Motor cover

FIG. 9 is a perspective view from below illustrating the motor cover 50 according to the embodiment. FIG. 10 is a longitudinal cross-sectional view illustrating the motor cover 50 according to the embodiment. FIG. 10 corresponds to a cross-sectional view taken along line C-C in FIG. 9. As illustrated in FIGS. 8, 9, and 10, the motor cover 50 includes an inner cylindrical part 55 disposed around the motor housing 26 and an outer cylindrical part 56 disposed outside the inner cylindrical part 55 in a radial direction of the motor rotation axis AX. An air channel 52 is formed between the inner cylindrical part 55 and the outer cylindrical part 56. The air from the blower fan 25 and the air from the cooling fan 44 flow into the channel 52 via an inlet 53 provided at a portion of the inner cylindrical part 55, flow through the channel 52, and then are discharged from the air outlet 51. The channel 52 is formed so as to surround the motor housing 26. The channel 52 is formed to substantially encircle the motor housing 26. Because a length of the channel 52 is long, generation of noise due to flow of air is reduced. As illustrated in FIG. 8, a sound-absorbing member 54 is disposed in the channel 52.

The ceiling surface 57 includes at least a first portion 57A having a first height and a second portion 57B having a second height lower than the first height. Note that at least three portions having different heights may be provided on the ceiling surface 57. The different heights of the ceiling surface 57 varies the cross-sectional area of the channel 52. The variation in the cross-sectional area of the channel 52 reduces the generation of noise due to flow of air.

As illustrated in FIGS. 9 and 10, a straightening rib 58 is provided in the channel 52 near the air outlet 51. The straightening rib 58 protrudes downward from the ceiling surface 57 of the channel 52. A plurality of flow straightening ribs 59 is provided on the air outlet 51.

After the hooks 35 are inserted into the insertion portions 72, the user brings a rear end of the stay 70 close to the hook 36 so that the resin spring 71 is hooked on the hook 36. When the resin spring 71 is hooked on the hook 36 with the hooks 35 inserted into the insertion portion 72, the stay 70 is attached to the stay holding mechanism 34.

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.

When dry cleaning is performed, air is sucked into the suction port 19 via the dust collection hose 6. The air sucked into the suction port 19 flows into the internal space of the tank 3 via the suction cylinder 17 and the inflow cylinder 31. At least a portion of the air flowing 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. Dust contained in the air is collected by the filter unit 8. The air flowing into the internal space of the filter unit 8 flows into the internal space of the fan cover 27 via the air inlet 28. The air flowing into the internal space of the fan cover 27 via the air inlet 28 passes through the channel 52 of the motor cover 50 and then is discharged from the air outlet 51.

When wet cleaning is performed, liquid is sucked into the suction port 19 via the dust collection hose 6. The liquid sucked into the suction port 19 flows into the internal space of the tank 3 via the suction cylinder 17 and the inflow cylinder 31. At least a portion of the liquid flowing into the internal space of the tank 3 is stored in the tank 3. At least a portion of the liquid flowing 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. The float 9 is disposed in the internal space of the filter unit 8. The float 9 can float on the liquid. When the liquid flows into the internal space of the filter unit 8, the float 9 moves upward so as to close the air inlet 28 of the suction unit 7. The float 9 moves to the air inlet 28 of the suction unit 7 and closes the air inlet 28, thereby preventing liquid from flowing into the internal space of the fan cover 27 and the internal space of the motor housing 26. This prevents liquid from entering the motor 24.
