As shown in Figure 2, tumbling-box washing machine has control part 30.This control part 30 makes the set information of being inputted via input configuration part 31 by user be shown in display part 32, and the operating state based on set information and each portion monitors to control a series of running action of whole washing, rinsing, dehydration procedure.

Control part 30 for example can be by not shown CPU (Central Processing Unit: CPU), stored program ROM (Read Only Memory: read-only storage), in the time carrying out various processing, RAM (Random Access Memory: random access memory), the input/output interface of storage program, data and the bus that they are connected form.

In addition, control part 30 has timer 33.As timer 33, can be used as the built-in function in the action of control part 30 and the internal timer installed.In addition, as timer 33, can also 30 points of timer devices that are arranged of use & Control portion.

In tumbling-box washing machine, utilize rectifier 41 to carry out rectification to alternating electromotive force 40, afterwards, utilize the smoothing circuit being formed by choking-winding 42 and smmothing capacitor 43 to carry out smoothing.Then,, using carrying out direct current power that smoothing obtains as driving electric power, utilize inverter circuit 44 to be rotated driving to drum driven motor 4.

The monitor message of the operating condition that the running of control part 30 based on inputting from input configuration part 31 indicated and detected by each test section carrys out the rotation of index drum drive motor 4.And control part 30 is controlled the action of the required loads such as feed water valve 6, heating part 9, draining valve 11, circulating pump 16 via load driving part 45.

Drum driven motor 4 for example can be configured to DC Brushless Motor, and this DC Brushless Motor possesses and has the stator of three phase winding 4a, 4b, 4c and the rotor of the bipolar permanent magnet of tool, and is provided with three position detecting element 27a～27c.Can utilize inverter circuit 44 to be rotated control to this drum driven motor 4, this inverter circuit 44 is configured to and can carries out PWM control by switch element 44a～44f.

At this, the detected rotor-position detection signal of position detecting element 27a～27c is imported into control part 30.Then, control part 30 is exported control signal based on rotor-position detection signal to inverter driving circuit 46, and connection, off-state via inverter circuit 44 to switch element 44a～44f are carried out PWM control.

By like this, control part 30 is controlled the three phase winding 4a to stator, the energising of 4b, 4c, and the rotor of drum driven motor 4 is rotated with the rotating speed of expecting.In addition, when the state of the signal of any position detecting element in three position detecting element 27a～27c changes, control part 30 all detects its cycle, is gone out the rotating speed of rotor by the rotating speed test section 34 as built-in function according to this computation of Period.And there is following functions: the current signal that drum driven motor 4 is flow through in 35 detections of cloth amount test section judges that the weight of cylinder 3 is the weight of washings.

Below, with reference to Fig. 3 A, Fig. 3 B, action and the action effect of the tumbling-box washing machine forming are as described above elaborated.

In the time washings being put into cylinder 3 and started to wash, control part 30 detects the amount (S1) of washings.The size of the current signal of the drum driven motor 4 while cylinder 3 being rotated together with washings to index drum drive motor 4 detects, and carries out thus the detection of the amount of this washings.

Decide basic output according to the amount of this washings.For example, when the amount that is judged as washings is during for " lacking ", " low " water level WL1 is made as to designated water level.When the amount that is judged as washings for " in " time, will " in " water level WL2 is made as designated water level.In addition, when the amount that is judged as washings is during for " many ", " height " water level WL3 is made as to designated water level (step S2).

Then, control part 30 is opened feed water valve 6 (step S3), and tank 2 and cylinder 3 are supplied water until reach designated water level (step S4).

Between delivery period, by control part 30 controlled circulation pumps 16, make the washings supplied with together with washing agent via circulation waterway 15 from ejiction opening 14 to the interior circulation of cylinder 3, promote thus detergent dissolution in water.Be ejected into cylinder 3 when interior at washings from ejiction opening 14, can cause absorbing water at detergent dissolution clothing before water, therefore, expect that the rotating speed of circulating pump 16 is weak to be less ejected into the degree in cylinder 3 to recirculated water.

Then, in the time reaching designated water level, (step S4 is "Yes"), closes feed water valve 6 (step S5), make cylinder 3 low speed rotation while start stir (S6).The rotating speed of cylinder 3 preferably washings can not attach due to centrifugal force the rotating speed of this degree of internal perisporium face of cylinder 3, so that washings is lifted upward cylinder 3 is interior, fall from the top of cylinder 3 due to Action of Gravity Field, kinetic energy while falling is applied to washings effectively, the rotating speed of cylinder 3 also depends on the amount of washings, but is preferably below 50rpm.Direction of rotation can be both same direction, also can switch positive and negative rotation.

Now, carry out controlled circulation pump 16 by control part 30, the washings that are fully dissolved with washing agent are recycled in cylinder 3 from ejiction opening 14 via circulation waterway 15, promote thus the infiltration of washings to washings.Therefore, thus by the rotating speed of circulating pump 16 be made as can make washings be recycled in cylinder 3 and reliably ejection be easy to make washings to be penetrated into the rotating speed in washings.

When from cylinder 3 starts low speed rotation for example, during through the stipulated time (two minutes) (S7 is "Yes"), dirt sensor 18 detects dirt amount (S8).Control part 30 is determined dirt amount according to the output of dirt sensor 18.With dirt sensor, to detect period of dirt be dirt stripping to the time in washings.

For example, if the output of dirt sensor 18 is setting A (100) above (S9 is "Yes"), parameters R is made as to 300rpm (S10), for example, if the output of dirt sensor 18 is setting B (50) above (S11 is "Yes"), parameters R is made as to 200rpm (S12), (S11 is "No") if not so, is made as parameters R 150rpm (S13).That is to say, the output valve of dirt sensor 18 is larger, and the value of parameter is established greatlyr.

Afterwards, make cylinder 3 carry out High Rotation Speed (S14) with the rotating speed of the parameters R set as described above.Utilization makes cylinder 3 high-speed rotaries then the centrifugal force of generation makes washings become the state attaching along the wall direction of cylinder 3, and the open-work 21 that the moisture containing in washings passes through cylinder 3 after quilt twists out is to tank 2 side shiftings.

The speed that makes cylinder 3 High Rotation Speeds need to be more than the 100rpm that can moisture contained washings be forced to depart from by centrifugal force.If can be enough to moisture contained washings to force the 150rpm departing from above even more ideal, and more preferably more than 300rpm.

In the present embodiment, the output of rotating speed and detected dirt sensor 18 is correspondingly changed.That is, in the time that dirt is few, do not need to make cylinder 3 High Rotation Speeds to 300rpm, be defined as the few energy-saving operation of power consumption that makes the contained moisture of washings depart from required bottom line 150rpm to carry out drum driven motor 4.

On the other hand, in the time that dirt is many, make cylinder 3 High Rotation Speeds remove dirt material to 300rpm.In addition, the unit operation when carrying out this High Rotation Speed, can be continuous once-through operation, can be also to carry out with the short time operation that the such intermittence of On/Off is carried out repeatedly.

Making in the centrifugal force matting of cylinder 3 High Rotation Speeds, remove and contain near the washings washing agent being formed by surfactant, clothes fiber that are attached to the dirt material of clothes fiber when the agitating procedure of the low speed rotation of carrying out before by centrifugal force, can efficiently dirt material be removed together with washings from fiber.

In addition, in the time of cylinder 3 High Rotation Speed, if utilize circulating pump 16 that washings are sprayed to the washings in cylinder 3, the washings washings that does not also adhere to dirt absorbs effectively, can promote thus the replacing of the washings that contain in clothes fiber.

For the time that makes cylinder 3 High Rotation Speeds, as long as can twist out the washings that contain in washings, can be therefore the shorter time, for example only carry out 30 seconds (S15 is "Yes").

Then, again implement to make the agitating procedure (S16) of cylinder 3 low speed rotation.In this agitating procedure, similarly drive circulating pump 16 with the operation of S6, via circulation waterway 15 from ejiction opening 14 to the interior ejection washings of cylinder 3.Now, cylinder 3 can not attach with washings and be rotated at the rotating speed of this degree of the interior rolling of cylinder 3, make circulating pump 16 drive the timing that sprays washings from ejiction opening 14 can be continuous can be also intermittence.

After the centrifugal force matting that makes cylinder 3 High Rotation Speeds, also proceed to make the agitating procedure of cylinder 3 low speed rotation, the mechanical force that can also again utilize thus the chemical force of washing agent to produce with following the rotation of cylinder 3 is further peeled off dirt material residual in fiber.Dirt material concentration in interfibrous washings is high, worry that dirt material adheres again on fiber, the dirt being surrounded by surfactant but the surfactant that is washed agent adheres to is difficult to again adhere to, on washings, only adsorb the surfactant that is not attached to dirt, therefore, can play a role to residual dirt.

Make time of agitating procedure of cylinder 3 low speed rotation as long as making residual washing agent fully be penetrated into the time in washings, therefore also can not rely on cloth amount and be fixed as the stipulated time.For example, in the present embodiment, finish matting (S17 is "Yes") if be made as from starting for the second time agitating procedure through five minutes, computing, constant table can complete matting less, therefore can alleviate the burden of control part 30.

As mentioned above, the output of dirt sensor 18 is larger, the rotating speed of the cylinder in centrifugal force matting 3 is established highlyer, the amount of the dirt of washings is more thus, more can strongly peel off near the washings that are mixed with washing agent of washings and the dirt that is attached to washing agent, can improve cleaning force.On the other hand, the output of dirt sensor 18 is less, and the rotating speed of the cylinder in centrifugal force matting 3 is established lowlyer, if the amount of the dirt of washings is few thus, can clean with the power consumption of required MIN drum driven motor 4, can realize energy-conservation running.

In addition in the above-described embodiment, exemplified with only implementing the matting of the centrifugal force matting (S14) that once makes cylinder 3 High Rotation Speeds, but be not limited thereto.For example, in the case of the amount of the amount of washings, dirt is many, carry out repeatedly centrifugal force matting (S14) and agitating procedure (S16) by alternate repetition, can increase the frequency of centrifugal force matting (S14) and further strongly peel off dirt.

In addition, in the above-described embodiment, the tumbling-box washing machine that only possesses washing function is illustrated, but the present invention is not limited thereto, can also be applied to the drum-type washing drying machine of the functions/drying that possesses washing function and clothing.

The tumbling-box washing machine of present embodiment possesses: tank, its by elastic bearing in housing; Cylinder, it is arranged in tank in the mode that can rotate; Drum driven portion, it is rotated driving to cylinder; Dirt test section, it detects the dirt of the washings in cylinder; And control part, it is transfused to the output of dirt test section, controls successively cleaning, rinsing and each operation of dewatering.And, matting has agitating procedure and centrifugal force matting, wherein, in this agitating procedure, the low speed that makes cylinder can not attach this degree with washings in cylinder is rotated, in this centrifugal force matting, the high speed that makes cylinder can become the state of the internal perisporium face that attaches cylinder with washings is rotated, and discharges washings by centrifugal force from washings.And control part correspondingly changes the rotating speed of the cylinder in centrifugal force matting and the dirt being detected by dirt test section.Thus, can make the rotating speed of the cylinder in centrifugal force matting and the dirt being detected by dirt test section correspondingly change, in the time that the dirt of washings is many, can make rotating speed accelerate and peel off dirt efficiently and improve cleaning force, in the time that the dirt of washings lacks, can make rotating speed slow down to suppress the power consumption of drum driven motor and reduce power consumption.

In addition, in the tumbling-box washing machine of present embodiment, the amount of the dirt being detected by dirt test section is more, control part is established highlyer by the rotating speed of the cylinder in centrifugal force matting, thus can be in the time that dirt be dissolved in fully washings and reaches capacity from washings, make cylinder high-speed rotary transfer further to peel off dirt from washings, can improve cleaning force.

In addition, the tumbling-box washing machine of present embodiment possesses the moisture portion that makes washings contain washings, and washings are contained make washings in centrifugal force matting in moisture portion, can make thus washings act on and attaches the dirt of washings and improve cleaning force.

In addition, the tumbling-box washing machine of present embodiment impregnated in a part for washings to accumulate in the washings of the bottom in tank and make a part for washings moisture, make thus washings effectively absorb the washings that also do not adhere to dirt, can promote the replacing of the washings that contain in clothes fiber and improve cleaning force.

In addition, in the tumbling-box washing machine of present embodiment, be configured to and aspirate the washings of the bottom that accumulates in tank and be ejected into the circulated sprinkling portion on the washings in cylinder, only carry out thus the control of circulating pump and just can carry out the circulation of washings, therefore the cleaning control that can conventionally control cleaning force with the rotation control current etc. that utilize cylinder independently makes washings circulate, can make washings effectively absorb the washings that also do not adhere to dirt, promote the replacing of the washings that contain in clothes fiber and improve cleaning force.

In addition, in the tumbling-box washing machine of present embodiment, as its dirt test section, use at least more than one the sensor in turbidity transducer, conductivity sensor, color (fading) sensor to detect, can tackle thus with washings in the corresponding high-precision dirt of various dirt compositions that contains detect and clean accordingly with dirt.

In addition, the clothing that the tumbling-box washing machine of present embodiment possesses having washed carries out dry drying section, can correspondingly realize the drum-type washing drying machine that cleaning force is high and power consumption is few with the dirt amount of washings thus.

Be provided with multiple projection bodies 116 at the internal perisporium of cylinder 101.By making cylinder 101 low speed rotation, clothing is tangled and is lifted upward by projection body 116.Afterwards, clothing falls from suitable height.Like this, can utilize projection body 116 to stir action (tumbling action).

In addition, be provided with multiple open-works 117 at the internal perisporium of cylinder 101, can make water freely contact between cylinder 101 and tank 102.

As shown in Figure 5, tumbling-box washing machine has control part 170.The set information of being inputted via input configuration part 130 by user is shown in display part 131 by control part 170, and the supervision situation of the operating state based on set information and each portion is controlled a series of running actions of whole cleaning, rinsing, dehydration.

Control part 170 for example can be by not shown CPU (Central Processing Unit), stored program ROM (Read Only Memory), RAM (Random Access Memory), the input/output interface of storage program, data and the bus that they are connected form while carrying out various processing.In addition, control part 170 has detergent amount judging part 132 and timer 171.Detergent amount judging part 132 judges the amount of input washing agent.For timer 171, be used as the built-in function in the action of control part 170 and the internal timer installed.In addition, as timer 171, also can 170 points of timer devices that are arranged of use & Control portion.

In the tumbling-box washing machine of present embodiment, utilize rectifier 124 to carry out rectification to alternating electromotive force 120, utilize afterwards the smoothing circuit being formed by choking-winding 125 and smmothing capacitor 126 to carry out smoothing.Then,, using carrying out direct current power that smoothing obtains as driving electric power, utilize inverter circuit 122 to be rotated driving to drum driven motor 103.The monitor message of the operating condition that the running of control part 170 based on inputting from input configuration part 130 indicated and detected by each test section carrys out the rotation of index drum drive motor 103.And control part 170 is controlled the action of the required loads such as feed water valve 105, draining valve 107, circulating pump 112 via load driving part 123.

Drum driven motor 103 for example can be configured to DC Brushless Motor, this DC Brushless Motor possesses and has the stator of three phase winding 103a, 103b, 103c and the rotor of the bipolar permanent magnet of tool, and is provided with three position detecting element 127a～127c.Can utilize inverter circuit 122 to be rotated control to this drum driven motor 103, this inverter circuit 122 is configured to and can utilizes switch element 122a～122f to carry out PWM control.At this, the detected rotor-position detection signal of position detecting element 127a～127c is imported into control part 170.Then, control part 170 is exported control signal based on rotor-position detection signal to inverter driving circuit 121, and connection, off-state via inverter driving circuit 121 to switch element 122a～122f are carried out PWM control.By like this, control part 170 is controlled the three phase winding 103a to stator, the energising of 103b, 103c, and the rotor of drum driven motor 103 is rotated with the rotating speed of expecting.In addition, when the state of the signal of any position detecting element in three position detecting element 127a～127c changes, control part 170 all detects its cycle, is calculated the rotating speed of rotor by the rotating speed test section 172 as built-in function according to this cycle.

And, also there is following functions: cloth amount test section 173 detects the current signal that flows through drum driven motor 103 and judges the weight of cylinder 101, the i.e. weight of washings.

Below, with reference to Fig. 6 A, Fig. 6 B, action and the action effect of the tumbling-box washing machine forming are as described above elaborated.

In the time washings is put into washing machine starting to wash, the cloth amount test section 173 of control part 170 detects the amount (S1) of washings.The size of the current signal of the drum driven motor 103 while cylinder 101 being rotated together with washings to index drum drive motor 103, acceleration, acceleration time etc. are detected, and carry out thus the detection of the amount of this washings.

Decide basic output according to the amount of this washings.For example, the amount that is judged as washings when cloth amount test section 173 is during for " lacking ", and " low " water level WL1 is made as designated water level by control part 170.When amount that cloth amount test section 173 is judged as washings for " in " time, control part 170 will " in " water level WL2 is made as designated water level.In addition, the amount that is judged as washings when cloth amount test section 173 is during for " many ", and " height " water level WL3 is made as designated water level (step S2) by control part 170.

Then, control part 170 is opened feed water valve 105 (step S3), and tank 102 and cylinder 101 are supplied water until reach designated water level (step S4).

Then, in the time reaching designated water level, (S4 is "Yes"), closes feed water valve 105 (S5), and detergent amount judging part 132 is determined detergent amount (S6).

In the time driving circulating pump 112, cylinder 101, can absorb washings at detergent dissolution clothing before water, be therefore desirably in and drive them to implement the judgement of detergent amount before.Or, also can drive circulating pump 112 to make detergent concentration evenly judge detergent amount with the rotating speed that can not make washings be ejected into this degree of clothing.

If the judged result of detergent amount judging part 132 is the detergent amounts (S7 is "Yes") below setting A, parameters R (rotating speed when cylinder High Rotation Speed) is made as to 300rpm (S8).If judged result is to be greater than setting A and for 1.2 times of setting following detergent amounts (S9 is "Yes"), parameters R to be made as to 200rpm (S10).(S9 is "No") if not so, if judged result is the detergent amount more than 1.2 times than setting A, is made as parameters R 150rpm (S17).That is to say, the detergent amount of being judged by detergent amount judging part 132 is fewer, and the value of parameters R is established greatlyr.By like this, the rotating speed that reduces High Rotation Speed in the time that detergent amount is many suppresses the power consumption of drum driven motor, improves thus energy-efficient performance.In addition, many at detergent amount and under state that detergent concentration is high, reduce the rotating speed of the High Rotation Speed of cylinder, therefore can reduce the generation of abnormal foam.On the other hand, in the time that detergent amount is few, improves the rotating speed of High Rotation Speed and can make cleaning fluid act on efficiently the dirt of clothing, improve cleaning force.

Then, start to make cylinder 101 can not attach the agitating procedure (S12) of the low speed rotation of this degree at the interior washings of cylinder 101.The rotating speed of cylinder 101 is rotating speeds that washings can not attach due to centrifugal force this degree of wall of cylinder 101, so that washings is picked up and is fallen by Action of Gravity Field from the top of cylinder 101 in cylinder 101, effectively applies the kinetic energy while falling.Rotating speed now also depends on the amount of washings, but is preferably below 50rpm.Direction of rotation can be same direction, also can switch termly.

Now, carry out controlled circulation pump 112 by control part 170, by making to be fully dissolved with the washings of washing agent, via circulation waterway 111, the circulated sprinkling portion in ejiction opening 110 is circulated to cylinder 101 promotes that washings are penetrated into washings.Therefore, the rotating speed of circulating pump 112 is made as and recirculated water can be ejected into reliably in cylinder 101 and be easy to make washings to be penetrated into the rotating speed in washings.In addition, the washings in cylinder 101 is impregnated into the washings of the inner bottom part that lodges in tank 102.Be rotated by cylinder 101, washings entirety is flooded repeatedly, repeatedly carries out the moisture of washings and dehydration, thereby promotes the infiltration of washings to washings.

For example, after the set time (two minutes) (S13 is "Yes"), carry out centrifugal force matting (S14).About rotating speed now, carry out High Rotation Speed with the rotating speed of the parameters R of above-mentioned setting.

By the centrifugal force that makes cylinder 101 high-speed rotaries then produce, washings becomes the state attaching along the wall direction of cylinder, and the open-work 117 that the contained moisture of washings passes through cylinder 101 after quilt twists out is to tank 102 side shiftings.

The speed of cylinder 101 High Rotation Speeds is at least needed be moisture contained washings to be forced by centrifugal force the 100rpm departing from.If can be enough to moisture contained washings to force the 150rpm departing from even more ideal above, and more preferably more than 300rpm.

But, as mentioned above, rotating speed and the detergent amount of being judged by detergent amount judging part 132 are correspondingly changed., when detergent amount many (detergent concentration of washings is high), High Rotation Speed is not defined in to 300rpm and makes the contained moisture of washings depart from required bottom line 150rpm to carry out the energy-saving operation that motor power consumption is few.On the other hand, when detergent amount few (detergent concentration of washings is low), High Rotation Speed promotes the replacing of the cleaning fluid containing in washings effectively to 300rpm.In addition, the unit operation when carrying out this High Rotation Speed, can be continuous once-through operation, can be also to carry out with the short time operation that the such intermittence of On/Off is carried out repeatedly.

Making in the centrifugal force matting of cylinder 101 High Rotation Speeds, remove and contain near the washings washing agent being formed by surfactant, clothes fiber that attach the dirt material of clothes fiber when the agitating procedure carrying out before by centrifugal force.Can efficiently dirt material be removed together with washings from fiber thus.And if utilize the washings ejection washings of circulating pump 112 in cylinder 101 in the time of High Rotation Speed, the washings washings that does not also adhere to dirt absorbs effectively, can promote thus the replacing of the washings that contain in clothes fiber.

For the time of centrifugal force matting, as long as can twist out the washings that contain in washings, can be therefore the shorter time, be for example made as and only carry out 30 seconds (S15 is "Yes").

Then again implement to make the agitating procedure (S16) of cylinder 101 low speed rotation.In this operation, similarly start circulating pump 112 with the operation of S12, via circulation waterway 111 from ejiction opening 110 to the interior ejection washings of cylinder 101.Now, cylinder 101 does not attach with washings and is rotated at the rotating speed of this degree of the interior rolling of cylinder 101, the timing that makes circulating pump 112 running spray washings from ejiction opening 110 can be continuous can be also intermittence.

After the operation that makes cylinder 101 High Rotation Speeds, also proceed agitating procedure, the mechanical force that can also again utilize thus the chemical force of washing agent to produce with following the rotation of cylinder 101 is further peeled off dirt material residual in fiber.Dirt material concentration in interfibrous washings is high, worry that dirt material adheres again on fiber, the dirt being surrounded by surfactant but the surfactant that is washed agent adheres to is difficult to again adhere to, on washings, only adsorb the surfactant that is not attached to dirt, therefore can make the chemical force of washing agent play a role to residual dirt.

Afterwards, confirm from starting the agitating procedure centrifugal force matting through five minutes time (S17 is "Yes") at timer 171, stop the rotation of cylinder 101 and matting finishes.

The time of the agitating procedure after centrifugal force matting, as long as making residual washing agent fully be penetrated into the time in washings, does not therefore rely on cloth amount and is fixed as the stipulated time.Computing, constant table can complete matting less, therefore can alleviate the burden of control part 170.In addition, in the present embodiment, be made as from starting the agitating procedure centrifugal force matting through five minutes, but also can stipulate time of matting, when from matting starts for example, through the stipulated time, 10 minutes time, finish the agitating procedure after centrifugal force matting.By like this, can extend necessarily matting.

As mentioned above, the detergent amount of being judged by detergent amount judging part 132 is more, more reduce the rotating speed of the cylinder in centrifugal force matting, the power consumption that can change required MIN drum driven motor with the washings that contain in the high washings of detergent concentration and washings is thus cleaned.Therefore, can realize the running that energy saving is high.On the other hand, the detergent amount of being judged by detergent amount judging part 132 is fewer, more improves the rotating speed of the cylinder in centrifugal force matting, can effectively promote thus the replacing of the washings that contain in washings, can improve cleaning force.

In addition in the present embodiment, as detergent amount test section, the test section being made up of is illustrated, but the present invention is not limited thereto turbidity transducer 114.For example, also can be made as by the conductivity sensor of the conductance that detects water and form., during due to the conductance of water and washing agent and water mixed dissolution, the composition of stripping correspondingly changes, and therefore can also be made as the structure that judges detergent amount according to its rate of change.In addition, can also be made as by the chromaticity transducer of the colourity that detects water and form detergent amount judging part 132., during due to the colourity of water and washing agent and water mixed dissolution, the composition of stripping correspondingly changes, and therefore can also be made as the structure that judges detergent amount according to its rate of change.

In addition in the present embodiment, exemplified with the matting of only implementing a centrifugal force matting (S14), but be not limited thereto.For example, in the situation that washings amount is many, can also be made as following matting: carry out repeatedly centrifugal force matting (S14) and agitating procedure (S15) by alternate repetition, can increase cylinder High Rotation Speed operation frequency and more strongly discharge dirt.

In addition, in the respective embodiments described above, the tumbling-box washing machine that only possesses washing function is illustrated, but the present invention is not limited thereto, can also be applied to and possesses the drum-type washing drying machine that possesses roller drying function for the clothing having washed is carried out to dry drying section.

Bottom in tank 202 is provided with the ponding portion 213 that accumulates washings.In this ponding portion 213, be equipped with substantially in parallel heater 214 with the water surface that accumulates in the washings in tank 202, the washings that accumulate in ponding portion 213 can be heated to the temperature (for example, 30 ℃～40 ℃) of the regulation that is suitable for washing.Utilize thermistor equitemperature test section 215 to detect the temperature of ponding portion 213.

Can make the washings that accumulate in the ponding portion 213 in tank 202 be recycled in cylinder 203 by the circulating pump 217 as circulation portions being arranged in circulation waterway 216.Be provided with in the bottom of ponding portion 213 be connected with circulation waterway 216 for aspirating the suction section 218 of washings, be provided with blowing unit 219 on the top of peristome 206 of the front surface side that is arranged at cylinder 203, with towards the interior ejection washings of cylinder 203.

In circulation waterway 216, be provided with transfer valve 220 in the downstream of circulating pump 217, can optionally switch to the circulation waterway 216 being connected with blowing unit 219 and washings are discharged to any in the drainage path 221 outside machine.Cleaning and when rinsing, can, by the washings ejection in from blowing unit 219 to cylinder 203 by circulation waterway 216 of the washings in ponding portion 213, the washings after cleaning and rinsing can be discharged to outside machine by drainage path 221.

The control part 222 being arranged in housing 201 drives drum driven motor 207, feed water valve 210, heater 214, circulating pump 217 and transfer valve 220 etc. and controls successively cleaning, rinsing and each operation of dewatering.

Below, the action to the tumbling-box washing machine forming as described above, effect describe.The door body 223 that opens and closes the front surface side that is arranged on freely housing 201 is opened and washings is put in cylinder 203 from peristome 206, when the power switch (not shown) of making operation portion 224 operation start switch (not shown) and when entry into service, utilize the amount that detects input washings as the weight detecting portion 225 of state-detection portion of state of detecting the washings in cylinder 203, feed water valve 210 moves water supply start.

Preset the water yield according to input cloth amount, washings are supplied in tank 2 with together with washing agent in putting into detergent box 212.In the time detecting by water level detecting portion 226 washings of having supplied with set amount, stop supplying water, head roll drive motor 207.

In matting, utilize drum driven motor 207 to carry out positive and negative rotation driving to cylinder 203, washings in cylinder 203 is lifted and top in cylinder 203 is fallen the water surface and beaten and wash by projection body 204.In the time that the temperature of supplied with washings is low, heater 214 is switched on, the washings of ponding portion 213 are heated to the temperature that is suitable for washing.The heating-up temperature of washings when warm water cleans is generally 30 ℃～40 ℃, if the temperature in the time supplying water heats while being for example the low temperature 10 ℃ below, aspect raising cleaning performance, is being effective.

The washings that accumulate in the bottom of tank 202 are heated by heater 214, are detected the temperature of ponding portion 213 by the temperature detecting part 215 of outer bottom that is arranged at ponding portion 213, are controlled so that washings become predefined temperature by control part 222.Transfer valve 220 is switched to circulation waterway 216 sides by control part 222, and drive circulating pump 217 with predefined rotating speed, the washings of ormal weight are recycled in cylinder 203, thereby can make washings scatter and be penetrated at the interior middle washings being stirred of cylinder 203.

Be ejected in and ponding portion 213, heat obtained warm water and make it rapid permeability in washings from blowing unit 219, can promote thus the dissolving of washing agent, and can strengthen from the effect of clothing separate dirt and improve cleaning performance.

Utilize circulating pump 217 that the washings in ponding portion 213 are recycled in cylinder 203, the water level in tank 202 declines thus.For example, in the time that the temperature of the ponding portion 213 being detected by temperature detecting part 215 exceedes set point of temperature (, 70 ℃), make the rotating speed of circulating pump 217 reduce to reduce the ability that makes washings circulation.

Thus, the internal circulating load of washings reduces, and can make the water level in tank 202 increase.In the time that water level rises, the temperature of ponding portion 213 declines, and is again controlled as the temperature setting.Heater 214 is submerged in the washings of rising, stably maintains design temperature by control part 222.Thereby heater 214 keeps the not water surface from washings to expose and can, to the state of washings heat radiation, can washings be heated to optimum temperature on one side and make it to be recycled in cylinder 203 on one side.

Control part 222 utilizes the cloth matter that judges the clothing that is washed water-soaked in cylinder 203 as the cloth matter judging part 227 of the state-detection portion of the state of the washings in detection cylinder.By cylinder 203 being rotated to the current value that drives the drum driven motor 207 of measuring when rotation, and measure the output torque characteristics of drum driven motor 207.About this output torque characteristic, the rising of the rotating speed of the drum driven motor 207 of known output torque and head roll 203 is risen pro rata, but the rising of torque is according to the weight of the clothing in cylinder 203 and difference.

As is well known, this output torque is proportional with the q shaft current value that DC Brushless Motor is carried out obtaining in the situation of vector controlled, utilize this character to measure the current value of drum driven motor 207, can judge cloth matter according to the output torque characteristics of drum driven motor 207 thus.

Grade according to the output torque characteristics of drum driven motor 207 to this detected current value additional torque value, based on judging the clothes weight of deriving according to the weight of clothing and judge the data of the torque level of the drum driven motor 207 that grade derives according to output torque, carry out the judgement of cloth matter with reference to the cloth matter judgment standard of storing in control part 222.

Owing to being washed, water-soaked absorbs water, weight increases to put into the clothing of cylinder 203.In the situation that cloth matter is cotton class, water absorption rate is high compared with chemical fibre class, and the moisture quantitative change of washings is many, and the difference of therefore utilizing clothing to be washed the variation of the moisture of water-soaked front and back judges the difference of the cloth matter of clothing.
