Then, illustrate the movement of the first embodiment described above.
Electric cleaner 11 secondary cell 25 be sufficiently charged and can normal use in the state of, by according to setting Determine the operation of button 26 and control unit 24 controls the open and close of element 31, controls from secondary cell 25 to powered supplied air The turn on angle of machine 23, electric blowing machine 23 act.Electric cleaner 11 by by electric blowing machine 23 movement generate negative pressure, Dust on ground is sucked together with air.User holds handle 33, by making section port body 36 on the ground forwards, backwards etc. It is mobile, dust is sucked to dust collecting part 22 via section port body 36.In dust collecting part 22, from the dust laden air being inhaled by dust It separates and traps.Air after dust is separated is sucked by electric blowing machine 23, after the electric blowing machine 23 is cooling, by from Scavenging machine main body 15 is vented.Also, if cleaning terminates, stopped by user with the setting instruction of button 26, control unit 24 makes It is reduced from secondary cell 25 to the turn on angle of electric blowing machine 23, stops electric blowing machine 23.
In the present embodiment, control unit 24 monitors secondary cell 25 by voltage detection department 28 and temperature detecting part 29 Voltage and temperature.That is, control unit 24 is based on the information exported from voltage detection department 28 and temperature detecting part 29, to secondary cell 25 Voltage V and the temperature T of secondary cell 25 etc. monitored.
Also, the control unit 24 is as indicating an example in the solid line of Fig. 3, when the movement due to electric blowing machine 23 The voltage V of secondary cell 25 is gradually reduced, and when becoming the 1st voltage V1 or less, the movement of electric blowing machine 23 is forcibly stopped. In addition, the control unit 24 is that movement starts control unit: the voltage V ratio of the secondary cell 25 when acting beginning is as assigned voltage The 2nd voltage V2 it is big when, if by setting button 26 about movement indicated from external input, be controlled such that electricity Dynamic pressure fan 23 starts to act.That is, the control unit 24 of present embodiment is the 2nd voltage V2 or less as the voltage V of secondary cell 25 When, the movement of limitation electric blowing machine 23 starts.For example, as an example indicated in the double dot dash line of Fig. 3, will be secondary In the case that battery 25 charges, control unit 24 starts the movement of electric blowing machine 23, until the time t1 in Fig. 3.Pass through It does so, prevents the electric cleaner 11 in the state that the voltage V of secondary cell 25 is lower from being restarted and secondary cell repeatedly 25 become by the state of overdischarge, that is, deep discharge state, prevent the service life of secondary cell 25 from declining.
1st voltage V1 is the voltage higher than the final discharging voltage of secondary cell 25.In addition, the 1st voltage V1 for example may be used To be set as the low-voltage close with final discharging voltage.In addition, the 2nd voltage V2 is than the 1st voltage V1 high and to compare secondary cell Lower voltages under 25 fully charged state.
In addition, control unit 24 is in the present embodiment, it is the secondary cell at the end of the movement according to electric blowing machine 23 Difference, that is, variation delta of 25 voltage sets the voltage configuration part of the 2nd above-mentioned voltage V2.That is, using right with secondary cell 25 Electric blowing machine 23 has the state of electric current flowing to compare, and as an example indicated in Fig. 3, does not have to electric blowing machine 23 In the state of electric current flowing, due to internal resistance, voltage is higher, in control unit 24, is imagined according to the difference of these voltages secondary The internal resistance of battery 25, and the 2nd voltage V2 is set based on the internal resistance.
Specifically, control unit 24 stops i.e. powered supplied air in the operating for being set button 26 and indicating electric cleaner 11 In the case where the stopping of machine 23, or becomes the 1st voltage V1 or less in the voltage V of secondary cell 25 and forcibly make powered supplied air In the case that machine 23 stops, i.e., the timing stopped in the movement of electric blowing machine 23, two will detected by voltage detection department 28 The voltage V of primary cell 25 remains voltage Va.Voltage Va becomes the electricity in the state of having electric current to flow through electric blowing machine 23 Pressure.In turn, after such as several seconds stipulated time from the stopping, secondary electricity that control unit 24 will be detected by voltage detection department 28 The voltage V in pond 25 is read.The voltage Vp read out becomes to electric blowing machine 23 without the voltage in the state of electric current flowing.It connects , control unit 24 calculates the difference (Vp-Va) of voltage Va and voltage Vp, its calculated value is set as variation delta.Also, control unit 24 set the 2nd voltage V2 according to variation delta.
In turn, the setting about the 2nd voltage V2, also it is further contemplated that the electric feeding detected by temperature detecting part 29 The temperature T of secondary cell 25 at the end of the movement of blower 23.In addition, control unit 24 can also make electric feeding according to variation delta The action current of blower 23 declines.It is described below about these controls.
Then, also referring to flow chart shown in Fig. 4, above-mentioned movement is explained in detail.
In step sl, control unit 24 obtains the voltage of secondary cell 25 by voltage detection department 28 and temperature detecting part 29 V, temperature T, and obtain the output from setting button 26.
Then, in step s 2, control unit 24 judges whether to output action request from setting button 26.In step S2 In, in the case where being judged as the request of no output action, returned to step S1.On the other hand, it in step S2, is controlling Portion 24 is judged as output action request in the case where, in step s3, control unit 24 judge secondary cell 25 voltage V whether It is bigger than the 2nd voltage V2.In step S3, in the case where control unit 24 is judged as that voltage V is big unlike the 2nd voltage V2, Xiang Bu Rapid S1 is returned.On the other hand, in step S3, in the case where control unit 24 is judged as that voltage V is bigger than the 2nd voltage V2, In Control unit 24 sets the action current of electric blowing machine 23 in step S4.
In step S4, control unit 24 sets the action current of electric blowing machine 23.The action current is set as and moves The corresponding electric current of operation mode, but according to the voltage of secondary cell 25 V, that is, discharge capacity or surplus, it can also make in previous The variation delta of used time measurement is corresponding and makes current reduction.That is, in the biggish situation of variation delta, if electric blowing machine 23 Action current it is larger, then the decline of biggish voltage occurs.Accordingly it is also possible to by making electric blowing machine 23 according to variation delta Action current reduce, inhibit voltage decline, inhibit or prevent from for example connecing with the voltage V of secondary cell 25 and the 2nd voltage V2 Close state makes the case where movement of electric blowing machine 23 inferior deep discharge.The discharge capacity of secondary cell 25 can also be based on example Indicate the voltage V of secondary cell 25 pre-stored data corresponding with discharge capacity or table such as to predict.In the case, Such as the secondary cell 25 before can both being started according to the movement of electric blowing machine 23 voltage V and variation delta and variable setting Action current can also be switched to preset action current.At this point, for example the action current for having electric blowing machine 23 not In the case where same multiple action modes, the action current under the relatively large action mode of action current both can at least be made to drop It is low, it can also only permit the movement under the relatively small action mode of electric current, limit under the relatively large action mode of electric current Movement.In addition it is also possible to which no matter how action mode all reduces action current.In addition, making electric blowing machine 23 in this way Action current reduce in the case where, such as when secondary cell 25 be full charge when etc. secondary cells 25 become than the 2nd voltage V2 In the case where big defined 3rd voltage, the control for releasing the reduction of the action current of electric blowing machine 23 can also be carried out.
Also, in step s 5, control unit 24 switches over the open and close of element 31, is set in step s 4 with becoming Fixed action current acts electric blowing machine 23.
Then, in step s 6, control unit 24 obtains secondary cell 25 by voltage detection department 28 and temperature detecting part 29 Voltage V, temperature T, and from setting button 26 obtain action request.
In turn, in the step s 7, control unit 24 judges whether the switching request that action mode is outputed from setting button 26. In step S7, in the case where control unit 24 is judged as the switching request for outputing action mode, returned to step S4.Separately On the one hand, in step S7, in the case where control unit 24 is judged as the switching request of no output action mode, in step In S8, control unit 24 judges whether to output stopping request from setting button 26.
In step S8, in the case where control unit 24 is judged as and outputs stopping request, in step s 9, control unit The voltage V of secondary cell 25 is remained voltage Va by 24, stops electric blowing machine 23, is advanced to subsequent steps S11.It is another Aspect, in step S8, in the case where control unit 24 is judged as and does not export stopping request, in step slo, control unit 24 judge whether the voltage V of secondary cell 25 less than the 1st voltage V1.In step S10, it is judged as voltage V in control unit 24 In the case where not less than the 1st voltage V1, returned to step S6.On the other hand, in step S10, judge in control unit 24 For voltage V less than the 1st voltage V1 in the case where, to step S9 advance.
Then, in step s 11, when control unit 24 judges whether to have passed through regulation from the stopping of electric blowing machine 23 Between.In step S11, in the case where control unit 24 was judged as not yet by the stipulated time, step S11 is repeated.Another party Face, in step S11, in the case where control unit 24 is judged as and have passed through the stipulated time, in step s 12, control unit 24 The voltage V (voltage Vp) and temperature T of secondary cell 25 are obtained by voltage detection department 28 and temperature detecting part 29.
Also, in step s 13, control unit 24 is set according to difference (Vp-Va) the i.e. variation delta of voltage Va and voltage Vp Fixed 2nd voltage V2.Thus, in the present embodiment, operating, that is, electric blowing machine 23 of the control unit 24 whenever electric cleaner 11 Movement stop when, calculate variation delta.After step S13, returned to step S1.
In step S13, the 2nd voltage V2 is set in the case where control unit 24 is for example judged as that variation delta is relatively large It is relatively largely fixed, it is set in the case where being judged as that variation delta is relatively small relatively small.In addition, in step s 13, Also it can replace variation delta, it is for example being calculated based on ohm's law based on corresponding with the variation delta or using depositing in advance The internal resistance of the secondary cell 25 of calculating such as table corresponding with variation delta of storage judges.In this case it is desirable in electricity The electric current flowed through in dynamic pressure fan 23.The electric current is the electric current under the action state before the stopping of electric blowing machine 23.That is, by It is corresponding with these action modes and flow in electric blowing machine 23 in the case where electric blowing machine 23 has multiple action modes Electric current it is different, further, since making the automatic mode of current-variable in the dust amount etc. that electric blowing machine 23 corresponds to ground In the case where, the difference of the electric current in electric blowing machine 23 is flowed to according to detection time point, so control unit 24 is based on secondary cell Difference, that is, variation delta of 25 voltage Va and voltage Vp and the electric current of electric blowing machine 23 when the variation delta is detected to set Fixed 2nd voltage V2.Thus, in the present embodiment, the electricity in the setting of the 2nd voltage V2, before movement can also will being stopped The electric current of dynamic pressure fan 23 accounts for.
Also, the 2nd voltage V2 for example also can be set as proportional to variation delta.In addition, the 2nd voltage V2 is for example It can be set as to defined reference voltage plus or minus the voltage proportional to variation delta.In turn, the 2nd voltage V2 can also To carry out weighting corresponding with variation delta to reference voltage.In addition it is also possible to from corresponding and preparatory with the size of variation delta The 2nd voltage V2 is selected in the multiple voltage of setting.At this point, can also be for example regulation or less or regulation or more in variation delta In the case of the 2nd voltage V2 is fixed, only than provide it is big or less than defined situation under keep the 2nd voltage V2 variable.
In addition it is also possible to based on the voltage V pre-stored data corresponding with discharge capacity for indicating secondary cell 25 It predicts the discharge capacity or surplus of secondary cell 25, is corrected the 2nd voltage V2 according to the prediction.
In turn, the setting about the 2nd voltage V2, also it is further contemplated that the electric feeding detected by temperature detecting part 29 The temperature T of secondary cell 25 at the end of the movement of blower 23.That is, in the higher situation of environment temperature or electric blowing machine 23 Movement is waited after just stopping in the higher situation of temperature T of secondary cells 25, and internal resistance relatively becomes smaller, lower in environment temperature The case where or from electric blowing machine 23 movement stop by the time when etc. secondary cells 25 the lower situation of temperature T under, Internal resistance relatively becomes larger, thus for example can also according to the temperature by the difference, that is, variation delta or internal resistance of voltage V or The 2nd voltage V2 of person amendment.Specifically, since the internal resistance of the more big then secondary cell 25 of temperature T is smaller, so working as temperature T It is modified when relatively large, so that the difference of voltage V or internal resistance relatively become larger, i.e. the 2nd voltage V2 is got higher.The amendment was both It can be set as example being weighted according to temperature with temperature proportional, it can also be according to the height of temperature from preparatory The a variety of middle selections set, can also not corrected the 2nd voltage V2 in the case where temperature T is regulation or less or regulation or more, Only than provide it is big or less than defined situation under by the 2nd voltage V2 correct.
As described above, the secondary cell in the first embodiment described above, at the end of the movement based on electric blowing machine 23 The variation delta of 25 voltage V sets the 2nd voltage V2.At the end of the movement of the electric blowing machine 23, due to arriving before it Until in order to electric blowing machine 23 power and discharge secondary cell 25 also temperature T rise, so the inside of secondary cell 25 Resistance relatively becomes smaller, and the variation delta of the difference as voltage V also relatively becomes smaller.Thus, it is set according to the variation delta In the case where 2nd voltage V2, the 2nd voltage V2 be also set to it is relatively low, so the movement of electric blowing machine 23 can be limited It is released with relatively low voltage.Therefore, while deep discharge when avoiding the electric discharge of secondary cell 25, be able to carry out than with Toward the short time use start again, can correspond to for example in the way of cleaning secondary cell 25 voltage V decline and it is electronic The case where pressure fan 23 stops is inferior, wants the user's for starting cleaning etc. again as early as possible because there is the residual of cleaning Demand.
Then, illustrate the 2nd embodiment referring to Fig. 5.In addition, for structure same as the first embodiment described above and work With the identical label of imparting, the description thereof will be omitted.
The timing that 2nd embodiment measures the voltage Va and voltage Vp of the first embodiment described above is electric blowing machine 23 Movement when starting.
That is, control unit 24 is set based on the variable quantity of the voltage for acting the secondary cell 25 when starting of electric blowing machine 23 Fixed the 2nd above-mentioned voltage V2.
Specifically, control unit 24 is in the operation start, i.e. electronic for being instructed to electric cleaner 11 by setting button 26 In the case that the movement of pressure fan 23 starts, i.e., time point before the movement of electric blowing machine 23 starts will be by voltage detecting The voltage V for the secondary cell 25 that portion 28 detects remains voltage Vp.Voltage Vp, which becomes, does not flow through electric blowing machine 23 Voltage in the state of electric current.In turn, after the stipulated time from the movement, control unit 24 will be examined by voltage detection department 28 The voltage V for the secondary cell 25 measured is read.The voltage Va of reading becomes electric current flowed through to electric blowing machine 23 in the state of Voltage.So control unit 24 when setting the 2nd voltage V2, calculates the difference (Vp-Va) of these voltages Va Yu voltage Vp, counted Calculation value imagines the internal resistance of secondary cell 25 according to the variation delta as variation delta, based on variation delta setting the 2nd Voltage V2.
At this point, same as the first embodiment described above, internal resistance both can be calculated for example based on ohm's law, can also Envisioned with table referring to the internal resistance corresponding with variation delta stored or discharge capacity.It is calculated based on ohm's law In the case where internal resistance, need to flow to the electric current in electric blowing machine 23.The electric current is that the movement of electric blowing machine 23 is just opened The electric current under action state after beginning.Thus, it in the present embodiment, can also be rigid by movement in the setting of the 2nd voltage V2 The electric current of electric blowing machine 23 after beginning accounts for.
Then, illustrate these movements also referring to flow chart shown in fig. 5.
In the present embodiment, control unit 24 replace step S9, S11, S12 control and have following step S20~ The control of S22.
After step s 3, in step S20, control unit 24 remains the voltage V detected by voltage detection department 28 Voltage Vp advances to step S4.
In addition, after step s 5, in the step s 21, control unit 24 is by voltage detection department 28 and temperature detecting part 29 The voltage V (voltage Va) and temperature T for obtaining secondary cell 25, keep these voltages V and temperature T.
In turn, instead of step S9 in step S22, control unit 24 stops electric blowing machine 23, to before step S13 Into.
Then, in step s 13, control unit 24 is obtained using the voltage Vp obtained in step S20 and in the step s 21 Voltage Va, the 2nd voltage V2 is set in the same manner as the first embodiment described above.
In this way, in above-mentioned 2nd embodiment, the electricity of the secondary cell 25 when the movement based on electric blowing machine 23 starts The variation delta of V is pressed to set the 2nd voltage V2.When the movement of the electric blowing machine 23 starts, usual secondary cell 25 is and ring The state of border temperature roughly equal so-called sufficiently " cooling down ", becomes larger so the internal resistance of secondary cell 25 is opposite, voltage V Difference, that is, variation delta also opposite become larger.Thus, in the case where setting the 2nd voltage V2 according to the difference of voltage V, the 2nd voltage V2 is also higher with respect to being set to, so the movement limitation of electric blowing machine 23 can release under relatively high voltage.Therefore, Such as in the voltage V by the secondary cell 25 that charges be more than the 2nd voltage V2, and the movement of electric blowing machine 23 is limited and is released from And the case where electric blowing machine 23 will be made to act, is inferior, even if occurring larger since the internal resistance of secondary cell 25 is higher Voltage decline, secondary cell 25 is also difficult to easily become deep discharge state, and can be realized and make than the previous short time Start again.
Alternatively, it is also possible to combine the first embodiment described above with the 2nd embodiment.That is, also can detecte electric blowing machine The variation delta of the voltage V of the secondary cell 25 of the time point of the two when 23 movement starts and at the end of movement.In this situation Under, it can choose the one party such as the greater, smaller or little person in the difference of each voltage V both to set the 2nd electricity V2 is pressed, value etc. after can also being weighted based on the average value of these variation deltas or suitably sets the 2nd voltage V2.
In addition, in the respective embodiments described above, electric cleaner 11 may not possess dust collecting part 22, but it is configured to logical Dust is blown winged air blower etc. by the exhaust for crossing electric blowing machine 23.
In turn, electrical equipment is not limited to electric cleaner 11, also can be right for electric tool of such as electric drill etc. etc. It answers and applies.In the case, it is also able to use other than electric blowing machine 23 and is used as electronic portion such as motor.
At least one embodiment from the description above, when control unit 24 is started based on the movement of electric blowing machine 23 and The variable quantity of the voltage V of the secondary cell 25 of at least some time point at the end of movement sets the 2nd voltage V2, specifically, In the case where variation delta is relatively large, the 2nd voltage V2 is set to relatively high.Therefore, for for example because of the journey of deterioration Degree, the temperature of secondary cell 25 or environment temperature etc. and the internal resistance of different secondary cells 25, can suitably set electricity Dynamic pressure fan 23 can start the 2nd voltage V2 of movement, so as to the greatest extent may be used while inhibiting the deep discharge of secondary cell 25 It can start to act again earlyly.
That is, for example in the case where the internal resistance of secondary cell 25 is relatively small secondary cell 25 can be being avoided While deep discharge, the 2nd voltage V2 is set to it is lower, can release earlier electric blowing machine 23 movement limitation, can Realize that the operating earlier of electric cleaner 11 starts again, and the situation relatively large in the internal resistance of secondary cell 25 Under, the 2nd voltage V2 can be set to it is relatively high, even if in the movement of electric blowing machine 23 due to secondary cell 25 Internal resistance and in the case where the decline of biggish voltage has occurred, be also able to suppress the deep discharge of secondary cell 25 and realize electronic The operating earlier of scavenging machine 11 starts again.
Change to the electric current that electric blowing machine 23 supplies in addition, control unit 24 has and adjust the output of electric blowing machine 23 Function, the electric blowing machine 23 due to the variation delta of the voltage V based on secondary cell 25 and when detecting the variation delta Electric current set the 2nd voltage V2, so the case where multiple action modes, is inferior for example having, according to electric blowing machine 23 It exports in the case where electric current difference, the voltage decline that can also occur for corresponding with respective electric current sets the 2nd voltage V2, so as to start to act as early as possible again while inhibiting the deep discharge of secondary cell 25.
In addition, control unit 24 is corresponding with discharge capacity in advance based on the voltage V for indicating secondary cell 25 by basis The data of storage and the 2nd voltage V2 is set by the discharge capacity of the secondary cell 25 of the voltage V of secondary cell 25 prediction, energy It reaches and further considers the remaining discharge capacity of secondary cell 25 and precision preferably sets the 2nd voltage V2.
In addition, the temperature of the secondary cell 25 at the end of movement of the control unit 24 by further considering electric blowing machine 23 T and set the 2nd voltage V2, can precision the different internal resistance according to temperature T of secondary cell 25 is better anticipated, can Further increase the setting accuracy of the 2nd voltage V2.For example, although the original internal resistance of secondary cell 25 is relatively large, It is also contemplated that due to secondary cell 25, temperature T becomes due to fever in the case wheres equal after the movement of electric blowing machine 23 is rigid High, internal resistance relatively becomes smaller, thus by further consideration temperature T and the 2nd voltage V2 is set to it is relatively high, can It sets the 2nd voltage V2 close to the value based on original internal resistance, is able to suppress the deep discharge of secondary cell 25.
In turn, control unit 24 due to according to electric blowing machine 23 movement start when and movement at the end of at least some when Point secondary cell 25 voltage V variation delta and reduce the action current of electric blowing machine 23, so the 2nd can be set Voltage V2, so as to start to act as early as possible again while inhibiting the deep discharge of secondary cell 25.
That is, such as in the lesser situation of internal resistance in the secondary cell 25 predicted according to the variation delta of voltage V, When the relatively low state of the voltage V of discharge capacity or the less state of surplus, i.e. secondary cell 25 from secondary cell 25 When acting electric blowing machine 23, it is able to carry out the operating exported under lesser action mode or inhibits each action mode Under output in the state of operating, be able to suppress the deep discharge of secondary cell 25.Even if in addition, for example in electric blowing machine 23 Movement limitation just release after the voltage V of equal secondary cells 25 be more than the 2nd voltage V2 and the case where close to the 2nd voltage V2 Under, control unit 24 is also able to suppress voltage decline, so even if by the 2nd by reducing the action current of electric blowing machine 23 Voltage V2 is set to lower, is also able to suppress the deep discharge of secondary cell 25, and electric cleaner 11 can reoperate earlier.
In addition, the 2nd voltage V2 is set whenever the movement of electric blowing machine 23, whenever the operating of electric cleaner 11 It is fixed, so the variation even for the internal resistance of secondary cell 25 also can suitably set the 2nd voltage V2.Thus, for example Even if in the case where the 2nd voltage V2 is set to higher or lower for the time being, if the internal resistance of secondary cell 25 becomes thereafter Change, so that the 2nd voltage V2 is changed every time, so 2nd voltage V2 corresponding with the state of secondary cell 25 can be set.
Also, the electric cleaner 11 for using electric blowing machine 23 as electronic portion by application is using high current Electric cleaner 11 in, can while secondary cell 25 is reliably protected from deep discharge, realize as far as possible in short-term Between use start again.
In addition, in the above-described embodiment, the resistance for being conceived to the secondary cell 25 if secondary cell 25 deteriorates becomes Greatly, the characteristic that drop-out voltage amount when discharging also becomes larger, to speculate the deterioration of secondary cell 25.Be not limited to this, can also with Eye is shortened according to the charging time in the characteristic of the discharge capacity reduction if secondary cell 25 deteriorates to speculate secondary cell 25 Deterioration.That is, electrical equipment can also have the charging time measurement portion of the length in the charging time of measurement secondary cell 25, voltage Configuration part sets assigned voltage based on the variation in the charging time of secondary cell 25.The assigned voltage is whether to allow electronic portion The threshold value that starts of movement, be in the above-described embodiment " the 2nd voltage V2 ".The mode of the setting of assigned voltage It is to become shorter than in the past according to the voltage of secondary cell 25 is improved a certain amount of the spent charging time, so that assigned voltage It is bigger than in the past.
Illustrate several embodiments of the invention, but these embodiments prompt as an example, are not intended to define The range of invention.These new embodiments can be implemented in the form of other are various, in the purport for not departing from invention Various omissions, substitutions and changes are able to carry out in range.These embodiments and modifications thereof be included in invention range or In purport, and it is included in the invention described in the claims and the equivalent range thereof.
