Dust cover 4 is shape rearward prominent on the upside of rear, when installed in main body 11, is formed as on the upside of rear certainly A part for the side of line electric dust collector 1 (with reference to Figure 16 etc.).Therefore, for main body 11, equivalent in dust cover 4 The region of the underface of rear upper-side area is also formed from a part for the side of line electric dust collector 1.In present embodiment In, the small tool incorporating section 1102 as illustrated in Figure 15 etc. is set near a part for the side of the main body 11, stores conduct The cleaning of one example of small tool brush 95.Cleaning brush 95 is that such as user can be used in cleaning the work in dust cover 4 Tool, is the curved shape of peripheral shape along main body 11.Clean has bristle 951 and clamp portion 952 with brush 95.Bristle portion 951 can use when cleaning the grade of dust cover 4, and clamp portion 952 can be used when pulling down side brush 15.

By that in the curved shape of peripheral shape along main body 11, can be set along the inner circumferential of the side of main body 11 clear Sweep the required space of storage with brush 95.Such as the side according to the outside that cleaning brush 95 etc. is installed to dust cover 4 Formula, then can cause the capacity of dust cover 4 to reduce, so not preferred.In addition, made by that will clean with the storage space of 95 grades of brush For the loading and unloading area of dust cover 4, can suppress to clean situation about surprisingly being come off with 95 grades of brush.

In addition, instead of present embodiment, such as cleaning brush 95 or additional can also be replaced, storage is used to pull down side brush 15 fixture and other small tools.

The storage mode of small tool be not limited to it is above-mentioned, if the state that dust cover 4 is installed to main body 11 will be by main body 11 and the region that surrounds of dust cover 4 set to main body 11.

(adverse current check valve 44)

Adverse current check valve 44 has the interarea 441 for the opening that can block the other end as conduit 42, one or only The vertical protuberance 442 for being installed to interarea 441 and the outside of conduit 42 being projected upwardly into the side almost parallel with interarea 441, with And the force section 443 to the direction force for making interarea 441 and the rotation of protuberance 442.In the present embodiment, protuberance 442 It is separately positioned on the outside in the direction almost parallel with interarea 441.

Force section 443 is to block the component that the direction of opening exerts a force adverse current check valve 44 to interarea 441, can be used each Component known to kind, such as spring can be used.Force section 443 is, for example, helical spring, itself can become rotation axis.

Therefore, in the state of the effect of no external force, adverse current check valve 44 blocks the other end of conduit 42.

When dust cover 4 is installed to main body 11, protuberance 442 and the work for being arranged on the region for storing dust cover 4 To resist poor 119 contact of the guide step of force section.If guide step poor 119 is provided in main body 11 and pulls down dust cover 4 just can be visual region two step difference parts.Guide step poor 119 is set each along the installation direction of dust cover 4 Put, extend in the present embodiment from upper rear direction inferoanterior.

Due to being installed to main body 11 and dust cover 4 moves downwards with dust cover 4, protuberance 442 and guiding rank Ladder poor 119 is contacted and slided, direction stress of the interarea 441 in release opening respectively.Thus, the resistance of adverse current check valve 44 force The active force in portion 443, the other end of release catheter 42.Guide step poor 119 as illustrated in present embodiment is applied by resistance Power portion and the contact of protuberance 442, interarea 441 can be discharged by the power reverse with the active force of force section 443 as leading The opening of the other end of pipe 42.

Specifically, the other end that the rotation using the long side direction of adverse current check valve 44 as axis carrys out release catheter 42 is produced. Because the adverse current check valve 44 of present embodiment is generally rectangular, if using the short side direction of adverse current check valve 44 as The rotation of axis, the rotation using the direction vertical with interarea 441 as axis, then it is larger in order to make to carry out to rotate required space, preferably Make to rotate by axis of long side direction.That is, force section 443 rotates adverse current check valve 44 by axis of the long side direction of interarea 441.

In addition, protuberance 442 is inverse to make by any component (resistance force section) for contacting self-propelled electric dust collector 1 Stream check valve 44 is in open mode.

Set on the front in poorer than the guide step of present embodiment 119 front end and have the gap 1101, pacified in dust cover 4 It is attached in the state of main body 11, adverse current check valve 44 is directed step difference 119 and presses and slide, and is received to gap 1101.Seam Gap 1101 is located at the outside on the principal direction perspective plane of frame 121.Therefore, be mounted with the state of dust cover 4, conduit 42 it is another Dust sensor unit 12 is held and touched, particularly clings in the present embodiment and is close to component 124.

[structure set from suction port 1131 to main savings room 41]

Particularly as Figure 14 is illustrated, for principal direction, the other end of the size 92 of dust sensor unit 12 than conduit 42 The size 93 of side is short.That is, a part for the distance of main savings room 41, portion preferably bigger than size 92 are connected to from suction port 1131 Divide and formed by the size 93 of the another side of conduit 42.Thereby, it is possible to be set from suction port 1131 to the region of main savings room 41 A part for dust cover 4 is put, the volume of dust cover 4 can be expanded.

Here, conduit 42 possesses erection part 421, the erection part 421 formed conduit 42 one end, have size 94 and on Lower extension.Erection part 421 can suppress the another side that dust drains to conduit 42 from main savings room 41.

Here, as size 93, it may be considered that virtually (make main savings room 41 near for plane the lower surface of dust cover 4 It is similar to box), with line measurement, from the plane to the dust sensing almost parallel with the size 92 of dust sensor unit 12 The distance of device unit 12.In addition, the main savings room 41 of present embodiment can be contemplated into box.

[closing of the conduit 42 carried out by adverse current check valve 44]

As described above, in the state of dust cover 4 is installed to main body 11, adverse current check valve 44 is stored in rotating brush 14 Upside.If dust cover 4 pulled down from main body 11, adverse current check valve 44 is rotated by the active force of force section 443, Block the opening of the 42 side other end of conduit.Thus, even if having put aside dust in conduit 42, dust can also be suppressed from dust cover 4 overflow.In addition, interarea 441 can be tabular or can suppress mesh of the dust by degree.

[the filling up detection of dust]

If self-propelled electric dust collector 1 attracts dust, the dust of attraction puts aside main savings room 41 first, if main product Storage room 41, which is filled up then also to put aside, arrives conduit 42.Because conduit 42 is tilted towards towards compared to gravity direction towards horizontal direction side Under, institute falls so as to suppressing dust from conduit 42.Further, since compared to horizontal direction towards gravity direction side, so main product Rear dust is filled up in storage room 41, and easily savings arrives conduit 42 quickly, easily detects dust by dust sensor unit 12.

In addition, although it is to have state more than needed but on conduit 42 in main savings room 41 that can be suppressed by erection part 421 Wander dust.What the dust cover 4 of present embodiment was included due to being provided with main savings room 41 on front side of one end of conduit 42 More than half ratios in space, so easily savings arrives front side to dust.But due to more than half ratios in space and conduit 42 Between be provided with erection part 421, therefore even if acceleration with from self-propelled electric dust collector 1 to the front as main moving direction And dust is moved to rear, it also can effectively suppress dust and fall on conduit 42.That is, from front towards rear, wrapped with main savings room 41 More than half ratios in the space contained, erection part 421, the order of one end of conduit 42 are set.

If also putting aside dust in conduit 42 and substantially filling up, dust persistently blocks the light of illuminating part 122, continues light accepting part The state that 123 light income reduces.Filling up for dust cover 4 is detected by detecting the state, is capable of informing a user that or starts Self-propelled electric dust collector 1 is returned to the control of battery charger cradle (not shown).

[detection of the dust amount passed through]

If the light moment of illuminating part 122 is blocked, the light income pulse type of light accepting part 123 is reduced.Thereby, it is possible to detect Dust passes through towards dust cover 4.In the present embodiment, suction port is compared for the sectional area of principal direction, 14 side of rotating brush 1131 is big, small in frame 121 or conduit 42, big in main savings room 41.That is, from the storage space of rotating brush 14 to main savings room 41 The sectional area of distance is minimum in frame 121 and/or conduit 42.Therefore, the shape of the dust of suction and conduit 42 is accordingly Focus on the small frame 121 of sectional area.Because illuminating part 122 and light accepting part 123 are arranged on frame 121, the majority of dust leads to Cross between illuminating part 122 and light accepting part 123.That is, being capable of high-precision measuring dust amount.

In addition, because the conduit 42 that the dust after having passed through frame 121 is substantially the same by sectional area, near frame 121 It is difficult to produce vortex.That is, suppress dust countercurrently causes to repeat to detect due to vortex.Also, because pass through cuing open after conduit 42 Area expands, and institute is so as to suppress windage loss.

In addition, sectional area than 12 more upstream side of dust sensor unit, i.e., from suction inlet portion 113 to dust sensor list The sectional area of member 12 can be with monotone decreasing.In such manner, it is possible to suppress to produce vortex in 12 upstream of dust sensor unit, dust repeats Detected by dust sensor unit 12.

[layout]

Figure 17 is the stereogram for the self-propelled electric dust collector 1 for pulling down upper casing 111, and Figure 18 is the E-E sectional views of Fig. 1.

In order to make the small size up and down of self-propelled electric dust collector 1, size up and down and the electric fan 16 of main body 11 Upper and lower size is roughly the same.Such as Figure 17 illustrations, it is configured to if pulling down the state of upper casing 111, then it can be seen that covering electricity The convex form 162 of a part for the upper surface of dynamic fan 16.Thus, the miniaturization of the size up and down of main body 11 is contributed to.In addition, The bottom surface side of main body 11 can also have convex form prominent downwards seeing the position overlapping with electric fan 16 from down.

In the lower side space of upper casing 111, by setting convex form 162, only protrude the part of 16 upper end side of electric fan While to the space, correspondingly become the space that can configure other parts with the protrusion size quantity.That is, in convex form Height region where 162 is configured with other parts.

Such as be configured with the present embodiment switchboard 22 a part, circuit substrate or circuit element, 7 sections and The light-emitting component of LED etc., becoming can use upper casing 111 to cover these composition.Thus, easily reduce easily by electric fan 162 Size influence self-propelled electric dust collector 1 size up and down.In addition it is also possible to configure a part for switchboard 22, circuit Other arbitrary parts outside the light-emitting component of substrate or circuit element, 7 sections and LED etc., can also only configure these A part.Below the height dimension of the preferred convex form 162 of height dimension of the part of these configurations, for example, can be 5mm with Under, below 3mm, below 2mm or below 1mm.

In addition, electric fan 162 is installed as blowing in the horizontal direction, i.e. blade openings into general horizontal direction (such as from Below horizontal direction ± 10 degree, preferably less than ± 5 degree).In this way, as in the present embodiment, the path formed in the horizontal direction Upper easily connection electric fan 162 and dust cover 4.That is, the necessity for extending path in the height direction, energy can be reduced Enough suppress height dimension.

In addition it is also possible to by pull down upper casing 111 expose electric fan 16 upper end side part or configuration on The part of the upper end side of the flat component covering electric fan 16 for the other parts stated.

If in addition, being usually arranged obliquely the electric fan 16 of cylindrical shape, the size up and down of increase main body 11 is produced Necessity, so the axial direction of electric fan 16 deviates less than ± 10 degree, preferably ± 5 degree horizontally or from horizontal direction Below.

In the case where the axis of electric fan 16 looks up, such as Figure 18 illustrations, the rotation axis side of arm 1141 is located at and cylinder The inner side in the external generally square region of the electric fan 16 of type.The region easily becomes dead zone, but in this way A part for configuration arm 1141 efficiently uses space to realize the miniaturization of self-propelled electric dust collector 1.In addition, because make exhaust Mouth 1126 can shorten row positioned at the underface of electric fan 16 or the underface of the opening in the downstream of electric fan 16 Gas wind path.

Present embodiment possesses the various structures for miniaturization, and as a result, it is possible to make to be closely sized to electric fan up and down 16 size up and down.Specifically, even if considering by influence of the driving wheel 116 to size, the upper of electric fan 16 can also be made Lower size is accommodated in the ruler up and down for the self-propelled electric dust collector 1 being placed on self-propelled electric dust collector 1 in the state of ground More than the 70% of very little (that is, the size up and down for the state that arm 1141 rotates to upside and stores driving wheel 116), preferably more than 75% Or more than 85% scope.

The size up and down in the region of upper casing 111 and the encirclement upper and lower sides of lower casing 112 and the size up and down of electric fan 16 are big Cause identical.Specifically, the size up and down in the region that the size up and down of electric fan 16 is surrounded for upper casing 111 and lower casing 112 More than 90%, preferably more than 95%.

In addition, as described above, in the structure loaded on the main body 11, the big component of weight is rechargeable battery 19, electronic Fan 16.If rechargeable battery 19 is configured to center side, wiring etc. is easily hindered, so in the present embodiment will be electronic Fan 16 is configured at center side, and rechargeable battery 19 is configured at front side.

[rotary speed of side brush 15]

Self-propelled electric dust collector 1 possesses side brush 15 respectively in left side and right side.In the present embodiment, becoming can The composition of the rotary speed of side brush 15 is changed respectively.Specifically, the side for having wall with left side is performed in self-propelled electric dust collector 1 In the case of the wall side cleaning modes of formula traveling, the rotary speed of the side brush 15 in the left side of the same side with side where wall is controlled Rotary speed for the side brush 15 than the opposing party is fast.Thus, it is more effectively carried out the cleaning on wall side.Wall side cleaning modes can lead to Cross various known methods to perform, for example, persistently detecting metope by the distance measuring sensor 210 set in the left side of main body 11 The mode of (barrier) carries out traveling control to realize.

In addition, it can also be controlled in the same manner in the case of performing the wall side cleaning modes travelled in a manner of there is wall on right side. In addition, it is than other control models, example by the rotary speed control of the side brush 15 of the executory wall side of wall side cleaning modes Reroute is the reflection for restarting traveling behind the direction that metope or barrier leave if detecting metope or barrier The executory rotary speed height of driving mode can also obtain identical effect.In addition, it is identical with wall side, intersect in 2 metopes Corner can also control rotary speed or following torques in the same manner.

[torque of side brush 15]

Side brush 15 is driven by the side brush motor 152 of the driven by power by rechargeable battery 19 respectively.In the present embodiment, DC motors are used as side brush motor 152.For DC motors, even if the voltage of average time output is identical value, also can A side of duty cycle high (voltage application time length) is set to transmit high torque.Side brush 15 if contacted with wall or barrier, then by Reduced in its friction torque, so being easily reduced sweeping efficiency.

Therefore, in the present embodiment, for example, performing the feelings of the wall side cleaning modes travelled in a manner of there is wall in left side Under condition, the duty cycle control of the side brush motor 152 of torque can will be transmitted to the side brush 15 in the left side of the side identical with there is wall side It is made as the duty cycle higher than transmitting torque side brush motor 152 to the side brush 15 of the opposing party.

In addition, because rechargeable battery 19 energy reduce and output voltage reduce in the case of, even identical duty Specific torque can also reduce, so making the dump power more low duty ratio of rechargeable battery 19 bigger.

In addition, with it is identical the reasons why, need the torque that exports also different according to the material on ground, so can also base area The species in face determines duty cycle.For example, it can control as the duty cycle height in the Carpet-cleaning compared with floor sweeping.

Further, it is possible to make dust sensor unit 12 dust detect number it is bigger, duty cycle is lower.Thus, dust amount It can prevent dust from scattering by side brush 15 in big region.

In addition, it is to control mould than others by the Duty ratio control of the side brush 15 of the executory wall side of wall side cleaning modes Formula, for example detect that then Reroute is to restart traveling behind the direction that metope or barrier leave for metope or barrier The executory rotary speed height of reflection driving mode can also obtain identical effect.

[sensor class]

Figure 23 is the outline for the control device 2 and equipment being connected with control device 2 for representing self-propelled electric dust collector Structure chart.Buffer sensor (detection of obstacles unit) is that the retrogressing of detection buffer 18 (in other words, connects with barrier Touch) sensor.

The distance measuring sensor 210 (detection of obstacles unit) of the illustrations such as Fig. 2 is the infrared ray for the distance for detecting barrier Sensor.In the present embodiment, amount to distance measuring sensor is provided with 5 at front 3 and at side 2.

Distance measuring sensor 210 has the illuminating part (not shown) for making infrared light emission and receives infrared ray to be reflected by barrier And the light accepting part (not shown) of the reflected light returned.Based on the reflected light detected by the light accepting part, barrier is calculated Distance.In addition, formed in buffer 18 at least near distance measuring sensor by the resin or glass that can make infrared ray transmission.

The ground of the illustrations such as Fig. 3 with distance measuring sensor 211 (ground detection unit) be measure ground distance it is infrared Line sensor, is arranged on all around at 4 of lower surface of lower casing 112.More specifically, positioned at the front side of auxiliary wheel 17, rotation Turn on the outside of the rear side of brush 14 and scraping brush 13, the front side of each driving wheel 116 and left and right directions.

By detecting the big step difference of step etc. with distance measuring sensor by ground, self-propelled electric dust collector can be prevented 1 falls (from step etc.).For example, detecting that there is the step difference of 30mm or so in front with distance measuring sensor by ground In the case of, control device 2 controls driving motors to retreat main body 11, changes direct of travel.

In addition, the ground distance measuring sensor 211 in the front side of auxiliary wheel 17 (front of lower casing 112) detects from the ground Distance it is remote, and the ground distance measuring sensor 211 of the rear side of rotating brush 14 (rear end side of lower casing 112) detects from the ground In the case that distance is near, control device 2 can also make main body 11 keep intact to move on.This is because consider such detection Combination when, be mostly that self-propelled electric dust collector 1 is stepping on the situation of step difference.In the same manner, on the ground of the front side of auxiliary wheel 17 Detect that distance from the ground is near with distance measuring sensor 211, and the ground distance measuring sensor 211 of the rear side of rotating brush 14 detects To distance from the ground it is remote in the case of, control device 2 can also make main body 11 keep intact to move on.Here it is so-called It is, for example, less than ground distance measuring sensor 211 in the case that self-propelled electric dust collector C is travelled on flat ground that " near ", which is, The distance of detection, " remote " are that ground is surveyed in the case of being greater than self-propelled electric dust collector C travelings on flat ground The distance detected away from sensor 211.In addition it is also possible to set one or two appropriate threshold values, knot in comparison Fruit.

Exported using the driving motors pulse shown in Figure 23, detect rotary speed, the rotation angle of driving motors 1161.This Outside, control device 2 based on by driving motors pulse output detection rotary speed, rotation angle and reducing gear gearratio and The diameter of driving wheel 116, calculates translational speed, the displacement distance of main body 11.

Driving motors electric current tester is the meter measured to the electric current flowed in the armature winding of driving motors 1161 Survey device.In the same manner, electric fan surveys device with galvanometer and the current value of electric fan 16 is measured, rotating brush motor electric current Tester measures the current value of rotating brush motor 1133.Two side brush motors survey device to side brush motor 152 with galvanometer Current value measured.The current value of measurement is output to control device 2 by each electric current tester.Utilize the detection of current value Twine to rotating brush as a result, can for example detect foreign matter and rotate the exception of stopping, can be by operation button come to user report.

In addition, according to the current value of rotating brush motor 1133 and the current value of driving motors 1161, detection main body 11 travels Ground state, such as be identified as then making on carpet the input increase of electric fan 16 to increase attraction, on ground The input of electric fan 16 is then set on plate smaller and suppresses the control of the consumption electric power of rechargeable battery 19.

If detecting dust by dust sensor unit 12, make the input of electric fan 16 increase Time constant. The input of the electric fan 16 increase time (such as extension) will not be determined according to the dust amount of detection.Thus, electronic wind is suppressed The consumption electric power of fan 16.In addition, even if detecting dust also without the reversion of main body 11, reciprocating action.Thereby, it is possible to avoid The reduction of translational speed.
