface.

The right side holding part 71b has a right side shaft part 73b. The right side shaft part 73b is provided at the front part of the right side holding part 71b. The right side shaft part 73b is cylindrical. The right side shaft part 73b protrudes from the upper end and the lower end of the right side holding part 71b. The right side shaft part 73b is rotatably supported by a shaft support part of the holding case 64, which is not shown in FIG. 41. In this case, the rotation direction of the right side holding part 71b is perpendicular to the vertical axis of the vacuum cleaner system. The rotation direction is horizontal to the floor surface.

For example, spring 72 is a tension spring. It is positioned rearward of left shaft portion 73a and right shaft portion 73b. Spring 72 is connected to left holding portion 71a and right holding portion 71b. Spring 72 draws left holding portion 71a and right holding portion 71b toward each other by initial tension. Spring 72 brings left holding portion 71a and right holding portion 71b closest to each other when no external force other than its own force is acting on left holding portion 71a and right holding portion 71b.

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

The left side support device charging terminal portion 74a and the right side support device charging terminal portion 74b are formed from triangular metal plates. The left side support device charging terminal portion 74a and the right side support device charging terminal portion 74b are formed so as to taper. The left side support device charging terminal portion 74a and the right side support device charging terminal portion 74b are formed so that the depth width becomes smaller as the left and right distance between them becomes closer. The left side support device charging terminal portion 74a and the right side support device charging terminal portion 74b are arranged at the same height. The left side support device charging terminal portion 74a and the right side support device charging terminal portion 74b are arranged symmetrically.

In FIG. 44, before the tube 4 comes into contact with the left retaining portion 68a and the right retaining portion 68b, the distance between the tip of the left retaining portion 68a and the tip of the right retaining portion 68b is shorter than the width of the latch portion 38. The distance between the tip of the left retaining portion 68a and the tip of the right retaining portion 68b is shorter than the distance between the left recess 44a and the right recess 44b.

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

When the latch portion 38 moves further so as to be pressed against the left holding portion 68a and the right holding portion 68b, the tip of the left holding portion 68a and the tip of the right holding portion 68b are stored in the left recess 44a and the right recess 44b, respectively. At this time, the left holding portion 68a and the right holding portion 68b are displaced in a direction narrowing the distance between them. As a result, the tube 4 is held by the holder 8 while being sandwiched between the left holding portion 68a and the right holding portion 68b.

When the tip of the left holding part 68a and the tip of the right holding part 68b are stored in the left recess 44a and the right recess 44b, respectively, the left holding part 68a and the right holding part 68b press against the left recess 44a and the right recess 44b by the force of the spring 69. The left holding part 68a and the right holding part 68b continue to press against the left recess 44a and the right recess 44b by the force of the spring 69 unless an external force other than the spring 69, such as an external force from the user, acts. As a result, the tube 4 faces up and down while being held by the holder 8.

When the pipe section 36 moves in a direction away from the holder 8, the left holding section 68a and the right holding section 68b are displaced in a direction that increases the distance between them. For example, when the pipe section 36 moves rearward, the left holding section 68a and the right holding section 68b are displaced in a direction that increases the distance between them. When the pipe section 36 comes off the left holding section 68a and the right holding section 68b, the left holding section 68a and the right holding section 68b are positioned in the closest position due to the force of the spring 69.

Although not shown in detail, when the tube 4 is held by the holder 8, the lower surface of the first left restricting portion 45a is positioned above the left retaining portion 68a. The lower surface of the first right restricting portion 45b is positioned above the right retaining portion 68b. The upper surface of the second left restricting portion 46a is positioned below the left retaining portion 68a. The upper surface of the second right restricting portion 46b is positioned below the right retaining portion 68b.

The pipe body 4 is supported by the left first restricting portion 45a and the right first restricting portion 45b contacting the left holding portion 68a and the right holding portion 68b, respectively. Preferably, the pipe body 4 is supported by the left first restricting portion 45a and the right first restricting portion 45b contacting the upper end of the left holding portion 68a and the upper end of the right holding portion 68b, respectively.

When the tube 4 moves upward while held by the holder 8, the left second restricting portion 46a and the right second restricting portion 46b come into contact with the left holding portion 68a and the right holding portion 68b, respectively. Preferably, the left second restricting portion 46a and the right second restricting portion 46b come into contact with the lower end of the left holding portion 68a and the lower end of the right holding portion 68b, respectively. As a result, the tube 4 is restricted from moving upward.

In addition, regardless of whether the suction tool 5 is connected to the pipe body 4, the left first restricting portion 45a and the right first restricting portion 45b are supported by the left holding portion 68a and the right holding portion 68b, respectively. As a result, the pipe 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 while connected to the tube 4 and main body 3, its downward movement is restricted by the main body 3 and the holder 8 (Figure 3). When the main body 3 is removed and the tube 4 and suction tool 5 are supported, its downward movement is restricted by the suction tool 5 and the base 6 (Figure 10). When only the tube 4 is supported by the support device 2, its downward movement is restricted by the tube 4 and the holder 8 (Figure 12).

When the main body 3 is removed from the support device 2, the distance between the left side support device charging terminal 74a and the right side support device charging terminal 74b is shorter than the distance between the left side main body 3 charging terminal 39L and the right side main body 3 charging terminal 39R. When the main body 3 approaches the support device 2, the left side main body 3 charging terminal 39L and the right side main body 3 charging terminal 39R come into contact with the left side support device charging terminal 74a and the right side support device charging terminal 74b, respectively. After that, when the left side main body 3 charging terminal 39L and the right side main body 3 charging terminal 39R move so as to be pressed against the left side support device charging terminal 74a and the right side support device charging terminal 74b, respectively, the left side support device charging terminal 74a and the right side support device charging terminal 74b are displaced in a direction in which the distance between them increases. At this time, the left side holding portion 71a and the right side holding portion 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 side main body 3 charging terminal portion 39L and the right side main body 3 charging terminal portion 39R so as to sandwich them. As a result, the main body 3 is stable 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 charging terminal portion 74a and the right side support device charging terminal portion 74b are positioned closest to each other by the force of the spring 72.

Note that a part of the left holding portion 71a and a part of the right holding portion 71b are triangular in top view. Furthermore, an inclined portion is formed at the upper part of the left holding portion 71a and the upper part of the right holding portion 71b. Therefore, whether the left side main body 3 side charging terminal portion 39L and the right side main body 3 side charging terminal portion 39R contact the left side holding portion 71a and the right side holding portion 71b from above or from behind, respectively, the distance between the left side holding portion 71a and the right side holding portion 71b increases. Furthermore, whether the main body 3 moves in the upward or backward direction, the main body 3 comes off the support device 2.

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

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

When the tube 4 moves further upward after the latch 42a is placed in the second position, the left second restricting portion 46a and the right second restricting portion 46b come into contact with the left holding portion 68a and the right holding portion 68b, respectively. As a result, the upward movement of the tube 4 is restricted. When the main body 3 moves further upward, the main body 3 comes off the tube 4.

When the main body 3 is brought closer to the support device 2 from above while the tube 4 is supported by the support device 2, the latch tip 43b comes into contact with the fitting portion 19 of the connecting tube portion 14. When the main body 3 is then brought even closer to the support device 2 from above, the main body 3 and the tube 4 are connected. The main body 3 and the support device 2 are further connected.

When attaching or detaching the tube body 4 and the holder 8, 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 above-described embodiment 1, the attachment 24 is supported by the support device 2. For example, the support device 2 supports the attachment outer 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 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 where the attachment side connection port 47 faces upward is not limited to only the state where it is open 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. For example, this includes a state in which the virtual axis X is tilted within a range of -45° to 45° from the vertical. 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 to the main body 3 without touching the attachment 24.

Furthermore, when supported by the support device 2, the mounting portion 49 is positioned closer to the upper end than to the lower end of the attachment 24. Furthermore, the mounting portion 49 is positioned closer to the attachment side connection port 47 than the bristle brush suction port 84 or the air outlet 90. As a result, when force is applied to the attachment side connection port 47, the mounting portion 49 is positioned closer, and due to the principle of leverage, the force is less likely to be applied to the mounting portion 49 or the attached portion 57. Therefore, the attachment 24 or the support device 2 are less likely to be damaged.

The attachment 24 also has a virtual axis X. The virtual axis X is, for example, an axis parallel to the attachment/detachment direction between the attachment side connection port 47 and the main body side connection port 27. 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 tilted relative to the vertical direction. The support device also has a virtual axis Y. The virtual axis Y is, for example, parallel to the vertical direction. The virtual axis Y is, for example, disposed inside the support 7. The attachment 24 is supported by the support device 2 at an incline so that the distance between the virtual axis X of the attachment 24 and the virtual axis Y of the support 7 of the support device 2 increases as it moves upward. For example, when the attachment 24 is supported by the support device 2 with the virtual axis X 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 attachment 24 falling over or both of them being damaged. For this reason, the user must move the main body 3 carefully. On the other hand, as described above, when the virtual axis X of the attachment 24 is inclined relative to the virtual axis Y of the support 7 of the support device 2, the distance between the main body 3 and the support device 2 increases compared to when the virtual axis X is parallel to the vertical direction. For this reason, the main body 3 is less likely to come into contact with the support device 2, and the user can easily connect the main body 3 to the attachment 24.

The attachment 24 is supported on the support device 2 at an incline so that the horizontal distance between the attachment side connection port 47 and the support device 2 is wider at the top than at the bottom of the attachment side connection port 47. Depending on the structure of the attachment 24, the distance from the support device 2 may be closer at the top than at the bottom. However, the distance from the support device 2 to the attachment side connection port 47 as a whole becomes wider as it moves upward. The attachment 24 is supported on the support device 2 at an incline so that the shortest horizontal distance 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 at the top than at the bottom of the attachment side connection port 47. As a result, when connecting the main body 3 to the attachment 24 supported by the support device 2, the main body 3 is less likely to come into contact with the support device 2. This makes it easy for the user to connect the main body 3 to the attachment 24.

In addition, when the attachment 24 is supported by the support device 2, the support device 2 is provided with a restricting means for restricting the horizontal and downward movement of the attachment 24. As a result, when a user connects the main body 3 to the attachment 24 supported by the support device 2, the attachment 24 does not move downward. Furthermore, the attachment 24 will not fall if a horizontal force is applied before the main body side connection port 27 and the attachment side connection port 47 are completely connected. This allows for smooth connection and is easy to use. Furthermore, the attachment 24 will not fall if a horizontal force is applied to the support device 2. This provides high stability.

In addition, when the attachment 24 is attached to the support device 2, the attachment 24 is positioned inside the outer periphery of the support device 2 when viewed from above. In other words, the attachment 24 cannot be seen when viewed from below. As a result, even when the attachment 24 is attached to the support device 2, the floor area required for installation does not increase. In addition, it is highly safe because the user is unlikely to accidentally touch the attachment 24. Furthermore, even if a strong downward force is applied when installing, the support device 2 will not tip over.

In addition, when the holder 8 holds the tube 4 in a state where the tube 4 is detached from the main body 3, the main body 3 moves downward, so that the main body 3 is supported by the support device 2 and the main body 3 is connected to the tube 4. In other words, when the tube 4 and the attachment 24 are supported by the support device 2 and the main body 3 is detached from the support device 2, the main body 3 can be alternatively connected to either the tube 4 or the attachment 24. As a result, for example, if a user cleans using the main body 3 and then connects to the attachment 24, the user can move to cleaning with the attachment 24 connected. Also, when connected to the tube 4, the user can move to cleaning with the tube 4 connected. Furthermore, when connected to the tube 4 and installed on the support device 2, the vacuum cleaner 1 is supported by the support device 2. In other words, the user can easily move to multiple actions without coming into contact with the attachment 24 or the tube 4. This makes it easy to use.

The attachment 24 also has a mounting portion 49 for mounting to the support device 2. The support device 2 has a mounting portion 57 into which at least a part of the mounting portion 49 is inserted. The mounting portion 57 is, for example, an opening. The mounting portion 49 is, for example, a protruding portion. Preferably, the opening of the mounting portion 57 is provided substantially perpendicular to the surface to be cleaned. The substantially perpendicular angle is, for example, in the range of 80 to 100°. Preferably, it is in the range of 85 to 95°. More preferably, it is in the range of 87 to 93°. The mounting portion 49 of the attachment 24 is inserted into the mounting portion 57 by moving the attachment 24 in the horizontal direction. This eliminates the need for the support device 2 to have a protruding structure in order to mount the attachment 24. This does not impair the appearance. In addition, the user or clothing is unlikely to accidentally touch the mounting portion 57, which is excellent in safety and the resistance to the support device 2 tipping over. The attachment 24 can be attached to the support device 2 by moving it horizontally and then moving it downward.

The support device 2 may also have a plurality of attachment receiving portions 57 to which the attachment 24 can be attached. In this case, the attachment 24 can be attached to any of the attachment receiving portions 57. Preferably, the plurality of attachment receiving portions 57 have similar shapes. More preferably, the plurality of attachment receiving portions 57 have equivalent shapes. This allows the user to place the attachment 24 in a position that is easy to use relative to the plurality of attachment receiving portions 57 of the support device 2, which is convenient for use. Also, a plurality of attachments 24 may be provided. In this case, each attachment 24 can be attached to any of the attachment receiving portions 57 of the support device 2. This allows the user to place the attachment 24 in a position that is easy to use relative to the plurality of attachment receiving portions 57 of the support device 2, which is convenient for use.

In addition, when the main body 3 is supported by the support device 2, the mounting portion 57 of the support device 2 is positioned higher than the suction port 28. In addition, when the attachment 24 and the main body 3 are supported by the support device 2, the attachment side connection port 47 is positioned higher than the suction port 28. The main body 3 may be supported by the support device 2 in a state where it is connected to the tube body 4. In addition, the tube body 4 may be positioned so that it extends vertically. For example, the bristle brush side connection port 78 is positioned higher than the suction port 28. Generally, the attachment 24 is positioned at a high position, making it easier for the user to pick it up. For example, if the attachment 24 is supported at a low position such as the base 6, it is necessary to squat down to pick it up. However, if it is at the above-mentioned height, it can be easily picked up. In addition, it is also easy to connect the main body 3 to the attachment 24 supported by the support device 2 while holding the handle 10. Furthermore, the height of the handle 10 when the suction port 28 is connected to the bristle brush side connection port 78 of the bristle brush 25 supported by the support device 2 is higher than the height of the handle 10 of the main body 3 supported by the support device 2. In other words, if the user can place the main body 3 on the support device 2 while standing, the user can also connect the main body 3 to the attachment 24 supported by the support device 2 while standing. This makes it easy to connect the main body 3 to the bristle brush 25, making it easy to use.

The mounting portion 57 has an opening into which the mounting portion 49 is inserted. The opening has an insertion position 58 into which the mounting portion 49 can be inserted, and a restriction position 59 in which horizontal movement is restricted when the mounting portion 49 is inserted into the mounting portion 57. When the mounting portion 57 is inserted into the mounting portion 49, the mounting portion 49 can move between the insertion position 58 and the restriction position 59 in a direction perpendicular to the insertion direction of the mounting portion 49 into the mounting portion 57. This makes mounting easy, and when the attachment 24 is supported by the support device 2, horizontal movement is restricted, resulting in a so-called locked state, and the attachment 24 is less likely to fall off. This makes it easy to use.

The mounting portion 49 has a large portion 50 and a small portion 51 that is smaller than the large portion 50. The small portion 51 is positioned closer to the air passage forming portion 48 than the large portion 50. The large portion 50 is positioned farther away from the imaginary axis X or the inner wall of the connection port 47a than the small portion 51. The large portion 50 and the small portion 51 are smaller than the opening at the restricting position 59. The large portion 50 is larger than the opening at the restricting position 59. This makes it difficult for the attachment 24 to fall off when the mounting portion 49 is positioned at the restricting position 59. This makes it easy to use.

In addition, when the bristle brush 25 is connected to the main body 3, the bristle brush attachment part 80 is positioned on the rear side of the main body 3. This makes it difficult for the bristle brush attachment part 80 to be visible when cleaning a surface to be cleaned, such as a floor or desk, and does not mar the appearance.

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

Furthermore, the multiple mounting parts 57 of the support device 2 are symmetrical. For example, the multiple mounting parts 57 are arranged in symmetrical positions when viewed from the top. Also, for example, the multiple mounting parts 57 are arranged in symmetrical positions when viewed from the front. Preferably, the multiple mounting parts 57 have the same shape. The multiple mounting parts 57 are, for example, two mounting parts 57. This does not impair the appearance.

In addition, when the main body 3 and the tube body 4 are connected and the tube body 4 is supported by the support device 2, the main body 3 may be moved upward to detach from both the support device 2 and the tube body 4. This also allows the user to detach the main body 3 from the tube body 4 without having to hold the tube body 4 by hand. The main body 3 can then be connected to the attachment 24 supported by the support device 2. In other words, the user can connect the main body 3 connected to the tube body 4 to the attachment 24 without having to grasp either the tube body 4 or the attachment 24. This makes it easy to use.

As described above, the air passage forming section 48 and the mounting section 49 are disposed at a distance from each other. A support section 52 is provided between the air passage forming section 48 and the mounting section 49. Preferably, the support section 52 protrudes from the air passage forming section 48. However, the support section 52 may protrude from a member attached to the air passage forming section 48. The mounting section 49 may also be provided on a protruding section protruding from the air passage forming section 48. The support section 52 supports the mounting section 49. The support section 52 is made of at least a plurality of plate-shaped members. The plurality of plate-shaped 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. As a result, the small section 51 is supported by two or more plate-shaped members. In addition, the support section 52 itself is made of two or more plate-shaped members that are in contact with each other. For this reason, the small section 51 and the support section 52 are less likely to be damaged even if force is applied during installation.

The small part 51 is made of one or more plate-like members. The small part 51 is supported by the support part 52. The small part 51 or the support part 52 has a third plate 56. The third plate 56 is a plate-like member. The large part 50 is supported by the small part 51 and the third plate 56. The small part 51 and the third plate 56 are at least in contact with each other. They may also intersect with each other. This allows the large part 50 to be supported by the small part 51 and the third plate 56. For this reason, the large part 50 is less likely to be damaged even if force is applied during installation.

The main body 3 may be supported by the support device 2. For example, the dust collecting unit 11 or the handle 10 may be supported by the support device 2. For example, the main body 3 may be held at the same height as the upper end of the dust collecting unit 11 or above the upper end. Also, for example, the main body 3 may be held above the lower end of the battery unit 13. Preferably, the bottom of the dust collecting unit 11 or the front of the handle 10 may be supported by the support device 2. If the front of the handle 10 has a bottom, the bottom may be supported. For example, the support part 52 may be provided at the rear or upper part of the support 7, and the main body 3 may be held by the support part 52. In other words, the support part 52 may be provided directly above the support 7 and hold the main body 3. This allows the stability of the vacuum cleaner system to be increased by supporting at least a part of the main body 3 in addition to the tube body 4. 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. In addition, by holding the vacuum cleaner 1 at a high position, the vacuum cleaner 1 is less likely to come off the support device 2. In addition, by gripping the upper side, heavy objects such as batteries are less likely to come off the support device 2. As a result, the vacuum cleaner system is easier to use.

The support device 2 may also support the bottom of the dust collection unit 11. For example, when the main body 3 and the tube 4 are connected to the support device 2, the dust collection unit 11 may be slightly floating from the holder 8. For example, when the main body 3 is disconnected from the tube 4, the support device 2 may support the area directly below the center of gravity of the main body 3. In other words, when the main body 3 is disconnected from the tube 4, the bottom of the dust collection unit 11 may be supported by the support device 2. It is preferably supported by the upper surface of the holder 8. However, it is not necessary to directly support the area directly below the center of gravity of the main body 3. For example, it is sufficient to support it on an arc, and the center of gravity in a top view may be inside the arc. For example, it is sufficient to support it at three or more points, and the center of gravity in a top view may be inside a square connecting the points. As a result, the center of gravity is located within the supported area, so it does not fall over. In addition, the stability of the main body 3 when installed on the support device 2 can be increased, making it easy to use.

The support device 2 holds the tube 4 in a state where the tube 4 is connected to the main body 3 and in a state where the tube 4 is released from the connection with the main body 3. Preferably, the holder 8 holds the tube 4. In this case, the holder 8 holds the tube 4 whether or not the suction tool 5 is connected to the tube 4. In other words, the support device 2 can support only the tube 4. Therefore, when the main body 3 is used in a state where it is released from the connection with the tube 4, the tube 4 can be maintained in a state where it is held by the support device 2. Also, 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 4 can be supported by the support device 2. As a result, no space other than the support device 2 is required for the placement of the tube 4, and there is no problem with the placement of the tube 4.

In addition, when 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 4 has a left second restricting portion 46a and a right second restricting portion 46b. In this case, the holder 8 holds the tube 4 with the attachment/detachment direction of the tube 4 being horizontal. When the main body 3 moves upward while the tube 4 and the main body 3 are connected, the left second restricting portion 46a and the right second restricting 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 4. Therefore, by changing the movement direction and removal direction of the main body 3, cleaning of only the main body 3 and cleaning with the main body 3 and the tube 4 connected can be selected.

In addition, when the tube 4 moves upward while being held by the holder 8, the holder 8 changes the position of the latch 42a of the tube 4, thereby releasing the connection between the tube 4 and the main body 3. If the tube 4 moves further upward, the upward movement of the tube 4 is restricted. In this case, even if 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 tube 4 connected can be selected.

The latch portion 38 may also be provided on the main body 3. The release portion 67 may be in a state where the button portion 43a is pressed when the tube 4 is placed on the support device 2. In other words, when the tube 4 is placed on the support device 2, the latch 42a may be in a state where it is arranged in the second position. In other words, even when the tube 4 connected to the main body 3 is supported by the support device 2, the latch 42a may be in a state where it is arranged in the second position. As a result, there is less friction and resistance when moving the main body 3 upward, making it easier for the main body 3 to come off from the tube 4, and making it even easier to remove.

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

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

In this embodiment, an example has been described in which the dust collection unit 11 has a cyclone separation device that performs centrifugal separation. However, the dust collection unit 11 is not limited to this method of dust separation and accumulation as long as it separates dust from dust-laden air and accumulates the separated dust. For example, dust and air may be separated by a filter without centrifugal separation. Also, a so-called paper bag type may be used.

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

The suction port 28 and the exhaust port 29 may have the same shape. 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, connecting a blower attachment to the suction port 28 is excellent for cleaning gaps. This expands versatility.

In this embodiment, the blower attachment is connected to the exhaust port 29, which is located at a different position from the suction port 28. That is, the suction air toward the electric blower is used at the suction port 28, and the exhaust air from the electric blower is used at the exhaust port 29. However, the air path may be switched so that the exhaust air from the electric blower is blown out from the suction port 28. For example, the main body 3 may have an air path switching structure. In this case, by connecting the 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. This makes it easy to use.

Also, the device may be provided with only either the suction attachment or the blower attachment. Also, the main body 3 may not be provided with the exhaust port 29 for connecting the blower attachment. Also, the support device 2 may support multiple suction attachments. Also, the support device 2 may support multiple blower attachments.

In the above-described embodiment, an example has been described in which the attachment portion 49 is inserted into the attachment receiving portion 57 and then moved downward, thereby restricting movement in the horizontal direction. However, the attachment method is not limited. For example, it may be moved upward or sideways. It may also be rotated after insertion. It may also be moved in multiple directions after insertion.

It may also be inserted at an angle into the opening of the attachment portion 57. For example, if it has a bent or curved shape such as the letter "L", "U", "S", or "K", it is easy to insert it at an angle. In this case, gravity makes it difficult to move horizontally at the same time as insertion, so it is less likely to fall off. Therefore, it is possible to restrict insertion and horizontal movement by moving in one direction, including insertion. This makes it easy to use.
