In the bottom surface (dorsal surface) of bottom 133, possess depressed part 159 in the side, catheter body portion 4 of main body of dust collector 1, become the shape that the dust collect plant fixed projection 117 of main body of dust collector 1 is chimeric with the depressed part 159 of bottom 133 bottom surface.During as it has been described above, install dust collect plant 12 on main body of dust collector 1, the depressed part 159 making bottom 133 bottom surface is chimeric with the dust collect plant fixed projection 117 of main body of dust collector 1, is pushed to main body of dust collector 1 side by dust collect plant 12 with jut for starting point.Then, utilizing the D locking press button 119 on above-mentioned upper cover 132 top, dust collect plant 12 is integrally forming with main body of dust collector 1.Therefore, if being arranged on main body of dust collector 1 by dust collect plant 12, then lid locking mechanism 150 is hidden in main body of dust collector 1 side.This is because, in the case of lid locking mechanism 150 is arranged on opposition side (outside), likely releases lid locking mechanism 150 when sweeping, be used for preventing misoperation.Such as, when sweeping the lower section of sofa or bed when rod-type etc., sometimes make main body of dust collector 1 the most close relative to floor, now, in the case of lid locking mechanism 150 is arranged on rear, contact with floor and lid locking mechanism 150 is likely released from.The position of lid locking mechanism 150 and hinge 158 is not limited to this, it is also possible to arrange in left and right relative to main body of dust collector 1.By arranging in left and right, it is possible to prevent above-mentioned misoperation, and hinge 158 does not highlights, therefore, it is possible to the height in direction before and after reducing main body of dust collector 1, it is possible to realize densification.

It addition, the central authorities of the bottom 133 of plate-like, possesses the depressed part 170 from prominent portion concave in central authorities.Additionally, the radius of a ball of depressed part 170 ball shape more than the bottom surface 140a of above-mentioned cylinder 140, the degree of depth of depressed part 170 is set to be formed without horizontal plane at depressed part 170 under the state (relative to the state of plane perpendicular of urceolus 128) opening bottom 133.It addition, depressed part 170 is set to shallower as far as possible so that when discharging rubbish, dust does not ends up at depressed part 170.

In present embodiment example, depressed part 170 split is formed, and in order to reduce because of the abrasion of parts during bottom 133 opening and closing and caused by the friction of cylinder 140, employs the materials such as POM (polyformaldehyde) but it also may integrally formed.

In the structure of urceolus 128 as above and inner core 129, by installing inner core 129 at urceolus 128, the slide mechanism being arranged at inner core 129 is carried out by being arranged at the opening and closing of the bottom 133 of urceolus 128 bottom.When opening bottom 133, umbrella portion 139 highlights downwards, if closing bottom 133, spring 145 shrinks, and umbrella portion 139 is accommodated in the cylinder 129b of bottom.Thus, if release the lid locking mechanism 150 of bottom 133 when throwing away rubbish, then umbrella portion 139 bloats downwards and releases dust.

＜ throws away action ＞ during rubbish

In the slide mechanism that urceolus 128 as above, inner core 129, rubbish are discharged, action during rubbish is thrown away in use Figure 21 and Figure 22 explanation.Figure 21 represents the E-E sectional view shown in Figure 11 of state closing bottom 133, and Figure 22 represents and discharges after rubbish (opening the state of bottom 133) in figure 21.

Bottom 133 is arranged at the button 154 of the lid locking mechanism 150 of dust collect plant 12 side and is released from by pressing.Bottom 133 possesses hinge 158 in the opposition side of lid locking mechanism 150, rotates with rotary shaft 158a of hinge 158 for axle, and bottom 133 becomes substantially vertical (upper surface of bottom 133 is vertical) state.

While bottom 133 is opened, by spring 145, umbrella portion 139 and cylinder 140 bloat downwards.Thus, compared with the state that bottom 133 is closed, when bottom 133 is opened, umbrella portion 139 is located closer to the position of the opening of the lower surface of urceolus 128.By the slip in this umbrella portion 139, the dust of trapping is released downwards.

After throwing away rubbish, when closing bottom 133, the bottom surface 140a of the cylinder 140 bloated downwards contacts with the depressed part 170 of the central authorities being arranged at bottom 133, and umbrella portion 139 and cylinder 140 are pushed upward.The bottom surface 140a of cylinder 140 contacts with spherical with depressed part 170, even if therefore by the action of closedown bottom 133, the angle of bottom 133 changes, it also is able to keep the bottom surface 140a of cylinder 140 constant with the contact area of depressed part 170, and, by making curved surface contact with each other, the most vertically exert a force, in therefore umbrella portion 139 is successfully accommodated in bottom cylinder 129b.Bottom 133 be not provided with depressed part 170 and with plane contact in the case of, the direction of force is vertical relative to plane, and therefore umbrella portion 139 is difficult in return to vertically, and bottom 133 is difficult to close.And, if closing bottom 133 to substantially horizontal, then hook part 156 contacts with claw 155, locked when utilizing the sealing member 157 being arranged at bottom 133 to keep airtight.

Additionally, possesses the mechanism so discharging dust from the lower section of dust collect plant 12, effective to the electric dust collector 100 (charging electric dust cleaner) possessing body terminal portion 9 as present embodiment example above dust collect plant 12, dust can be suppressed to be attached to (upper cover 132 side) above dust collect plant 12, it is prevented from dust and is attached to body terminal portion 9, thus the safest.

Hereinafter, to the upstream side as dust collect plant 12 import, to dust collect plant 12, the shape of ingress pipe 160 of air comprising dust and the flowing of structure, air illustrates.

＜ ingress pipe 160 ＞

The rod-type of present embodiment example, the electric dust collector 100 of portable two-purpose, possess ingress pipe 160, and ingress pipe 160 is the stream that the suction inlet 15 from the leading section of main body of dust collector 1 arrives the inflow entrance 149 of dust collect plant 12 (urceolus 128).Figure 23 is to omit each parts from the state being mounted with dust collect plant 12 at the main body of dust collector 1 shown in Fig. 5, and only represents ingress pipe 160 and the figure of dust collect plant 12.Figure 24 is the front view of Figure 23, and Figure 25 is the F-F sectional view shown in Figure 24.

The upper and lower opening of ingress pipe 160, and possess above-mentioned suction inlet 15 in lower section, possesses in the way of flow-through fluid the ingress pipe outlet 161 that the inflow entrance 149 with dust collect plant 12 (urceolus 128) is connected up.Suction inlet 15 in lower section connects sucking mouth 3 etc..

It addition, ingress pipe 160 is arranged on the side of dust collect plant 12.Viewed from above, the central shaft (NI) of the dust collect plant 12 shown in Figure 24 and the central shaft (not shown) of main body of dust collector 1 are positioned at (almost parallel) on same line.It addition, as it has been described above, dust collect plant 12 is arranged on the rear of main body of dust collector 1.The central shaft (HO) of the line part (straight line pipe arrangement 160a) of ingress pipe 160 is almost parallel with the central shaft of dust collect plant 12 (NI).The straight line pipe arrangement 160a of ingress pipe 160 has from the inflow entrance 149 of urceolus 128 length to the bottom of urceolus 128, in order to avoid bottom 133, arrange oriented towards bottom 133 central authorities direction bending after, further towards lower section extend straight line pipe arrangement 160b.Viewed from above, the central shaft (HE) of straight line pipe arrangement 160b and the central shaft (NI) of dust collect plant 12 are positioned on same line.In other words, ingress pipe 160 is following piping shape, i.e. the central shaft (HE axle) of the straight line pipe arrangement 160b that the central shaft of straight line pipe arrangement 160a and suction inlet 102 are had is almost parallel, and is connected below tilting by two straight line pipe arrangements.The angle of inclination of the inclination pipe arrangement 160c being connected below tilting by two straight line pipe arrangements is different according to the position of suction inlet 15, and the position (scope) being formed as suction inlet 15 is positioned at the shape of dust collect plant 12 bottom surface (bottom 133 external diameter).It addition, ingress pipe 160 is accommodated in the ingress pipe housing section 14 of main body of dust collector 1, the shape (right side shown in Fig. 1) that ingress pipe housing section 14 is heaved from the left side that forward observation is conductive pipe housing section 4.

In the ingress pipe outlet 161 being connected with the inflow entrance 149 of dust collect plant 12, possessing sealing member 162, if dust collect plant 12 is arranged on main body of dust collector 1, then sealing member 162 is crimped with inflow entrance 149 and keeps airtight.Sealing member 162 uses the parts of rubber, the spongiform parts without aeration or elastomeric material etc., carry out and the ingress pipe shapings (secondary forming) that are integrally forming of outlet 161 or sandwich between ingress pipe outlet 161 and ingress pipe housing section 14 and fixing etc., be formed as maintaining the airtight structure of ingress pipe outlet 161 and sealing member 162.Additionally, sealing member 162 can also be not arranged in ingress pipe outlet 161, and it is provided in the inflow entrance 149 of dust collect plant 12, but when being set to wash by dust collect plant 12, likely forget sealing member 162 etc. is installed in the case of sealing member 162 is for other parts, be arranged on ingress pipe outlet 161 the most preferably as described above.

As present embodiment example, the flowing of the air comprising dust caused making ingress pipe 160 bend represents in Figure 24, Figure 25 and Figure 26.Shown in figure 170 are dust, and the flowing of air is indicated by the arrow A.From the air of suction inlet 15 suction, the shape along ingress pipe 160 flows as shown by arrow A.Now, big with air phase specific density and have ponderable dust 170 and be pushed on the right side of the internal face of straight line pipe arrangement 160a with inertia force 180 by tilting pipe arrangement 160c, on the right side of internal face, it is moved to dust collect plant 12.Being connected with on the right side of the internal face of the inflow entrance 149 being arranged at urceolus 128 on the right side of the internal face of straight line pipe arrangement 160a, therefore the internal face with urceolus 128 is connected in substantially tangential direction.Thus, on the right side of the internal face of straight line pipe arrangement 160a, the dust 170 of carrying circles round near farthest urceolus 128 internal face in the outside diameter from the dust separated part 134 i.e. periphery of inner core 129, and therefore centrifugation performance improves.Additionally, according to the figure observed from suction inlet 15 side (lower section) shown in Figure 25 or Figure 26, straight line pipe arrangement 160a is positioned at than the position closer to the front for straight line pipe arrangement 160b with suction inlet 15, therefore in the same manner as above-mentioned flowing, dust 170 is carried on front side of the internal face of straight line pipe arrangement 160a with inertia force 180, therefore the top carrying of the inflow entrance 149 that dust 170 is possessed from urceolus 128.Thereby, it is possible to effectively use the short transverse of inflow entrance 149, therefore, it is possible to effectively use the height of dust separated part 134.Dust separated part 134 the highest (the longest) and the centrifugation performance of dust is the highest.Thus, by being set to the ingress pipe 160 of bending as present embodiment example, using the teaching of the invention it is possible to provide the height (densification) with suppression dust separated part 134 and the electric dust collector 100 of the dust collect plant 12 guaranteeing centrifugation performance.

It addition, arrange bending section at ingress pipe 160, then additionally aid the densification of main body of dust collector 1.Such as, in the mode of rod-type, when sweeping the lower section of sofa or bed, make main body of dust collector 1 near floor, carry out putting into the action of sucking mouth 3 in the narrowest gap.Now, such as shown in Japanese Unexamined Patent Publication 2002-85297 publication, if the shape that ingress pipe 160 extends as the crow flies, then dust collect plant 12 collides with bed, main body of dust collector 1 just cannot be made near floor if the most not lengthening ingress pipe 160.Thus, by making ingress pipe 160 bend as present embodiment example, it is possible to shorten length before and after main body of dust collector 1, using the teaching of the invention it is possible to provide compact electric dust collector 100.As the method for length before and after shortening main body of dust collector 1, ingress pipe 160 can be made too much to elongate and close floor by reducing the diameter of dust collect plant 12, if but reducing the diameter of dust collect plant 12, then the separating property of dust, the collection reduction of dust quantity, the pressure loss are also possible to deteriorate.By making ingress pipe 160 bend as present embodiment example, it is possible to be set to improve the separating property of dust, the collection dust collect plant 12 that dust quantity is many and the pressure loss is low, and compact electric dust collector 100 can be provided.

Additionally, even the shape that ingress pipe 160 extends as the crow flies, if with the electric dust collector 100 of present embodiment example differently, dust collect plant 12 is arranged on the front (front, rear in catheter body portion 4) of main body of dust collector 1, above-mentioned main body of dust collector 1 then can be made near floor, carry out putting into the action (with reference to Japanese Unexamined Patent Publication 2004-24887 publication) of sucking mouth 3 in narrow gap.But, if dust collect plant 12 to be arranged on the front of main body of dust collector 1, then the inflow entrance 149 of dust collect plant 12 is towards rear, therefore make main body of dust collector 1 near floor carry out sweep, the posture of main body of dust collector 1 is dust collect plant 12 under portable state top (catching dirt filter 130 side) is downward sweeps, when shutting down, dust likely remains in ingress pipe 160.In order to solve this problem, it is also contemplated that arrange check-valves at inflow entrance 149, but it is also possible to the increase of the pressure loss, dust that generation causes because of check-valves are sandwiched in the situations such as check-valves.Thus, as present embodiment example, dust collect plant 12 is arranged on the rear of main body of dust collector 1, ingress pipe 160 is made to bend, even if thus sweeping under posture various, dust is also difficult to remain in inflow entrance 149 side, therefore, it is possible to the increase of the pressure loss that causes because arranging check-valves etc. of suppression, dust are sandwiched in the situation of check-valves etc., and can provide compact electric dust collector 100.

If it addition, as it has been described above, from forward observation main body of dust collector 1, then ingress pipe housing section 14 becomes the shape (for the right side in catheter body portion in Fig. 1 etc.) heaved in the left side of conductive pipe housing section 4.Figure 27 represents the G-G sectional view of the main body of dust collector 1 shown in Fig. 6.As it can be seen, the central axis of dust collect plant 12 and main body of dust collector 1 is not positioned on the same line of two axles in almost parallel (on same line), the axle of the straight line pipe arrangement 160a of ingress pipe 160.So, by being staggered in the lateral direction from main body of dust collector 1 (dust collect plant 12) and be configured to left and right asymmetric (asymmetric) by ingress pipe 160, main body of dust collector 1 is difficult to the health collision with user.Figure 29, Figure 30 represent the figure from forward observation electric dust collector 100.Figure 29 is the electric dust collector 100 of the state of elongation telescoping catheter 5 and non-swing handle 2.Figure 30 is the electric dust collector 100 of contraction telescoping catheter 5 and the state that have rotated handle 2.It addition, by the ingress pipe housing section 14 in housing body 50 is set to the shape according to ingress pipe 160 shape such that it is able to realize the lightweight of light-weighted main body of dust collector 1 based on housing body 50.Thus, compared with symmetrical outward appearance, it is possible to reduce the outward appearance of main body of dust collector 1.In other words, if from forward observation main body of dust collector 1, then housing body 50 heaves the amount suitable with ingress pipe housing section 14 to the left, and housing body 50 is the shape of left and right asymmetric (asymmetric).That is, electric dust collector 100 entirety is also the shape of left and right asymmetric (asymmetric).

And, as present embodiment example, in the past direction is observed and in the case of left side configuration ingress pipe 160, the ledge in the left side of main body of dust collector 1 is few, and therefore right-handed person user easily uses, in the case of right side configuration ingress pipe 160, left hander user easily use.Urceolus 128, ingress pipe 160 and ingress pipe housing section 14 are only changed in right side, the switching in left side, therefore, it is possible to provide the electric dust collector 100 realizing general pattern with less part replacement.

Use Figure 28 illustrate as above by urceolus 128, inner core 129, catch dirt filter 130, the flowing of air under state that dust collect plant 12 that upper cover 132, bottom 133 are combined is arranged on main body of dust collector 1.Figure 28 represents the flowing of the air under portable state, the most identical when rod-type, therefore omits the flowing of the air of rod-type.

Utilize the operation button 11b being arranged at handle 2 to be proceeded by operating by user, then electric blower 17 drives and sucks air.The air sucked exports 161 from the suction inlet 15 of ingress pipe 160 through ingress pipe, in inflow entrance 149 inflow dust collection device 12 (flowing 200).Now, by the bending section of ingress pipe 160, while dust is pushed on the left of the internal face to ingress pipe 160, carry from the substantially tangential direction of urceolus 128 in dust collect plant 12.The air comprising dust flowed into becomes swirling flow, and to dust effect centrifugal force, dust is separated (flowing 201) with air.That is, with dust separated part 134 dirt separation and air.Most of air after separation flows into the inside of inner core 129 (flowing 202) from the air inlet 129c being arranged at top cylinder 129a.Then, air is through catching dirt filter 130, through the upper opening of upper cover 132, arrives electric blower 17 (flowing 203).Now, the fine dust of the mesh members 136 that have passed through air inlet 129c dirt filter 130 of being caught traps.

On the other hand, by the dust of centrifugal force separate by the air stream of gravity and a part between urceolus 128 and bottom cylinder 129b, be moved in dust receiving portion 135.Now, dust effect there is centrifugal force, therefore circle round in dust receiving portion 135 (flowing 204).Then, if being continuing with vacuum cleaner, then dust is gradually piled up and state that dust receiving portion 135 is filled becomes the moment throwing away rubbish.Air in inflow dust receiving portion 135 is along cylinder 140, the space 139a shape in umbrella portion 139, to top cylinder 129a effluent dynamic (flowing 205) near the periphery of bottom cylinder 129b.In order to suppress the flowing of this air causes, dust return top cylinder 129a side, umbrella portion 139 is needed to have the degree of depth.In present embodiment example, it is provided with the slide mechanism releasing dust at bottom cylinder 129b, therefore umbrella portion 139 is provided with enough degree of depth.It addition, utilize the dust of the tapered portion upper end being arranged at urceolus 128 to return to prevent face 151, suppression dust returns to top cylinder 129a side further.

After dust receiving portion 135 is full of by dust, throwing away rubbish, rubbish output mechanism is as it has been described above, in the case of the amount of the dust attracted is less, it is also possible to utilize the roughly conical shape of the slide mechanism in umbrella portion 139 and urceolus 128 to discharge dust.

Above, according to as present embodiment example as rod-type and the portable electric dust collector of dust collect plant that can use and possess the cyclone type being able to maintain that captivation, using the teaching of the invention it is possible to provide have both the electric dust collector easy to use of the intensity of small-size light-weight and captivation.
