The dust storage part comprises first dust storage part 214 that is stored in the dust of separating in the first cyclone unit 230 and the second dust storage part 216 that is stored in the dust of separating in the second cyclone unit 300.

Here, dust-collector main body 210 comprise the first wall 211 that forms the first dust storage part 214 with first wall 211 second walls 212 relevant, that form the second dust storage part 216.That is to say that second wall 212 covers the predetermined portions in the outside of first wall 211.

Therefore, form the second dust storage part 216 in the outside of the first dust storage part 214.

Because the second dust storage part 216 is arranged in the outside of the first dust storage part 214, make the size maximization of the dust storage part 214 of winning, institute is so that the dust of the first dust storage part 214 collection maximum capacity.

In a circumferential direction, formed the bend 219 that is arranged in lower end in the first wall 211, the support first cyclone unit 230 at first wall 211 places.Therefore, the top of the first dust storage part 214 has than at the bigger diameter of diameter as the bottom at outstanding 219 places, the end of standard.

The top of dust-collector main body 210 is opened, so that allow the user empty dust with 210 reversings of dust-collector main body the time, and cover 250 is connected with the top of dust-collector main body 210.

In addition, the first cyclone unit 230 is connected the downside place of cover 250, so that can separate with cover 250 when emptying the dust that is stored in the dust memory main body 210.

Here, present embodiment is constructed to: the first cyclone unit 230 is connected with cover 250, but can allow the first cyclone unit 230 and cover 250 form single structure.

In the first cyclone unit 230, provide dust path of navigation 232, this dust path of navigation 232 will easily be discharged into from the dust that air separation is come out the first dust storage part 214,

Here, dust path of navigation 232 guides the dust of separating to fall after flowing through tangential direction.

Therefore, formed the import of dust path of navigation 232 at the place, side of the first cyclone unit 230, and formed outlet 234 at the place, bottom of the first cyclone unit 230.

As mentioned above, cover 250 is connected with dust-collector main body 210.That is to say that cover 250 opens and closes the first dust storage part 214 and the second dust storage part 216 simultaneously.

Therefore, the cover 250 that will be connected with the first cyclone unit 230 as the user separates with dust-collector main body 210, will be stored in dust emissions in the first dust storage part 214 and the second dust storage part 216 when outside, the top of dust-collector main body 210 is opened fully.In addition, when the user reversed dust memory cell 210, dust was easily emptied.

At this moment because the user at dustbin outside or above with cover 250 separately from dust-collector main body 210, to empty dust-collector main body 210, so prevented the pollution once more of the inside after the cleaning.

In addition, be emitted on the bottom that penetrates cover 250 in the first cyclone unit 230 with the steam vent 251 of dust separating air.In addition, steam vent 251 is connected with the top of the filter component 260 of a plurality of holes 262 with the preliminary dimension that is positioned on the external peripheral surface.

Therefore, the air by first dust separation in the first cyclone unit 230 is handled by after the filter component 260, is discharged in the steam vent 251.

In addition, in cover 250, form path 253, flowing to first air outlet slit 252 from the guiding of the air the first cyclone unit 230 that steam vent 251 emits.That is to say that this path 253 is the paths that connect the steam vent 251 and first air outlet slit 252.

Simultaneously, a pair of compression member 270 and 280 is disposed in the dust-collector main body 210, to reduce to be stored in the volume of the dust in the first dust storage part 214, increases dust and collects capacity.

Here, this to compression member 270 and 280 owing to interaction has each other reduced the volume of dust, and the maximum dust that has increased dust-collector main body 210 is thus collected capacity, increases the density that is stored in the dust in the dust-collector main body 210 simultaneously.

Hereinafter for convenience, this is called as first compression member 270 to one in compression member 270 and 280, and another is called as second compression member 280.

In addition, 170 places have formed setup unit 176 at the dust-collector installation portion, with the setting of guiding guiding rib 290, and at the setting slot 295 of guiding rib 290 places formation corresponding to setup unit 176.

Utilize setup unit 290 and setting slot 295, easily dust-collector 200 is installed in dust-collector installation portion 170 places, and prevent the shake of dust-collector 200 when being installed in the state at dust-collector installation portion 170 places.

Place, bottom at dust-collector installation portion 170 provides described after a while microswitch, with the position of rotation of perception driven gear 410.In addition, bar 440 is exposed to dust-collector installation portion 170, starts and closes microswitch 430 so that make when touching driven gear 410.

For this reason, form through hole 177 at dust-collector installation portion 170 places, to expose the part of rod 440.In addition, form internal-rib 178 and external fin 179 at dust-collector installation portion 170 places, with the bar 440 of protecting part to come out.

Now will detailed operative relationship with reference to driven gear and microswitch.

Fig. 9 is the perspective view according to the bottom of driven gear of the present invention.

With reference to figure 9 to 10, microswitch 430 is disposed in the bottom place of driven gear 410, thereby allows the bar 440 that the allows microswitch 430 opening and closing downside in the face of driven gear 410.

Driven gear 410 comprises circular tabular main unit 412, extend, touch the contact rib 413 of bar 440 and a plurality of gear teeth 416 that form along the circumference of the lateral face of main unit 412 downwards from the bottom of main unit 412.

Specifically, 413 places have formed affirmation groove 415 at the contact rib, to confirm the position of rotation of driven gear 410, rotate at driven gear 410 under the state in precalculated position, prevent that driven gear 410 from touching bar 440.Here, about bar 440 with contact the description that rib 413 do not contact with each other and mean: confirm in the groove 415 because the part of bar 440 is placed in, so bar 440 can not touch the bottom of contact rib 413.

In addition, when dust-collector 200 is installed in dust-collector installation portion 170 places, along with bar 440 touches the bottom of contact rib 413, the contact 432 that the bar 440 that exposes by through hole 177 is pushed microswitch 430.In addition, when moving to the precalculated position along with driven gear 410 rotation, along with the part of bar 400 is inserted in the location confirmation groove 415, bar 440 432 is regained from the contact.

Here, when bar 440 was positioned at location confirmation groove 415, microswitch 430 disconnected, and except above-mentioned situation, promptly touches rib 413, and microswitch 430 keeps opening always.

Formed interference at the downside place of gear teeth 416 and prevented groove 417, to prevent when dust-collector 200 is installed and the interference of external fin 178.

Therefore, when dust-collector 200 was installed in dust-collector installation portion 170 places, external fin 179 was positioned to disturb and prevents groove 417 places, and internal-rib 178 is positioned at the place, space that is formed by contact rib 413.

In addition, each gear teeth 416 all has the both sides with the predetermined curvature rounding.Because when dust-collector 200 is installed on dust-collector installation portion 170 places, driven gear 410 couples together with driven wheel 420, so the both sides of the gear teeth 416 of driven gear 410 are being convenient to driven gear 410 and operating being connected of gear 420 of rounding.

In addition, all form pair of angled plane 419, so that being connected of driven gear 410 and driven wheel 420 at each downside place of gear teeth 416.This intersects each other to the center of clinoplain 419 at gear teeth 416.

Because said structure, with when driven wheel 420 is connected, along with the slip of the gear teeth of the clinoplain 419 of gear teeth 416 and driven wheel 420, driven gear 410 and driven wheel 420 are joined to one another exactly at driven gear 410.

Here, the form of gear tooth of driven wheel 420 becomes the gear-teeth shapes corresponding to driven gear 410, and has omitted the detailed description to driven wheel.

Figure 11 is the block diagram according to the control device of vacuum cleaner of the present invention.

With reference to Figure 11, vacuum cleaner according to the present invention has basically: control module 810; Operation signal input block 820 is selected the suction power (for example strong, the weak pattern of neutralization) to dust; Dust empties signal display unit 830, comes display notification to outwell the signal of the time of the dust of collecting in dust-collector 200 by the light-emitting component such as LED; Suck motor driver 840, operation is as the suction motor 850 of operating electrical machines, with according to the operator scheme by 820 inputs of operation signal input block (for example strong, neutralization is weak), dust absorbed the inside; Compression motor driver 860, operation is used for compressing the compression motor 870 of the dust that is stored in dust-collector 200; Driven wheel 420 is by compression motor 870 operations; Driven gear 410 is along with rotating with driven wheel 420 engagements; And according to the rotation of driven gear 410 and the microswitch of opening and closing.

Specifically, when the user selects expression to suck strong, the neutralization of power by operation signal input block 820 a little less than during one of pattern, control module 810 controls suck motor driver 840, operate sucking motor 850 corresponding to suction power strong, the weak pattern of neutralization with utilization.That is to say, suck motor driver 850 and utilize basis to operate suction motor 850 from the predetermined suction power of the signal of control module 810 transmission.

Control module 810 is operation compression motor 870 like this, that is: operation compression motor driver 860 when operation sucks motor driver 840; Perhaps after sucking motor driver 840, operation operates compression motor driver 860.

Here, as mentioned above, in order to allow the forward direction of first compression member 270 and back to rotation, can be with synchronous motor as compression motor 870.

Synchronous motor constitutes and only utilizes motor self just can carry out forward direction and back to rotation, and in one direction during electric rotating machine, and when the power that is applied to motor becomes when exceeding the predetermined set value, then the direction of rotation of motor forwards other direction to.

At this moment, the power that is applied to motor is the torque that produces according to first compression member, 270 compression dusts, and when torque reaches the set-point, changes the direction of rotation of motor.

Because synchronous motor is known usually in technical field of motors, so omission is for the detailed description of synchronous motor.And the forward direction and the back that utilize synchronous motor can carry out motor are one of them technological thoughts of the present invention to rotation.

In addition, expectation: even while first compression member 270 reaches when making first compression member 270 not rotate the maximum of compressing dust, first compression member 270 still continues to rotate a scheduled time.

Here, can not allow the maximum of first compression member, 270 rotations represent that torque reaches the situation of set-point.

In addition, when torque reaches the set-point, rotate the power of first compression member 270, the power that promptly is applied to compression motor 870 is cut off and reaches a scheduled time, thereby kept dust compressed state under first compression member, 270 halted states, and through after the scheduled time, provide power, can operate first compression member 270 once more to compression motor 870.

Here, it is the time that torque reaches the set-point because be applied to the break time of the power of compression motor 870, so when operating compression motor 870 once more, the direction of rotation of compression motor 870 becomes with cut-out square before in the opposite direction.

In addition, expectation compression motor 870 rotates first compression member 270 continuously with identical speed on left and right directions, so that easily compress dust.

When as above operating compression motor 870, along with first compression member 270 is rotated and the compression dust front and back continuously.In addition, because the amount of the dust of compression increases in dust-collector 200, so the rotational time of first compression member 270 on left and right directions shortens.Here, the amount of the dust of compression is stored and becomes scheduled volume in being drawn into dust-collector 200, when the rotational time of first compression member 270 on left and right directions becomes less than the scheduled time, control module 810 sends a signal based on above-mentioned information and empties signal display unit 830 to dust, and this signal indication empties the time with dust-collector 200 of collecting dust.

Figure 12 and 13 illustrates the view of opening the state of microswitch when first compression member during near a side of second compression member, with the compression dust, Figure 14 and 15 illustrates the view that disconnects the state of microswitch when first compression member and second compression member are positioned on the straight line, and Figure 16 and 17 is the views that illustrate when first compression member state of unlatching microswitch during near the opposite side of second compression member.

Referring to figs. 12 to 17, when first compression member 270 is positioned on the straight line, be standard when having rotated about 180 ° with second compression member 280, in the present invention, bar 440 is positioned at location confirmation groove 415 places of driven gear 410.In the case, because bar 440 432 separation from the contact, so microswitch 430 becomes disconnection.

Here, for convenience, the position of first compression member 270 that microswitch 430 shown in Figure 14 disconnects is called as normal place.

As shown in figure 13, because rotate from normal place rightabout in the clockwise direction in first compression member 270, when compressing the dust in the dust-collector main body 210, bar 440 touches the contact rib 413 of driven gear 410, so bar 440 push contacts 432, thereby microswitch 430 becomes unlatching.

When first compression member 270 of rotating on the rightabout that makes owing to dust in the clockwise direction can not be rotated again, first compression member 270 was rotated in the clockwise direction.Therefore, as shown in figure 16, after by normal place shown in Figure 14, first compression member 270 is rotated on the dextrad of second compression member 280, the dust in the compression dust-collector main body 210.

In addition, when making that owing to dust first compression member 270 of rotating in the clockwise direction can not be rotated again, compression motor 870 is such as repeating above-mentioned process, and rotation first compression member 270 makes that the dust in the dust-collector is compressed on the rightabout in the clockwise direction.

Figure 18 is the view that the whole operation of first compression member shown in Figure 12 to 17 is shown.

Shown in Figure 18: first compression member 270 is from normal place, and rotation is returned and reached the needed time T D1 of normal place in the clockwise direction; With first compression member 270 from normal place, rotation is returned and is reached the needed time T D2 of normal place on the rightabout in the clockwise direction.For convenience, time T D1 is called as first time of return, and time T D2 is called as second time of return.Usually, because dust is dispersed in the dust-collector main body 210 equably, so the first time of return TD1 and the second time of return TD2 are much at one.

On the other hand, the amount of dust of being compressed by first compression member 270 becomes many more, and then time of return TD1 and TD2 become short more.

In the present invention, when one of time of return TD1 and TD2 reach predetermined standard time, determine to have stored enough dusts in dust-collector 210, demonstration will be outwelled the signal of dust.

Now will be in detail with reference to operation and dust compression process according to vacuum cleaner of the present invention.

Figure 19 is the flow chart that illustrates according to the control method of vacuum cleaner of the present invention.

With reference to Figure 19, user's operating vaccum suction cleaners is chosen on the operation signal input block 820 one in the suction power of show strong, the weak pattern of neutralization.Then, control module 810 operations suck motor driver 840, operate sucking motor 850 (S110) according to the suction pattern of being selected by the user.

When operation sucks motor 850, utilize the suction power that sucks motor 850, suck dust by suction nozzle.Then, suck unit 110 by the suction nozzle inhaled air by main body and flow in the main body of dust collector 100, and the air that flows into is along with being inhaled in the dust-collector 200 by some paths.

Specifically, by first air intlet 218 of dust-collector main body 210, towards the contact wire suction dust laden air of the first cyclone unit 230.In addition, suck air, and air and dust be owing to weight differential is subjected to different centrifugal force along with the inner circumferential surface circulation time along the first cyclone unit 230 falls, thus separated from one another in this step.

In addition, after the hole 262 by filter component 260 is filtered,, will be discharged into outside the dust-collector 200 with dust separating air by the steam vent 251 and first air outlet slit 252.

On the other hand, in the step that the inner circumferential surface along the first cyclone unit 230 rotates, the dust of separating is drawn in the dust path of navigation 232 towards contact wire.

In addition, when the flow direction that changes in dust path of navigation 232, the dust that sucks in the dust path of navigation 232 is mobile along the external peripheral surface of the first cyclone unit 230, and along with falling to being stored in the first dust storage part 214 by exporting 234.

Be inhaled in the main body of dust collector 100 by first air outlet slit, 252 air discharged.Suck the air in the main body of dust collector 100,, be inhaled in the second cyclone unit 300 by after the access path 114.

In addition,, air is directed to the contact wire of the inwall of the second cyclone unit 300 by second air intlet of unshowned, as to be connected to access path 114 end, and again with dust separation.

In addition, be inhaled in the main body of dust collector 100 with dust separating air again.Then, suck the air in the main body of dust collector 100, by after sucking motor, the main body outlet by main body of dust collector 100 is discharged into the outside.

On the other hand, the dust of separating is drawn in the dust-collector 200 by dust import 254, and finally is stored in the second dust storage part 216.

In the aforesaid process of dust be stored in the dust storage part after air separation is come out that comprises in air, compression member is stored in dust in the first dust storage part 214 to 270 and 280 compressions.

That is to say that control module 810 operation compression motors 870 are stored in dust (S120) in the dust-collector main body 210 with compression.

Here, the present invention adopts the method for operating compression motor 870 after operation sucks motor 850, still, as another preferred embodiment, can operate sucking motor 850 and compression motor simultaneously.

In addition, when operation compression motor 870, rotated the operation gear 420 that is connected with compression motor 870.When rotary manipulation gear 420, driven gear 410 is connected with operation gear 420, thereby is rotated.When rotation driven gear 410, first compression member 270 that is connected with driven gear 410 is automatically towards 280 rotations of second compression member, compression dust.

Here, control module 810 checks whether first compression member 270 is positioned at normal place place (S130).Because the present invention utilizes the normal place of first compression member 270 to measure first and second times of return as normal place, so when operating for the first time, need check whether first compression member 270 is positioned at the normal place place.First compression member 270 be positioned at the normal place place be illustrated in first when operation the time point that turn-offs for the first time of microswitch 430.

Therefore, control module 810 is measured first and second times of return with the time point that microswitch 430 turn-offs for the first time as standard.

In addition, control module 810 as on first compression member 270 rightabout in the clockwise direction of standard or motion in the clockwise direction, is measured the first time of return TD1 and the second time of return TD2 (S140) according to the time point that moves to normal place from first compression member 270.

Here, along with being increased by the amount of the dust of first compression member 270 in the dust-collector main body 210 and 280 compressions of second compression member, the time of return on left and right directions shortens.

The first time of return TD1 and the second time of return TD2 that control module 810 is measured by first compression member 270 of microswitch 430 judge whether the first time of return TD1 or the second time of return TD2 reach predetermined standard time.Here, be the time that is provided with in control module by the designer predetermined standard time, and become judgement this predetermined standard time and be stored in benchmark in the dust memory main body 210 more than the dust of scheduled volume.This standard time by the designer repeatedly repeated experiments obtain, and dissimilate according to the capacity of vacuum cleaner.

In the present invention, adopt when one of them of the first time of return TD1 or the second time of return TD2 reaches the standard time and judge that amount of dust reaches the method for scheduled volume, yet, as another preferred embodiment, can all reach the scheduled time as the basis of judging with the first time of return TD1 and the second time of return TD2.

As the judged result in step S150, if any one among the first time of return TD1 and the second time of return TD2 all is longer than the standard time, then turn back to step S140, and carry out the process of front.

On the contrary, if the first time of return TD1 or the second time of return TD2 reach the standard time, then control module 810 controls no longer suck dust, turn-off simultaneously and suck motor 850 (S160).Here, the reason of forcing to stop to suck motor is: because when the amount of dust in dust-collector main body 210 during more than scheduled volume, if continue forcibly dust is sucked operation, then the dust suction efficiency reduces, and suck motor 850 and transship.At this moment, expectation is turn-offed and is sucked motor and compression motor 870.

Then, the time that control module 810 notifies the user to outwell dust, transmit a signal to dust and empty signal display unit 830, this signal indication is outwelled the time (S170) of dust in the dust-collector main body 210.As another preferred embodiment of the present invention, can utilize predetermined acoustical signal, such as using buzzer circuit, show that dust outwells signal.

Vacuum cleaner according to the present invention has some advantages, and these advantages are: be informed to the user because empty the time of the dust-collector 200 with dust, so improved user convenience; And because of controlling the operation that sucks motor in the process that empties informing function at the execution dust-collector, so prevented the reduction of the operating efficiency of the dust catcher that excessive dust sucks.

On the other hand, the technological thought of the invention described above can be applied to erect type dust catcher or robot cleaner.
