DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In principle, identical elements are designated by the same reference numerals in all drawings. Furthermore, descriptions of parts having identical functions will be omitted. Note that the configurations described below are merely examples, and it is not intended that the embodiments of the present invention be limited to the specific embodiments below. [Example]

[0011] 1 is a perspective view of the appearance of a vacuum cleaner according to an embodiment of the present invention. In this embodiment, the front, back, left, and right directions are defined from the viewpoint from which a user operates the vacuum cleaner 100, and the direction toward the ceiling is defined as up, and the direction toward the surface to be cleaned is defined as down.

[0012] 1, electric vacuum cleaner 100 comprises vacuum cleaner body 101 equipped with electric blower 102 and dust collection unit 103 that collects dust collected by the suction force generated by electric blower 102, extension tube 300 having one end connected to vacuum cleaner body 101 and communicating with dust collection unit 103, and suction mouth body 200 connected to the other end of extension tube 300. Vacuum cleaner body 101 also comprises battery unit 104 as a driving source, grip unit 105, and switch unit 106 provided on grip unit 105 that turns electric blower 102 on and off.

[0013] When switch unit 106 is operated, electric blower 102 housed in vacuum cleaner body 101 starts operating, and a suction airflow is generated in suction body 200. The suction airflow sucks dust on the floor surface through suction body 200. The sucked dust passes through extension tube 300 and is collected in dust collection unit 103 of vacuum cleaner body 101.

[0014] The electric vacuum cleaner is not limited to the stick-type vacuum cleaner shown in the figure, but can also be applied to handheld vacuum cleaners, canister vacuum cleaners (cylinder vacuum cleaners), etc. The invention can also be applied to corded vacuum cleaners with a similar configuration.

[0015] Fig. 2 is an external perspective view of the suction body 200 according to the first embodiment of the present invention. Fig. 3 is a front view of the suction body 200 according to the first embodiment of the present invention, as seen from the front side. Fig. 4 is a cross-sectional view of the suction body 200 according to the first embodiment of the present invention, taken along the front-rear direction, in the standard mode. Fig. 5 is a cross-sectional view of the suction body 200 according to the first embodiment of the present invention, taken along the front-rear direction, in the wiping mode. In Fig. 4, the wiping member 208 is in a raised position, and in Fig. 5, the wiping member 208 is in a lowered position.

[0016] The suction mouth body 200 comprises a suction mouth body 201 that forms an outer shell and has a suction mouth 201a at the bottom, a connection joint 202 that is rotatably connected to the rear of the suction mouth body 201 and that guides dust sucked through the suction mouth 201a to the dust collection unit 103 via the extension tube 200, a rotary cleaning body 203 that is rotatably arranged facing the suction mouth 201a, an electric motor 205 that drives the rotary cleaning body 203 via a belt 204, an illumination means 206 that illuminates the surface F to be cleaned, and a rotatable rear wheel 207 that is arranged below the suction mouth body 201 and that travels on the surface F to be cleaned. The rotary cleaning body 203 is provided with a plurality of brush portions 203a along the axial direction.

[0017] Furthermore, the suction mouth unit 200 of this embodiment is provided with a wiping member 208 that is arranged below the suction mouth main body 201 and is capable of moving up and down, and a switching unit 209 that switches between raising and lowering the wiping member 208. The wiping member 208 comes into contact with the surface F to be cleaned, such as a floor, and performs the wiping cleaning.

[0018] Fig. 6 is an external perspective view of wiping member 208. Fig. 7 is a front view showing the connection state of wiping member 208 and switching unit 209 in standard mode. Fig. 8 is a front view showing the connection state of wiping member 208 and switching unit 209 in wiping mode. In Fig. 7, wiping member 208 is in a raised position, and in Fig. 8, wiping member 208 is in a lowered position.

[0019] Wiping member 208 is formed in an L-shape when viewed from the left and right, and includes cleaning section 208a facing surface F to be cleaned, sound insulating section 208b rising vertically from cleaning section 208a, brush 208c attached to the surface of cleaning section 208a facing surface F to be cleaned, and detachable mechanism 208d attached to the surface of cleaning section 208a facing suction mouth body 201 and detachably connecting to suction mouth body 201. Attachable mechanism 208d is formed of, for example, a permanent magnet, and wiping member 208 is attached to suction mouth body 201 by attracting this permanent magnet to a metal section provided on suction mouth body 201.

[0020] As shown in FIGS. 7 and 8, the wiping member 208 and the switching unit 209 are mechanically connected.

[0021] Switching part 209 is equipped with pressing part 209a that protrudes above suction mouth body 201, connecting part 209b that connects to wiping member 208, and guide part 209c that is provided on connecting part 209b and guides one end of connecting bar 210. Connection bar 210 connects lower case 201b of suction mouth body 201 and connecting part 209b of switching part 209, with one end connected to guide part 209c of connecting part 209b and the other end rotatably connected to hole 201b1 provided in lower case 201b of suction mouth body 201.

[0022] When switching portion 209 is not pressed, that is, when switching portion 209 is positioned above suction mouth body 201, one end of connecting bar 210 is positioned below guide portion 209c. In this state, wiping member 208 is in a position where it does not come into contact with surface F to be cleaned. When switching portion 209 is pressed, one end of connecting bar 210 moves so as to bypass guide portion 209c and is positioned above guide portion 209c. In this state, wiping member 208 is in a position where it comes into contact with surface F to be cleaned.

[0023] 5, when switching part 209 is pressed downward, wiping member 208 descends from suction mouth body 201 toward surface F to be cleaned, and brush 208c provided on cleaning part 208a comes into contact with surface F to be cleaned. Brush 208c then wipes surface F to be cleaned. When wiping member 208 descends from suction mouth body 201 toward surface F to be cleaned, sound insulating part 208b closes the rear of suction mouth 201a. This reduces noise generated by the high-speed rotation of rotating cleaning body 203, which will be described later.

[0024] When wiping by the brush 208c is completed and the switching part 209 is pulled upward, the cleaning part 208a of the wiping member 208 rises away from the surface F to be cleaned, and the contact between the brush 208c and the surface F to be cleaned is released (FIG. 4).

[0025] When wiping the surface F to be cleaned using the wiping member 208, the bristles 208c come into contact with the surface F to be cleaned, which increases the frictional resistance when the suction body 200 is operated back and forth, and the operating force increases. This increases the burden on the user during cleaning. Means for solving this problem will be described below.

[0026] Fig. 9 is a block diagram of the vacuum cleaner 100 according to the first embodiment of the present invention. Fig. 10 is a flowchart showing the operation of the vacuum cleaner according to the first embodiment of the present invention.

[0027] Cleaner body 101 of electric vacuum cleaner 100 is equipped with control unit 107 that controls electric vacuum cleaner 100. Control unit 107 receives operation commands from switch unit 106 and controls electric blower 102 that generates suction force, electric motor 205 that drives rotary cleaning body 203, etc. Control unit 107 also has at least two operation modes as control programs: a standard mode in which wiping member 208 is raised to rotate rotary cleaning body 203, and a wiping mode in which wiping member 208 is lowered to rotate rotary cleaning body 203.

[0028] When the user presses the power ON button of switch unit 106, control unit 107 receives an operation command from switch unit 106 and starts controlling vacuum cleaner 100 (step S400).

[0029] Next, the control unit 107 acquires operation information of the switching unit 209 (step S401), and determines whether the switching unit 209 has been operated (step S402).

[0030] If switching unit 209 is operated (YES in step S402), control unit 107 determines whether or not the mode has transitioned to a wiping mode in which the surface to be cleaned F is wiped (step S403). In the electric vacuum cleaner 100, there are cases in which operation is terminated in a wiping mode in which wiping is performed, and then operation is resumed. In step S403, it is determined whether the mode is switched from the wiping mode to the standard mode, or from the standard mode to the wiping mode.

[0031] When the wiping mode is entered (YES in step S403), that is, when the wiping mode is selected by switching unit 209, wiping member 208 is lowered (step S404). In this embodiment, switching unit 209 and wiping member 208 are mechanically connected, but, for example, switching unit 209 may be configured as a switch, and suction mouth body 201 may be provided with an actuator that raises and lowers wiping member 208, so that control unit 107 detects the switch operation of switching unit 209 and operates the actuator to raise and lower wiping member 208.

[0032] After the wiping member 208 descends, the control unit 107 controls the motor 205 to increase the rotation speed of the rotary cleaning body 203 (step S405). The vacuum cleaner of this embodiment has at least two modes: a standard mode and a wiping mode. The standard mode is a mode in which the rotary cleaning body 203 rotates at a predetermined rotation speed to scrape up and suck up dust on the surface F to be cleaned. On the other hand, the wiping mode is a mode in which the rotation speed of the rotary cleaning body 203 is rotated at a higher rotation speed than in the standard mode to scrape up dust on the surface F to be cleaned and also to wipe the surface F to be cleaned with the wiping member 208.

[0033] When the wiping mode is selected by the switching unit 209, the control unit 107 controls the electric motor 205 to rotate the rotary cleaning body 203 at a higher rotation speed than in the standard mode, thereby reducing the operating force required for wiping by utilizing the rotational force of the rotary cleaning body 203. That is, since the rotary cleaning body 203 rotates in a direction that moves the suction body 200 forward (counterclockwise when viewed from the left side of the suction body 200) as shown by the arrow in Fig. 5, the rotational force of the rotary cleaning body 203 acts as an assist force that moves the suction body 200 forward, thereby reducing the operating force required for wiping.

[0034] In step S403, if the mode is not to be switched to the wiping mode (NO in step S403), the wiping member 208 is raised (step S406). After the wiping member 208 is raised, the control unit 107 controls the electric motor 205 to reduce the rotation speed of the rotary cleaning body 203 (step S407).

[0035] After the rotation speed of the rotating cleaning body 203 increases (step S405) or decreases (step S407), the control unit 107 determines whether the user has pressed the power OFF button of the switch unit 106 (step S408), and if the power OFF button has been pressed (YES in step S408), the control unit 107 stops the vacuum cleaner 100 and terminates control (step S409).

[0036] In step S408, if the power OFF button has not been pressed (NO in step S408), control unit 107 continues the operation of electric vacuum cleaner 100 and executes the process from step S401 again.

[0037] Furthermore, in step S402, if the switching unit 209 has not been operated (NO in step S402), the control unit 107 executes the process of step S408.

[0038] When the rotary cleaning body 203 rotates at high speed, noise is generated. Therefore, in this embodiment, when the wiping member 208 descends from the suction port body 201 toward the surface to be cleaned F, the sound insulating part 208b closes the rear of the suction port 201a. This reduces the noise generated by the high-speed rotation of the rotary cleaning body 203.

[0039] As described above, according to this embodiment, when wiping with the wiping member 208, the rotation speed of the rotating cleaning body 203 is increased, so that the operating force required to move the suction body 200 can be reduced, thereby reducing the burden on the user. [Example]

[0040] Next, a second embodiment will be described with reference to Figs. 11 and 12. Fig. 11 is a schematic cross-sectional view of the suction body 200 in the standard mode according to the second embodiment of the present invention, taken along the front-rear direction. Fig. 12 is a schematic cross-sectional view of the suction body 200 in the wiping mode according to the second embodiment of the present invention, taken along the front-rear direction. In Fig. 11, the wiping member 208 and the rotary cleaning body 203 are in a raised position, and in Fig. 12, the wiping member 208 and the rotary cleaning body 203 are in a lowered position. In the second embodiment, components common to the first embodiment are designated by the same reference numerals, and detailed descriptions thereof will be omitted. In the second embodiment, the rotary cleaning body 203 is raised and lowered together with the wiping member 208.

[0041] 11 and 12, the suction mouth body 201 is provided with a switching part 209, a wiping member 208, and a link part 209d connected to the rotary cleaning body 203. In FIG.

[0042] Link portion 209d is made up of leg portion 209d1 that extends in the vertical direction and connects switching portion 209 and wiping member 208, and arm portion 209d2 that extends forward from leg portion 209d1 and is connected to rotary cleaning body 203 via rotation shaft 203d. Link portion 209d moves in the vertical direction.

[0043] 11, the wiping member 208 and the rotating cleaning body 203 are in a raised position, and the tip of the brush portion 203a of the rotating cleaning body 203 is in contact with the surface F to be cleaned while the rotating cleaning body 203 is rotating, and the wiping member 208 is in a position away from the surface F to be cleaned. Figure 11 shows the standard mode in which the rotating cleaning body 203 scrapes up dust on the surface F to be cleaned and performs cleaning.

[0044] As shown in FIG. 12, when switching unit 209 is operated from the standard mode and pressed downward, wiping member 208 is pressed via link portion 209d and comes into contact with surface F to be cleaned. In other words, operating switching unit 209 transitions from standard mode to wiping mode. Furthermore, rotation shaft 203d of rotary cleaning body 203 connected to link portion 209d moves downward, and while rotary cleaning body 203 is rotating, the tip of brush portion 203a is pressed against surface F to be cleaned so as to deform. In wiping mode, the amount of deformation of the tip of brush portion 203a is greater than in standard mode.

[0045] The brush portion 203a of the rotary cleaning body 203 is pressed strongly against the surface F to be cleaned, thereby increasing the forward propulsion force of the suction body 200 by the rotary cleaning body 203. As a result, according to this embodiment, the operating force required when wiping with the wiping member 208 can be reduced.

[0046] In this embodiment, the rotation speed of the rotating cleaning body 203 is not changed, but as in the first embodiment, the rotation speed of the rotating cleaning body 203 may be increased when the switching unit 209 is pressed downward.

[0047] [Modification] In the second embodiment, the switching unit 209, the wiping member 208, and the rotary cleaning body 203 are mechanically connected using the link unit 209d, but the wiping member 208 and the rotary cleaning body 203 may be raised and lowered using, for example, an actuator. In this case, the link unit 209d connects the wiping member 208 and the rotary cleaning body 203, and the switching unit 209 is a switch that raises and lowers the wiping member 208 and the rotary cleaning body 203. Then, based on operation information from the switching unit 209, the control unit 107 drives the actuator to raise and lower the wiping member 208 and the rotary cleaning body 203 via the link unit 209d.

[0048] FIG. 13 is a flowchart showing the operation of the electric vacuum cleaner according to the modified example of the second embodiment of the present invention.

[0049] When the user presses the power ON button of switch unit 106, control unit 107 receives an operation command from switch unit 106 and starts controlling vacuum cleaner 100 (step S500).

[0050] Next, the control unit 107 acquires operation information of the switching unit 209 (step S501), and determines whether the switching unit 209 has been operated (step S502).

[0051] If switching unit 209 is operated (YES in step S502), control unit 107 determines whether or not the mode has transitioned to a wiping mode in which the surface to be cleaned F is wiped (step S503). In the electric vacuum cleaner 100, there are cases in which operation is terminated in a wiping mode in which wiping is performed, and then operation is resumed. In step S503, it is determined whether the mode is switched from the wiping mode to the standard mode, or from the standard mode to the wiping mode.

[0052] When the mode has been changed to the wiping mode (YES in step S503), that is, when the wiping mode has been selected by the switching unit 209, the control unit 107 drives the actuator to lower the wiping member 208 (step S504).

[0053] After wiping member 208 has descended, control unit 107 drives the actuator to lower rotary cleaning body 203 (step S505).

[0054] In step S503, if the mode is not to be switched to the wiping mode (NO in step S503), the control unit 107 drives the actuator to raise the wiping member 208 (step S406). After the wiping member 208 has been raised, the control unit 107 drives the actuator to raise the rotary cleaning body 203 (step S507).

[0055] After the rotating cleaning body 203 descends (step S505) or after the rotating cleaning body 203 ascends (step S507), the control unit 107 determines whether the user has pressed the power OFF button of the switch unit 106 (step S508), and if the power OFF button has been pressed (YES in step S508), the control unit 107 stops the vacuum cleaner 100 and terminates control (step S509).

[0056] In step S508, if the power OFF button has not been pressed (NO in step S508), control unit 107 continues the operation of vacuum cleaner 100 and executes the process from step S501 again.

[0057] Furthermore, in step S502, if the switching unit 209 has not been operated (NO in step S502), the control unit 107 executes the process of step S508.

[0058] As described above, according to this embodiment, when wiping with the wiping member 208, the rotating cleaning body 203 is pressed strongly against the surface F to be cleaned, thereby increasing the propulsion force, thereby reducing the operating force required when wiping with the wiping member 208. [Example]

[0059] Next, Example 3 will be described with reference to Figures 14 and 15. Figures 14 and 15 are schematic perspective views of the exterior of a suction mouth body 200 according to Example 3 of the present invention, as seen from the right rear. Parts of the configuration, such as the connection joint 202, are omitted from Figures 14 and 15. In Figure 14, the wiping member 208 is in a raised position, and in Figure 15, the wiping member 208 is in a lowered position. In Example 3, configurations common to Examples 1 and 2 are given the same reference numerals, and detailed descriptions thereof will be omitted. In Example 3, the wiping member 208 is raised and lowered in conjunction with the rotation of the wheel 211.

[0060] 14 and 15, wheels 211 for traveling on the surface to be cleaned are provided on both the left and right sides of suction mouth body 201. Wheels 211 are rotatably supported on suction mouth body 201 by rotation shafts 211a. Furthermore, lifting mechanism 212 is rotatably connected to rotation shaft 211a of wheel 211. Lifting mechanism 212 rotates in conjunction with the rotation of wheel 211. Lifting mechanism 212 has a drive gear portion 212a formed with a plurality of concaves and convexes in its circumferential direction. A rotating cleaning body 203 is provided in front of wheel 211.

[0061] A rising portion 208e that rises vertically from the cleaning portion 208a is provided on the front side of the wiping member 208, and a driven gear portion 208e1 formed with a plurality of concave and convex portions in the vertical direction is formed on the rising portion 208e. The driven gear portion 208e1 faces the drive gear portion 212a, and the two are arranged to mesh with each other.

[0062] 14, when the suction body 200 is moved forward, the wheels 211 rotate in the direction of the arrow, and the lifting mechanism 212 also rotates in the same direction. Because the drive gear portion 212a of the lifting mechanism 212 meshes with the driven gear portion 208e1 of the rising portion 208e, the rising portion 208e moves downward. Then, as shown in FIG. 15, the wiping member 208 descends and comes into contact with the surface F to be cleaned.

[0063] Next, as shown in Fig. 15, when the suction body 200 is moved backward, the wheels 211 rotate in the direction of the arrow, and the lifting mechanism 212 also rotates in the same direction. Because the drive gear portion 212a of the lifting mechanism 212 meshes with the driven gear portion 208e1 of the rising portion 208e, the rising portion 208e moves upward. Then, as shown in Fig. 14, the wiping member 208 rises and moves away from the surface F to be cleaned.

[0064] According to this embodiment, the wiping member 208 comes into contact with the surface to be cleaned F when the suction body 200 is moved forward, so that the surface to be cleaned F can be wiped clean, and the wiping member 208 is moved away from the surface to be cleaned F when the suction body 200 is moved backward, so that the operating force required when moving the suction body 200 backward can be reduced.

[0065] If wheel 211 continues to rotate, drive gear portion 212a of lifting mechanism 212 also continues to rotate, and wiping member 208, which is raised and lowered by driven gear portion 208e1, may continue to be pressed against surface to be cleaned F or toward suction mouth body 201. Therefore, it is advisable to provide a clutch mechanism between wheel 211 and lifting mechanism 212 to prevent lifting mechanism 212 from rotating more than necessary. [Example]

[0066] Next, Example 4 will be described using Figure 16. Figure 16 is an external perspective view of suction mouth body 200 according to Example 4 of the present invention, seen from the left rear. Configurations common to Examples 1 to 3 are given the same reference numerals, and detailed descriptions thereof will be omitted. In Example 4, wiping member 208 is formed in a flat plate shape and is detachably connected to suction mouth body 201 by attachment / detachment mechanism 208d.

[0067] Disposable paper sheets are sometimes used when wiping the surface to be cleaned F.
