Application point portion 433 is further rearward (to surpass in the state of user is located at upside in handle 43 to angle of rotation is made Cross 90 ° of direction) when assigning power, the part that is contacted with the upper surface side of main body 11.Under the state, application point portion 433, which becomes, to be made The application point for the power that dust-collecting box 4 rises from main body 11, rotation axis become fulcrum.During thereby, it is possible to dismantle dust-collecting box 4 as user Auxiliary.As the upper surface side of main body 11, and it is not particularly limited, such as guiding step 119 described later can be arranged to.

[shape of dust-collecting box 4 and small tool incorporating section]

Dust-collecting box 4 is in shape rearward prominent on the upside of rear, is formed to walk certainly when being installed in main body 11, on the upside of rear A part for the side of formula electric dust collector 1 (with reference to Figure 16 etc.).Therefore, on the upside of the rear being located in dust-collecting box 4 of main body 11 The region of the underface in region is also formed from away a part for the side of formula electric dust collector 1.In present embodiment, in the main body The exemplary small tool receiving portions 1102 such as Figure 15 are equipped near a part for 11 side, are accommodated with an example as small tool Cleaning with brush 95.Cleaning brush 95 for example can be used in user and clean in dust-collecting box 4, and in curved along the peripheral shape of main body 11 Bent shape.Clean has bristle 951 and clamp portion 952 with brush 95.Bristle portion 951 can be used when cleaning the grade of dust-collecting box 4, Clamp portion 952 can be used when dismantling side brush 15.

By making the curved shape of peripheral shape along main body 11, so as to be set along the inner circumferential of the side of main body 11 Clean the space needed for the storage of brush 95.For example, when the shape for making the outer surface that cleaning brush 95 etc. is assemblied in dust-collecting box 4 During state, because the reduction of the capacity of dust-collecting box 4 can be caused, it is not recommended that.In addition, make the storage space shape of cleaning 95 grades of brush Into the loading and unloading area of dust-collecting box 4, the state of affairs such as surprisingly come off so as to suppress to clean with brushing 95 grades.

In addition it is also possible to substitute present embodiment, so that for example substitution is cleaned with brush 95 or added, storage is used to tear open Unload the fixture of side brush 15, other small tools.

The storage form of small tool is not limited to the above situation, as long as in the state of dust-collecting box 4 is installed on main body 11, The region surrounded by main body 11 and dust-collecting box 4 is arranged on main body 11.

(non-return valve 44)

Non-return valve 44 has：The interarea 441 of the opening of the other end as pipeline 42 can be blocked；Pacify to one or split Loaded on interarea 441, and project upward in the side almost parallel with interarea 441 protuberance 442 than pipeline 42 in the outer part；And The force section 443 to exert a force to the direction for rotating interarea 441 and protuberance 442.In the present embodiment, protuberance 442 with The outside in the almost parallel direction of interarea 441 is set respectively.

Force section 443 is to the component for making the direction of 441 occlusion of openings of interarea exert a force non-return valve 44, can be used various Known component, such as spring can be used.If force section 44 is made such as disc spring, its own can become rotation axis.

Therefore, in the state of external force is not done manual work, non-return valve 44 blocks the other end of pipeline 42.

When dust-collecting box 4 is assemblied in main body 11, the conduct in region of the protuberance 442 with being arranged on storage dust-collecting box 4 is counter to be applied The guiding step 119 in power portion contacts.Guiding step 119 be provided in main body 11 when dismantling dust-collecting box 4 it can be seen that region Two step parts.Step 119 is guided to be set respectively along the installation direction of dust-collecting box 4, in the present embodiment, from behind and above Extend towards front lower place.

By with the movement downwards of dust-collecting box 4 that dust-collecting box 4 is assembled to main body 11, protuberance 442 respectively with guiding Step 119 is contacted and slided, and stress on the direction of opening is opened making interarea 441.Thus, non-return valve 44 resists force section 443 Active force, the other end of pipeline 42 is opened.As exemplary guiding step 119 in present embodiment, exerted a force by counter Portion and the contact of protuberance 442, interarea 441 bear the power being oppositely directed to the active force of force section 443, make so as to open For the opening of the other end of pipeline 42.

Specifically, the rotation using the long side direction of non-return valve 44 as axis is produced, the other end of pipeline 42 opens.This implementation The non-return valve 44 of mode is substantially rectangular shape, therefore, for using the short side direction of non-return valve 44 as axis rotation, with interarea 441 vertical directions are rotation of axis etc., it is necessary to are expanded to be rotated and required space, thus it is preferred to long side side Rotated to for axis.That is, force section 443 rotates non-return valve 44 by axis of the long side direction of interarea 441.

In addition, as long as protuberance 442 can be by contacting the arbitrary component (anti-force section) of Self walking electric dust catcher 1 Non-return valve 44 is set to become open mode.

Gap 1101 is equipped with the front of the front end of the guiding step 119 of present embodiment, master is installed in dust-collecting box 4 In the state of body 11, non-return valve 44 is directed the pressing of step 119 while sliding, so as to be accommodated in gap 1101.Gap 1101 positioned at the outside on the principal direction perspective plane of frame 121.Therefore, in the state of dust-collecting box 4 is equipped with, the other end of pipeline 42 Dust sensor unit 12 is contacted, especially, in the present embodiment, is close to being close to component 124.

[being arranged on from suction port 1131 to the structure of main reservoir 41]

Example particularly as shown in figure 14, in a main direction, the size 92 of dust sensor unit 12 is more another than pipeline 42 The size 93 of one end is short.That is, the size 93 of the another side of pipeline 42 is formed as than connecting from suction port 1131 to main accumulation A part of preferred size 92 of the distance of room 41 is big.Thereby, it is possible to be set from suction port 1131 to the region of main reservoir 41 A part for dust-collecting box 4, therefore the volume of dust-collecting box 4 can be expanded.

Here, pipeline 42 can possess erection part 421, erection part 421 forms the one end of pipeline 42, has size 94 simultaneously Extension up and down.Erection part 421 suppresses another side leakage of the dust from main reservoir 41 to pipeline 42.

Here, as size 93, it can be seen that being following distance, i.e.,：The lower surface of dust-collecting box 4 is assumed plane (will Main reservoir 41 is similar to box), measured according to the straight line almost parallel with the size 92 of dust sensor unit 12 From the plane to the distance of dust sensor unit 12.In addition, the main reservoir 41 of present embodiment is it can be considered that be box.

[blocking of the non-return valve 44 to pipeline 42]

As described above, in the state of dust-collecting box 4 is assemblied in main body 11, non-return valve 44 is accommodated in the upper of rotating brush 14 Side.When dust-collecting box 4 is dismantled from main body 11, non-return valve 44 is rotated because of the active force of force section 443, and it is another to block 42 side of pipeline The opening of one end.Thus, dust is contained in pipeline 42, can also suppress dust and be scattered from dust-collecting box 4.It is in addition, main Face 441 can also be tabular or can suppress the mesh-shape for the degree that dust passes through.

[the filling detection of dust]

When Self walking electric dust catcher 1 attracts dust, the dust being attracted lodges in main reservoir 41 first, when main product When depositing room 41 and filling, pipeline 42 is also lodged in.Pipeline 42 is directed towards the direction obliquely downward that proportion force direction leans on horizontal direction side, therefore It can suppress dust to fall from pipeline 42.In addition, direction leans on gravity direction side than horizontal direction, therefore filled in main reservoir 41 Afterwards, easily accumulate dust in pipeline 42 faster, dust is detected easily by dust sensor unit 12.

In addition, using erection part 421, whether or not in main reservoir 41 there is rich state can suppress dust Circulate and fall in pipeline 42.The dust-collecting box 4 of present embodiment is equipped with inside main reservoir 41 in the front side of one end of pipeline 42 Including space more than half ratios, therefore dust easily lodges in front side.But because space more than half ratios with It is equipped with erection part 421 between pipeline 42, therefore even if as Self walking electric dust catcher 1 is to the front as main moving direction Accelerate, dust rearward moves, also can effectively suppress dust and be fallen to pipeline 42.That is, from front towards rear, main reservoir More than half ratios in the space that 41 inside include, erection part 421, one end of pipeline 42 are sequentially arranged position.

When dust, which lodges in pipeline 42, also substantially to be filled, dust persistently covers the light of illuminating part 122, keeps light accepting part The state that 123 light income reduces.By detecting the state, dust-collecting box 4 can be detected and filled, notify user, or start to make certainly Walk the control that formula electric dust collector 1 returns to cradle (not shown).

[detection of the dust amount passed through]

When the light moment of illuminating part 122 is shielded, reduce the light income pulse feature of light accepting part 123.Thereby, it is possible to visit Dust measuring angstrom passes through to dust-collecting box 4.In the present embodiment, for the sectional area in principal direction, since suction port 1131, rotation Brush 14 sides to become larger, diminish in frame 121, pipeline 42, become larger in main reservoir 41.That is, from the storage space of rotating brush 14 to main product The sectional area for depositing the distance of room 41 is minimum in frame 121 and/or pipeline 42.Therefore, the dust of suction exists according to the shape of pipeline 42 The small frame 121 of sectional area is concentrated.Illuminating part 122 and light accepting part 123 are arranged on frame 121, therefore most of dust passes through illuminating part 122 And between light accepting part 123.That is, being capable of accurately measure dust amount.

In addition, by the dust after frame 121 by the roughly the same pipeline 42 of sectional area, therefore, it is difficult near frame 121 Produce vortex.That is, it is because of vortex and countercurrently multiple so as to be detected to suppress dust.Moreover, pass through the sectional area after pipeline 42 Expand, therefore windage loss can be suppressed.

In addition, the sectional area of the upstream side of dust sensor unit 12, i.e. from suction inlet portion 113 to dust sensor unit 12 Sectional area can also monotone decreasing.In such manner, it is possible to suppress 12 upstream of dust sensor unit produce vortex and dust by dirt Angstrom sensor unit 12 detects repeatedly.

In the axial visual angle of electric blower 16, such as Figure 18 examples, the rotation shaft side of stent 1141 is located at and cartridge type The inner side in the external generally square region of electric blower 16.The region easily becomes dead band, but configures in this way A part for stent 1141, effectively can flexibly use space, realize the miniaturization of Self walking electric dust catcher 1.In addition, by In make exhaust outlet 1126 be located at the underface of electric blower 16, electric blower 16 downstream opening underface, because This can shorten exhaust wind path.

Present embodiment possesses the various structures for miniaturization, as a result, can make to be closely sized to electronic drum up and down The size up and down of wind turbine 16.Specifically, it is configured to, even if considering influence of the driving wheel 116 to size, also makes electric blower 16 size up and down falls into the Self walking electric dust catcher 1 that is placed in Self walking electric dust catcher 1 in the state of floor Upper and lower size (that is, stent 1141 rotates to upside and stores the size up and down in the state of driving wheel 116) more than 70%, it is excellent Select more than 75% or more than 85% scope.

Upper shell 111 and lower housing shell 112 the region that upper and lower sides surround size up and down and electric blower 16 up and down Size is roughly the same.Specifically, the region that the size up and down of electric blower 16 is surrounded for upper shell 111 and lower housing shell 112 Size up and down more than 90%, be preferably more than 95%.

In addition, as described above, it is rechargeable battery 19, electronic air blast to be placed in the component that weight is big in the structure of main body 11 Machine 16.If rechargeable battery 19 is configured at center side, distribution etc. is easily hindered, therefore in the present embodiment by electronic air blast Machine 16 is configured at center side, and rechargeable battery 19 is configured at front side.

[rotating speed of side brush 15]

Self walking electric dust catcher 1 has side brush 15 respectively in left side and right side.In the present embodiment, making can be right The structure of the rotating speed difference make a change of side brush 15.Specifically, Self walking electric dust catcher 1 is located at left side in execution with wall In the case of the wall angle cleaning modes that mode travels, it is the side brush for making the i.e. left side in the side identical with the side residing for wall to control The rotating speed of the side brush 15 of 15 rotating ratio the opposing party is fast.Thereby, it is possible to be more effectively carried out the cleaning at wall angle.Wall angle cleaning modes It can be performed by various known methods, for example, can be by with lasting arranged on the distance measuring sensor 210 in the left side of main body 11 The mode of detection wall (barrier) carries out traveling control to realize.

In addition, in the case where performing the wall angle cleaning modes travelled in a manner of arm is located at right side, also can be similarly It is controlled.In addition, even if control is the other controls of rotating ratio of the side brush 15 for the executory wall side for making wall angle cleaning modes Pattern, for example detect wall, travel again again to the direction change advance route away from the wall, barrier after barrier it is anti- It is high to penetrate the executory rotating speed of driving mode, can also obtain same effect.In addition, in the same manner as wall angle, even in two walls The turning that face is intersected, also can similarly control rotating speed, moment of torsion described later.

[moment of torsion of side brush 15]

While brush 15 respectively by driven by power by rechargeable battery 19 while brush motor 152 drive.In present embodiment, make For side brush motor 152, DC motors are employed.Even if the voltage that DC motor average times export is identical value, duty cycle higher (electricity Pressure application time is longer) a side can transmit the moment of torsion of higher.When 15 contact walls, barrier are brushed in side, due to the friction, turn round Square is reduced, therefore sweeping efficiency is easily reduced.

Therefore, the wall angle cleaning modes in the present embodiment, such as in execution travelled in a manner of making wall be located at left side In the case of, it can control to make the while brush horse that moment of torsion is transmitted in brush 15 in the left side of the identical side in the side residing for Xiang Yubi Duty cycle up to 152 is higher than the duty cycle to the opposing party's brush motor 152 when brush 15 transmits moments of torsion.

In addition, the energy in rechargeable battery 19 is reduced in the case of output voltage reduction, under identical duty cycle, turn round Square reduces, therefore the remaining capacity of rechargeable battery 19 is lower, more increases duty cycle.

In addition, under the reasons why same, it is different according to the material of floor, it should which that the moment of torsion of output is also different, therefore can To determine duty cycle according to the species of floor.For example, it is, compared to cleaning in wood floors, to make in cleaning carpet that can control Duty cycle become higher.

Moreover, the dust detection number of dust sensor unit 12 is more, then it more can reduce duty cycle.Thus, exist The region of a large amount of dust, can avoid dust from being dissipated by side brush 15 and spread.

In addition, even if the duty cycle for the side brush 15 for being the executory wall side for making wall angle cleaning modes is controlled than other controls Pattern, for example detect wall, travel again again to the direction change advance route away from the wall, barrier after barrier it is anti- It is high to penetrate the executory duty cycle of driving mode, can also obtain same effect.
