As shown in Fig. 4～10, the dust of present embodiment accumulates unit 50 and mainly possesses reservoir 51, cap 53, brushes 55, brush cleaning portion 57, hinge connect mechanism 59 and sliding locking mechanism 62.

(2-1) reservoir

As shown in Fig. 5～8, reservoir 51 is extended along the length direction of the shell 11 of indoor set 100 (left and right directions, be W direction).Reservoir 51 has the shape (with reference to Fig. 7,8) that is downward convex, to can accumulate the dust removed from filter 31 and from brushing 55 dust of removing.And, at the upside of reservoir 51, be formed with and the dust of reservoir 51 inside can be discharged to outside peristome 52.

According to such reservoir 51, when the action that user carries out the dust of reservoir 51 inside to outwell, by making peristome 52 sides downward, thereby needn't directly contacting dust with hand, user just can the dust in reservoir 51 be outwelled through peristome 52.

In addition, according to disposing the size of shell 11 inside of indoor set 100 that dust accumulates unit 50, the amount that should lodge in the dust in reservoir 51 that the average amount of dust based on filter 31 trapping is predicted etc. are suitably determined the degree of depth of reservoir 51.

(2-2) cap

With reservoir 51 similarly, as shown in Fig. 5～7,9～10, cap 53 has along the length direction of the shell 11 of indoor set 100 (W direction) and the rectangular shape that extends.And, cap 53 can take as shown in Fig. 5～6 by the closed posture of the peristome of reservoir 51 52 sealings and as shown in Figure 7 peristome 52 is opened open the arbitrary posture in posture.That is, can say that cap 53 plays the effect as the lid with respect to reservoir 51, makes the dust in reservoir 51 can optionally not flow out to outside.

Particularly, the cap 53 of present embodiment forms as the parts that separate with reservoir 51.But as shown in Figure 7, cap 53 can link with reservoir 51 rotationally by hinge connect mechanism 59 described later.And cap 53 can be taked with respect to the blocked lock-out state of reservoir 51 and is disengaged the arbitrary state in the latch-release state of locking with respect to reservoir 51 by sliding locking mechanism 62 described later.In the situation that taking lock-out state, cap 53 cannot rotate with respect to reservoir 51.But in the situation that taking latch-release state, cap 53 can rotate with respect to reservoir 51.That is, cap 53 is taked lock-out state or latch-release state under the state linking through hinge connect mechanism 59 and with reservoir 51.Therefore,, if be only that user makes dust accumulate in the situation that unit 50 falls by mistake, cap 53 can not be removed from reservoir 51.

And, as shown in Figure 5, brush 55 tops that are positioned at cap 53, at cap 53, as shown in Figure 7, in the position corresponding with brush 55, be formed with dust and flow into hole 54.Particularly, dust flows into the length direction (W direction) that hole 54 is arranged to along indoor set 100 in the substantial middle of cap 53 and extends.It is for being flow into the hole in reservoir 51 for brushing 55 dust of removing from filter 31 that this dust flows into hole 54.And as hereinafter described, because brush 55 itself is by brush cleaning portions 57 cleanings (with reference to Fig. 4,5), the dust that are therefore attached to brush 55 itself also flow into and flow in reservoir 51 with hole 54 through dust.

In addition,, as shown in Fig. 6～7, at cap 53, be provided with and slide with handle 70.When cap 53 is slided, use and slide with handle 70.

(2-3) brush

As shown in Fig. 5～6, with reservoir 51 and cap 53 similarly, brush the 55 elongated shapes of length direction (W direction) that have along the shell 11 of indoor set 100, there is the shape of circular with the cross section of length direction quadrature.Brush 55 be supported in the surperficial 53c of cap 53, cap 53 take Fig. 5～6 closed posture situation lower cover portion 53 be not face 53c towards reservoir 51 sides but toward the outer side above.And, brush 55 tops that can be supported in rotatably this surface 53c, by direct contacted filter 31, from this filter 31, remove dust.Particularly, as shown in Fig. 5,7, the both ends of brushing 55 rotary middle spindle 55a are supported on respectively end 53a, the 53b of the length direction of cap 53 by axle.

Therefore,, in the situation that cap 53 rotates with respect to reservoir 51 by hinge connect mechanism 59, brush 55 and together with respect to reservoir 51, rotate with cap 53.In addition, no matter whether cap 53 is to be locked to the state of reservoir 51 and to be disengaged the arbitrary state in the state of locking, brushes 55 and itself can both above the surperficial 53c of cap 53, be rotated.

As shown in Figure 4, such brush 55 consists of core 56a and a plurality of wire rod 56b of being arranged at the side face of core 56a, and wire rod 56b has the length that can contact with filter 31.

In addition, though do not illustrate, brush 55 using brush drive motor as drive source, be rotated.Brush drive motor and for example dust accumulate unit 50 splits and are positioned at shell 11 inside of indoor set 100, and its output shaft links with the rotary middle spindle 55a of brush 55 when dust accumulates unit 50 and is installed on shell 11.Brush drive motor can consist of for example stepper motor, and is driven and control by above-mentioned indoor control part.For example, when brush 55 is rotated, the movement of filter 31 stops, and on the contrary, when filter 31 moves, indoor control part drives control to brush drive motor, and making to brush 55 becomes the state stopping the rotation.

(2-4) brush cleaning portion

With brush 55 similarly, as shown in Figure 5, brush cleaning portion 57 is installed on the surperficial 53c top of cap 53.More specifically, as shown in Figure 5, brush cleaning portion 57 configures along the length direction (W direction) of shell 11, and, outstanding towards brush 55 from the surperficial 53c of cap 53 as shown in Figure 4.And brush cleaning portion 57 tilts against the direction of rotation (that is, the direction of the arrow of the brush in Fig. 4 55) of brush 55.

Thus, in the situation that brush 55 is rotated to the direction of the arrow in Fig. 4, brush cleaning portion 57 can scrape the dust between the wire rod 56b of brush 55.

(2-5) hinge connect mechanism

Hinge connect mechanism 59 is by hinging manner, to link reservoir 51 and cap 53 so that cap 53 rotates with respect to reservoir 51 mechanism that takes to open posture as shown in Figure 7.As shown in Figure 8,9, such hinge connect mechanism 59 consists of turning cylinder 60 and bearing 61.

Turning cylinder 60 is parts of the axle when becoming cap 53 and rotating with respect to reservoir 51.Particularly, as shown in Fig. 9 (a), on the long limit 53e of the cap 53 of rectangle, alongst (W direction) is provided with three turning cylinders 60 preset distance separated from each other.As shown in Fig. 9 (b), a part of the long limit 53e of cap 53 is by otch, three turning cylinders 60 respectively with mode that this cut out portion is coupled together alongst (W direction) extend.Now, between each turning cylinder 60 and cap 53, alongst (W direction) is formed with the opening 65 of rectangle.The cross section of turning cylinder 60 is circular, suitably determines the width d1 of the length direction (W direction) of its diameter and turning cylinder 60 according to the intensity such as cap 53 and reservoir 51 etc.

In addition relation (c) with reference to Fig. 8 according to the outstanding amplitude d4(of the projected direction with bearing 61 described later) is suitably determined the width d2 of the short side direction of opening 65.That is, can say, this opening 65 is for catching the opening that under the state of the turning cylinder 60 in cap 53 sides, cap 53 can be rotated swimmingly in the bearing 61 of reservoir 51 sides when cap 53 rotates.

Bearing 61 is the parts for turning cylinder 60 being supported in the precalculated position of reservoir 51 sides.Particularly, as shown in Fig. 8 (a), on the long limit 51b of peristome 52 that forms reservoir 51, the mode that (W direction) is separated from each other preset distance with is alongst provided with three bearings 61.That is,, near 51, three bearings 61 of reservoir are formed at respectively cap 53 sides, the position of each bearing 61 is corresponding with the position of three turning cylinders 60 that is arranged at cap 53 sides respectively.And, as shown in Figure 8 (c), three bearings 61 have respectively the outstanding amount of width d4 and the shape of open C font laterally of being equivalent to laterally, to can catch toward the outer side turning cylinder 60 from the inner side of reservoir 51 on the long limit 51b of reservoir 51.The internal diameter of each bearing 61 is a bit larger tham the periphery of corresponding turning cylinder 60.

In addition, with the width d1 of the length direction (W direction) of turning cylinder 60 similarly, according to intensity such as cap 53 and reservoir 51 etc., suitably determine the width d3 of the length direction of each bearing 61, but the width d1(of length direction (W direction) that particularly the width d3 of the length direction of each bearing 61 is shorter than corresponding turning cylinder 60 is with reference to (b) of Fig. 9).

Thus, when user makes cap 53 slide to first direction D1 or second direction D2 with respect to reservoir 51 (Fig. 6), can slide on turning cylinder 60 amount of width d1 of length direction (W direction) of this axle 60 of each bearing 61.That is, can say, the difference of the width d1 of the width d3 of the length direction of each bearing 61 and the length direction of turning cylinder 60 (W direction) is the sliding distance that cap 53 can slide with respect to reservoir 51.

In addition, in Fig. 7～10 of present embodiment, exemplarily show and arrange one, add up to the situation that is provided with three hinge connect mechanisms 59 respectively arranging near the both ends of the length direction (W direction) of reservoir 51 and cap 53 near one, central authorities at length direction.But, be arranged at the quantity that dust accumulates the hinge connect mechanism 59 of unit 50 and be not limited to this.

(2-6) sliding locking mechanism

Sliding locking mechanism 62 is the mechanisms that change the state that cap 53 can take, make when cap 53 is taked closed posture, by user, cap 53 is slided (with reference to Fig. 6) to first direction D1 or second direction D2 with respect to reservoir 51, thereby cap 53 is taked lock-out state or latch-release state with respect to reservoir 51.Particularly, when cap 53 is taked closed posture, in the situation that user makes cap 53 slide to first direction D1 with respect to reservoir 51, sliding locking mechanism 62 forbids that cap 53 rotates (that is, lock-out state).On the contrary, when cap 53 is taked closed posture, in the situation that user makes cap 53 slide to the direction D2 contrary with first direction D1 with respect to reservoir 51, as shown in Figure 7, sliding locking mechanism 62 makes cap 53 can rotate (that is, latch-release state).

Therefore as shown in Figure 6, as first direction D1 and the second direction D2 of the glide direction of present embodiment, be, the direction along the length direction (W direction) of reservoir 51 and cap 53.Therefore, when user makes cap 53 slide with respect to reservoir 51, by by hand steered a reservoir 51, with another hand, make to slide and slide to first direction D1 or second direction D2 with handle 70, thereby can make simply cap 53 slide to first direction D1 or second direction D2.Like this, because first direction D1 and second direction D2 are the directions along the length direction of reservoir 51 and cap 53, therefore can guarantee fully distance that cap 53 is slided with respect to reservoir 51, and user is easy to carry out operation.

As shown in Fig. 7～8,10, such sliding locking mechanism 62 forms by accumulating side engaging portion 63 and covering side engaging portion 64.

As shown in Fig. 8 (a), on the face 51a of the inner side of reservoir 51 and near cap 53 sides, the mode that (W direction) is separated from each other preset distance with is alongst provided with three and accumulates side engaging portion 63.More specifically, the limit 51c of a side three more top parts of accumulating on the face 51a of inner side that side engaging portion 63 is positioned at reservoir 51, and be formed at that not to be provided with hinge connect mechanism 59(in long limit 51b, the 51c of edge that forms peristome 52 be more specifically bearing 61).And as shown in Fig. 9 (b), three are accumulated side engaging portion 63 and have respectively outstanding and its end portion in inside from from the face 51a of the inner side of reservoir 51 to reservoir 51 to the shape of length direction (W direction) bending.

As shown in Figure 10 (a), lid side engaging portion 64 is arranged on upper and be arranged at and to be provided with hinge connect mechanism 59(be more specifically turning cylinder 60 towards the face of reservoir 51 sides (below, be called back side 53d) in the situation that cap 53 is taked closed posture in the face of cap 53) the long limit 53f of the contrary side of the long limit 53e of a side near.With accumulate side engaging portion 63 similarly, lid side engaging portion 64 is also provided with three to be separated from each other the mode of preset distance, each position of covering side engaging portion 64 is accumulated side engaging portion 63 and is distinguished corresponding with three.And as shown in (b) of Fig. 7 and 10, three lid side engaging portions 64 have respectively from the shape that cap 53 is side-prominent to reservoir 51 and its end portion bends to length direction (W direction).

Particularly, as shown in figure 11, when cap 53 is taked closed posture, mutually the ledge 64a of corresponding lid side engaging portion 64 and the bending part 63b that accumulates ledge 63a, the bending part 64b of lid side engaging portion 64 of side engaging portion 63 and accumulate side engaging portion 63 become respectively and extend abreast the state arranging.Thus, when cap 53 slides to first direction D1, accumulate side engaging portion 63 and the 64 mutual engagings of lid side engaging portion, thereby cap 53 becomes with respect to the blocked state of reservoir 51, forbids the state rotating.On the contrary, when cap 53 slides to second direction D2, due to so far mutually engaging accumulate side engaging portion 63 and lid side engaging portion 64 is separated from each other, so cap 53 becomes the state unlocking with respect to reservoir 51, becomes and can rotate with respect to reservoir 51.
