The inverter switch control signal Sic of output is transformed to gate drive signal at door drive division (not shown), inputs to the door of each switch element in the phase inverter 420.Thus, each switch element Sa, S ' a, Sb, S ' b, Sc, the S ' c in the phase inverter 420 carries out switch motion.
In addition, relevant with embodiments of the invention, when inverter controlling portion 430 is detected at washing bag amount, close the electric current of supplying with in (off) motor 230.That is, make all switch element Sa, S ' a, Sb, S ' b, Sc, S ' c in the phase inverter 420 be closed (off).In addition, in the above-mentioned down periods, the geard-down speed or the deceleration time of calculating out through detected position signalling H in the position-based test section 235, thus can detect washing bag amount accurately.
As stated, explained that the inverter controlling portion 430 in the drive division 220 carries out the washing bag amount detection, but this is an example, also can carries out washing bag amount by the control part 210 of the everything of controlling drive division 220 and detect.That is, detected position signalling H passes to control part 210 through drive division 220 in the position detection part 235, and detects washing bag amount by control part 210.
And different with Fig. 3 and Fig. 4, control part 210 can be made up of single unit with inverter controlling portion 430.
Fig. 6 representes the flow chart of the control method of device for processing washings according to an embodiment of the invention, and Fig. 7 to Figure 14 is for the explanation of the control method of Fig. 6 drawing as reference.
Below, will describe with reference to accompanying drawing.At first, when the action of device for processing washings, in order to detect washing bag amount or washing bag matter, turn-on current makes motor carry out rotating the first time S610.And based on the rotation of motor, execution washing bag amount for the first time detects or washing bag quality inspection survey S615.
Control part 210 or inverter controlling portion 430 connect AC power, and control motor 230 carries out the rotation first time with the first certain rotary speed v1.That is, control corresponding inverter switch control signal Sic and export to phase inverter 420.At this moment, the alternating current of connecting in the motor 230 is preferably sine-wave current.Thus, when washing bag amount detected or wash bag quality inspection survey, drive motors 230 accurately.
Illustration goes out in Fig. 7, and at the first interval T1, motor 230 is rotated with the first rotary speed v1.For motor 230 keeps certain rotary speed, the first interval T1 of this moment preferably keeps more than the predetermined time period.And the interval that is used for the washing bag amount detection preferably keeps suitably interval and avoids long.
In addition, illustration goes out in the accompanying drawings, and the interval that is rotated with first rotary speed is 1 time, but is not to be defined in this, and washing bag amount detects or washing bag quality inspection survey in order to carry out accurately, and it can be carried out repeatedly.
Then, the electric current S620 that connects in the disable motor.And, in the down periods,, carry out washing bag amount and detect S625 based on the geard-down speed or the deceleration time of the motor in during at least a portion.
The electric current of connecting in control part 210 or inverter controlling portion 430 disable motors 230.That is, shown in Fig. 8 a, three couples of upper edge switch element Sa, Sb, Sc and lower edge switch element S ' a, S ' b, the S ' c in (turn off) phase inverter 420 broken off in control.Thus, motor 230 will slow down.
In an embodiment of the present invention, detect in order to carry out washing bag amount, the alternating current of supplying with in the disable motor 230 during at least a portion in the down periods, utilizes the geard-down speed or the deceleration time of motor 230, carries out washing bag amount and detects.
When the alternating current supplied with in the disable motor 230, like the second interval T2 of Fig. 7, the motor 230 that is used to drive the Wash tub 120 of accommodating the washing bag will slow down.Particularly, from closing (off) to certain interval, the slowing down of motor 230 non-linear (nonlinear), during certain interval T3, the speed of motor 230 linear (linear's) slows down.In addition, untie along with the washing in the Wash tub 120 encapsulates, motor 230 is slowing down with non-linear (nonlinear) again.
In an embodiment of the present invention, during T3 between above-mentioned linear deceleration area, utilize the geard-down speed or the deceleration time of motor 230, carry out washing bag amount and detect.As stated, geard-down speed or deceleration time that the position signalling H of position-based test section 235 calculates out, detect the geard-down speed or the deceleration time of motor 230.
For example, geard-down speed or deceleration time are long more, and it is little to be judged as washing bag amount, and geard-down speed or deceleration time are short more, and it is big to be judged as washing bag amount.
For example, be under the situation between the 100rpm to 150rpm at the first rotary speed v1 of motor 230, the geard-down speed of the motor between the washing bag amount detection zone is at least a portion between the 30rpm to 90rpm.30rpm (vx) is interval to the geard-down speed between the 90rpm (vy), corresponding to T3 between the linear zone except between above-mentioned inelastic region.Thus, carrying out accurately, washing bag amount detects.
In addition, in the interval T3 of linearity,, can also carry out washing bag amount and detect based on geard-down speed during between a plurality of deceleration areas or deceleration time except based on the geard-down speed during between a part of deceleration area or deceleration time.In addition, also can utilize average or weighted value, calculate final washing bag amount detected value for a plurality of washing bag amount detected values.
In addition, washing bag amount detection for the first time can be based on certain speed rotation (for example, the speed ripple composition in the time of v1), or the execution of the ripple composition of the output current io that flows in the motor of motor 230.
Illustration goes out in Fig. 9, keeps the first certain rotary speed v1 in order to make motor 230, in motor 230, flows when certain electric current I a is arranged, and is produced current ripples composition Ir by flowing of the washing bag in the Wash tub 120.Above-mentioned current ripples composition Ir is big more, detect into washing bag amount big more.
In addition, though not shown, before the rotation first time of motor, can carry out the washing bag dispersion steps in the Wash tub.In above-mentioned washing bag disperseed, the rotary speed v0 of the first rotary speed v1 when detecting to be lower than washing bag amount carried out positive direction rotation or opposite spin or positive direction and reciprocal the stirring repeatedly rotated, and the washing bag is disperseed.
Illustrate among Fig. 7, carry out 2 times certain rotation speed v0 rotation at set interval To, but it just representes the size of speed, and independent of direction.In addition, illustration goes out 2 times certain rotation speed v0 in the accompanying drawing, but also can be 1 time, also can be its above number of times.
Control part 210 or inverter controlling portion 430 control motors 230 are rotated with certain rotation speed v0.That is, control corresponding inverter switch control signal Sic and export to phase inverter 420.
Then, judge whether to be set at energy saver mode S620, if S630 aborts in Wash tub.And, make Wash tub 120 carry out positive rotation or despining or positive and negative stirring rotation S635.
Energy saver mode can be through above-mentioned Fig. 3 the actuating signal of energy-conservation key 116 (eco key) get into.The action that control part 210 can be confirmed energy-conservation key 116 whether.In addition, under the situation of control part 210 energy-conservation key 116 actions when the action of device for processing washings 100, control directly aborts in Wash tub 120, and execution in step S625 not.At this moment, make Wash tub 120 carry out positive rotation or despining or positive and negative stirring rotation.
This is when in Wash tub 120, throwing in the washing bag (wet washing bag) be soaked in water rather than dry washing bag (dry cleaning bag), and carrying out accurately, washing bag amount detects.
Control part 210 is set value when above at detected washing bag amount, based on water level detecting portion 265 detected water level frequencies or water injected volume test section 268 detected water injected volumes, regulates the amount of the water of throwing in the Wash tub 120.
Preferably, when aborting, control it and soak the washing bag in the Wash tub 120.At this, the amount that the washings in the Wash tub 120 encapsulate the water that soaks is higher than the empty water level of Wash tub, is lower than washing bag water level.That is, preferably throw in the water of the degree of only soaking part washing bag.
The water level H2 between empty water level H0 that is equivalent to water jacket 124 and the washing bag water level H1 that washs bag 810 is rendered in the illustration water outlet among Figure 10.When aborting,, throw in from feedwater stream 123 through the control of 210 pairs of water-supply valves 125 of control part.
At this moment, for the water of throwing in soaks the washing bag preferably, 210 pairs of motors 230 of control part are controlled, and make motor 230 carry out positive rotation or despining or positive and negative stirring.
When soaking the washing bag,, the washing bag is soaked through carry out positive direction rotation or opposite spin or positive direction and the reciprocal rotation of stirring repeatedly with the rotary speed v0 that is lower than the first rotary speed v1.
Then, after aborting, in order to detect washing bag amount or washing bag matter for the second time, turn-on current makes motor carry out rotating the second time S640.And based on the rotation of motor, execution washing bag amount for the second time detects or washing bag quality inspection survey S645.
Control part 210 or inverter controlling portion 430 connect alternating current, and control motor 230 carries out the rotation second time with the first certain rotary speed v1.That is, control corresponding inverter switch control signal Sic and export to phase inverter 420.At this moment, the alternating current of connecting in the motor 230 is preferably sine-wave current.Thus, when washing bag amount detects, motor is driven accurately.
Illustration goes out among Fig. 7, and at the 6th interval T6, motor 230 is rotated with the first rotary speed v1.For motor 230 keeps certain rotary speed, the 6th interval T6 of this moment preferably keeps more than the predetermined time period.And, preferably keep during the suitable interval, to avoid being used for the interval long of washing bag amount detection.
In addition, illustration goes out in the accompanying drawing, and the interval that is rotated with the first rotary speed v1 is 1 time, but is not to be defined in this, and for washing bag amount detection accurately, it can be carried out repeatedly.
In addition, the electric current of connecting in control part 210 or inverter controlling portion 430 disable motors 230.That is, shown in Fig. 8 a, three couples of upper edge switch element Sa, Sb, Sc and lower edge switch element S ' a, S ' b, the S ' c in (turn off) phase inverter 420 broken off in control.Thus, motor 230 will slow down.
In an embodiment of the present invention, detect in order to carry out washing bag amount, the alternating current of supplying with in the disable motor 230 during at least a portion in the down periods, utilizes the geard-down speed or the deceleration time of motor 230, carries out washing bag amount and detects.
When the alternating current supplied with in the disable motor 230, like T7 between the SECTOR-SEVEN of Fig. 7, the motor 230 that is used to drive the Wash tub 120 of accommodating the washing bag will slow down.Particularly, from closing (off) to certain interval, the slowing down of motor 230 non-linear (nonlinear), during certain interval T8, the speed of motor 230 linear (linear's) slows down.In addition, untie along with the washing in the Wash tub 120 encapsulates, motor 230 is slowing down with non-linear (nonlinear) again.
In an embodiment of the present invention, during T8 between above-mentioned linear deceleration area, utilize the geard-down speed or the deceleration time of motor 230, carry out washing bag amount and detect.As stated, geard-down speed or deceleration time that the position signalling H of position-based test section 235 calculates out, detect the geard-down speed or the deceleration time of motor 230.
For example, geard-down speed or deceleration time are long more, and it is little to be judged as washing bag amount, and geard-down speed or deceleration time are short more, and it is big to be judged as washing bag amount.
For example, be under the situation between the 100rpm to 150rpm at the first rotary speed v1 of motor 230, the geard-down speed of the motor between the washing bag amount detection zone is at least a portion between the 30rpm to 90rpm.Geard-down speed between the 30rpm to 90rpm is interval, corresponding to T8 between the linear zone except between above-mentioned inelastic region.Thus, carrying out accurately, washing bag amount detects.
In addition, in the interval T8 of linearity,, can also carry out washing bag amount and detect based on geard-down speed during between a plurality of deceleration areas or deceleration time except based on the geard-down speed during between a part of deceleration area or deceleration time.In addition, also can utilize average or weighted value, calculate final washing bag amount detected value for a plurality of washing bag amount detected values.
In addition, the certain rotation speed v1 when for the first time washing bag amount detects in the accompanying drawing when washing bag amount detects for the second time is set at identical speed, but is not to be defined in this, and it can be set at mutual different rotary speed.Certain rotation speed when particularly, washing bag amount detects for the second time can be bigger.
And; In the accompanying drawings; When the first time, washing bag amount detected, when washing bag amount detects for the second time, carry out substantial washing bag amount between the identical deceleration area in the down periods and detect, but can be different therewith carry out washing bag amount in different each other intervals and detect.For example, after aborting, when the second time that the weight in Wash tub increases, washing bag amount detected, carry out washing bag amount at higher speed interval and detect.Thus, detect washing bag amount accurately.
In addition, washing bag amount detection for the second time can be based on certain speed rotation (for example, the speed ripple composition in the time of v1), or the execution of the ripple composition of the output current io that flows in the motor of motor 230.
As stated, illustration goes out in Fig. 9, for motor 230 keeps the first certain rotary speed v1, in motor 230, flows when certain electric current I a is arranged, and is produced current ripples composition Ir by flowing of the washing bag in the Wash tub 120.Above-mentioned current ripples composition Ir is big more, detect into washing bag amount big more.
In addition, control part 210 is surveyed according to the washing bag amount detection second time or the quality inspection of washing bag, calculates the duration of runs of device for processing washings.For example, when washing bag amount is big, increase wash time, scavenging period, dewatering time etc.In addition, when being dry cleaning bag rather than wet washing bag in identical washing bag amount, increase wash time, scavenging period, dewatering time etc.
In addition, the speed when control part 210 can be set running stroke, offset and detects, the acceleration the when rotary speed of motor rises, or the deceleration of the rotary speed of motor when slowing down, or in the maximum rotative speed of motor at least one.
Illustration goes out among Figure 11 b, by the example of the duration of runs that the second time, the washing bag amount detection computations went out.In display unit 118, show the object (object) 840 that is used to represent energy saver mode, the 0:45 duration of runs that demonstration calculates, wash time 0:25, scavenging period 0:10, dewatering time 0:10 etc.Thus, the user confirms the duration of runs that calculates based on washing bag amount detection accurately.Particularly, can reduce unnecessary energy resource consumption.
In addition, when not being set at energy saver mode, after step S620, showing based on detected washing bag amount or washing for the first time and wrap the S625 duration of runs that matter calculates.For the first time from as the dry cleaning bag time, its degree of accuracy may be high at the washing bag for detected washing bag amount or washing bag matter, but at the washing bag from as a part of wet washing bag the time, washing bag amount detects or the quality inspection of washing bag survey may be inaccurate.
Nonetheless, control part 210 is not when being set at energy saver mode, and first control will be presented at display unit 118 based on the duration of runs that the first time, detected washing bag amount or washing bag matter calculated.
Illustration goes out among Figure 11 a, by the example of the duration of runs that the first time, the washing bag amount detection computations went out.Fuzzy demonstration is used to represent the object 840 of energy saver mode in display unit 118, to confirm that energy saver mode is closed
(off)。In addition, the 1:00 duration of runs that demonstration calculates in display unit 118, wash time 0:30, scavenging period 0:15, dewatering time 0:15 etc.
Figure 11 a and Figure 11 b are compared, when being set at energy saver mode, after aborting, carry out washing bag amount detection accurately, can confirm that through Figure 11 b reduce the duration of runs of actual laundering thing treating apparatus on the whole.Thus, when the running of device for processing washings, can reduce consumes electric power.
In addition, after washing bag amount detects S615, S645, can carry out the braking step of the driving that is used to stop motor.For this reason, control part 210 or inverter controlling portion 430 control motors 230 are braked.As braking method, can use dynamic brake, plugging etc.
For example; In order to carry out dynamic brake; Shown in Fig. 8 b, three couples of upper edge switch element Sa, Sb, the Sc in (turn off) phase inverter 420 all breaks off in control part 210 or inverter controlling portion 430, and whole (turn on) lower edge switch element S ' a, S ' b, S ' c of connecting.Thus, form closed circuit (closed loop) between motor 230 inside and lower edge switch element S ' a, S ' b, the S ' c, and the consume residual electric current.Thus, motor 230 will be stopped.
As another example; In order to carry out dynamic brake; Shown in Fig. 8 b, three couples of upper edge switch element Sa, Sb, Sc that control part 210 or inverter controlling portion 430 connect in (turn on) phase inverter 420, and all break off (turn off) lower edge switch element S ' a, S ' b, S ' c.Thus, form between motor 230 inside and upper edge switch element Sa, Sb, the Sc closed circuit (closed loop), and the consume residual electric current.Thus, motor 230 will be stopped.
As another example, in order to carry out plugging, control part 210 or inverter controlling portion 430 insert inverter switch control signal Sic to phase inverter 420, constitute the opposite direction rotation with the direction of rotation with motor 230.Promptly; If during the first interval T1 or the 6th interval T6; The phase place of the alternating current of connecting in the three-phase of motor 230 is the order of a, b, c phase, and in order to carry out plugging, the phase place of the alternating current of connecting in the three-phase of control motor 230 is the order of a, c, b phase.Thus, motor 230 will be stopped through the composition of opposite direction rotation.
Illustration goes out the interval T4 of braking of motor 230 or brakes interval T9 among Fig. 7, can learn that motor 230 is braked in being shorter than the interval of slowing down naturally of motor 230.Thus, can shorten on the whole between the washing bag amount detection zone.
In addition, when device for processing washings was overhead (top load) mode of Fig. 1, control part 210 was after wash time shows, control aborts to water level in Wash tub.Thus, carry out washing stroke.
Figure 12 is the flow chart of method of operating of the device for processing washings of presentation graphs 1.
With reference to accompanying drawing, in the method for operating of device for processing washings, carry out washing stroke S910, clean stroke S920 the duration of runs that calculates among the step S650 based on above-mentioned Fig. 6, and dehydration stroke S930.
During washing stroke S910, carry out between the washing bag amount detection zone of the washing bag amount be used to detect the washing bag in the Wash tub 120, be used to detect between the unbalanced offset detection zone of washing bag, and between main scrubbing section etc., and can implement multiple example.
During cleaning stroke S920, between execution feedwater interval, set speed Rotary District, between the catchment etc., and can implement multiple example.
During dehydration stroke S930; Execution is used to detect between the washing bag amount detection zone of washing bag amount of the washing bag in the Wash tub 120, is used to detect between the unbalanced offset detection zone of washing bag, intermittently between drying zone; And between main drying zone etc., and can implement multiple example.
Figure 13 be the expression Figure 12 washing stroke the time the motor rotary speed one the example drawing.
With reference to accompanying drawing, the washing stroke interval of Figure 13 comprises between Ta between the washing bag amount detection zone, offset detection zone Tc between Tb, first scrubbing section, and Td between second scrubbing section.
Ta is the interval of detecting the washing bag amount in the Wash tub 120 between the washing bag amount detection zone; As shown in Figure 7; Carry out the washing bag amount detection first time based on the rotation first time of motor 230; For soak abort in the washing Bao Erxiang Wash tub 120 after, carry out washing bag amount detection second time based on the rotation second time of motor 230.Thus, except the dry cleaning bag, can also carrying out accurately at the wet washing bag, washing bag amount detects.
Particularly, after making motor 230 carry out the rotation first time or rotation for the second time with certain speed, under the state of the electric current of in disable motor 230, connecting, utilize the geard-down speed or the deceleration time of motor 230, carry out washing bag amount and detect.
In addition, after washing bag amount detects, carry out the motor braking of dynamic brake or plugging, thereby shorten between a part of washing bag amount detection zone.
In addition, according to detected washing bag amount, when washing decision washing water supplied amount, washings water level etc.
