This inside tube 19 forms longer than outboard tube 18, makes to be contained in one of flexible pipe connector 5 and distolaterally to insert mouthful 9a from flexible pipe and give prominence to dust arrester 9 in.And another distolateral formation is longer than outboard tube 18, outer circumferential side form and the outer ribs 18b of outboard tube 18 towards the interior side rib 19b of equidirectional inclination.Label 20 is columnar lids of being arranged to cover a side that is connected with flexible pipe 21 of base side hose transition 17.
Base side hose transition 17 ends through flexible pipe connector 5 cards that will block claw stop 18a and body of dust collector 1, and the inside tube 19 of base side hose transition 17 is given prominence in dust storage chamber 9 also and connection in the dust storage chamber 9, becomes air-breathing stream A2 in the inside tube 19.Again, the exhaust flow path B1 in outboard tube 18 and the body of dust collector 1 is communicated with, and becomes exhaust flow path B2 between outboard tube 18 and the inside tube 19.
Label 21 is the flexible pipes that are contained in base side hose transition 17 and hose transition described later 27, as shown in Figure 5, and the duplex that serve as reasons outside flexible pipe 22 and inboard flexible pipe 23 constitute.
This outside flexible pipe 22 as shown in Figure 6, the member that member through the length that will be made of the polystyrene synthetic rubber is wound into helical form, use the bonding length of bonding agent that is made of polypropylene forms tubulose at the adhesive portion 22a of width end, at the spiral helicine prominent bar 22b of each self-forming of about central portion, the 22c of the width of this adhesive portion 22a and long member.And, in this prominent bar 22b, 22c, pretend coil 22d, 22e into the electric conductivity of holding wire, utilize the intensity of this coil 22d, 22e order outside flexible pipe 22 to improve.In addition, this outside flexible pipe 22 forms translucent.
And, inboard flexible pipe 23 as shown in Figure 7, same with outside flexible pipe 22, member through the length that will be made of the polystyrene synthetic rubber is wound into helical form, the member of using the bonding length of bonding agent that is made of polypropylene is at the adhesive portion 23a of width end and form tubulose, the spiral helicine prominent bar 23b of each self-forming of about central portion place at the width of this adhesive portion 23a and long member, 23c, the width of member that constitutes the length of this inboard flexible pipe 23 is formed narrower than the width of the member of the length that constitutes outside flexible pipe 22, with the prominent bar 23b of inboard flexible pipe 23, the spacing of 23c forms the prominent bar 22b than outside flexible pipe 22, the spacing of 22c is narrow.Again, inboard flexible pipe 23 can be seen inboard flexible pipe 23 textural opaque through forming at polystyrene synthetic rubber interpolation colouring agent by outside flexible pipe 22.
Side rib 19b in this flexible pipe 21 at first is made as the coiling direction of inboard flexible pipe 23 with the inclination of the interior side rib 19b of base side hose transition 17 and inboard flexible pipe 23 is screwed into after equidirectional.At this moment, distolateral more outstanding than outboard tube 18 because of the connection flexible pipe 21 of inside tube 19 so can and install inboard flexible pipe 23 these ledges of insertion, can easily be installed inboard flexible pipe 23.
Secondly, the same with the situation of inboard flexible pipe 23, the coiling direction of outside flexible pipe 22 is made as with the inclination of the outer ribs 18b of base side hose transition 17 outside flexible pipe 22 is screwed into outer ribs 18b after equidirectional, finish the installation of 21 pairs of base side hose transitions 17 of flexible pipe.
At this moment, in the inboard flexible pipe 23 and the air-breathing stream A2 of base side hose transition 17 be communicated with, become air-breathing stream A3, and between outside flexible pipe 22 and the inboard flexible pipe 23 and the exhaust flow path B2 of base side hose transition 17 be communicated with, become exhaust flow path B3.
Again, because of the coiling direction with the coiling direction of inboard flexible pipe 23 and outside flexible pipe 22 be made as equidirectional, so the flexible direction of inboard flexible pipe 23 and outside flexible pipe 22 or easily torsional direction become equidirectional.Therefore, flexible pipe 21 reverses or when crooked in body of dust collector 1 uses, because of outside flexible pipe 22 and inboard flexible pipe 23 reverses mutually with following the trail of or crooked, thus outside flexible pipe 22 and inboard flexible pipe 23 for separately reverse or bending can not become resistance each other, guaranteed the flexibility of flexible pipe 21.
Label 24 is that at one end side connects flexible pipe 21, and in the portion of holding of another distolateral installation connecting piece 32 described later, by the handle portion 35 that connecting piece 32 is installed, and at one end side connects flexible pipe 21, and another distolateral hose transition 27 that is contained in handle portion 35 constitutes.
Hose transition 27 adopts by columnar outboard tube 28 and with ribs 29a and the duplex that these outboard tube 28 integrally formed inside tube 29 constitute, and is provided with and covers 31, to cover a side that connects flexible pipe 21.
The outer ribs 18b of each self-forming of periphery of this outboard tube 28 and inside tube 29 and base side hose transition 17 and in the same outer ribs 28a that tilts of side rib 19b and in side rib 29a, can be with the outside flexible pipe 22 of flexible pipe 21 and inboard flexible pipe 23 towards equidirectional stubborn and install.Thereby assembling operation is easy.
At this moment, the exhaust flow path B3 with flexible pipe 21 between outboard tube 28 and the inside tube 29 is communicated with, and becomes exhaust flow path B4.Again, the air-breathing stream A3 connection in the inside tube 29 and in the flexible pipe 21 becomes air-breathing stream A4.
Described handle portion 35 is made of the tube 25 of ヘ font and the handle 26 that extends above tube 25, forms the installing port 25a that connecting piece 32 is installed, and folder 25b is set on the top of installing port 25a.Again, be communicated with at inner and installing port 25a, form the cylindrical portion 30 of the end of inserting inside tube 29,30 air-breathing stream A4 interior and inside tube 29 are communicated with cylindrical portion, become air-breathing stream A5, and with the outside of cylindrical portion 30 with hold between the periphery of portion 24 and be communicated with, as exhaust flow path B5 with the exhaust flow path B4 that forms by inside tube 29 and outboard tube 28.
Label 32 is and presss from both sides the connecting piece that the 25b card ends and be contained in the installing port 25a of the portion of holding 24, forms through linking 2 pipe 32a.This connecting piece 32 constitutes by the outside cylindrical portion 32b of cross section approximate circle shape with the integrally formed inboard cylindrical portion 32c of this outside cylindrical portion 32b off-centre and top and outside cylindrical portion 32b, and outside cylindrical portion 32b and inboard cylindrical portion 32c form half moon-shaped space.And, when this connecting piece 32 was contained in the portion 24 of holding, inboard cylindrical portion 32c and the air-breathing stream A5 that holds portion 24 were communicated with, and form air-breathing stream A6 in inside, and be communicated with the exhaust flow path B5 of the portion of holding 24 between outside cylindrical portion 32b and the inboard cylindrical portion 32c, form exhaust flow path B6.
Again, because of the exhaust by exhaust flow path B6 be via the dust bag 10 of body of dust collector 1 or micronic filter 12 filterings the air of cleaning of dust, so be conceived to and form cross section approximate circle shape this point as considering lint stoppage as the inboard cylindrical portion 32c, in the present embodiment, that this exhaust flow path B6 is made as the cross section is approximate crescent as above-mentioned, and cylindrical portion 32b forms cross section approximate circle shape with the outside.
Label 33 is the suction fittings that are connected with connecting piece 32, and tube connector 33a, the 33b that is connected with connecting piece 32 forms the duplex of concentric circles, adopts the shape the same with connecting piece 32 with the telescoping part of this connecting piece 32.
And, when using as constituted above electric dust collector, through the suction of electric fan 14, the mixing that sucks from suction fitting 33 air-breathing stream A5, the air-breathing stream A3 of flexible pipe 21 of air by connecting piece 32 of dust, be inhaled in the body of dust collector 1.In body of dust collector 1, with dust bag 10 filtering dust, the air via micronic filter 12 cleaningizations is sucked by electric fan 14 again, cools off this electric fan 14.
And, to discharge to the outside from the exhaust outlet 6 of a part of self-priming dirt device body 1 of the exhaust of electric fan 14, other are from the exhaust flow path B1 of the body of dust collector 1 exhaust flow path B3 by flexible pipe 21.At this moment, because of the direction of the prominent bar 23 of the direction of prominent bar 22b, the 22c of outside flexible pipe 22 and inboard flexible pipe 23 forms equidirectional, so prominent bar 23 caused air permeance resistance for flow air between outside flexible pipe 22 and inboard flexible pipe 23 reduce, and can be suppressed at the interior loss of exhaust flow path B3 of flexible pipe 21.
Constitute prominent bar 22b, the 22c of member of length of outside flexible pipe 22 and prominent bar 23b, the 23c of member that constitutes the length of inboard flexible pipe 23 because of order and form different spacings, so can not damage flexibility, operability can not reduce.
Promptly, during curved spout 21, even the prominent bar 23b of for example inboard flexible pipe 23 is clipped between the prominent bar 22b and prominent bar 22c of outside flexible pipe 22, also because of the prominent bar 22b of outside flexible pipe 22, the prominent bar 23b of the spacing of 22c and inboard flexible pipe 23, the spacing difference of 23c, so near the prominent bar 23b prominent bar 23c adjacent with the prominent bar 23b that is pressed from both sides or the prominent bar 23b that is pressed from both sides is difficult to be sandwiched between the prominent bar 22b and prominent bar 22c of outside flexible pipe 22, therefore, can prevent the prominent bar 23b of inboard flexible pipe 23,23c is sandwiched in the prominent bar 22b of outside flexible pipe 22 continuously, between the 22c, so the curvature of outside flexible pipe 22 can not become greatly, can not damage the flexibility of flexible pipe 21.
Each flexible pipe 22,23 through prominent bar 22b, between 22c and prominent bar 23b, be out of shape and bending between 23c, but constituting each flexible pipe 22, under the identical situation of the thickness of the member of 23 length, between till the adjacent prominent bar contact between prominent bar between every narrow, flexible pipe is flexible, it is good that operability becomes, and in the present embodiment, because of prominent bar 23b with inboard flexible pipe 23, the spacing of 23c forms the prominent bar 22b than outside flexible pipe 22, the spacing of 22c is narrow, so compare with outside flexible pipe 22, inboard flexible pipe 23 is flexible, when making flexible pipe 21 bendings, situation available and that only constitute flexible pipe by outside flexible pipe makes hose bending with the operating physical force of degree, compare with the operability of existing flexible pipe, can make operability reduce hardly, flexible pipe 21 can adopt duplex.
Again, with the inside of inboard flexible pipe 23 as air-breathing stream and the situation etc. of having glued thin things such as paper or cloth at suction fitting 33 down, the vacuums in the inboard flexible pipe 23 rise, and have only inboard flexible pipe 23 to shrink.Follow the contraction of inboard flexible pipe 23, the deformation of member of the length between adjacent prominent bar 23b, 23c, along with long deformation of members becomes big, long member will recover the power grow of original form, and becoming is difficult to shrink.Therefore, if the spacing of prominent bar is little, then the amount of contraction of flexible pipe is smaller, and long deformation of members amount will become greatly, is difficult to shrink, so compare with the wide situation of the spacing of prominent bar, can suppress amount of contraction less.
In the present embodiment, because of forming the prominent bar 23b of inboard flexible pipe 23, the spacing of 23c narrow, so the amount of contraction of inboard flexible pipe 23 can be suppressed for little, can reduce and have only inboard flexible pipe 23 to shrink big caused load outside flexible pipe 22, can improve the persistence of flexible pipe 21.
And behind the exhaust flow path B3 by flexible pipe 21, by the exhaust flow path B6 of connecting piece 32, the dust that refluxes and kick up because of this exhaust wind to suction fitting 33 circulates to the air-breathing stream A6 of connecting piece 32 together again.
Through as an above-mentioned part that makes exhaust reflux, die down because of the exhaust wind that blows out to the outside reduces, kick up so can be suppressed in the cleaning dust in room effectively.
In addition, in the above-described embodiments, the spacing of prominent bar 23b, the 23c of inboard flexible pipe 23 is formed narrower than the spacing of prominent bar 22b, the 22c of outside flexible pipe 22, but as shown in Figure 9, the spacing of prominent bar 22b, the 22c of outside flexible pipe 22 is formed than the spacing of prominent bar 23b, the 23c of inboard flexible pipe 23 is narrow and also can.
In this structure, the same with the foregoing description, even when curved spout 21, the somewhere of prominent bar 23b, the 23c of inboard flexible pipe 23 is sandwiched between prominent bar 22b, the 22c of outside flexible pipe 22, near the prominent bar of prominent bar 23b, the 23c that is pressed from both sides can not be sandwiched between prominent bar 22b, the 22c of outside flexible pipe 22 yet, the curvature of outside flexible pipe 22 can not become greatly, can not damage flexibility, and operability can not reduce.
Again, in this structure, because of making outside flexible pipe 22 flexible, so when carrying out the smaller bending operation of the not too crooked degree of inboard flexible pipe 23, can easily make flexible pipe 21 bendings with little power, compare with the operability of existing flexible pipe, can make operability reduce hardly, flexible pipe 21 can adopt duplex.
If according to a first aspect of the present invention, because of the winding spacing of the member of the length of flexible pipe outside the order formation Different with the winding spacing of the member of the length that consists of inboard flexible pipe, so outside the adhesive portion of inboard flexible pipe enters Position between the adhesive portion of the member of the length of side flexible pipe can not recur, and has to prevent that flexible pipe is difficult to Crooked, raising operability texts.
If according to a second aspect of the present invention, because of the winding spacing of the member of the length that will consist of inboard flexible pipe Form littler than the winding spacing of the member of the length that consists of outside flexible pipe, so the adhesive portion of inboard flexible pipe is advanced Position outside entering between the adhesive portion of the member of the length of flexible pipe can not recur, and has to prevent the flexible pipe difficulty Crooked, improve the operability texts, and become more flexible and existing soft through inboard flexible pipe Pipe is compared, and the flexible pipe texts that can make operability consist of hardly duplex is arranged with reducing.
