Mode for Carrying Out the Invention

[0009] In one or more embodiments, the dust collector may include a suction cylinder into which a dust collection hose is inserted, a suction unit that includes a motor and a blower fan that rotates by the rotational force generated by the motor and generates a suction force at the suction port of the suction cylinder, and a battery mounting portion on which a battery pack is mounted, and a head having the battery mounting portion, and a tank disposed below the head. In the vertical direction, at least a part of the battery pack may be disposed so as to overlap the suction port.

[0010] In the above configuration, in the vertical direction, at least a part of the battery pack mounted on the battery mounting portion overlaps the suction port of the suction cylinder, so that an increase in the size of the dust collector is suppressed. In the vertical direction, since the positions of at least a part of the battery pack and the position of the suction port are the same, a space for arranging other components different from the battery pack and the suction cylinder is secured in the dust collector. That is, interference between the battery pack, the suction cylinder, and other components is avoided. Therefore, an increase in the size of the dust collector is suppressed.

[0011] In one or more embodiments, the outer shape of the head may be long in the front-rear direction. In the front-rear direction, at least a part of the battery pack may be disposed so as to overlap the suction port.

[0012] In the above configuration, in the front-rear direction, at least a part of the battery pack mounted on the battery mounting portion overlaps the suction port of the suction cylinder, so that an increase in the size of the dust collector is suppressed. In the front-rear direction, since the positions of at least a part of the battery pack and the position of the suction port are the same, a space for arranging other components different from the battery pack and the suction cylinder is secured in the dust collector. That is, interference between the battery pack, the suction cylinder, and other components is avoided. Therefore, an increase in the size of the dust collector is suppressed.

[0013] In one or more embodiments, the outer shape of the head may be long in the front-rear direction. In the left-right direction, the motor may be disposed between the battery pack and the suction port.

[0014] In the above configuration, in the left-right direction, since the motor is disposed between the battery pack and the suction port, the weight balance of the dust collector in the left-right direction is improved. By improving the weight balance of the dust collector, the stability and transportability during use of the dust collector are improved. In the left-right direction, since the positions of the motor, the battery pack, and the suction port are different, a space for arranging other components different from the motor, the battery pack, and the suction cylinder is secured in the dust collector. That is, interference between the motor, the battery pack, and the suction cylinder and other components is avoided. Therefore, an increase in the size of the dust collector is suppressed.

[0015] In one or more embodiments, the outer shape of the head may be long in the front-rear direction. In the front-rear direction, the motor may be disposed so as not to overlap with the battery pack and the suction port.

[0016] In the above configuration, in the front-rear direction, since the motor, the battery pack, and the suction port are arranged separately, the weight balance of the dust collector in the front-rear direction is improved.

Since the motor is separated from the battery pack and the suction port, a space for arranging other components different from the motor, the battery pack, and the suction cylinder is secured in the dust collector. That is, interference between the motor, the battery pack, and the suction cylinder and other components is avoided. Therefore, an increase in the size of the dust collector is suppressed.

Each of the operation switches 12A and 12B is operated to control the motor 24. Operation switch 12A is operated to switch the motor 24 on and off. Operation switch 12B is operated to adjust the rotational speed of the motor 24. Each of the operation switches 12A and 12B is operated to rotate. An operation signal is generated when at least one of the operation switches 12A and 12B is operated by the user. The operation signal is transmitted to the controller 11. The controller 11 switches the motor 24 on and off based on the operation signal from operation switch 12A. The controller 11 adjusts the rotation speed of the motor 24 based on the operation signal from the operation switch 12B. By adjusting the rotation speed of the motor 24, the suction force generated at the suction port 19 is adjusted. When the rotation speed of the motor 24 is high, the suction force generated at the suction port 19 is high. When the rotation speed of the motor 24 is low, the suction force generated at the suction port 19 is low.

[0097] [Motor cover] Figure 9 is a perspective view from below showing the motor cover 50 according to the embodiment. Figure 10 is a longitudinal cross-sectional view showing the motor cover 50 according to the embodiment. Figure 10 corresponds to the cross-sectional view taken along the line CC in Figure 9. As shown in Figures 8, 9, and 10, the motor cover 50 has an inner cylinder portion 55 arranged around the motor housing 26 and an outer cylinder portion 56 arranged outside the inner cylinder portion 55 in the radial direction of the motor rotation axis AX. An air passage 52 is formed between the inner cylinder portion 55 and the outer cylinder portion 56. Air from the blower fan 25 and the cooling fan 44 flows into the passage 52 through an inlet 53 provided in a part of the inner cylinder portion 55, then flows through the passage 52 and is discharged from the exhaust port 51. The passage 52 is formed to surround the motor housing 26. The passage 52 is formed to substantially encircle the motor housing 26. Because the length of the passage 52 is long, the generation of noise caused by airflow is suppressed. As shown in Figure 8, a sound-absorbing member 54 is placed in the passage 52. The sound-absorbing member 54 is a porous material such as a sponge. The sound-absorbing member 54 effectively suppresses the generation of noise.

[0098] As shown in Figure 9, the ceiling surface 57 of the flow path 52 has multiple parts of different heights. The ceiling surface 57 includes at least a first part 57A of a first height and a second part 57B of a second height lower than the first height. The ceiling surface 57 may have at least three parts of different heights. The change in the height of the ceiling surface 57 changes the cross-sectional area of ​​the flow path 52. This change in the cross-sectional area of ​​the flow path 52 suppresses the generation of noise caused by airflow.

[0099] As shown in Figures 9 and 10, a flow straightening rib 58 is provided in the flow path 52 near the exhaust port 51. The flow straightening rib 58 protrudes downward from the ceiling surface 57 of the flow path 52. Multiple flow straightening ribs 59 are provided at the exhaust port 51. The flow straightening ribs 59 are rod-shaped with bent portions. The flow straightening ribs 58 straighten the airflow so that the air discharged from the exhaust port 51 flows horizontally. If the air discharged from the exhaust port 51 flows downward, dust present on the surface to be cleaned may be stirred up by the force of the air. The flow straightening ribs 58 suppress the stirring up of dust present on the surface to be cleaned.

[0100] [Dust collection bag and bracket] Figure 11 is an exploded longitudinal cross-sectional view showing a dust collector 1 according to an embodiment. Figure 11 is a longitudinal cross-sectional view through the flow path 20 of the suction pipe 17. As shown in Figure 11, a flow path member 30 is fixed to the lower surface of the tank cover 4. The flow path member 30 has an inlet pipe 31 connected to the suction pipe 17 and a flange 32 provided on the upper part of the inlet pipe 31. The inlet pipe 31 and the flange 32 are a single component. The flange 32 is fixed to the cover portion 16 of the tank cover 4 by screws. Air sucked in from the suction port 19 and flowing through the flow path 20 flows into the internal space of the tank 3 via the inlet pipe 31.

[0101] In this embodiment, a dust collection pack 60 can be attached to the inlet pipe 31. The dust collection pack 60 is placed in the internal space of the tank 3. The dust collection pack 60 is attached to at least a portion of the tank 3 via a stay 70. The dust collection pack 60 is positioned in front of the filter unit 8.

[0102] Figure 12 is a perspective view showing a stay support rib 3B according to an embodiment. The stay support rib 3B supports the stay 70. As shown in Figures 6 and 12, the stay support rib 3B is provided on the inner surface of the tank 3. In this embodiment, the stay support rib 3B is provided on the upper part of the left inner surface of the tank 3, which faces to the right. The stay support rib 3B protrudes to the right from the left inner surface of the tank 3. The stay support rib 3B is provided in front of the filter unit 8.

[0103] Two stay support ribs 3B are provided, spaced apart in the front-rear direction. The stay support ribs 3B are annular in shape. A notch 3C is provided at the left end of the stay support rib 3B. A hook portion 3D is provided on the left inner surface of the tank 3. The hook portion 3D is positioned between the pair of stay support ribs 3B. The hook portion 3D protrudes to the right from the left inner surface of the tank 3. The amount of protrusion of the hook portion 3D from the left inner surface of the tank 3 is less than the amount of protrusion of the stay support rib 3B.

[0104] Figure 13 is a perspective view showing a part of the stay 70 and dust collection bag 60 according to the embodiment. A projection is provided on the lower surface of the stay 70, which is inserted inside the stay support rib 3B. In addition, a resin spring portion 71 is provided at the left end of the stay 70, which is hooked onto the hook portion 3D.

[0105] The stay 70 has an insertion portion 72 into which the base plate 61 of the dust collection bag 60 is inserted. The base plate 61 inserted into the insertion portion 72 is held in place by a pair of spring portions 73 of the stay 70.

[0106] An inlet 62 is provided in the center of the base plate 61. The inlet 62 is connected to the inlet pipe 31. The stay 70 has an arc-shaped recess 74 that runs along the inlet 62.

[0107] [Stay holding mechanism] Figure 14 is a perspective view showing the lower surface of the tank cover 4 according to the embodiment. Figure 15 is an enlarged perspective view of a part of the lower surface of the tank cover 4 according to the embodiment. Figure 15 corresponds to an enlarged view of a part of Figure 14. As described above, the flow path member 30 is fixed to the lower surface of the cover portion 16 of the tank cover 4. The flow path member 30 has an inlet pipe 31 and a flange 32 provided on the upper part of the inlet pipe 31. The flange 32 is fixed to the cover portion 16 by screws 33.

[0108] The flow path member 30 has a stay holding mechanism 34 that holds the stay 70. The stay holding mechanism 34 is provided on the lower surface of the flange 32. When the dust collection bag 60 is not used, the stay 70 is held by the stay holding mechanism 34. The stay 70 is held by the stay holding mechanism 34 such that the inlet pipe 31 is positioned inside the recess 74.

[0109] Figure 16 is a perspective view showing a flow path member 30 according to an embodiment. The stay holding mechanism 34 has a pair of hook portions 35 provided on the front of the flange 32 and a hook portion 36 provided on the rear of the flange 32. The pair of hook portions 35 are arranged in the left-right direction. The hook portions 35 are inserted into the insertion portion 72 of the stay 70. The resin spring portion 71 is hooked onto the hook portion 36.

[0110] Figure 17 is a diagram illustrating how to attach the stay 70 to the stay holding mechanism 34 according to the embodiment. As shown in Figure 17, when attaching the stay 70 to the stay holding mechanism 34, the user moves the stay 70 from behind the hook portion 35 to the front so that the hook portion 35 is inserted into the insertion portion 72 of the stay 70. After the hook portion 35 is inserted into the insertion portion 72, the user brings the rear end of the stay 70 closer to the hook portion 36 so that the resin spring portion 71 is hooked onto the hook portion 36. With the hook portion 35 inserted into the insertion portion 72, the resin spring portion 71 is hooked onto the hook portion 36, thereby attaching the stay 70 to the stay holding mechanism 34.

[0111] [Operation] The user operates the operation switch 12A to drive the motor 24 for cleaning using the dust collector 1. When the motor 24 is driven, the blower fan 25 rotates. When the blower fan 25 rotates, suction force is generated at the suction port 19.

[0112] When dry cleaning is performed, air is drawn into the intake port 19 via the dust collection hose 6. The air drawn into the intake port 19 flows into the internal space of the tank 3 via the intake pipe 17 and the inlet pipe 31. At least a portion of the air that flows into the internal space of the tank 3 passes through the filter unit 8 and flows into the inner space of the filter unit 8. Dust contained in the air is collected by the filter unit 8. The air that flows into the inner space of the filter unit 8 flows into the internal space of the fan cover 27 via the intake port 28. The air that flows into the internal space of the fan cover 27 via the intake port 28 passes through the flow path 52 of the motor cover 50 and is then discharged from the exhaust port 51.

[0113] When wet cleaning is performed, liquid is drawn into the suction port 19 via the dust collection hose 6. The liquid drawn into the suction port 19 flows into the internal space of the tank 3 via the suction cylinder 17 and the inlet cylinder 31. At least a portion of the liquid that flows into the internal space of the tank 3 is stored in the tank 3. At least a portion of the liquid that flows into the internal space of the tank 3 passes through the filter unit 8 and flows into the internal space of the filter unit 8. A float 9 is located in the internal space of the filter unit 8. The float 9 can float on liquid. When liquid flows into the internal space of the filter unit 8, the float 9 moves upward to block the intake port 28 of the suction unit 7. By moving the float 9 to the intake port 28 of the suction unit 7 and blocking the intake port 28, the flow of liquid into the internal space of the fan cover 27 and the internal space of the motor housing 26 is suppressed. This prevents liquid from entering the motor 24.

[0114] [effect] As described above, in this embodiment, the dust collector 1 includes a head 2 having a suction cylinder 17 into which a dust collection hose 6 is inserted, a suction unit 7 including a motor 24 and a blower fan 25 that rotates due to the rotational force generated by the motor 24 to generate suction force at the suction port 19 of the suction cylinder 17, and a battery mounting section 10 into which a battery pack 29 is attached, and a tank 3 located below the head 2. In the vertical direction, at least a portion of the battery pack 29 is positioned to overlap the suction port 19.

[0115] In the above configuration, at least a portion of the battery pack 29 mounted on the battery mounting section 10 overlaps with the suction port 19 of the suction pipe 17 in the vertical direction, thus suppressing an increase in the size of the dust collector 1. In the vertical direction, the position of at least a portion of the battery pack 29 and the position of the suction port 19 are the same, so space is secured in the dust collector 1 to place other components besides the battery pack 29 and the suction pipe 17. In other words, interference between the battery pack 29 and the suction pipe 17 and other components is avoided. Therefore, an increase in the size of the dust collector 1 is suppressed.

[0116] In this embodiment, the head 2 is elongated in the front-to-back direction. In the front-to-back direction, at least a portion of the battery pack 29 is positioned to overlap with the suction port 19.

[0117] In the above configuration, at least a portion of the battery pack 29 mounted on the battery mounting section 10 overlaps with the suction port 19 of the suction pipe 17 in the front-to-back direction, thus suppressing an increase in the size of the dust collector 1. In the front-to-back direction, the position of at least a portion of the battery pack 29 and the position of the suction port 19 are the same, so space is secured in the dust collector 1 to place other components besides the battery pack 29 and the suction pipe 17. In other words, interference between the battery pack 29 and the suction pipe 17 and other components is avoided. Therefore, an increase in the size of the dust collector 1 is suppressed.

[0118] In this embodiment, the head 2 is elongated in the front-to-back direction. In the left-to-right direction, the motor 24 is positioned between the battery pack 29 and the suction port 19.

[0119] In the above configuration, the motor 24 is positioned between the battery pack 29 and the suction port 19 in the left-right direction, improving the weight balance of the dust collector 1 in the left-right direction. This improved weight balance of the dust collector 1 enhances its stability and portability during use. In the left-right direction, the positions of the motor 24, battery pack 29, and suction port 19 are different, providing space for other components in the dust collector 1 besides the motor 24, battery pack 29, and suction pipe 17. In other words, interference between the motor 24, battery pack 29, and suction pipe 17 and other components is avoided. Therefore, the size of the dust collector 1 is kept from increasing.

[0120] In this embodiment, the head 2 is elongated in the front-to-back direction. In the front-to-back direction, the motor 24 is positioned so as not to overlap with the battery pack 29 and the suction port 19.

[0121] In the above configuration, the motor 24, battery pack 29, and suction port 19 are positioned apart in the front-to-back direction, improving the weight balance of the dust collector 1 in the front-to-back direction. This improved weight balance of the dust collector 1 enhances its stability and portability during use. Because the motor 24 is positioned apart from the battery pack 29 and suction port 19, space is secured for other components in the dust collector 1 besides the motor 24, battery pack 29, and suction pipe 17. In other words, interference between the motor 24, battery pack 29, and suction pipe 17 and other components is avoided. Therefore, the size of the dust collector 1 is kept from increasing. Because the motor 24 is positioned apart from the suction port 19, dust sucked in from the suction port 19 is prevented from accumulating near the suction port 19. Therefore, a decrease in the dust collection capacity of the dust collector 1 is suppressed.

[0122] In this embodiment, the dust collector 1 includes an operating switch 12B that is operated for controlling the motor 24. In the vertical direction, at least a portion of the operating switch 12B is positioned to overlap with the battery pack 29 and the suction port 19, respectively.

[0123] In the above configuration, at least a portion of the operation switch 12B overlaps with the battery pack 29 and the suction port 19 in the vertical direction, thus suppressing the increase in size of the dust collector 1.

[0124] In this embodiment, the dust collector 1 includes a controller 11 that controls the motor 24. In the vertical direction, at least a portion of the controller 11 is positioned to overlap with the battery pack 29 and the suction port 19, respectively.

[0125] In the above configuration, at least a portion of the controller 11 overlaps with the battery pack 29 and the suction port 19 in the vertical direction, thus suppressing the increase in size of the dust collector 1.

[0126] In this embodiment, the dust collector 1 includes a controller 11 that controls the motor 24. In the front-to-back direction, at least a portion of the controller 11 is positioned to overlap with the battery pack 29 and the suction port 19, respectively.

[0127] In the above configuration, at least a portion of the controller 11 overlaps with the battery pack 29 and the suction port 19 in the front-to-back direction, thus suppressing the increase in size of the dust collector 1.

[0128] In this embodiment, the dust collector 1 includes operating switches 12A and 12B that are operated for the motor 24. In the left-right direction, operating switches 12A and 12B are located between the battery pack 29 and the suction port 19.

[0129] In the above configuration, the operation switches 12A and 12B are positioned between the battery pack 29 and the suction port 19 in the left-right direction, thus suppressing the increase in size of the dust collector 1.

[0130] In this embodiment, the dust collector 1 includes a controller 11 that controls the motor 24. In the left-right direction, the controller 11 is positioned between the battery pack 29 and the suction port 19.

[0131] In the above configuration, the controller 11 is positioned between the battery pack 29 and the suction port 19 in the left-right direction, thus suppressing the need to increase the size of the dust collector 1.
