The specific embodiment

Below, specify embodiment of the present invention with reference to accompanying drawing.

Fig. 1 is the right view of main body of dust collector 2 of the electric dust collector 1 of an embodiment of the present invention.In following explanation about electric dust collector 1 and component parts thereof, short of special instruction is is then recorded and narrated for ease, is that front side, right side are that rear side, inboard are that left side, front side are that the right side describes with the left side among Fig. 1.Need to prove that left and right directions is identical with width.

With reference to Fig. 1, electric dust collector 1 possesses main body of dust collector 2, flexible pipe 3, pipe portion (not shown), suction fitting (not shown).

Main body of dust collector 2 is the front and back box shapes of long band fillet slightly.In Fig. 1, illustrated as the framework 4 of the ducted body of the exterior contour that becomes main body of dust collector 2, the rearward end of face is installed in the left and right sides of framework 4 wheel 5, be installed in framework 4 the bottom surface leading section steamboat 6, be installed in the handle 7 of the end face of framework 4.

Rotate on floor X through wheel 5 and steamboat 6, main body of dust collector 2 can move on floor X swimmingly.The state of the main body of dust collector 2 when wheel 5 and steamboat 6 are contacted with floor X is called common state (non-receiving state).

Handle 7 is for bloating into circular-arc U word shape to rear side under overlooking, it can be that fulcrum ground rotates with the leading section.Handle 7 can rotate between the dump position (with reference to Fig. 1) of framework 4 end faces and the end face set-up positions (not shown) that roughly mode of quadrature erects with respect to framework 4.

The internal structure of main body of dust collector 2 (framework 4) next, is described.

Fig. 2 is the right side cross-sectional view of main body of dust collector 2.

With reference to Fig. 2, main body of dust collector 2 mainly possesses first filter 8, electric blower 9, second filter 10 in framework 4.

At this, on framework 4, on front surface 11, be formed with air entry 12, on 13 (sides), surface, back, be formed with exhaust outlet 14, go out the air flow circuit 15 that is communicated with air entry 12 and exhaust outlet 14 in framework 4 internal separation.Above-mentioned first filter 8, electric blower 9 and second filter 10 are configured in the air flow circuit 15.Particularly, first filter 8, electric blower 9 and second filter 10 when the air-flow direction from air flow circuit 15 (with reference to the thick arrow of black) is observed from the arranged in order of upstream side with first filter, 8 → electric blower, 9 → the second filters 10.

When main body of dust collector 2 was in common state, back surperficial 13 of framework 4 was extended in an approximate vertical direction.Exhaust outlet 14 is provided with a plurality of (are four at this) at the above-below direction substantial middle place on surface, back 13.These exhaust outlets 14 are at slit-shaped elongated on the width (Fig. 3 that states after the reference simultaneously), and are arranged above and below across the interval of regulation.

In addition, with the exhaust outlet 14A that is positioned at below explicitly, on the part of the formation exhaust outlet 14A on surface, back 13, be formed with recess 17 to the front side depression.When width is observed, the general triangular shape of recess 17 for attenuating, its elongated on width (simultaneously with reference to Fig. 3) towards the front side.Exhaust outlet 14A becomes the part of the preceding downside of recess 17, its from recess 17 backward the surface 13 expose and towards the back upside.

Be provided with the tabular shutter 18 that on width, is elongated at exhaust outlet 14A.The axle (not shown) that shutter 18 extends with broad ways through its leading section is that the center rotation opens and closes freely.Shutter 18 cuts out with the mode of downside extension backward, from the inboard inaccessible exhaust outlet 14 (not shown) of framework 4.On the other hand, look to the right from closing state when shutter 18 and to observe when counterclockwise rotating ormal weight down, it is opened with the mode of extending to front upper side, thus open row gas port 14A (with reference to Fig. 2).Outside the cleaning time, shutter 18 cuts out.

Flexible pipe 3 is for having the flexible pipe of flexible accordion-like, and the one of which end is connected with air entry 12, thereby the inside of flexible pipe 3 and air flow circuit 15 are interconnected.

In electric dust collector 1, an end of pipe portion (not shown) is connected with the other end of flexible pipe 3, and suction fitting (not shown) is connected with the other end of pipe portion.Suction fitting (not shown) is long flat up and down case shape on width, its bottom surface be formed with from above with the opposed suction inlet of floor X (not shown).

For this electric dust collector 1, when floor X was cleaned, electric blower 9 received driven by power and produces attraction.This attraction force acts is in the suction inlet (not shown) of suction fitting (not shown).Therefore; Under the effect of this attraction; Dust on the floor X is drawn in the suction fitting (not shown) by suction inlet (not shown), and is being drawn into the air flow circuit 15 of main body of dust collector 2 from suction inlet 12 through suction fitting, pipe portion (not shown), flexible pipe 3 backs successively.In addition, the dust of suction fitting (not shown) ambient air on floor X is inhaled in the air flow circuit 15.

Shown in the thick arrow of black, the air and the dust that are inhaled in the air flow circuit 15 are at first accepted by first filter 8.At this moment, dust is caught by first filter 8, and air separates with dust, continues in air flow circuit 15, to flow thereby have only air to pass through first filter 8.Air through first filter 8 is in the downstream of the electric blower on above-mentioned air-flow direction 9 ejection in air flow circuit 15 under the effect of electric blower 9.

Air (exhaust) to the ejection of the downstream of electric blower 9 passes through second filter 10.Second filter 10 has the high dust that belongs to so-called HEPA filter (HEPA (High Efficiency Particulate Air Filter)) or ulpa filter (ultralow penetrance air cleaner (Ultra Low Penetration Air Filter)) kind and catches performance, and it more can catch tiny dust than first filter 8.Therefore, when passing through second filter 10 from the exhaust of electric blower 9, being caught by second filter 10 in this exhaust by the most trickle dust of first filter, 8 seizure, thus, exhaust is through second filter 10 and by purification fully.

Continue in air flow circuit 15, to flow and towards back surperficial 13 sides of framework 4 through the exhaust behind second filter 10.

Then, arrive than be positioned at the exhaust outlet 14A of below lean on upside exhaust outlet 14 exhaust from than be positioned at exhaust outlet 14 that the exhaust outlet 14A of below leans on upside along general horizontal direction towards the rear to device external discharge (with reference to the thick arrow of dotted line).

On the other hand, arrive shutter 18 towards being positioned at the exhaust of the exhaust outlet 14A of below (with reference to the thick arrow of white).Thus, the shutter 18 of up to the present cutting out presses off under the effect of the blast of the exhaust that arrives shutter 18 (the thick arrow with reference to white), goes up tilt backward thereby turn to.Thus, exhaust outlet 14A upside backward is open, and the exhaust that kind shown in the thick arrow of white that arrives shutter 18 is discharged to device external from exhaust outlet 14A to top (particularly being the back upside).

So, from the exhaust outlet 14A that the is positioned at below upside air (with reference to the thick arrow of white) that the is discharged to device external air (with reference to the thick arrow of dotted line) of discharging to device external approximate horizontal ground from the exhaust outlet 14 that leans on upside than exhaust outlet 14A backward from side collision down.Thus, the air that rearward flows out from discharging by the exhaust outlet 14 of upside than exhaust outlet 14A is corrected for and flows to upwards, and shown in the thick arrow of white, it integrally goes up side flow backward.

The situation that this exhaust is discharged to device external from exhaust outlet 14 with the mode that flows to the top is called as the top exhaust.In addition, from exhaust outlet 14A backward the upside exhaust that is discharged to device external be called as air curtain (air curtain).

Owing to carry out the top exhaust from air flow circuit 15 interior air of discharging, so can prevent causing the dust on the floor X to fly upward on the floor X because of this air blows to water to device external.

In addition; When stopping the driving of electric blower 9 when the cleaning that finishes floor X; Because electric blower 9 no longer produces attraction, so air is no longer mobile in air flow circuit 15, thereby the air that shutter 18 is not pressed off (blast dies down); Shutter 18 cuts out because of its deadweight, thus inaccessible once more exhaust outlet 14A (not shown).Thus, when need not, can prevent that outside refuse from getting in the framework 4 from exhaust outlet 14A from exhaust outlet 14A ejection air.

Then, the electrolysis water smoke generation unit 20 that is built in electrolysis water smoke in this main body of dust collector 2, that state after generating is described.

With reference to Fig. 7, ultrasonic oscillator unit 32 comprises ultrasonic oscillator 39, is used for ultrasonic oscillator 39 is installed to the supporting member 40 on the casing 42.

Ultrasonic oscillator 39 is for having the metal thin discoideus piezoelectrics (with reference to Fig. 8 (b)) of leading flank 39A (side side) and trailing flank 39B (the opposing party's side).The diameter of ultrasonic oscillator 39 at this for example is about 14mm.On ultrasonic oscillator 39, be formed with a plurality of through holes 41.At this, each through hole 41 small one-tenth has the degree of the diameter below the 10 μ m.Need to prove, in Fig. 7,, represent through hole 41 bigger and lack than reality than actual for the ease of explanation.

With reference to Fig. 8 (b), supporting member 40 comprises first annular component 42, second annular component 43, the 3rd annular component 44 and Fourth Ring shape member 45.

First annular component 44 and second annular component 43 are size ring-type about equally.The part that on first annular component 42, marks off hollow space forms the roughly taper seat towards the rear side chap, as guide surface 46.Attitude with Fig. 8 (b) is a benchmark, and on first annular component 42, front part (right portions of Fig. 8 (b)) is stretched out and as flange part 42A to radial outside than rear section.

First annular component 42 overlaps hollow space separately consistent each other with second annular component 43.Under this state, first annular component 42 is arranged in rear side (Fig. 8 (b) is the left side) with respect to second annular component 43.Ultrasonic oscillator 39 is by first annular component 42 and 43 clampings of second annular component that are under the overlap condition.Under this state, in ultrasonic oscillator 39, trailing flank 39B exposes to rear side from the hollow space of first annular component 42, and leading flank 39A exposes to the front side from the hollow space of second annular component 43.

The 3rd annular component 44 and Fourth Ring shape member 45 are size ring-type about equally, and maximum inner diameter separately is bigger slightly than the external diameter of first annular component 42 and second annular component 43.In addition, be benchmark with the attitude of Fig. 8 (b), the rear end of the 3rd annular component 44 is along the inboard bending of complete cycle geocentric vertical and as holding section 44A.The internal diameter of Fourth Ring shape member 45 is minimum at rear side, and the internal diameter here is slightly littler than the internal diameter of second annular component 43.Pipe 47 (the supply roads) that suct of tubulose are connected with Fourth Ring shape member 45 from the front side.Attitude with Fig. 8 (b) is a benchmark, sucts pipe 47 downside extension forward with being wire.An end (upper end) 47A that sucts pipe 47 is as the base end part that sucts pipe 47, and its hollow space with the front side of the minimum of internal diameter in the shape member 45 of Fourth Ring links to each other, and the other end (bottom) 47B becomes the free end that sucts pipe 47.Sucting pipe 47 is the part of Fourth Ring shape member 45.

The 3rd annular component 44 overlaps hollow space separately consistent each other with Fourth Ring shape member 45.Under this state, the 3rd annular component 44 is positioned at rear side with respect to Fourth Ring shape member 45, and the 3rd annular component 44 and Fourth Ring shape member 45 are with first annular component 42 and second annular component 43 clampings of overlapping state with clamping ultrasonic oscillator 39.Under this state, the holding section 44A of the 3rd annular component 44 engages from the flange part 42A of rear side with first annular component 42, and first annular component 42 and second annular component 43 are compressed to Fourth Ring shape member 45.In addition, the internal communication of an end 47A who sucts pipe 47 of the hollow space of second annular component 43 and Fourth Ring shape member 45, an end 47A is connected with the leading flank 39A of ultrasonic oscillator 39 via the hollow space of second annular component 43.

This ultrasonic oscillator unit 32 is fixed on the casing 28 from the through hole 38 that back upside passes the bellying 36 of casing 28 through the pipe 47 that sucts of Fourth Ring shape member 45.In addition, through with screw 103 ultrasonic oscillator unit 32 being assembled on the bellying 36, ultrasonic oscillator unit 32 also can be fixed on (Figure 18 (a) that states after the reference) on the casing 28.Thus, ultrasonic oscillator 39 is installed on the casing 28.

When main body of dust collector 2 is in common state, be fixed in ultrasonic oscillator unit 32 under the state of casing 28 (with reference to Fig. 8 (a)), suct pipe 47 through hole 38 linearly shape extension of downside forward from the bellying 36 of casing 28 tank house 34 in.At this moment, be positioned near the leading section of bottom of tank house 34, do not contact with the internal face of casing 28 though suct pipe the other end 47B of 47.In addition, under this state, in ultrasonic oscillator unit 32, Fourth Ring shape member 45 contacts from the rear wall 36A of rear side with the bellying 36 of casing 28, and ultrasonic oscillator 39 extends to front upper side along rear wall 36A.Therefore, ultrasonic oscillator 39 (leading flank 39A and trailing flank 39B) is inclined to about above-mentioned 15 ° with respect to vertical direction.

In addition, in the ultrasonic oscillator 39 of this state, leading flank 39A is via the hollow space of second annular component 43 and suct pipe 47 and be communicated with the inside (tank house 34) of casing 28.On the other hand, trailing flank 39B is via the hollow space of first annular component 42 outside towards the back upside.

Splicing ear 33 (with reference to Figure 22) is contained in wiring closet 35 (with reference to Fig. 7), and exposes downwards from opening 28B (with reference to Fig. 7).Splicing ear 33 is electrically connected with two electrodes 30, level sensor 31 (with reference to Figure 18 (b)) and ultrasonic oscillator 39 via lead-in wire 48 (with reference to Figure 22).

In above such generation unit 20, at first,, pull down cap body 29 with from water supply hole 37 water filling in the tank house 34 of casing 28 with reference to Fig. 7.The water that injects from water supply hole 37 because of be positioned at water supply hole 37 under the inclined plane 28A of casing 28 collide and be directed to the left side, thereby spread all over to the zone in the left side of tank house 34 apace.In addition,, water and inclined plane 28A in tank house 34, spread all over circulation in tank house 34 thereby colliding.Thus, can prevent that foreign matter is attached to the medial surface of casing 28.

If with cap body 29 inaccessible water supply holes 37, then in tank house 34, water accumulates the water level of regulation behind the water that injects ormal weight.To accumulating in the water surface label symbol T of the water in the tank house 34.When water accumulated the water level of regulation in tank house 34, in tank house 34, the lower portion separately of two electrodes 30 was not had (need to prove, for stating behind the level sensor 31) by water logging.In addition, the other end 47B that sucts pipe 47 of ultrasonic oscillator unit 32 also is immersed in the water in the casing 42.On the other hand, the position of end 27A above water surface T of ingress pipe 27 is connected with casing 28, ingress pipe 27 with in tank house 34, lean on than water surface T above spatial communication.

At this, in generation unit 20, can guarantee sealing through using seal etc.The water that therefore, tank house 34 can not take place is to wiring closet 35 leaks, water leaks from the joint of each member of formation of the joint of the rear wall 36A of casing 28 and ultrasonic oscillator unit 32 or ultrasonic oscillator unit 32 situation (while is with reference to Fig. 8 (b)).

Next, as shown in Figure 6, from the top generation unit 20 is installed on the framework 4 of the main body of dust collector 2 that is in common state, accommodate the reception room 21 from the top.Be installed to 4 last times of framework fully at generation unit 20, splicing ear 33 is connected (with reference to Figure 22) with body terminal 49 on being located at framework 4.In addition, the connecting piece 26 that extends from motor cover body 25 is connected (with reference to Figure 22) from downside with the other end 27B of the ingress pipe 27 of generation unit 20, and thus, casing 28 combines (with reference to Fig. 5) via connecting piece 26 with motor cover body 25 interior electric blowers 9.

Then, during inaccessible reception room 21 (with reference to Fig. 3), as shown in Figure 2 when closing cover body 22, generation unit 20 is covered from the outside by cover body 22, thereby becomes the state that is built in main body of dust collector 2.Under this state, shown in Fig. 8 (a), the ejiction opening 23 of cover body 22 is opposed from the hollow space of first annular component 42 of back upside and ultrasonic oscillator unit 32.Thus, the trailing flank 39B of ultrasonic oscillator 39 via ejiction opening 23 from framework 4 (main body of dust collector 2) back surperficial 13 backward upside expose.At this moment, ultrasonic oscillator 39 also extends to front upper side, and tilts above-mentioned about 15 ° with respect to vertical direction.

Under this state, as above-mentioned, floor X is cleaned.At this moment, from the main body power supply (not shown) that is built in main body of dust collector 2 via above-mentioned body terminal 49 and splicing ear 33 (with reference to Figure 22) to generation unit 20 supply capabilities.

At this, with reference to Fig. 8 (b), in generation unit 20, as above-mentioned, the pair of electrodes 30 in the tank house 34 immerses in the water, through applying voltage via 48 pairs of pair of electrodes 30 of lead-in wire, can make the water in the tank house 34 become brine electrolysis by electrolysis.

More specifically, apply electrode off and on via 48 pairs of a pair of electrolysis 30 of lead-in wire, thereby alternately flow through predetermined electric current so that become opposite polarity each other, the water in the tank house 34 is by electrolysis thus.Water is generally running water, owing to contain chlorine in the running water, produces following electrochemical reaction through electrolysis.

(anode-side)

4H ₂O-4e ^-→4H ⁺+O ₂↑+2H ₂O

2Cl ^-→Cl ₂+2e ^-

(cathode side)

4H ₂O+4e ^-→2H ₂↑+4OH ^-

(between electrode)

H ⁺+OH ^-→H ₂O

Through above-mentioned electrochemical reaction, can generate and contain band bacteria-eliminating efficacy and the hypochlorous acid (HClO) of deodorizing effect and the brine electrolysis of active oxygen, and lodge in the inside of tank house 34.That is, the running water in the tank house 34 becomes the brine electrolysis of normal concentration through electrochemical reaction.

Then; In the process that floor is cleaned; If by the special switch 50 (being called mist switch 50 (beginning operating portion), the Figure 31 that states after the reference) that is pressed on the main body of dust collector 2, under the driven state of electric blower 9 (with reference to Fig. 2); Ultrasonic oscillator 39 is applied potential pulse, and ultrasonic oscillator 39 vibrates thus.

Thus, with reference to Fig. 5, the part of the air (exhaust) that in motor cover body 25, sprays through electric blower 9 shown in thick-line arrow that kind successively through connecting piece 26 and ingress pipe 27.Then, this exhaust that kind as shown in Figure 7 flows into the inside of the tank house 34 of casing 28 from the top.Like this, for casing 28, the part of the exhaust of electric blower 9 can get into inner tank house 34 (with reference to Fig. 5) through connecting piece 26 and ingress pipe 27.

Then, the water surface T of the brine electrolysis of tank house 34 is pushed in the exhaust that flow into the inside of (entering into) tank house 34 from the top from the top.Thus, the brine electrolysis of tank house 34 flow into to suct in the pipe 47 and in sucting pipe 47 from the other end 47B that sucts pipe 47 and rises.With reference to Fig. 8 (b), the brine electrolysis that in sucting pipe 47, rises arrives the leading flank 39A of (supplying to) ultrasonic oscillator 39 through the hollow space of second annular component 43 from an end 47A who sucts pipe 47.Like this, suct under the pipe 47 common states (non-receiving state) water of casing 28 (tank house 34) is supplied with to ultrasonic oscillator 39 at main body of dust collector 2.

At this moment; Under through the effect that applies the ultrasonic oscillator 39 that potential pulse vibrates; Near the through hole 41 (with reference to Fig. 7) of the leading flank 39A side of ultrasonic oscillator 39 brine electrolysis is by ultrasonic vibration, thus electrolysis water smoke (being designated hereinafter simply as " the mist ") M (with reference to Fig. 8 (a)) that produces as small water particle by through hole 41.And; Under the pressure of the exhaust of the inside that flow into tank house 34; The brine electrolysis of tank house 34 constantly supplies to ultrasonic oscillator 39; Thereby the mist by ultrasonic oscillator 39 produces sprays from through hole 41 under the pressure of exhaust, and passes through hollow space upside (oblique upper) ejection (with reference to Fig. 8 (a)) backward of first annular component 42.

As shown in Figure 2, by the mist M of ejiction opening 41 ejection from ejiction opening 23 ejections of cover body 22 and backward upside scatter.Need to prove, be corrected its emission direction to mist M through the guide surface 46 of first annular component 42 and the guide surface 24 of ejiction opening 23, thereby upside (oblique upper) sprays correctly backward with back upside different directions ejection.

Backward the mist M that scatters of upside after rising to the upper limit, under the effect of deadweight, be specifically parabolic shape ground backward downside descend.At this moment, mist M is lifted from the below by the air (with reference to the white of Fig. 2 arrow slightly) that as above-mentioned, carries out the top exhaust from the exhaust outlet 14 of main body of dust collector 2, so taking advantage of this air once more backward upside scatter, thereby spread all over each indoor corner.Thus, not only can remove at indoor floating virus and allergin the interior space is carried out degerming, but also can carry out deodorizing to indoor through mist M through mist M.

At this, as above-mentioned, the part of the exhaust of electric blower 9 is through the inside (with reference to Fig. 5) of connecting piece 26 entering casings 28, and under the pressure of this exhaust, the brine electrolysis in the casing 28 are fed into ultrasonic oscillator 39.Then, ultrasonic oscillator 39 is produced mist M by the brine electrolysis that is supplied to, and mist M is sprayed from through hole 41 (with reference to Fig. 7).That is, for this electric dust collector 1, the easy structure of the pressure of exhaust that can be through utilizing electric blower 9 makes the material (mist M) that purifies air discharge to device external.

Figure 10 is the right side view of the rear section of main body of dust collector 2, and it illustrates a part that comprises generation unit 20 with section.

With reference to Figure 10, generation unit 20 and framework 4 back surperficial 13 on the part that marks off reception room 21 between, spread all over the whole gapped Y (guideway) that guarantees regionally.Gap Y is divided into L word shape by generation unit 20 with in back surperficial 13 the part that marks off reception room 21 of framework 4 when width is observed.Then, under cover body 22 pent states, the leading section in the upper end of cover body 22 is formed with inlet 51, this inlet 51 along up/down perforation cover body 22 and from the top communication gap Y.In addition, the bottom of cover body 22 and framework 4 back surperficial 13 between or originally be formed with the outlet 52 of the communication gap Y from the rear on one's body in the bottom of cover body 22.Outlet 52 is the exhaust outlet 14 in abutting connection with surface, back 13 from upside.

In this case, if air carries out top exhaust (with reference to the thick arrow of white) from exhaust outlet 14, then the air in the Y of gap is to be flowed out from exporting 52 by the mode of above-mentioned air drawing.So, follow in this, produce from enter the mouth 51 through gap Y from exporting the 52 air streams (with reference to black arrow) that flow out.That is, the air of device external is at inlet 51 entering gap Y, this gap Y in outlet 52 with this air to the exhaust of discharging (with reference to the thick arrow of white) guiding from exhaust outlet 14.

In generation unit 20, owing to tank house 34 in, flow into exhaust, carry out electrolysis, so the temperature of the interior brine electrolysis of casing 28 (tank house 34) rises easily through electrode 30 (with reference to Fig. 2) from electric blower 9.Therefore, possibly cause the hypochlorous generation of the brine electrolysis in the tank house 34 or bacteria-eliminating efficacy and the deodorizing effect decline that concentration reduces and make brine electrolysis.

Therefore, utilize from exhaust outlet 14 by the guide effect of the air of top exhaust, produce from enter the mouth 51 through gap Y from exporting the air-flow of 52 air that flow out, can be utilized in gap Y flow air cooling generation unit 20 (casing 28) thus.Therefore, even cause the water temperature rise in the casing 28, also can be prevented the water temperature rise in the casing 28 by this air stream cooling through casing 28 because utilize electrode 30 to carry out electrolysis etc.

Figure 11 illustrates the state after main body of dust collector 2 erects corresponding to Fig. 8.

In addition, when the cleaning to floor X finished afterwards to take in electric dust collector 1, if main body of dust collector 2 is erected, then main body of dust collector 2 can change attitude, becomes receiving state shown in Figure 11 from above-mentioned common state (with reference to Fig. 8).In the main body of dust collector that is in receiving state 2, back surperficial 13 opposed from top and floor X (with reference to Figure 11 (a)) of framework 4.Thus, electric dust collector can be taken in compactly.

As above-mentioned; Under common state; For sucting pipe 47, because ultrasonic oscillator 39 supplies of the other end 47B side direction one end 47A of water from the water that immerses casing 28, so can utilize ultrasonic oscillator 39 to make electrolysis water smoke M discharge (with reference to Fig. 8).

On the other hand, under the state shown in Figure 11 (a), the trailing flank 39B that exposes from back surperficial 13 of main body of dust collector 2 via ejiction opening 23 of ultrasonic oscillator 39 is with respect to inclined and opposed from top and floor X.Therefore, the brine electrolysis that is envisioned that the tank house 34 of casing 28 is trickled down on floor X along trailing flank (among Figure 11, being downside) 39B (along the inclination of trailing flank 39B) from the through hole 41 (with reference to Fig. 7) of ultrasonic oscillator 39.

Yet; In this case; For through with the brine electrolysis of tank house 34 sucting for the pipe 47 to ultrasonic oscillator 39 guiding; Though the other end 47B is positioned under the water surface T of brine electrolysis of tank house 34 (with reference to Fig. 8) under common state, under receiving state its to above leaving water face T and not being immersed in the brine electrolysis of casing 28.Therefore, under receiving state, the brine electrolysis of tank house 34 can not guided (supply) to ultrasonic oscillator 39 through sucting pipe 47, thereby the brine electrolysis that can prevent casing 28 is unrestrained to floor X from the through hole 41 of ultrasonic oscillator 39.

Like this; The other end 47B is arranged under the water surface T of brine electrolysis of tank house 34 and is immersed in the water of casing 28 under common state; But under receiving state the other end 47B to above leaving water face T; This be because, suct pipe 47 from an end 47A towards the other end 47B and extending obliquely to the direction of separating from back surperficial 13 of framework 4.

Figure 12 is the figure that in Figure 11 (b), has been suitable for variation.

In order to reach same action effect, shown in figure 12, in advance the other end 47B is got final product to back surperficial 13 the direction of leaving framework 4 (under state usually is the front side, is upside under receiving state) bending to suct mode that pipe 47 becomes L word shape.So; Under common state; The other end 47B is arranged under the water surface T of brine electrolysis of tank house 34 and is immersed in the water (not shown) of casing 28; Can be thereby suct pipe 47 with brine electrolysis to ultrasonic oscillator 39 guiding, and the other end 47B under the receiving state shown in Figure 12 to above leaving water face T, so brine electrolysis can be unrestrained to floor X from ultrasonic oscillator 39 through sucting pipe 47.

Figure 13 (a) illustrates the section when cutting off generation unit 20 along the vertically extending tabular surface of direction up and down, and Figure 13 (b) is that the A-A of Figure 13 (a) is to looking cutaway view.Need to prove, be shown in phantom line ultrasonic oscillator 39 among Figure 13 (a).

Generation unit 20 shown in Figure 13 (b) is different with above-mentioned embodiment, and Fourth Ring shape member 45 (with reference to Fig. 8) are omitted.In this case, the rear wall 36A clamping of the bellying 36 of the 3rd annular component 44 and casing 28 is with first annular component 42 and second annular component 43 of overlapping state with ultrasonic oscillator 39 clampings.In addition, the through hole 38 of rear wall 36A connects rear wall 36A along the thickness direction of rear wall 36A, and is communicated with the hollow space of second annular component 43 from the front side.In addition, the partition wall 53 that extends through approximate horizontal ground of the tank house 34 of the inside of casing 28 marks off than the inside part of bellying 36 and leans on the part (generating chamber 54) of downside and the inside part (storeroom 55) of bellying 36.Storeroom 55 is configured in the top that generates chamber 54.Dispose above-mentioned electrode 30 and level sensor 31 (with reference to Fig. 7) in generation chamber 54, generating chamber 54 generation brine electrolysis.The through hole 38 of rear wall 36A is communicated with storeroom 55 from rear side, the leading flank 39A of ultrasonic oscillator 39 via the hollow space of second annular component 43 and through hole 38 from trailing flank in storeroom 55.

Linearly the upper end that sucts pipe 56 of shape extension links to each other with partition wall 53 downwards, generates chamber 54 and storeroom 55 via the internal communication that sucts pipe 56.The lower end part that sucts pipe 56 is in leaning on the position of top than the bottom that generates chamber 54 and being immersed in the brine electrolysis that generates chamber 54.

In this case, from the part of the exhaust of electric blower 9 ejection as above-mentioned successively through connecting piece 26 and ingress pipe 27 (with reference to Fig. 5), flow into from the top tank house 34 generation chamber 54 inside and extruding generates the water surface T of the brine electrolysis of chamber 54 from the top.Thus, the brine electrolysis that generates chamber 54 rises in sucting pipe 56 and arrival storeroom 55, and accumulates in the storeroom 55.Thus, the brine electrolysis that generates in the chamber 54 can be drawn up and accumulated in the storeroom 55.

Then; When brine electrolysis accumulates brine electrolysis and arrives the position of leading flank 39A of ultrasonic oscillator 39 in storeroom 55; Produce mist through making ultrasonic oscillator 39 carry out ultrasonic vibration, and make it from through hole 41 (with reference to Fig. 7) the device external ejection of upside backward.

As above-mentioned, ultrasonic oscillator 39 is about 15 ° with respect to the angle of inclination of vertical direction.Thus; Even air outside gets in the storerooms 55 from through hole 41 and becomes bubble when through hole 41 (with reference to Fig. 7) through ultrasonic oscillator 39 of the brine electrolysis of storeroom 55; This bubble can be attached to the leading flank 39A of ultrasonic oscillator 39 yet inaccessible through hole 41, thereby move to the upper space of storeroom 55 apace.Thus, can prevent to hinder through hole 41 (with reference to Fig. 2) ejection of mist M from ultrasonic oscillator 39 because of bubble.

But, when utilization sucts brine electrolysis that pipe 56 will generate chamber 54 when sucting storeroom 55, be envisioned that at storeroom 55 generation bubbles and the through hole 41 of inaccessible ultrasonic oscillator 39.Therefore, from above mark off the casing 28 (bellying 36) of storeroom 55 roof 36B the through hole 57 that is communicated with storeroom 55 from the top is set, utilize air can through and this through hole 57 of the intransitable member of moisture (being called " filter element ") obturation.As filter element 58, can enumerate fluororesin multiple aperture plasma membrane (TEMISH) (registration mark).Because the bubble in that storeroom 55 produces is discharged to the outside through filter element 58, so can prevent because of the inaccessible through hole 41 of this bubble.In addition, the brine electrolysis in the storeroom 55 can be through filter element 58 and to external leaks.

Like this; Even in storeroom 55, produce bubble; Filter element 58 also can be released to bubble the outside of storeroom 55, so can prevent to make the inaccessible undesirable condition that causes electrolysis water smoke M to spray swimmingly from through hole 41 of the through hole 41 of ultrasonic oscillator 39 because of the bubble that in storeroom 55, produces.

In addition, because the air of storeroom 55 is flowed out to the outside of generation unit 20 from filter element 58, so correspondingly can in storeroom 55, accumulate brine electrolysis earlier to the water level that can begin to produce mist.Thus, can produce mist earlier.

Shutter 61 is supported to and can broad ways be slided by cover body 22 and framework 4.

Under backsight; The shutter 61 of intercommunicating pore 65 when the ejiction opening 23 of cover body 22 squints to the right is positioned at the position of cutting out (closed position), its with the part of the side that keeps left than intercommunicating pore 65 from the front side inaccessible ejiction opening 23 and from the hollow space of first annular component 42 of the inaccessible generation unit 20 of rear side.Under this state, through cutting off between the hollow space of shutter 61 with the ejiction opening 23 and first annular component 42.Therefore; Brine electrolysis in the casing 28 can not leak to device external to the hollow space and the ejiction opening 23 of first annular component 42 via the through hole 41 (with reference to Fig. 7) of ultrasonic oscillator 39; In addition, outside dust yet can not invaded the hollow space of first annular component 42 and is attached on the ultrasonic oscillator 39 from ejiction opening 23.

On the other hand, shown in figure 16, intercommunicating pore 65 is configured between the hollow space of the ejiction opening 23 and first annular component 42 if shutter in the closed position 61 is slided under backsight to the left, and then shutter 61 is configured in the position (open position) of opening.At this moment, the hollow space of the ejiction opening 23 and first annular component 42 is communicated with via intercommunicating pore 65.

With reference to Figure 15, force application component 62 is a compression spring long on width, and under backsight, it is inserted between the left part of left medial surface and shutter 61 of cover body 22.Force application component 62 utilizes has position (closing direction) application of force of the active force of stretching, extension trend to shutter 61 right side under backsight.

Pressing member 63 possesses along fore-and-aft direction columned axial region 67 that extends and the press section 68 that is located at the rearward end of axial region 67 integratedly.The rear end face of press section 68 linearly tilts on shape ground to right lateral side under backsight.Front end at axial region 67 is provided with flange part 67A integratedly, and this flange part 67A is flange shapely to radial outside from the periphery of axial region 67 and stretches out.

In addition, on main body of dust collector 2, be provided with the incorporating section 69 of the leading section of taking in axial region 67.Incorporating section 69 be along fore-and-aft direction extend roughly cylindric, it is open and inaccessible at front end in the rear end.The rear end of incorporating section 69 becomes the bending part 69A to the radially inner side bending.Pressing member 63 be accommodated at the leading section of axial region 67 under the state of incorporating section 69 can before and after slide.Leading section at axial region 67 is wound with the long helical spring 70 in front and back.This helical spring 70 is the compression spring, and it is inserted between the bending part 69A of flange part 67A and the rear end of incorporating section 69 of front end of axial region 67, the active force that utilization has stretching, extension trend to pressing member 63 integral body to the front side application of force.

Obtain pipe 64 for being bent into the tubulose of bent axle shape, one of which end 64A is connected with motor cover body 25, and the other end 64B links to each other with incorporating section 69.Thus, the inside of the inside of motor cover body 25 and incorporating section 69 (particularly being the zone than the forward side of flange part 67A of the front end of the axial region 67 of pressing member 63) is communicated with.

In this structure, shutter 61 is positioned at the closed position under the not driven state of electric blower 9.In addition, if drive electric blower 9, then obtained the inside that arrive incorporating sections 69 in the pipe 64 through obtaining because of obtaining pipe 64 from the part of the exhaust of electric blower 9 ejections.This exhaust is pushed to rear side the front end face of the axial region that is formed with flange part 67A 67 of pressing member 63.Thus; Pressing member 63 breaks away moving because of the active force that the part of the exhaust of bearing electric blower 9 overcomes helical spring 70 backward; At this moment, the rear end face of the inclination of the press section 68 of pressing member 63 is pushed the inclined plane 66A of the portion that is pressed 66 of shutter 61 to rear side.Thus, the left side effect of the portion of being pressed 66 is pushed in pressing force from press section 68 to rear side under backsight, the active force that shutter 61 overcomes force application component 62 slides to the left and arrives open position shown in Figure 16.That is, the part of the exhaust of pressing member 63 through bearing electric blower 9 active force that overcomes force application component 62 is opened shutter 61.

In addition; Under this state,, then stop to push the front end face of axial region 67 to rear side from the exhaust of electric blower 9 ejections if stop driving to electric blower 9; Therefore; Pressing member 63 turns back to the position of original front side under the active force of helical spring 70, corresponding to this, shutter 61 returns (with reference to Figure 15) to the closed position under the active force of force application component 62.

Like this, when electric blower 9 is driven (dust catcher is on-stream), owing to shutter 61 is opened, so electrolysis water smoke can be discharged (with reference to Figure 16) from open ejiction opening 23.On the other hand; If stop driving (running of dust catcher) to electric blower 9; Then shutter 61 close and ejiction opening 23 by inaccessible, the water that therefore can prevent casing 28 (with reference to Fig. 2) leaks or outside dust is invaded in the main body of dust collector 2 and is attached to ultrasonic oscillator 39 first-class bad situations (with reference to Figure 15) from ejiction opening 23 from ejiction opening 23.

Figure 17 (a) is the vertical view cutaway drawing of the switching mechanism 60 of generation unit 20 and variation, and it illustrates the state that shutter 61 is positioned at open position, and Figure 17 (b) is illustrated in the state that the middle shutter 61 of Figure 17 (a) is positioned at the closed position.

Shown in figure 17, also can the use switching mechanism 60 different with Figure 15 and Figure 16 structure.

In switching mechanism shown in Figure 17 60, at the front end face of the portion that is pressed 66 of shutter 61 above-mentioned inclined plane 66A is not set, be alternative in this, be formed with the inclined plane 66B that under backsight, tilts to forward right side at the rear end face of the portion of being pressed 66.

In addition, be provided with the pressing member 71 (closure element) different with above-mentioned pressing member 63 structures.Pressing member 71 possesses the press section 73 that the elongated axial region of fore-and-aft direction 72 is connected with front end with axial region 72 integratedly.The front end face of press section 73 tilts to forward right side under backsight.On press section 73, be provided with protuberance 73A integratedly, the right side of this protuberance 73A under backsight is outstanding.In addition, on the framework 4 of main body of dust collector 2, be provided with supporting convex 74 from front side and protuberance 73A opposed position on devices spaced apart ground.Between protuberance 73A and supporting convex 74, be inserted with the long force application component 75 in front and back.

Force application component 75 is the compression spring, the active force that its utilization has stretching, extension trend to pressing member 71 to the rear side application of force.At this, be formed with through hole 76 through axial region 72 in axial region 72 opposed position cover body 22 and pressing member 71.In Figure 17 (a), main body of dust collector 2 is common state (with reference to Fig. 2), to rear side by the pressing member 71 of the application of force in, axial region 72 is outstanding to the back outside of cover body 22 from through hole 76.At this moment, shutter 61 is positioned at above-mentioned open position.Above-mentioned force application component 62 is located at open position with shutter 61 to opening the direction application of force.

Under this state; If being erected, main body of dust collector 2 becomes receiving state (with reference to Figure 11); Then from outstanding laterally the axial region 72 such and floor X butt shown in Figure 17 (b) of the through hole 76 of cover body 22; Thus, pressing member 71 overcomes the active force of force application component 75 and slides to a side of leaving floor X (being in the upside of the main body of dust collector 2 of receiving state).Thus, the front end face of the inclination of the press section 73 of pressing member 71 (being the upper surface when main body of dust collector 2 is in receiving state) is pushed the inclined plane 66B of the portion that is pressed 66 of shutter 61 from the below.Thus, the left side effect of the power that the portion of being pressed 66 is pushed in press section 73 under backsight, the active force that shutter 61 overcomes force application component 62 slides to the left and arrives the closed position.At this moment, the ratio intercommunicating pore 65 of the shutter 61 inaccessible ejiction opening 23 of part of (in Figure 17 (b), being downside) on the right side.That is the pressing member 71 that, has an axial region 72 is closed shutter 61 through the active force that overcomes force application component 62 with floor X butt.

On the other hand; Under this state; When make main body of dust collector 2 from receiving state become common state or with main body of dust collector 2 when floor X lifts, the axial region 72 of pressing member 71 is butt floor X no longer, member 71 is pushed so the portion that is pressed 66 of shutter 61 no longer is pressed.Corresponding to this, shutter 61 turns back to open position (with reference to Figure 17 (a)) under the active force of force application component 62.

Like this, when main body of dust collector 2 is not in receiving state (dust catcher running in), opened by force application component 62 application of forces owing to open and close 61, so can be from open ejiction opening 23 discharge electrolysis water smokes (with reference to Figure 17 (a)).In addition; When main body of dust collector 2 is in receiving state (when the running of dust catcher stops); Then because shutter 61 cuts out ejiction opening 23 by inaccessible, so the water that can prevent casing 28 (with reference to Fig. 2) spills or outside dust invades in the main body of dust collector 2 and is attached to the undesirable condition on the ultrasonic oscillator 39 from ejiction opening 23 from ejiction opening 23.

Figure 18 (a) is the rearview of generation unit 20, and Figure 18 (b) is the right side view of generation unit 20.Figure 19 (a) is the right view that is in the rear section of the main body of dust collector 2 under the common state, and Figure 19 (b) is illustrated in the state after the middle main body of dust collector 2 of Figure 19 (a) erects.

Next, above-mentioned level sensor 31 is described.

With reference to Figure 18 (b), level sensor 31 is accommodated in the tank house 34 in the casing 28, and the water level of the water in the tank house 34 is detected.Particularly, level sensor 31 does not contact the water deficiency that detects tank house 34 with water through its bottom.

Level sensor 31 is thin tabular in the elongated front and back of above-below direction.Level sensor 31 under rearview to be configured in the position with the front side (in Figure 18 (b), being the left side) of said electrode 30 devices spaced apart with pair of electrodes 30 overlapping modes.That is, level sensor 31 is positioned at than back surperficial 13 the position (with reference to Figure 19) of pair of electrodes 30 away from the framework 4 of main body of dust collector 2.In addition, the lower end of level sensor 31 is positioned at the position of being partial to the below than the above-below direction central authorities of tank house 34 slightly.

With reference to Figure 19 (a); Be in common state and water accumulates under the situation of predetermined water level at main body of dust collector 2 in tank house 34; The bottom of level sensor 31 is located under the water surface T of the water that accumulates predetermined water level in the tank house 34, thereby is immersed in the water of tank house 34.Switch in the water of level sensor 31 because of bottom immersion tank house 34, detect water thus and in tank house 34, accumulated predetermined water level.

Otherwise if the water level of tank house 34 becomes lower than predetermined water level, then level sensor 31 leaves to the top from the water surface T of tank house 34.Thus, because of water no longer contacts with level sensor 31, so level sensor 31 is no longer switched on.Therefore, level sensor 31 detects water and in tank house 34, does not accumulate the predetermined water level water of the tank house 34 (not enough).

In tank house 34, do not accumulate under the state of predetermined water level at water, electrode 30 does not contact with water with ultrasonic oscillator 39 (with reference to Fig. 2).If under this state, electrode 30, ultrasonic oscillator 39 are applied voltage, then not only do not generate brine electrolysis and mist, but also possibly cause electrode 30, ultrasonic oscillator 39 to generate heat and breakage.Therefore, in main body of dust collector 2, the not contact with water if level sensor 31 becomes then stops electrode 30, ultrasonic oscillator 39 are applied voltage (that is the running of generation unit 20).Particularly, be located at control part 100 on the main body of dust collector 2 (with reference to after Figure 31 of stating) according to level sensor 31 no longer this situation of contact with water (level sensor 31 detects not enough this situation of water of tank house 34) running of generation unit 20 is stopped.Utilize this structure, no matter whether the water deficiency can both prevent generation unit 20 runnings, thereby can realize the protection to electrode 30, ultrasonic oscillator 39.

In addition; Shown in Figure 19 (b); Erect and become under the situation of receiving state at main body of dust collector 2, the water surface T of tank house 34 and floor X, level sensor 31 are parallel, and level sensor 31 configured in one piece are in contact with water than the high position of water surface T of the water of tank house 34 and no longer.Follow in this, the running of generation unit 20 stops.Particularly, because level sensor 31 contact with water no longer makes the running of generation unit 20 stop so controlling 100 (with reference to Figure 31) in view of the above.Thus, be in the situation of receiving state generation unit 20 runnings though can prevent main body of dust collector 2.

In addition, suppose under ultrasonic oscillator 39 and situation that water contacts, though can prevent that main body of dust collector 2 is in receiving state ultrasonic oscillator 39 and produces mists and blow to floor X and go up and this undesirable condition of adhesional wetting floor X.

Like this, in order under the situation that is in receiving state at main body of dust collector 2 generation unit 20 not to be turned round, be at main body of dust collector 2 under the situation of receiving state, the water surface T that level sensor 31 is configured to leave to the top tank house 34 gets final product.

Figure 20 (a) is the rearview of generation unit 20 and electric blower 9, and it illustrates a part with section, and Figure 20 (b) is the major part enlarged drawing of Figure 20 (a), and Figure 20 (c) is illustrated in the state after ball valve 80 come-ups among Figure 20 (b).

With reference to Figure 20 (a), be inserted with second filter member 77 that constitutes by above-mentioned fluororesin multiple aperture plasma membrane (TEMISH registration mark) in the bonding part of ingress pipe that will in the tank house 34 of generation unit 20, guide 27 and tank house 34 (casing 28) from the exhaust of above-mentioned electric blower 9.Therefore, can prevent that the water in the tank house 34 from leaking to electric blower 9 through ingress pipe 27.Need to prove that second filter member 77 is not limited to be configured in the bonding part of ingress pipe 27 and tank house 34 (casing 28), also can be configured in ingress pipe 27 or connecting piece 26 midway.

In addition, the person in charge 26A and the looped pipeline 26B that divide expenditure to be connected on the way therein the connecting piece 26 that connects between the motor cover body 25 of taking in electric blower 9 and the ingress pipe 27 with ingress pipe 27.

With reference to Figure 20 (b), looped pipeline 26B is the pipe shape, be bent into approximate right angle after it extends to the left under backsight and to above extend.Be formed with the connected entrance 78 that makes inner and external communications in the upper end of looped pipeline 26B.

In addition, the inner peripheral surface in the upper end of looped pipeline 26B is being formed with the taper seat 79 towards the upside hole enlargement than connected entrance 78 by downside.In addition, be built-in with spherical ball valve 80 in the upper end of looped pipeline 26B.Ball valve 80 can slide up and down in the inside of the upper end of looped pipeline 26B, under normal conditions, its under the deadweight effect from above contact taper seat 79.Thus, through ball valve 80 the contact site of ball valve 80 and taper seat 79 from above the inside of inaccessible looped pipeline 26B.Need to prove that under this state, ball valve 80 does not contact with taper seat 79 part in addition at the inner peripheral surface of looped pipeline 26B.

In addition, in electric blower 9, can adjust attraction, according to the variation of attraction, from the pressure change of the exhaust of electric blower 9 ejection.The water (with reference to Figure 20 (a)) in the tank house 34 is depressed through connecting piece 26 (being responsible for 26A) and ingress pipe 27 in the part of exhaust inside from motor cover body 25 as above-mentioned.Thus, the water in the tank house 34 arrive ultrasonic oscillators 39 and become mist through sucting pipe 47, and under the pressure of exhaust and discharge to device external.

At this, even hope is also discharged mist with the constant force and velocity of a current from the pressure change of the exhaust of electric blower 9 ejections to device external.Therefore, above-mentioned ball valve 80 plays a role.

Particularly, the part of the exhaust of discharging from electric blower 9 is through connecting piece 26, and still, this exhaust not only flows in connecting piece 26 and is responsible for 26A, also flows into looped pipeline 26B (with reference to Figure 20 (a)).The ball valve 80 (with reference to the thick arrow of Figure 20 (b)) of the contact taper seat 79 from the top is pushed in the exhaust that flows into looped pipeline 26B from the below.At this moment, if the pressure ratio of exhaust regulation is slight greatly, even then ball valve 80 is pushed in exhaust, ball valve 80 can not move yet.

On the other hand, if more than the size of the pressure of exhaust for regulation, then shown in Figure 20 (c), push ball valve 80 through exhaust, ball valve 80 is from hereto floating with taper seat 79 position contacting.Thus, between ball valve 80 and taper seat 79, be formed with gap Z,, and discharge (with reference to the thick arrow of Figure 20 (c)) to outside (outside of connecting piece 26) from connected entrance 78 so exhaust arrives the upper end of looped pipeline 26B through gap Z.Thus, become slight greatly than said regulation of the pressure of the exhaust in the connecting piece 26.

Like this; Owing to ball valve 80 plays a role as so-called vent valve or barometric fluctuation valve; Even so, also can make from being responsible for pressure that 26A flows into the exhaust in the tank house 34 and be maintained in slight greatly than said regulation from the pressure change of the exhaust of motor air blast 9 ejection.Thus, in generation unit 20, can mist be discharged to device external (with reference to Fig. 2) with the constant all the time force and velocity of a current.

In addition, under the situation that main body of dust collector 2 is put upside down, because ball valve 80 leaves taper seat 79 under the effect of deadweight, so form above-mentioned gap Z.Therefore, the exhaust that flows into connecting piece 26 from electric blower 9 ejections is discharged to the outside from connected entrance 78 via this gap Z, can not flow into tank house 34.Therefore, even under the state that main body of dust collector 2 is put upside down, also can prevent to discharge mist from generation unit 20.

Need to prove,, then can adopt the known configurations beyond the ball valve 80 as long as can constitute above-mentioned vent valve.

In addition, shown in figure 10, also can spherical ball valve 81 be configured to move freely in the inside that sucts pipe 47 of generation unit 20.Because ball valve 81 obturations suct the inside of pipe 47 under the state in exhaust does not flow into tank house 34, so the water of tank house 34 can not leak by the through hole 41 (with reference to Fig. 7) from ultrasonic oscillator 39 from sucting pipe 47 arrival ultrasonic oscillators 39.On the other hand, if exhaust flows in the tank house 34, ball valve 81 is pressed in this exhaust, thereby at ball valve 81 and suct to manage between 47 the inner peripheral surface and form the gap.Therefore, push and flow into the water that sucts in the pipe 47 gap through ball valve 81 and the inner peripheral surface that sucts pipe 47 from tank house 34 and arrive ultrasonic oscillator 39, thereby become mist and discharge to device external by exhaust.That is, also ball valve 81 can be set, so that the water of tank house 34 does not leak from ultrasonic oscillator 39 under the state in exhaust does not flow into tank house 34.

Figure 21 (a) is the rearview of generation unit 20, and it illustrates a part with section, and Figure 21 (b) to (d) is that the B-B of Figure 21 (a) is to looking cutaway view.

For the water level of the water that detects tank house 34, also can utilization structure and the above-mentioned different water level detecting unit 82 of level sensor 31 (with reference to Figure 18 and Figure 19).

With reference to Figure 21 (b), this water level detecting unit 82 possesses buoy 83, reflecting member 84, pair of optical formula sensor 85A, 85B.

Reflecting member 84 serve as reasons can be catoptrical the material wire or the band shape (membrane-like) that form, under the last state that extends below, its bottom links to each other with the bottom of tank house 34, and the upper end links to each other with buoy 83.Buoy 83 moves up and down according to the variation of the water level (water surface T) of the water in the tank house 34, and corresponding to this, reflecting member 84 can stretch and change length up and down. Optical sensor 85A, 85B possess light-emitting component (not shown) and the photo detector (not shown) that is made up of infrared LEDs etc. separately, and this photo detector is accepted in the light that horizontal direction is sent, to run into reflecting member 84 and the light of reflection by light-emitting component (not shown).Optical sensor 85A among optical sensor 85A, the 85B is configured in the position higher than optical sensor 85B.

Shown in Figure 21 (b), in tank house 34, accumulate under the state (full water state) more than the predetermined water level at water, optical sensor 85A, 85B are all consistent with reflecting member on short transverse.In this case, in optical sensor 85A, 85B, be, the light that light-emitting component (not shown) sends is reflected member 84 reflections and receives light by photo detector (not shown).Water level detecting unit 82 is through all being that light by reflecting member 84 reflection is received the situation of light to detect full water state by photo detector in optical sensor 85A, 85B.

On the other hand; Shown in Figure 21 (c); When water level during from full water state decline ormal weight, electrode 30 does not immerse in the water of tank house 34 fully, even owing under this state, electrode 30 is applied voltage; Also not only can't generate brine electrolysis but also possibly cause electrode 30 heatings and breakage, so need stop electrode 30 is applied voltage and guard electrode 30.The water level of this moment is called the electrode protection water level.

At this moment, the optical sensor 85A of upside is positioned at than the high position of emission member 84, and the optical sensor 85B of downside continues consistent with reflecting member 84 on short transverse.In this case, only in optical sensor 85, the light that light-emitting component (not shown) sends receives light by reflecting member 84 reflections by photo detector (not shown).Water level detecting unit 82 is positioned at this situation of electrode protection water level through only in optical sensor 85B, receiving the situation of light to detect current water level by photo detector to the light of the reflection of reflecting member 84.Corresponding to this, after the control part 100 (with reference to Figure 31) stated stop electrode 30 is applied voltage.But, be positioned at water level under the situation of electrode protection water level, owing in tank house 34, have enough brine electrolysis that is used for producing mist at ultrasonic oscillator 39, so do not stop ultrasonic oscillator 39 is applied potential pulse and continues to discharge mist M (with reference to Fig. 2).

In addition, shown in Figure 21 (d), in tank house 34, drop under the state (exsiccosis) that uses up than low and water base of electrode protection water level at water level, optical sensor 85A, 85B are not consistent with emission member 84 in short transverse.In this case, no matter in which of optical sensor 85A, 85B, the light of light-emitting component (not shown) all can't help reflecting member 84 reflections, therefore can not receive light by photo detector (not shown).Water level detecting but unit 82 is not received the situation of light to detect exsiccosis by photo detector through the light that light-emitting component sent in optical sensor 85A, 85B.In this case, because in tank house 34, be not used in the brine electrolysis that produces mist at ultrasonic oscillator 39 basically, so stop ultrasonic oscillator 39 is applied potential pulse in order to protect ultrasonic oscillator 39.

Like this, according to water level detecting unit 82, can also detect their middle states (electrode protection water level) owing to not only can detect full water state and exsiccosis, so can carry out proper process corresponding to each water level in the tank house 34.Proper process is meant; Under full water state, electrode 30 and ultrasonic oscillator 39 both sides are applied voltage; When water level is positioned at the electrode protection water level, only stop electrode 30 is applied voltage, under exsiccosis, stop electrode 30 and ultrasonic oscillator 39 both sides are applied voltage.

Figure 22 is the right view of the rear section of main body of dust collector 2, and it illustrates a part that comprises generation unit 20 with section.Figure 23 illustrates the cover body 22 that makes among Figure 22 to opening the state that direction begins to rotate.Figure 24 illustrates the cover body 22 that makes among Figure 23 to opening the state that direction is further rotated.Figure 25 illustrates the state that the cover body 22 that makes among Figure 24 rotates to closing direction.

With reference to Figure 22; Be installed at generation unit 20 under the state of framework 4 of main body of dust collector 2; The body terminal 49 of framework 4 is connected with the splicing ear 33 of generation unit 20 from the below, and the other end 27B with the ingress pipe 27 of generation unit 20 is connected the connecting piece 26 of framework 4 from the below.

At this, the turning cylinder 22A of the bottom of cover body 22 is from the end abutment of rear side (right side of Figure 22) with the back downside of generation unit 20.In addition, be provided with the holding section 22B that extends with side-prominent forward mode integratedly in the bottom of cover body 22.Under cover body 22 closing state, holding section 22B slips into the downside of end of the back downside of generation unit 20.In addition, the lower surface at the upper portion that extends along general horizontal direction of the cover body 22 of L word shape is provided with side-prominent flank 22C downwards integratedly.Under cover body 22 closing state, flank 22C compresses generation unit 20 from the top, thus, can firmly keep connection status and the other end 27B of ingress pipe 27 and the connection status of connecting piece 26 of splicing ear 33 and body terminal 49.

If the cover body 22 that so will be in closed condition layback backward draws, then cover body 22 beginnings are center back side (be clockwise direction among Figure 22) rotation with turning cylinder 22A.So, shown in figure 23, as the part of cover body 22 and the holding section 22B that rotates compresses the end of the back downside of generation unit 20 from the below.Thus, generation unit 20 rises overally, and splicing ear 33 begins from body terminal 49 to break away to upside, and the other end 27B of ingress pipe 27 begins to break away to upside from connecting piece 26.

In addition, if further rotate cover body 22 to equidirectional, then holding section 22B has further pressed generation unit 20.Thus, shown in figure 24, generation unit 20 is whole further to rise, and splicing ear 33 breaks away to upside from body terminal 49 fully, and the other end 27B of ingress pipe 27 breaks away to upside from connecting piece 26 fully.Thus, because generation unit 20 breaks away from from framework 4 fully, the generation unit 20 that breaks away from is safeguarded (to casing 28 make-up water etc.) so can advance.

In addition; If after the generation unit 20 after will safeguarding is placed in the position of Figure 24, make cover body 22 to rotating with direction in the opposite direction hereto, then shown in figure 25; Holding section 22B separates to downside from generation unit 20, and the flank 22C of the upside of cover body 22 compresses generation unit 20 from the top.Thus, generation unit 20 is whole to descend, at this moment, splicing ear 33 from upside near body terminal 49, and the other end 27B of ingress pipe 27 from upside near connecting piece 26.If cover body 22 is further rotated to equidirectional, then shown in figure 23, generation unit 20 further descends, and splicing ear 33 begins to be connected with body terminal 49 from upside, and the other end 27B of ingress pipe 27 begins to be connected with connecting piece 26 from upside.In addition, shown in figure 22, if cover body 22 is further rotated to equidirectional, then generation unit 20 stops to descend, and at this moment, splicing ear 33 is connected with body terminal 49 fully, and the other end 27B of ingress pipe 27 is connected with connecting piece 26 fully.

Figure 26 (a) is the vertical view of the ultrasonic oscillator 39 of first structure, and Figure 26 (b) is the cutaway view of the ultrasonic oscillator 39 of Figure 26 (a).

Next, ultrasonic oscillator 39 is elaborated.

With reference to Figure 26; Strictly speaking, ultrasonic oscillator 39 comprises: a pair of distribution 90A, the 90B that are formed with the discoideus metallic plate 87 of above-mentioned through hole 41, on a side of metallic plate 87, are connected with metallic plate 87 and piezoelectrics 89 respectively through the bonding circular piezoelectrics 89 of electrically conducting adhesive 88, through scolder.As the material of metallic plate 87, can use stainless steel etc.The bonding agent of electrically conducting adhesive 88 for having electric conductivity for example can be enumerated DOTITE (registration mark).

Piezoelectrics 89 are for example formed by piezoelectric ceramics, and it produces vibration when being applied in potential pulse.The external diameter of piezoelectrics 89 is littler than the external diameter of metallic plate 87, and all through holes 41 all expose from the hollow space of piezoelectrics 89.Be formed with electrode 91 in the sides with the opposition side bonding side of metallic plate 87 piezoelectrics 89, this electrode 91 constitutes through making silver-colored sintering.

Distribution 90A, 90B are covered by the cover body with insulating properties 92.In distribution 90A, the fore-end that exposes through strip off cover body 92 more leans on the part of radial outside to be connected (with reference to Figure 26 (a)) through scolder with the ratio piezoelectrics 89 of a said side of metallic plate 87.In distribution 90B, the fore-end that exposes through strip off cover body 92 is connected with the electrode 91 of piezoelectrics 89 through scolder.Under this state, the part almost parallel ground that is covered by cover body 92 of distribution 90A, 90B extends (with reference to Figure 26 (a)).

When electric current flowed between distribution 90A, 90B, piezoelectrics 89 were applied in potential pulse and vibrate.Thus, as above-mentioned, ultrasonic oscillator 39 body vibrations.

At this, because more crisp as the electrode 91 of sintered body of silver, the front end 93 that situation possibly cause distribution 90B so the vibration that distribution 90B produces during because of running is stretched or distribution 90B is stretched when safeguarding etc. is from electrode 91 disengagings.

Therefore; Form the leading section of distribution 90B (part that is not covered by cover body 92) long, the ratio piezoelectrics 89 that the bonding agent 95 (silicon bonding agent (silicon bond) etc.) through having insulating properties bonds to a said side of metallic plate 87 with the part midway 94 of the leading section of distribution 90B lean on the part of radial outside.

Like this, even distribution 90B is stretched, the power of stretching distribution 90B also can be born and can not arrive front end 93 by the part midway 94 of distribution 90B.In addition, the load of the part that is covered by cover body 92 of distribution 90B is also born and can not be arrived front end 93 by part 94 midway.The front end 93 that therefore, can prevent distribution 90B is from electrode 91 disengagings.Thus, can the front end 93 of distribution 90B and the status of electrically connecting of electrode 91 be remained stable status.

Figure 27 (a) is the vertical view of the ultrasonic oscillator 39 of second structure, and Figure 27 (b) is the cutaway view of the ultrasonic oscillator 39 of Figure 27 (a).Figure 28 (a) is the vertical view of the ultrasonic oscillator 39 of the 3rd structure, and Figure 28 (b) is the cutaway view of the ultrasonic oscillator 39 of Figure 28 (a).Figure 29 (a) is the vertical view of the ultrasonic oscillator 39 of the 4th structure, and Figure 29 (b) is the cutaway view of the ultrasonic oscillator 39 of Figure 29 (a).Figure 30 is by the enlarged drawing of the part that broken circle surrounded in Figure 29 (b).

In addition, as with Figure 26 various structure, enumerate out second structure shown in Figure 27, the 3rd structure shown in Figure 28, the 4th structure shown in Figure 29.

In second structure shown in Figure 27, through electrically conducting adhesive 88 metallic plates such as stainless steel 96 are attached on the electrode 91, through scolder the front end 93 of distribution 90B is connected to this metallic plate 96.Overlook down, metallic plate 96 is bigger than the front end 93 of distribution 90B, and the front end 93 of distribution 90B partly is connected with the substantial middle of metallic plate 96.The situation that is connected in electrode 91 with the front end 93 of distribution 90B is compared, and the front end 93 of distribution 90B can be firmly attached to metallic plate 96 more.

So, even distribution 90B is stretched, the front end 93 of distribution 90B can not break away from from metallic plate 96 yet.In addition because metallic plate 96 is connected with electrode 91 to compare bigger contact area with the situation that front end 93 is connected in electrode 91, so the power of stretching distribution 90B because of reducing in metallic plate 96 dispersions, so metallic plate 96 can not peeled off from electrode 91.Therefore, can keep the front end 93 of distribution 90B and the status of electrically connecting of electrode 91 with stable status.

In the 3rd structure shown in Figure 28, not through scolder but bond on the electrode 91 through the front end 93 of electrically conducting adhesive 88 with distribution 90B.Because electrically conducting adhesive 88 has elasticity under the state that solidifies, so even distribution 90B is stretched, the generation strain relaxes the power of stretching distribution 90B between front end 93 that also can be through distribution 90B and the electrode 91.The front end 93 that therefore, can prevent distribution 90B is from electrode 91 disengagings.Thus, can keep the front end 93 of distribution 90B and the status of electrically connecting of electrode 91 with stable status.

In the 4th structure shown in Figure 29, adopt flexible cable 97.Flexible cable 97 is for having flexible laminated structure, and it is bent into the bent axle shape along the step of metallic plate 87 and piezoelectrics 89.Shown in figure 30, flexible cable 97 comprises the conductor 98 and the dielectric film 99 that covers conductor 98 of the sheet with electric conductivity.In addition, be benchmark with the attitude of Figure 30, the left part of conductor 98 not to be insulated the lower surface that film 99 covers bonding through electrically conducting adhesive 88 and electrode 91, and the front end 93 of distribution 90B is connected with the upper surface that is not insulated film 99 coverings of the right part of conductor 98.

At this, distribution 90B is the leaf spring of rubber-like metal, and front end 93 is connected with the upper surface elasticity that is not insulated film 99 coverings of the right part of conductor 98.Therefore, even distribution 90B moves because of vibration waits, the front end 93 of distribution 90B also only can be with respect to the slide that film 99 covers that is not insulated of the right part of conductor 98, thereby flexible cable 97 can not peeled off from electrode 91.Therefore, even distribution 90B motion can keep the front end 93 of distribution 90B and the status of electrically connecting of electrode 91 with stable status.Need to prove that another one distribution 90A also can be leaf spring, and be connected (with reference to Figure 29 (b)) with metallic plate 87 elasticity.

Figure 31 is the block diagram that is used to explain the electrical structure of electric dust collector 1.

Next, the electrical structure of electric dust collector 1 is described with reference to Figure 31.

Electric dust collector 1 possess control part 100 (shut-down mechanism, the running controlling organization, applying mechanism, forbid mechanism).Control part 100 possesses CPU and stores the memory (ROM, RAM etc.) of its program etc., and the processing that puts rules into practice according to program.

Described electric blower 9, generation unit 20 and mist switch 50 are electrically connected with control part 100, and furthermore, strong and weak switch 101 (selection operation portion) and timing portion 102 are electrically connected.

Begin the running (electrode 30 is applied voltage and ultrasonic oscillator 39 is applied potential pulse) of generation unit 20 through user's operation (connection) mist switch 50.

Strong and weak switch 101 is carried out the part (carrying button) of selection operation when the attraction of electric blower 9 is adjusted by the user, it is located on main body of dust collector 2 (with reference to Fig. 2) end face etc.Strong and weak switch 101 can switch to prime time 101A and weak shelves 101B.If strong and weak switch 101 is switched to prime time 101A, then control part 100 turns round to produce bigger attraction electric blower the last 9.If strong and weak switch 101 switches to weak shelves 101B, then control part 100 makes electric blower 9 carry out weak running to produce smaller attraction.That is, the running of electric blower 9 can switch to strong running and weak running, can select the running of electric blower 9 through operating strong and weak switch 101.

At this, when in strong running, producing bigger attraction, become bigger from the pressure of the exhaust of electric blower 9, when in weak running, producing smaller attraction, then the pressure from the exhaust of electric blower 9 becomes smaller.As above-mentioned; Because under the pressure of the exhaust of the electric blower 9 in entering into casing 28; Brine electrolysis in the casing 28 supplies to ultrasonic oscillator 39 (with reference to Fig. 2 and Fig. 5); So under the state of water no show ultrasonic oscillator 39, are in strong running and the weak running which according to the running of electric blower 9, the time changing that the brine electrolysis in the casing 28 are supplied with to ultrasonic oscillator 39.

In addition; Because generation unit 20 utilizes the pressure of the exhaust of electric blower 9 that mist is discharged to device external; Begin the running of generation unit 20 so control part 100 is connected mist switch 50 according to the user, electric blower the last 9 turned round or weak running.

Timing portion 102 carries out timing.

Figure 32 is the flow chart that is illustrated in the order of the processing of implementing in the electric dust collector 1.

Figure 33 is the time diagram of the operating state separately of expression electric blower 9 and generation unit 20.

Next, with reference to Figure 32, the processing that control part 100 (with reference to Figure 31) is carried out describes.

Control part 100 is kept watch on mist switch 20 and whether is connected (step S1).If mist switch 50 is connected (be " being " at step S1), then control part 100 confirms that strong and weak switches 101 (with reference to Figure 31) are by force or weak (that is, that selection is prime time 101A or weak grade 101B) (step S2).

If that select is prime time 101A, the then strong running of control part 100 beginning electric blowers 9 on the other hand, though mist switch 50 is connected, also makes the running of generation unit 20 stop (OFF) (step S3).Thus, though the exhaust of electric blower 9 flows in the tank house 34 of generation unit 20, mist can not discharged (with reference to Fig. 2) to device external.

Then, according to the timing of timing portion 102 (with reference to Figure 31), during through the stipulated time (is three seconds at this) (in step S4, being " being "), control part 100 makes the running of generation unit 20 begin (ON) (step S5) after mist switch 50 is connected.Thus, mist M discharges (with reference to Fig. 2) to device external under the pressure of the exhaust of electric blower 9.

In addition, to finish the user under the situation of discharge of mist, mist switch 50 is broken off.When breaking off (in step S6, being " being ") at mist switch 50, control part 100 makes the running of generation unit 20 stop (OFF) (step S7).Thus, finish the discharge of mist.Need to prove that at this moment, control part 100 also can stop the running of electric blower 9.

On the other hand;, mist switch 50 (in step S1, is " being ") when connecting; If select weak shelves 101B, then control part 100 does not make electric blower 9 carry out weak running and it is turned round by force, on the other hand; Though mist switch 50 is connected, and the running of generation unit 20 is stopped (OFF) (step S8).Thus, though the exhaust of electric blower 9 flows in the tank house 34 of generation unit 20, mist is not discharged (with reference to Fig. 2) to device external.

Then; Timing according to timing portion 102; During through three seconds (is " being " at step S9), then control part 100 switches to weak running with the running of electric blower 9 from strong running, and the running of generation unit 20 is begun (ON) (step S10) after mist switch 50 is connected.Thus, mist M discharges (with reference to Fig. 2) to device external under the pressure of the exhaust of electric blower 9.

Then, when mist switch 50 broke off (in step S6, being " being "), control part 100 made the running of generation unit 20 stop (OFF) (step S7).Thus, finish the discharge of mist.Need to prove that at this moment, control part 100 also can make the running of electric blower 9 stop.

Like this,,, under the situation of selecting weak shelves 101B, when mist switch 50 is connected, connect the back at mist switch 50 and force to make electric blower 9 carry out the strong running in three seconds, break off generation unit 20 simultaneously with reference to the time diagram of Figure 33 through the processing of step S8 to S10.Then, after connecting through three seconds from mist switch 50, the running of electric blower 9 switches to weak running, and makes generation unit 20 entrys into service.

In addition; Under the situation of selecting prime time 101A; When mist switch 50 was connected, any moment before mist switch 50 is disconnected all made electric blower the last 9 turn round, and made generation unit 20 shut down (the step S3 of Figure 32) in three seconds and connected at mist switch 50.Then, after connecting through three seconds, make generation unit 20 entrys into service (the step S5 of Figure 32) from mist switch 50.

Promptly; Under the situation that mist switch 50 is connected; No matter select among prime time 1014A and the weak shelves 101B which, owing to electric blower the last 9 turned round connecting three seconds inner control portions 100, so in the bigger exhaust inflow tank house 34 of pressure from mist switch 50.Thus, originally tank house 34 in, be extruded to device external from the through hole 41 (with reference to Fig. 7) of ultrasonic oscillator 39 with the air that sucts in the pipe 47, alternative this air, tank house 34 interior brine electrolysis arrive ultrasonic oscillator 39 (with reference to Fig. 2) apace.

In addition, in these three seconds,, stop the vibration (running of generation unit 20) (the step S3 of Figure 32 and step S8) of ultrasonic oscillator 39 in order to prevent not break down there being ultrasonic oscillator 39 vibration heatings under the state of water.That is, control part 100 is being forbidden ultrasonic oscillator 39 is applied potential pulse before through three seconds stipulated time by operation from mist switch 50.Then, after through these three seconds, ultrasonic oscillator 39 vibrations (step S5 among Figure 32 and step S 10), thus, utilization arrives the brine electrolysis of ultrasonic oscillator 39 and generates mist M and discharge (with reference to Fig. 2) to device external.Promptly; Brine electrolysis in casing 28 supplies to before the ultrasonic oscillator 39; Owing to ultrasonic oscillator 39 is not applied potential pulse, so can prevent that ultrasonic oscillator 39 is because of being applied in the unfavorable condition that potential pulse causes ultrasonic oscillator 39 to break down not being supplied under the state of brine electrolysis.

In addition, so, under the situation that mist switch 50 is connected, no matter select among prime time 101A and the weak shelves 101B which, can both mist M be discharged to device external (with reference to Fig. 2) at synchronization.

Above-mentioned three seconds is in order when electric blower the last 9 turned round, to make the brine electrolysis in the tank house 34 arrive the 39 needed times of ultrasonic oscillator; But; Be alternative in this; Make the brine electrolysis tank house 34 in arrive ultrasonic oscillator 39 when carrying out weak running at electric blower 9, need spend about 20 seconds.Therefore, connect and select at mist switch 50 and make electric blower 9 carry out weak running under the situation of weak shelves 101B, then compare and to produce time lag and bring sense of discomfort to the user with the situation that electric blower the last 9 turned round.Need to prove, can suitably set this stipulated time of three seconds according to the performance of electric blower 9.

Therefore; Under the situation that mist switch 50 is connected; No matter select among prime time 101A and the weak shelves 101B which; In connected at mist switch 50 three seconds, electric blower the last 9 turned round, and the brine electrolysis in the casing 28 are supplied with apace with the identical all the time moment (through three seconds the moment) to ultrasonic oscillator 39.Then, through after through three seconds, making ultrasonic oscillator 39 vibrations immediately, can make mist M discharge (with reference to Fig. 2) in certain moment all the time.In this case; When the user operates mist switch 50; No matter the running of electric blower 9 is chosen to any in strong running and the weak running through operating strong and weak switch 101; All there is not above-mentioned time lag basically and discharges electrolysis water smoke M in the identical moment all the time, thereby can not feel well.Thus, realize the raising of ease of use.

In addition, when through after this stipulated time of three seconds, control part 100 makes electric blower 9 utilize strong running that strong and weak switch 101 selects and a certain mode in the weak running turn round (step S5 and step S10) in advance with the user.

The invention is not restricted to the embodiment of above explanation, it can carry out various changes in the scope of claims.
