Background technology
Typical electric cleaner, the suction air-flow that contains dust is through sucking annex (suction nozzle) in suction line enters dust-absorbing element.Herein, the air-flow that contains dust passes to be installed in the filter in the dust-absorbing element and to be filtered device and absorbs.
In the collection process of dust, if large-sized dirt such as paper scrap, mud or similar thing are sucked morely, filter is very fast blocked, causes suction to descend rapidly.Therefore, filter must often be cleaned, and in fact, often cleaning and filtering also is to cause an inefficient subject matter.In order to address this problem, a kind of system is proposed, in this system, a cyclone type dust separator is placed on the middle part that connects the suction line that sucks annex and main body of dust collector.Like this, bigger dirt is caught and removed to the cyclone type dust separator.
In the cyclone type dust separator in the Japan Patent No.3102864 that has disclosed, the lower end that is used near the air the eddy current is drawn into the blast pipe in the main body of dust collector is sealed.Be formed with a lot of thin through holes on the surface, outside of this pipe, air is inhaled into through these thin through holes, is discharged in the main body of dust collector then.In this structure, separated dirt is collected into one downwards in the dirt feeder that stretches along the blast pipe circumferencial direction (dirt collecting part) from eddy current.
On the other hand, in the cyclone type dust separator of day patent application No.2003-135336 of the present disclosure and H10-8519, near the center of the open lower end of blast pipe in the face of the dust separating part of generation vortex flow, the bottom of dust separating part communicates with a dust arrester, dust arrester by funnel type dust collect mouth be located at dust separating part below.In this structure, collect mouth by the separated dust of the eddy current in the dust collection unit by dust and drop in the dust arrester.
But in the system of Japan Patent No.3102864, the dust separated by the centrifugal force in the eddy current guides downwards along the dust collecting trough internal perisporium; Therefore, dust can efficiently be separated with air.Yet because flowing of eddy current enters into dust collecting trough inside along the dust collecting trough internal perisporium, the air of dust collecting trough inside can be subjected to eddy current.As a result, the dust that is collected in the dust collecting trough bottom is taken away by this air mobile (eddy current), and might discharge from blast pipe.These dusts cause the plugged filter of main body of dust collector.
In the system of day patent application No.2003-135336 of the present disclosure and H10-8519, eddy current produces in dust separating part, and dust is collected in by the dust that is contained in the funnel type bottom and collects in mouthful dust arrester that is separated.Therefore, the eddy current in the dust separating part does not trend towards entering dust arrester.Therefore, in dust arrester, the quantity of the dust of taking away by eddy current is compared and will be lacked with the system among the Japan Patent No.3102864.
Yet,, produce eddy current in the inner meeting of dust arrester, thereby take away dust according to amount of air drawn; Prevent safely that with regard to being difficult to the dust in the dust arrester is pulled away like this.Further, install, increased the total length of structure, the problem that causes an equipment size to increase because dust arrester is independent of dust separating part.
Summary of the invention
For above-mentioned reasons, first purpose of the present invention provides a kind of cyclone type dust separator, and it can prevent to take away by the dust that air-swirl will be deposited in dust collecting trough or the dust arrester.Discharging and these dusts of preventing the dust that is pulled away like this enter in the main body of dust collector.

Electric cleaner 10 is also available under the situation that does not have cyclone type dust separator 22; In this case, flexible pipe 18 (or front end of flexible pipe 18) and prolongation pipe 20 (or rear ends of prolongation pipe 20) are directly to be joined together to form suction line 16.When using cyclone type dust separator 22, cyclone type dust separator 22 is inserted in flexible pipe 18 and prolongs between the pipe 20.In other words, the rear end that the front end of flexible pipe 18 is connected to cyclone type dust separator 22 (or is connected on the blast pipe 32 of cyclone type dust separator 22, the back is introduced), the rear end of flexible pipe 18 is connected on the main body of dust collector 10, suck annex (absorbent brush) 24 and append to the front end that prolongs pipe 20, and the rear end that prolongs pipe 20 is connected to (or being connected on the air inlet pipe 34 of dust separator 22 the back introduction) on the dust separator 22, shown in the arrow among Fig. 1.
When opening, the electro-motor of blower fan is activated with the switch on the cyclone type dust separator 22 (not expression); In sucking annex 24, produce an air negative suction.Have dust air be inhaled into through sucking annex 24, the relatively large dust of particulate mass is separated from inhaled air by cyclone type dust separator 22; Air enters in the main body of dust collector 10 subsequently.Air is discharged to the outside through the main body of dust catcher and by blast pipe.
As shown in Figure 2, cyclone type dust separator 22 is by dust separating part 26, and dust storage chamber 28 and handle 30 constitute.
As shown in Figure 5, eddy current path 38 by partition wall 38a, be formed at the eddy current passage opening 38b among this partition wall 38a, the inclined wall 38c that constitutes the upper wall of eddy current path 38, circular arc periphery wall 38d, internal perisporium 38e around forming, wherein, partition wall 38a constitutes the lower wall of eddy current path 38 and minor air cell's 40 separations.Eddy current passage opening 38b forms by along the circumferential direction partition wall 38a being cut away length L.Internal perisporium 38e is formed by the outer peripheral face of blast pipe 32, the upstream side of inclined wall 38c (upstream side is the part that is positioned at suction line 34 1 sides) joins with the upper wall of suction line 34, and downstream (being positioned at the part of partition wall 38a one side) is connected with the trailing edge 38f (downstream of its potential vortex direction) of opening 38b.
On the circumferential wall of blast pipe 32, there is the exhaust outlet 42 (as shown in Figure 6) of some to make exhaust outlet 42 in the face of minor air cell 40.Each exhaust outlet 42 all is a slit, and its length along blast pipe 32 longitudinal directions is greater than width along the circumferential direction.Like this, for example, exhaust outlet 42 can have the long 6mm of nearly 20mm wide.These exhaust outlets 42 be located at along blast pipe longitudinally two sections go up (upper and lower), they can prevent that relatively large fragment such as similar paper scrap is inhaled in the blast pipe 32.The lower end 32a of blast pipe 32 is closed, and the baffle plate 44 that is roughly the taper extension is placed on this lower end of blast pipe 32.In the embodiment shown, baffle plate 44 has justifies (falling) taper substantially, thus its down edge diameter increase gradually.
By said structure, the air of air or band dust is inhaled into by suction annex (sucking brush) 24, and flows into prolongation pipe 20 rapidly, enters the suction line 34 of separator 22.Then, air enters eddy current path 38, flow along the periphery wall of bending and internal perisporium 38d and 38e, and meet inclined wall 38c, thereby air flows into minor air cell 40 downwards by eddy current passage opening 38b in rotation, form eddy current 36 or whirlwind like this.Eddy current 36, particularly be positioned near the air part in eddy current 36 centers, exhaust outlet 42 by blast pipe 32 enters blast pipe 32, thereby the dust that size is big in the air is partly blocked by the strip between each exhaust outlet 42 thereby separated from eddy current 36 and remove, and the air with the large scale dust flows into body of dust collector 10 by flexible pipe 18 at last.
The diameter of baffle plate 44 is set as and can allows to make air to flow between the inner surface of baffle plate 44 and dust storage chamber 28, has prevented that therefore eddy current 36 from flowing below baffle plate 44, and forms a gap that has suppressed the dust refluence.
The inner bottom surface 46 of dust storage chamber 28 is a curved surface, and its diameter evenly reduces on downward direction.In the inner bottom surface 46 of dust storage chamber 28, form the depressed part 48 of a sinking in the heart.Depressed part 48 is columnar, the bottom surface that a sealing is arranged, the diameter of depressed part 48 is about 1/2 to 1/3 of dust storage chamber 28 diameters, and more properly, the diameter of depressed part 48 is about dust storage chamber 28 reality at 1/2 to 1/3 of the diameter of the vertical middle body at the height place of baffle plate 44.As shown in Figure 3, the center line of depressed part 48 is located on the center line A of blast pipe 32, therefore is positioned on the rotating shaft of eddy current 36.
The curved surface of dust storage chamber 28 inner bottom surface 46 and be not continuously smooth (rough continuously) at the opening of depressed part 48 or near the inner surface the edge of opening 48a.In other words, as shown in Figure 3, the inner bottom surface 46 of dust storage chamber 28 and the opening of depressed part 48 or edge of opening 48a have formed the surface of obtuse angle shape or the surface of step like this with on the interconnected part of the form at obtuse angle.Because the bottom surface internally 46 that this connection surface is discontinuous form, boundary form or step to be constituted is to the bending of depressed part 48, even eddy current 36 reduces along inner bottom surface 46, this eddy current also can be subjected to the obstruction of the edge of opening 48a of depressed part 48, and the dust that has dropped in the depressed part 48 can not taken away by eddy current.Further, prevented that the dust that drops in the dust storage chamber 28 is pulled away, because these dusts that drop in the dust storage chamber 28 stir together with the dust that dropped into dust storage chamber 28 bottoms in the past.
