Following with reference to one of Fig. 1～Fig. 7 F detailed description the present invention embodiment.
Use ground of the present invention mobile model dust catcher as shown in Figure 1, constitute with inhalator 4 etc. by main body of dust collector 1, flexible pipe 2, tube connector 3 and ground.
In main body of dust collector 1, be provided with the dust storage chamber 9 of motor room 6 and use paper bag 7 and micronic filter 8, inhalant electric blowing machine 5 is housed in this motor room 6.
Again, be provided with exhaust outlet 11, a part of exhaust of electric blowing machine 5 is discharged to the outside through discharge filter 10 in the rear side of main body of dust collector 1.
And the part of main body of dust collector 1, flexible pipe 2, tube connector 3 and ground are to constitute like this with inhalator 4, and promptly stream is a duplex, is divided into air-breathing stream A and exhaust flow path B, is communicated with between each one.
Promptly, in the dust storage chamber 9 of main body of dust collector 1 and the lower side of motor room 6, be formed with the exhaust flow path B of a part of exhaust gas recirculation that is used to make electric blowing machine 5, this exhaust flow path B is communicated with the exhaust flow path B of hose transition 20, and the flexible pipe that this hose transition 20 is contained in main body of dust collector 1 inserts in the mouth 12.
Another distolateral end that the flexible pipe 2 of duplex is housed at this tube connector 20a, 20b.The same opaque flexible hose 2a of same use in washing machine drainpipe that is called the conduit flexible pipe is used in the inboard of this flexible pipe 2, the flexible hose 2b that the outside uses the general electric dust collector of the interior wiring astragal 21 that is called one deck two-wire flexible pipe to use, this winding wire 21 have electric conductivity (because of being used as holding wire etc.) and conformality.The inboard conduit flexible pipe 2a that uses is because in one deck two-wire pipe 2b outside considering winding wire 21 is housed, and the inboard cause that does not need winding wire.Conduit flexible pipe 2a is because of wiring astragal 21 in unlike one deck two-wire flexible pipe 2b, thus in light weight, and have stepped on also not by mistake can be as one deck two-wire flexible pipe 2b residual deformation and the advantage that can restore.About retractility, in the pipe that constitutes by polyvinyl chloride resin etc., adorned one deck two-wire pipe 2b of winding wire 21, than corrugated conduit flexible pipe 2a excellence with resin forming.Again, in the present embodiment, this one deck two-wire pipe 2b forms with translucent polyvinyl chloride resin etc.
So, be conceived to have only interior this advantage of wiring astragal of pipe of a side, translucent pipe is used in the outside, will with in the past have only the same one deck two-wire flexible pipe 2b of air-breathing pipe, the inboard conduit flexible pipe 2a that uses light weight, like this, handle with just the same originally with the distribution of hose grip portion 24 and main body of dust collector 1 with operation on hand described later, but 2 lightweights of dual flexible pipe.
Again, set foot under the situation of stating dual flexible pipe 2 in mistake, because of the conduit flexible pipe 2a of inboard not residual deformation restore, so as long as one deck two-wire flexible pipe 2b in the outside is indeformable, the conduit flexible pipe 2a of inboard can not be out of shape yet, if one deck two-wire flexible pipe 2b in outside distortion, the conduit flexible pipe 2a of inboard also can be out of shape, just can learn its state by seeing outside the dual flexible pipe 2, can prevent because of the bad phenomenon that the dust obstruction takes place unusually of inboard flexible pipe not to be noted.
Again, because of the good one deck two-wire flexible pipe 2b of retractility is located at the outside, so also can not lose flexibility during with 2 bendings of dual flexible pipe.
In addition, because of the conduit flexible pipe 2a of inboard opaque, one deck two-wire flexible pipe 2b in the outside is translucent, so can improve presentation quality by the improvement in the design, though dual flexible pipe 2 is thicker than general flexible pipe, but because of one deck two-wire flexible pipe 2b in the outside is translucent, thus the conduit flexible pipe 2a of inboard can be seen, so seem thinner.Again, because of inner conduit flexible pipe 2a that dust passed through opaque, outside one deck two-wire flexible pipe 2b that dust free pure air passes through after the dedusting is translucent, so cannot see the dust of the conduit flexible pipe 2a inner face that is attached to the inboard, and one deck two-wire flexible pipe 2b inner face in the outside does not pollute, so the outward appearance of dual flexible pipe 2 can be not influenced yet.Again, because of can seeing the state of inner conduit flexible pipe 2a from the outside, so, can prevent to take place bad phenomenon such as dust obstruction because of inboard flexible pipe not to be noted unusual with above-mentioned the same.
Above-mentioned flexible pipe 2, be conduit flexible pipe 2a with the inboard be contained in engage on the inboard tube connector 20a jag after, one deck two-wire flexible pipe 2b in the outside is screwed in the rib 22 again and installs and fixes, this rib 22 is to form on the outer surface of the tube connector 20b in the outside spirally shown in Fig. 4 A, Fig. 4 B.Cover the installation portion of this flexible pipe 2 with tubular over cap 23.
Above-mentioned, because of the comparison easy-on one deck two-wire flexible pipe 2b that only is positioned at the outside that is screwed into, the conduit flexible pipe 2a that is positioned at inboard difficulty installation directly inserts the back joint, so installation is simple.Again, more outstanding laterally because of this flexible pipe installation end when the conduit flexible pipe 2a of this inboard is installed than the flexible pipe installation end of the tube connector 20b in the outside, so the tube connector 20b in the outside can not hinder installation, can install with comparalive ease.Therefore, the assembling procedure of dual flexible pipe 2 is simpler.
Again, the other end of above-mentioned flexible pipe 2 is mounted on the handle portion 24 of operating usefulness on hand through tube connector 24a, 24b with above-mentioned the same.Promptly, with the conduit flexible pipe 2a of inboard be contained in engage on the inboard tube connector 24a jag after, one deck two-wire flexible pipe 2b in the outside is screwed in the rib 25 again and installs and fixes, this rib is formed on the outer surface of tube connector 24b in the outside in a spiral manner shown in Fig. 6 A, Fig. 6 B.Also cover the installation portion of this flexible pipe 2 with tubular over cap 26.
This situation is also with above-mentioned the same, and because of one deck two-wire flexible pipe 2b that has only the outside that is screwed into, the conduit flexible pipe 2a of inboard directly inserts the back to engage, so install simple.Again, more outstanding laterally because of this flexible pipe installation end when the conduit flexible pipe 2a of this inboard is installed than the flexible pipe installation end of the tube connector 24b in the outside, so outside tube connector 24b can not hinder installation, can install with comparalive ease.Therefore, the assembling procedure of dual flexible pipe 2 is simpler.
Again, above-mentioned handle portion 24 is to constitute like this, is about to be equipped with the air-breathing stream A of suction inlet 27 of connecting piece 3 and partition wall portion 28 that exhaust flow path B separates to inner recess both set a distance.On the top of this suction inlet 27, be provided with binding clasp 29 in order to install and fix connecting piece 3.
In addition, utilize figure to go up unshowned rib etc., interior outer connecting pipe 24a, the 24b of interior outer connecting pipe 20a, the 20b of above-mentioned hose transition 20 and above-mentioned handle portion 24 partly coupled together and form the duplex of concentric circles.
Connecting piece 3,3 is respectively shown in Fig. 7 A, Fig. 7 B, Fig. 7 C, Fig. 7 D, Fig. 7 E, Fig. 7 F, constitute by side cylindrical portion 3a within the air-breathing stream A of cross section approximate circle shape and the outside cylindrical portion 3b that forms exhaust flow path B, the top of this outside cylindrical portion 3b and inboard cylindrical portion 3a form one, and are covered with inboard cylindrical portion 3a.
Again, because of the exhaust by above-mentioned exhaust flow path B is the pure air of having removed dust through the paper bag 7 and the micronic filter 8 of main body of dust collector 1, form the sub-circular cross section so needn't as inboard cylindrical portion 3a, consider dust to block, be conceived to this point, in the present embodiment the cross section of exhaust flow path B is made approximate half moon-shapedly, sub-circular is made in the cross section of outside cylindrical portion 3b.
Thereby the incorporate part in top can corresponding weight reduction, also can reduce volume simultaneously, and because of inside and outside all be the sub-circular cross section, so can not reduce intensity, the operating characteristics excellence.Therefore, the connecting piece 3 of present embodiment is compared with the air-breathing pipe that has only in the past, does not have the difference sense, can obtain essentially identical shape and operating characteristics.
In addition, on the top of this connecting piece 3, and covering cable equally was installed in the past and was connected lid 32 with binding clasp 31.
Again, on this connecting piece 3, connecting a tube connector 3 again or connecting ground is formations like this with suction inlet 33 1 sides of inhalator 4, and partition wall portion (wall part within the inboard cylindrical portion 3a) 34 that promptly separates air-breathing stream A and exhaust flow path B is to inner recess both set a distance.
The other end of connecting piece 3, corresponding with suction inlet 33 sides of the suction inlet 27 of above-mentioned handle portion 24 or connecting piece 3, outside cylindrical portion 3b forms slightly little diameter, so that it is chimeric with the interior week of suction inlet 27,33 sides, and top is formed with the projection 35 that engages with binding clasp 29,31, till outside cylindrical portion 3b is embedded in binding clasp 29,31 and projection 35 engages, like this, make the end of inboard cylindrical portion 3a and recessed suction inlet 27,33 sides and opening ora terminalis 28a, the 34a fluid-tight engagement of the partition wall portion 28,34 that forms.
In addition, ground forms the duplex of concentric circles with junction block 4a, the 4b of inhalator 4, but with the part and the above-mentioned the same formation of above-mentioned connecting piece 3 tablings.
When use has the electric dust collector of said structure, utilize the suction of electric blowing machine 5, make the air that is mixed with the dust that ground sucked with inhalator 4, be inhaled in the main body of dust collector 1 by the air-breathing stream A of connecting piece 3, the air-breathing stream A of flexible pipe 2.In main body of dust collector 1, except that behind the dust, the air through micronic filter 8 cleaningizations is attracted by electric blowing machine 5 again with paper bag 7, and 5a cools off to its motor.
The part of the exhaust of electric blowing machine 5 is arranged to the outside from the exhaust outlet 11 of main body of dust collector 1, remainder is behind the exhaust flow path B of the exhaust flow path B of main body of dust collector 1, the exhaust flow path B that passes through flexible pipe 2, connecting piece 3, be recycled to the air-breathing stream A of connecting piece 3 earthward together with the dust that inhalator 4 refluxes and this exhaust wind is kicked up.
As noted above, the exhaust gas recirculation formula electric dust collector of present embodiment, because of can realizing that flexible pipe 2 lightweights that air-breathing stream A and exhaust flow path B are passed through and assembling procedure oversimplify, and the lightweight of connecting piece 3, miniaturization etc., so in practicality, can specifically bring into play the advantage of exhaust gas recirculation formula.
That is, by with a part of exhaust gas recirculation, make to blow to outside exhaust wind and reduce and die down, the dust in the time of just can suppressing to clear away effectively in the room is kicked up.
The air of circulation is repeatedly also arranged, thereby row is cleaner after the exhaust wind self of outside passes through paper bag 7 and micronic filter 8.Again, because of the flow velocity of the exhaust wind that blows out from exhaust outlet 11 has also reduced, so exhaust improves the exhaust gas purification better effects if with the filter efficiency of filter 10.This also meets environmental requirement in recent years.
Fig. 8～Figure 10 B is a structural map of representing additional embodiments of the present invention, and the part identical or suitable with the foregoing description used identical symbol.
As Fig. 8 and shown in Figure 9, present embodiment has the escapement 201 that auxiliary tube 200 reaches closely chimeric auxiliary tube 200, this auxiliary tube 200 is installed on the end that inboard flexible pipe is conduit flexible pipe 2a (handle portion 24 sides), and closely chimeric with the inboard flexible pipe installation end of the tube connector 24a of handle portion 24 sides.
This escapement 201 is shown in Fig. 9 and Figure 10 A, Figure 10 B, it is made of cannelure 203 that forms on fitting portion 202 peripheries of auxiliary tube 200 and C type ring element 205, has anti-drop function, this C type ring element 205 is contained in the installing hole 204 on the inboard flexible pipe installation end of tube connector 24a, fasten with the cannelure 203 of auxiliary tube fitting portion 202, and be contained within auxiliary tube 200 and the tube connector 24a on the conduit flexible pipe 2a side flexible pipe installation end with in a circumferential direction slidably mode be connected.
Above-mentioned C type ring element 205 is to install like this, after soon long side 206 sides of the side shown in Figure 10 B will be inserted in the embeded slots 203 from installing hole 204, again with opposite side because of breach 207 rubber-like pawls 208 are pressed in the installing hole 204, pawl 208 is with regard to the ora terminalis that hooks installing hole 204 and can not break away from.In addition, in Figure 10 B, label 24d be with interior outer connecting pipe 24a, 24b couples together and form the rib of concentric circles duplex.
The assembling procedure (step) of dual flexible pipe 2 that has carried out above-mentioned improved present embodiment is as described below.
At first, above-mentioned auxiliary tube 200 is contained on the end of conduit flexible pipe 2a of inboard and is joined together, and then with the other end of conduit flexible pipe 2a, on the tube connector 20a jag of the same inboard that is contained in the connecting portion 20 that inserts main body of dust collector 1 one sides with the foregoing description, be joined together, again one deck two-wire flexible pipe 2b in the outside be screwed in the rib 22 on the tube connector 20b outer surface in the outside and install and fix.Like this, the assembling of main body side connecting portion 20 has just been finished.
Then, with the above-mentioned auxiliary tube 200 that is contained on one of conduit flexible pipe 2a end, after the chimeric fluid-tight engagement of side flexible pipe installation end within the tube connector 24a, the 24b that are contained in the hose grip portion 24, more as described above, in the installing hole 204 on the inboard flexible pipe installation end of C type ring element 205 embeddings.Like this, conduit flexible pipe 2a just is slidably mounted on the tube connector 24a of inboard.One deck two-wire flexible pipe 2b in the outside is in the rib 25 on the same tube connector 24b outer surface that is screwed into the outside with the foregoing description and install and fix.
At this moment, another distolateral being fixed on the main body side connecting portion 20 because of dual flexible pipe 2, when former one deck two-wire flexible pipe 2b with the outside is screwed into, inboard conduit flexible pipe 2a also turns in the same direction, but in the present embodiment, as mentioned above, Gu conduit flexible pipe 2a be slidably mounted on the inboard tube connector 24a, so on conduit flexible pipe 2a, can not twist.
As mentioned above, according to present embodiment, the conduit flexible pipe 2a of inboard upward installs extremely simple toward tube connector 24a, nor can twist, so do not need to take the countermeasure in advance conduit flexible pipe 2a reversed to an opposite side because of considering to reverse, the assembling procedure of dual flexible pipe 2 is very simple.
In addition, in the above-described embodiments, handle portion 24 1 sides are that install the back, have taked above-mentioned countermeasure in handle portion 24 1 sides of conduit flexible pipe 2a, but under the situation of main body side connecting portion 20 1 rear flank installation, as long as take above-mentioned countermeasure in main body side connecting portion 20 1 examples of conduit flexible pipe 2a.Again, as mentioned above, only take above-mentioned countermeasure also can obtain good effect in a side of difficulty assembling, if all take above-mentioned countermeasure in both sides, then assembling procedure will be simpler.
Again, in the various embodiments described above, harness had one deck two-wire flexible pipe 2b of the winding wire 21 of electric conductivity and conformality in outside flexible pipe used, but the present invention does not limit to so, for example also can use the flexible pipe of the interior dress holding wire that is called two layer of four line flexible pipe and power line (brush with), or inner the not so good conductor wire of conformality (copper cash etc.) be housed and itself have the flexible pipe of conformality, or constitute by metal or synthetic resin, in the flexible pipe etc. of the coiled type member (conformal member) with conformality is housed.
Again, outside flexible pipe (one deck two-wire flexible pipe 2b) has adopted translucent, but no matter be translucent or transparent, as long as have the transparency, just can obtain and above-mentioned the same action effect.
As noted above, according to the present invention, flexible pipe is made duplex, and the outside flexible pipe that forms exhaust flow path uses the flexible hose of interior dress conductor wire, the inboard flexible pipe that forms air-breathing stream uses the inner flexible hose of not adorning conductor wire, like this, handle just fully with in the past the same with the distribution of hose grip portion of operating usefulness on hand and main body of dust collector, because of inboard flexible pipe is not adorned conductor wire, so the corresponding weight reduction of dual flexible pipe that air-breathing stream and exhaust flow path passed through, the just easy practicability of exhaust gas recirculation formula electric dust collector.Again, stepped under the situation of this dual flexible pipe in mistake, outside flexible pipe is because of the easy residual deformation of interior dress conductor wire, inboard flexible pipe is unkitted conductor wire because of inside and is not easy residual deformation, as long as outside flexible pipe is not out of shape, inboard flexible pipe can not be out of shape yet, if outside flexible pipe distortion, inboard flexible pipe also can be out of shape, and just knows its state by the outward appearance of dual flexible pipe, can prevent because of the unusual bad phenomenon that dust obstruction and so on takes place of inboard flexible pipe not to be noted.
Again, because of flexible pipe is a duplex, and the outside flexible pipe that forms exhaust flow path uses the flexible hose of interior dress conformal member, the inboard flexible pipe that forms air-breathing stream uses the inner flexible hose of not adorning the conformal member, because of being unkitted the conformal member in the inboard flexible pipe, so the dual flexible pipe that passed through of air-breathing stream and exhaust flow path can corresponding weight reduction, exhaust gas recirculation formula electric dust collector is practicability easily just.
Again, the inboard flexible pipe installation end of the tube connector of duplex is more outstanding laterally than outside flexible pipe installation end, so when being positioned at the inboard flexible pipe of inboard difficulty installation, because of the flexible pipe installation end of inboard tube connector is given prominence to laterally than the flexible pipe installation end of outside tube connector, so the installation exercise of inboard tube connector is not subjected to the interference of outside tube connector, installs easily.The assembling procedure of dual flexible pipe has become simply, and the tube connector of above-mentioned duplex is used for an end of the flexible pipe of duplex is contained in the flexible pipe insertion mouth of main body of dust collector, and the other end is contained in the hose grip portion.
Again, except be used for flexible pipe that a end with the flexible pipe of duplex is contained in main body of dust collector insert mouthful in, the other end is contained in the tube connector of the duplex in the hose grip portion, also have at least one end that is contained in inboard flexible pipe and with corresponding tube connector within the tight chimeric auxiliary tube of side flexible pipe installation end, and prevent the escapement that closely chimeric auxiliary tube is thrown off, make assembling extremely simple than the installation exercise of the inboard flexible pipe of difficulty.
In addition, above-mentioned escapement has at the cannelure that forms on the fitting portion periphery of this auxiliary tube and is contained on the inboard flexible pipe installation end of tube connector and the fastened component that engages with this cannelure, because of the auxiliary tube that is contained on the inboard flexible pipe is connected in the mode that can slide in a circumferential direction with the inboard flexible pipe installation end of tube connector, therefore, promptly use the mode of being screwed into that outside flexible pipe is installed, because of on inboard flexible pipe, not twisting yet, and do not need to take because of considering to reverse the countermeasure of in advance inboard flexible pipe being reversed to opposition side, the assembling procedure of dual flexible pipe is very simple.
Again, because of inboard flexible pipe is opaque, and outside flexible pipe has the transparency, so can improve presentation quality by improving design, though dual flexible pipe is thicker than general flexible pipe, but can see inboard flexible pipe because of seeing through the outside flexible pipe with transparency, so seem thinner.Again, the inboard flexible pipe that passes through because of dust is opaque, and the outside flexible pipe that the dust free pure air after the dedusting passes through is translucent, cannot see attached to the dust on the inboard flexible pipe inner face, and outside flexible pipe inner face does not pollute, so the outward appearance of dual flexible pipe can be not influenced yet.Because of can see the state of inboard flexible pipe from the outside, therefore, can prevent to take place bad phenomenon such as dust obstruction because of inboard flexible pipe not to be noted unusual again.
Again, because of pipe is to be formed one and be covered with the outside inboard cylindrical portion, that form exhaust flow path cylindrical portion by the inboard cylindrical portion of the air-breathing stream that forms the sub-circular cross section and a part and this inboard cylindrical portion to constitute, therefore, needn't worry that dust blocks, pipe lightweight, miniaturization that air-breathing stream and exhaust flow path passed through, the easier practicability of exhaust gas recirculation formula electric dust collector.
In addition, approximate half moon-shaped by the cross section of the exhaust flow path of pipe is made, sub-circular is made in the cross section of the outside cylindrical portion of pipe, like this, compare with the air-breathing pipe that has only in the past, do not have the difference sense, the electric dust collector that can be had the same shape and operating characteristics substantially.
