[the making use-case etc. of the 1st embodiment]
Operator's gripping handle cover 3, when starting button 22 (press and open button 22a), lamp is opened, and makes the current flowing of battery 6 on lamp, and makes current flowing on motor 29.By being energized to lamp 24, lamp 24 is lit.In addition, by being energized to motor 29, motor 29 makes fan 34 rotate by turning cylinder 30.When fan 34 rotates, air is discharged into the outside of radiation direction by each blade 38.Thus, by continuing this state, thus the air-flow (wind) of air as described below is created.
That is, attract air by air entry 13, then air is inhaled in dust pocket 10.Be drawn into the air of dust pocket 10 by suction filter 15.When by suction filter 15, the dust in air is trapped by filter 16 and front filter 19.
If suction filter 15 (filter 16 and front filter 19) is high efficiency particulate air filter, then inlet capacity also can be correspondingly lower.Namely; high efficiency particulate air filter is while improving the capture rate to particle dust; throughput also can correspondingly reduce, and such as, in HEPA filter (catcher/filter of the dust of the diameter 0.3 μm of trapping more than 99.95%), the pressure loss is about 2 ~ 10 times of common filter.When this high efficiency particulate air filter being applied to the suction filter 15 of the upstream side (suction side) being positioned at fan 34, because throughput reduces, the air capacity sucked reduces, and thus the inlet capacity of cleaner 1 reduces.
But because suction filter 15 is not high efficiency particulate air filter, even if therefore suction filter 15 is configured in upstream side, throughput (soakage) does not also reduce, and inlet capacity does not also reduce.
In addition; if suction filter 15 is high efficiency particulate air filter; then because high efficiency particulate air filter directly contacts the air sucked by air entry 13; therefore high efficiency particulate air filter also touches the larger dust of particle; thus the filtration mesh of high efficiency particulate air filter is easily plugged; structure for trapping the particle dust in high efficiency particulate air filter efficiently is easily damaged, and therefore the high life-span of catching filter can shorten.
But, because suction filter 15 is not high efficiency particulate air filter, even if therefore suction filter 15 is arranged on upstream side, also (structure for the larger dust of arrested particles caused) degree of injury and the minimizing in life-span without the need to too minding.
Except the air of dust enters fan guard 27 by inner air entry 35, be discharged into the outside of fan guard 27 by fan 34.
Be reflected to rear after the air being attracted to fan 34 touches the inwall of fan guard 27, be then directed to the internal vent ports 37 of motor fixed part 28.
The air arriving internal vent ports 37 enters into rear, by the inside (between the outer surface of motor 28 and the inner surface of motor shell 39) of motor shell 39, guides to the inside of motor cover 12 from deflection plate 40.
Because air is not directly blow to motor cover 12, therefore, it is possible to suppress the vibration due to uneven the caused motor cover 12 of air quantity.In addition, because the direction of air circulation is guided as towards rear by deflection plate 40, therefore air can successfully circulate, also can suppress noise generation.
Enter the air of motor cover 12 inside via high efficiency particulate air filter 42, can discharge from the exhaust outlet 52,52.. of exhaust oral area 50.
High efficiency particulate air filter 42 can trap the extremely small dust in exhaust efficiently.In addition, the direction due to air is vented oral area 50 and is adjusted to toward the outer side, and therefore air can successfully flow, and also can suppress the generation of noise.
Because high efficiency particulate air filter 42 is positioned at the downstream (exhaust side) of fan 34, the function of the suction air of fan 34 therefore directly can not be hindered.In addition, in order to the suction filter 15 making to be configured near upstream side can the larger dust of arrested particles, can only using the smaller dust of particle as trapping object, like this, the filtration mesh of high efficiency particulate air filter 42 is not easy to be plugged, and high efficiency particulate air filter 42 is not easy to sustain damage, result high efficiency particulate air filter 42 can durable.
