And control device 200 is measured the amount of dust of accumulating in the dust storage chamber portion 73 according to the light income of light-emitting diode D2, when this amount of dust reaches refuse cleaning line L1, with drive motor M2, ejects dust collecting part 70.
[operation]
Below, just the operation of the electric dust collector that constitutes as mentioned above is illustrated:
At first, as shown in Figure 2, collecting unit of dust 50 is contained in the collecting unit of dust chamber 22 of main body of dust collector 11, as shown in Figure 1, dust leg 12 is connected on the connector 11A place of main body of dust collector 11, and section port body 15 is connected with lever operated pipe 13 by prolonging pipe 14.
And, not shown attaching plug is connected with socket, it is luminous that then control device 200 will make light emitting diode D1.The infrared light that light emitting diode D1 is sent is accepted by light-emitting diode D2.
Press the switch 13b of the operating portion 13A of lever operated pipe 13, then electric blower 24 begins to drive.After this electric blower 24 drives, air is inhaled into from the suction opening 24A of electric blower 24, by connecting ventilating path portion 25, negative pressure is to the containing box 81 inner generation effects of collecting unit of dust 50, and then the separation chamber portion 54 generation effects by suction 56 pairs of disposal box portions 74 of ventilating path portion and dust separating part 52.And also by 57 pairs of dust legs 12 of guiding ventilating path pipe, prolongation pipe 14 and section port body 15 generation effects, air and dust are sucked into from section port body 15 this negative pressure simultaneously.
Dust that this is sucked into and air are sucked the into inhalation interface 57a of collecting unit of dust 50 by prolonging pipe 14 and dust leg 12.This dust that is sucked inhalation interface 57a into is imported in the portion that the separates chamber 54 of dust separating part 52 by guiding ventilating path pipe 57 with air, is in Fig. 6 this separation portion chamber 54 in counterclockwise and rotates.
And, by this rotation, dust and air rely on inertia separated, and air is by the screen pack NF1 (with reference to Fig. 5) of dust-separating appliance 55 and the screen pack NF2 (not shown) of opening 154B, and then by aspirating in the containing box 81 that ventilating path portion 56 is sucked filter house 80 into.
On the other hand, separated dust relies on inertia force to be imported into being communicated with in the case portion 72 of dust collecting part 70 by the importing opening 53A of separation chamber portion 54 simultaneously with the part air.Dust that this is imported into and air are sucked into dust storage chamber portion 73 by the communication path 71 that is communicated with case portion 72, and dust is accumulated in the dust storage chamber portion 73.
Be sucked the into air of dust storage chamber portion 73, the opening 170A by screen pack NF3 and cover plate 170 bottoms is sucked into suction ventilating path portion 56, and then is sucked in the containing box 81 of filter house 80 into.
The folded filter 104 of air by folded filtering bodies 100 that is sucked in the containing box into 81 is sucked the into connection ventilating path portion 25 of main body of dust collector 11, and then is sucked the into suction opening 24A of electric blower 24.
Being sucked into, the air of the suction opening 24A of electric blower 24 is discharged from by the exhaust outlet 20H from main body of dust collector shown in Figure 2 11 in the electric blower 24.
On the other hand, when dust constantly was accumulated in dust storage chamber portion 73, because dust constantly covers the infrared light of accepting by light-emitting diode D2, therefore, light-emitting diode D2 can only accept infrared light by spells.And when accumulating dusts to dust storage chamber portion 73 and reaching the level of refuse cleaning line L1, dust can cover infrared light always, and light-emitting diode D2 can't accept infrared light.
According to the dust throughput that this display part 17 shows, know whether the swept surface of sweeping is also very dirty, and promptly whether swept surface also is stained with dust.
And, the dust of the communication path 71 by dust collecting part 70 constantly is accumulated in the dust storage chamber portion 73, and when the dust of accumulating in this dust storage chamber portion 73 reached the level of refuse cleaning line L1, dust can cover infrared light always, therefore, light-emitting diode D2 can't accept infrared light.
When light-emitting diode D2 at official hour or exceed schedule time when not accepting infrared light continuously, the dust of accumulating in 200 judgement dust storage chambers of control device portion 73 has reached ormal weight, has promptly reached the level of refuse cleaning L1.That is to say that control device 200 is the amounts that whether reached regulation according to the amount of dust that is subjected to accumulate in the light measurement dust storage chamber portion 73 of light-emitting diode D2.Like this, owing to be to judge according to the light state that is subjected to of a light-emitting diode D2 whether the dust of accumulating in the amount of dust of the communication path 71 by dust collecting part 70 and the dust storage chamber portion 73 has reached the amount of regulation, so do not need to be provided with special-purpose separately light-emitting diode, therefore, can provide cheap electric dust collector.
And when the cut-out switch 13a of the 13A of push portion, then control device 200 stops the driving of electric blower 24, and only drives the motor M2 of ejecting mechanism 1000 at official hour.Rely on the driving of this motor M2, armed lever assembly 1302 is clockwise direction (in Figure 11) and rotates, and movable component 1301 rearward moves from position shown in Figure 12, and the lock pawl 1202 of armed lever 1201 is pressed backward.Like this, the application of force that armed lever 1201 will be resisted not shown spring is the clockwise direction rotation, and the lock pawl 1202 of armed lever 201 breaks away from from the fitting portion 72Ma of the 2nd reinforcement 72M of dust collecting part 70, and the locking of dust collecting container 410 is disengaged.
After this locking was disengaged, the movable plate 1102 in the guiding case 1101 as shown in figure 15, upwards pushed away the 1st reinforcement 72R with dust collecting container 410 along with the application of force of spring 1103 is moved upward.That is: as shown in figure 16, eject dust collecting container 410.After dust collecting container 410 ejects, the user just can know that dusts in the dust storage chamber portion 73 of dust collecting container 410 have accumulated the level of refuse cleaning line L1 (with reference to Fig. 7), can clear up the dust of accumulating in the dust storage chamber 73 rapidly, the thing that the dust of accumulating in the dust storage chamber portion 73 is overflowed prevents trouble before it happens.
When the amount of dust of accumulating in the dust storage chamber portion 73 reaches the level of refuse cleaning line L1 or thereafter, when the cut-out switch 13a of operating portion 13A is not pressed even surpassed the predefined time (stipulated time), control device 200 in the driving of forcing to stop electric blower 24 also, drive motor M2 ejects dust collecting container 410.
Therefore, even the cut-out switch 13a of operating portion 13A is not pressed, also the thing that the dust of accumulating in the dust storage chamber portion 73 can be overflowed prevents trouble before it happens.
But when the driving of electric blower 24 is stopped, motor M1 will be driven at certain hour.Rely on the driving of this motor M1, driven wheel Ga begins rotation, drives 100 rotations of folded filtering bodies.
The rotation of this folded filtering bodies 100, the tip of protuberance T (with reference to Fig. 2) at front wall portion 84 places of dust separation unit 400 is contacted with the pleated spine of folded filter 104, vibration is passed to folded filter 104, shake off the dust that adheres on this folded filter 104.
In the above-described embodiments, be to report the dust of accumulating in the dust storage chamber portion 73 and reached the level of refuse cleaning line L1 by ejecting dust collecting container 410, report mode but be not limited only to this kind, for example, and also can be by the buzzer of ringing, light indicator lamp etc. and report.
In addition, in above-mentioned example, be that the dust accumulated in the dust storage chamber portion 73 is reported when reaching the level of refuse cleaning line L1, but also a plurality of light-emitting diodes can be disposed up and down, measure the amount of dust of accumulating in the dust storage chamber 73, report according to its accumulation.In addition, in the foregoing description, electric dust collector utilizes the inertial separation dust, but is not limited only to this, type of can also the useful filter device catching or dust do not flow directly into dust storage chamber portion 73 by separation portion type.
