Fig. 6 is the circuit diagram of the main composition of control device in this tumbling-box washing machine of expression.

Control device 30 is by being connected on the commercial power 32 by above-mentioned power switch button 6 operated power switch 6a and sockets 31.This control device 30 in turn through filter circuit 30a and rectification circuit 30b and converter circuit 30c to drum drive motor 13 power supplies.This drum drive motor 13 is dc brushless motors of current transformer type of drive, and be the position of rotation that detects the rotor (omitting diagram) that possesses permanent magnet by position-detection sensor 13b, and produce the formation of torque by make drive current flow to stator (coil) 13c according to this detection position from converter circuit 30c.

The drive motors 16a of washings circulating pump 16 is connected with 30e through three terminal bidirectional switch 30d between filter circuit 30a and rectification circuit 30b.This drive motors 16a is the shaded-pole induction machine, and it constitutes above-mentioned three terminal bidirectional switch 30d, 30e and prevents to make the washings of washings circulating pump 16 discharge characteristic changing because of supply frequency is different by carry out type conversion according to supply frequency (50Hz and 60Hz).

The control program of dress washing, dehydration procedure in the microcomputer 30f, and set the control constant of washing, dehydration procedure according to the washing procedure indication input of the configuration switch group 7a of configuration switch button groups 7 operations that come free guidance panel 3, and according to from the beginning switch 9a of beginning shift knob 9 operations begin indicate input to wash and the control processing of dehydration procedure and the demonstration processing of display floater 8.

Have again, above-mentioned microcomputer 30f, for supply with washings to dress water tank 12 and discharge in the dress water tank 12 washings and with reference to the water level detecting signal controlling driving circuit for electromagnetic valve 30g that exports from water level sensor 26 so that switch electromagnetism feed water valve 20, drain solenoid valve 23; For make rotation drive swing roller 11 drum drive motor 13 runnings and with reference to from the position detection signal of position-detection sensor 13b output and from the input voltage detection signal of the converter circuit 30c of input voltage sensor 30h output and from the input current detection signal control current transformer drive circuit 30j of the converter circuit 30c of input current sensor 30i output so that make converter circuit 30c running; Control three terminal bidirectional switch 30d, 30e for the drive motors 16a running that makes washings circulating pump 16 with reference to the supply frequency detection signal of exporting from frequency detecting sensor 30k.

The tumbling-box washing machine of Gou Chenging cuts out the clothing dress and gets and cover 2 and cut out the clothing gateway 12a of dress water tank 12 after opening clothing gateway 2 and drop into washings 10 in swing roller 11 like this, and the setting of washing procedure is imported in operating and setting shift knob group 7 and indication.

Microcomputer 30f in according to the control constant of the washing of setting washing procedure from the washing procedure of configuration switch group 7a indication input, dehydration procedure on display floater 8 washing procedure of display setting.

And, according to from beginning switch 9a begin indicate input to begin to wash and the control of dehydration procedure is handled.Below, handle to describe by the control of performed washing of microcomputer 30f and dehydration procedure.

At first, in the stage before water supply, control current transformer drive circuit 30j is so that drum drive motor 13 runnings and rotation drive swing roller 11.Detect the cloth amount of washings 10 according to the rising characteristic of the load current characteristic of drum drive motor 13 of this moment and rotating speed, desirable detergent amount is presented on the display floater 8.

The user puts into the washing agent of desired quantity in the washing agent injection mechanism 4, and then, operation beginning shift knob 9 is then opened water supply electromagnetic valve 20 and supplied with running water.This water supply together flows in the swing roller 11 by washing agent injection mechanism 4 and washing agent.Monitor water level in the dress water tank 12 by water level detecting signal, as arrive the predetermined water level L1 of cleaning (depth of water H1) and then close water supply electromagnetic valve 20 from water level sensor 26 output.Then, the running of index drum drive motors 13 is so that swing roller 11 cleans the rotating speed rotation with predetermined.

In case swing roller 11 rotation, the washings 10 that is positioned at swing roller 11 lower curtates is by mentioning at the set hoisting mechanism 11c of these swing roller 11 inner peripheral surfaces and leaving this hoisting mechanism 11c and fall bottom surface when moving to the high position.During swing roller 11 rotation, the motion that repeated washing thing 10 is mentioned and fallen by hoisting mechanism 1c, and clean and wash by falling and clash into bump that mechanical force that swing roller 11 inner faces are produced carries out.

Like this, the cleaning that tumbling-box washing machine carried out is owing to being that the bump that makes washings 10 drop to swing roller 11 inner faces cleans, so clean the water yield seldom just enough.Compare with the upright type washing machine that washer box is vertically placed, the cleaning water yield of use 1/2 is just enough.Usually, in tumbling-box washing machine, water level L1 specific rotation tumbler tube 11 inner bottom surfaces of rinse water are higher.

In this matting, make 16 runnings of washings circulating pump and make the rinse water circulation.This rinse water becomes recirculated water by carrying out following circulation, near the locational water discharge outlet 12b in the minimum position of its part rear side end face of the dress water tank 12 of being located at inclination flows out and is inhaled into the washings circulating pump 16, discharge and flow in the end of a thread capture mechanism 5 from water inlet 5e from washings circulating pump 16 by circulation pipe 17, capture the end of a thread catcher/filter 5d in the mechanism 5 and after capturing the end of a thread, flow out to circulation water injection pipe 18 by the end of a thread, be injected in the swing roller 11 (dress water tank 12) from the water filling oral area 18a of circulation water injection pipe 18 front ends from delivery port 5g.

The water level L1 of this rinse water is that bottom surface is higher in the specific rotation tumbler tube 11.Because swing roller 11 and dress water tank 12 are all obliquely and are provided with, so from the depth of water of the water level L1 of rinse water front part shallow (H2), at rear end dark (H1) at dress water tank 12.That is be the deep water position, in the part that water discharge outlet 12b is set.

In the cleaning, decomposite the end of a thread (flannelette) from washings 10.The end of a thread that decomposites flows out in the rinse water and at this cleaning water float.Though under the many states of the water yield of rinse water the end of a thread from washings 10 flow out to the rinse water preferably and more the end of a thread floating, tumbling-box washing machine is because rinse water is few, so exist the end of a thread to be difficult to flow out to tendency in the rinse water.

But in the dark zone of rinse water as the rear side end part of dress water tank 12, because the water yield of washing by soaking thing 10 is many, so compare with the more shallow anterior end branch of the depth of water, the end of a thread flows out well and more the end of a thread will clean water float.Water discharge outlet 12b captures mechanism 5 so washings circulating pump 16 can suck the rinse water that contains more the end of a thread and can send into the end of a thread, so improve the end of a thread arresting efficiency owing to be located on the position of rear side end part of the dress water tank 12 that this type of the end of a thread flows out morely.In addition, because water discharge outlet 12b at the darker part opening of the depth of water of rinse water, so washings circulating pump 16 does not suck air, and does not damage the function of pump.

The end of a thread captures mechanism 5 and captures the end of a thread by outside water inlet 5e the flow into recirculated water in the box 5b (rinse water) is flow in the end of a thread catcher/filter 5d from the 5k of inlet opening portion of filter box 5c.If the end of a thread catcher/filter 5d since recirculated water from the 5k of inlet opening portion of filter box 5c flow into then in this filter box 5c the mode with Dutch roll stretch, so the end of a thread that captures is sequentially piled up from the inside to surface and can be accumulated more the end of a thread.

The recirculated water of removing the end of a thread by the end of a thread catcher/ filter 5d box 5b and flowing into the recess 5f that catchments outside the outflow opening 5h of filter box 5c flows out to, and flow out to circulation water injection pipe 18 from delivery port 5g.The recirculated water that flows out to circulation water injection pipe 18 flows down and is discharged in the swing roller 11 and is sprayed on the washings 10 from water filling oral area 18a along this circulation water injection pipe 18.

Because the front opening of water filling oral area 18a is towards the inner bottom surface of swing roller 11, so the washings 10 of recirculated water in swing roller 11 of discharging from this water filling oral area 18a sprays, so rinse water (recirculated water) can immerse washings 10 well, therefore, just can finish the good washing of efficient with the less cleaning water yield.In addition, because recirculated water directly is sprayed onto on the washings 10, flows out in the recirculated water well and remove so can make attached to the end of a thread efficient on the washings 10.

In this type of matting, though the rinse water that stores in the dress water tank 12 stirs and produces fluctuation by the rotation of swing roller 11, but swing roller 11 and dress water tank 12 are owing to its front (clothing gateway 11a, 12a side) tilts to updip ground, so the height H 3 from the water level L1 of rinse water to the minimum position at clothing gateway 11a, 12a edge is bigger than horizontal, so can prevent simply that sealing spills from clothing gateway 12a.This in rinsing process described later too.

If matting finishes, then stop the running of washings circulating pump 16, open drain solenoid valve 23 and make the rinse water in the dress water tank 12 flow out to externally drained pipe 24.And, the rotating speed of drum drive motor 13 is brought up to contained rinse water in dehydrating speed and the centrifugal washings of sloughing in the swing roller 11 10.

If the centrifugal dehydration of rinse water finishes, then the rotating speed with drum drive motor 13 is reduced to predetermined rinsing rotating speed, close drain solenoid valve 23, supply with washings up to predetermined rinsing water level L1 with reference to opening water supply electromagnetic valve 20, and washings circulating pump 16 is turned round and finish the rinsing process first time of circulation washings from the water level detecting signal of water level sensor 26 output.

At this for the first time in the rinsing process, same with above-mentioned matting, repetition is mentioned washings 10 by the rotation of swing roller 11 and is made its motion that drops to bottom surface, and together sucks and circulate to carry out with the end of a thread with washings circulating pump 16 and capture the rinsing that mechanism 5 captures by flowing out to the end of a thread in the washings and this washings.

If rinsing process finishes for the first time, then stop the running of washings circulating pump 16, and open drain solenoid valve 23 and the washings in the dress water tank 12 are flowed out in the externally drained pipe 24.And, the rotating speed of drum drive motor 13 is brought up to dehydrating speed with contained washings in the centrifugal washings of sloughing in the swing roller 11 10.

If the centrifugal dehydration of rinse water finishes, then the rotating speed with drum drive motor 13 is reduced to predetermined rinsing rotating speed, close drain solenoid valve 23, with reference to opening water supply electromagnetic valve 20 and supply with washings up to predetermined rinsing water level L1 from the water level detecting signal of water level sensor 26 outputs, make 16 runnings of washings circulating pump, carry out the rinsing process second time of circulation washings.

At this for the second time in the rinsing process, with above-mentioned first time rinsing process same, repetition is mentioned washings 10 by the rotation of swing roller 11 and is made its motion that drops to bottom surface, and together sucks with washings circulating pump 16 and circulate and capture mechanism 5 with the end of a thread and capture by flowing out to the end of a thread in the washings and this washings.

If rinsing process finishes for the second time, then stop the running of washings circulating pump 16, and open drain solenoid valve 23 and the washings in the dress water tank 12 are flowed out in the externally drained pipe 24.And, the rotating speed of drum drive motor 13 is brought up to dehydrating speed with contained washings in the centrifugal washings of sloughing in the swing roller 11 10.If final dewatering finishes, then stop the running of drum drive motor 13 and finish washing and whole operations of dehydration.

The cleaning that the end of a thread captures mechanism 5 is undertaken by catching handle 5m and filter box 5c being taken off from outer box 5b.If the catcher/filter 5d in the filter box 5c that will take off from outer box 5b is pulled out to outside this filter box 5c by the 5k of inlet opening portion, then because catcher/filter 5d becomes inside-out, so can be easy to remove the end of a thread that is captured in this catcher/filter 5d.

Because the end of a thread captures mechanism 5 and is located at dress water tank 12 tops, if so stop the running of washings circulating pump 16, then the interior recirculated water of filter box 5c and outer box 5b flows into the recess 5f and discharge apace from this filter box 5c by delivery port 5g and circulation water injection pipe 18 of catchmenting of this outer box 5b.Therefore, stop to wash and the running of dehydration procedure after, the end of a thread captures not residual recirculated water in the outer box 5b of mechanism 5, so also can not flow out even take off filter box 5c water.In addition, if owing to stop washings circulating pump 16, recirculated water in the then outer box 5b is got rid of rapidly, so even also can carry out the cleaning that the end of a thread captures mechanism 5 midway simply at washing procedure, also can supspend the washing running and clear away so that the end of a thread is captured mechanism 5.

And, by adopting default filter box loading and unloading sensor, can prevent under the state that takes off filter box 5c, to carry out washing procedure and washings and overflow from the end of a thread capture mechanism 5 to detect whether the end of a thread catcher structure 5 took off, can not carry out washing procedure under the state that takes off filter box 5c structure.

Come the end of a thread captured with reference to Fig. 7 (a) and (b) and be described in more detail.

Shown in Fig. 7 (a), can increase the washing water yield that stores in the dress water tank 12 by the tilt angle theta that increases swing roller 11 and dress water tank 12, enter in the swing roller 11 and the immersion water yield of washing by soaking thing 10 thereby can increase.And, even certain washing water yield also can increase the immersion water yield of washing by soaking thing 10 by the tilt angle theta that increases swing roller 11 and dress water tank 12.This is because can make the clothing gateway 12a of dress water tank 12 uprise (H2) and be difficult to spilling water by the tilt angle theta that increases swing roller 11 and dress water tank 12, by increasing tilt angle theta, can make washings since when focusing on the depth of water (H1) of the rear end side part of dress water tank 12 and deepen washings 10 also concentrate on the rear end part of swing roller 11.

Its result shown in Fig. 7 (b), can improve the capture rate of the end of a thread by the tilt angle theta that increases swing roller 11 and dress water tank 12.

In the washing water yield is 30L (liters), and tilt angle theta is under 30 ° the situation, and the washing water yield of washings 10 that immersion concentrates on the rear end side (inboard) of swing roller 11 is about 18-20L.By inclination swing roller 11 like this, dress water tank 12, owing to increased the washing water yield of washing by soaking thing 10, the end of a thread that is positioned on the washings 10 flows out in the washings well, so improved the end of a thread capture rate.Tilt angle theta is that the end of a thread capture rate is about 15% under the situation of 0 ° (level), and relatively, tilt angle theta is that the end of a thread capture rate is brought up to and is about 75% under 30 ° the situation, and the end of a thread capture rate has improved 5 times.

And scourability (washing force) is that the effect that the bump of feature of the tumbling-box washing machine of level (tilt angle theta=0 °) cleans improves by the rotation direction as swing roller 11, and along with tilt angle theta increases and descends.If tilt angle theta surpasses 20 °, then scourability descends and becomes significantly, and drops to 65% of tilt angle theta=0 ° during in tilt angle theta=30 °.

Therefore, in the tumbling-box washing machine of the specification of paying attention to the end of a thread capture performance, the tilt angle theta that makes swing roller 11 and dress water tank 12 is near the wide-angle below 30 ° θ=30 °, in the tumbling-box washing machine of the specification of paying attention to washing force (scourability), the tilt angle theta that makes swing roller 11 and dress water tank 12 is near the low-angle below 20 ° θ=20 °.And in the tumbling-box washing machine of the specification of paying attention to the end of a thread capture performance and washing force on an equal basis, it is desirable to make the tilt angle theta of swing roller 11 and dress water tank 12 is 25 °.

In dehydration, produced powerful vibration force by the uncompensated load that is produced of concentrating of the washings 10 in the swing roller 11.Though this vibration force is delivered to dress water tank 12,,, diminish so be delivered to the vibration of housing 1 so alleviate by this vibrationproof supporting mechanism because dress water tank 12 is supported by vibrationproof supporting mechanism (pendulum spring 14a, 14b and buffer 15).

Owing between swing roller 11 and dress water tank 12, be provided with clearance G, and the water discharge outlet 12b of dress water tank 12 is positioned near the minimum position partly of rear side end face of the dress water tank 12 of inclination, so opening drain solenoid valve 23 and from drainpipe 22 during to outside drainpipe 24 drainings, washings in the dress water tank 12 are because smooth mobile in the slanted gap of clearance G, so the draining smoothness of washings can shorten water discharge time.In addition, since smooth from the water vent unsteady flow of the centrifugal washings of deviating from of washings 10 in dehydration procedure, so can be suppressed at the foam that produces in the dehydration procedure.

Then, the water yield in the matting and the water yield in the rinsing process are described.

Removing enough cleaning water yields attached to the dirt on the washings 10 when being 30L, can not carry out abundant rinsing with the rinsing water yield of identical water yield 30L.Owing to carry out rinsing diluting the detergent ingredients that penetrates in the washings 10 with washings, dilute fully also with the rinsing water yield of 30L that rinsing is difficult so will be adsorbed in detergent ingredients (interfacial agent) on the washings 10.

Here, rinsing process carries out so it is desirable to use than the more water yield of matting because dilution also drifts out the detergent ingredients that is attached on the washings 10 well.If increase the rinsing water yield, then, carry out the end of a thread well and remove so can capture mechanism 5 by the end of a thread because the end of a thread that is attached on the washings 1 flows out well.

If making the rinsing water yield with respect to the cleaning water yield of 30L is 37L, then owing to can carry out the dilution of detergent ingredients well, thus can reduce the number of times of rinsing process, thus whole wash time can be shortened.

Like this, if improve rinse efficiency, then can reduce the corner of swing roller 11 by increasing the rinsing water yield.That is,, can make the rotating ratio washing procedure of swing roller 11 low by increasing the rinsing water yield.Particularly, if the rotating speed of the swing roller in the washing procedure 11 is 50rpm, then the rotating speed with the swing roller in the rinsing process 11 is reduced to 20-30rpm, and, can on the rotating direction, reverse with interior corner with each 180 °.

The dc brushless motor of the current transformer type of drive of using as drum drive motor 13 is owing to be if reduce rotating speed then torque increases, so also can eliminate the torque deficiency by reducing rotating speed even increase the rinsing water yield in rinsing process on its characteristic.And, be low speed and to make reverse angle be below 180 ° by the rotating speed that makes swing roller 11, can reduce the load torque of drum drive motor 13.

Therefore, even increasing the caused load torque amount of the rinsing water yield increases, by reducing the rotating speed and the reverse angle of swing roller 11, can avoid increase, and the maximization and the cost that can suppress drum drive motor 13 rise as the load torque of the direct current generator of the current transformer type of drive of drum drive motor 13.That is, the direct current generator of current transformer type of drive is compared with single phase induction motor, even owing to output torque under low speed rotation is also big, so can make heavy swing roller 11 with low speed rotation in the rinsing process that increases the rinsing water yield.

Have, the rotating speed of swing roller 11 it is desirable to be 40-50rpm in matting, is 20-30rpm in rinsing process again.

Come the relation of the rotary load torque of the amount of washings 10 and swing roller 11 is described below with reference to Fig. 8, Fig. 9.

As shown in Figure 8, tumbling-box washing machine has swing roller 11 and dress water tank 12, and the direction of the pivot axis of this swing roller 11 is the type of level and the type of direction for tilting of pivot axis.The tumbling-box washing machine of inclination type is set at 15 °-30 ° with the tilt angle theta of the pivot axis of swing roller 11.

Fig. 9 is that the rotating driveshaft 13a of expression rotation driving swing roller 11 goes up the curve map that concerns between the amount (load) of added rotary load torque and washings.Have, the rated load amount of swing roller 11 (amount of washings) is 8kg again.

When load was the pact half (4-5kg) of rated load amount, the rotary load torque was maximum, and if load for more than it then the rotary load torque reduce.The washings of packing in swing roller 11 is under the situation of rated load amount (8kg), because packing into equably and setover substantially in swing roller 11, washings tails off, so when swing roller 11 rotations, be used for diminishing from the required power that this swing roller 11 lower curtates are mentioned, the rotary load torque of swing roller 11 diminishes, so be under the situation of pact half (about 4kg) of rated load amount (8kg) at washings, because washings concentrates on swing roller 11 lower curtates, so need be used for this washings being mentioned the bigger power of the topmost position to this swing roller 11 by hoisting mechanism 11c, big thereby the rotary load torque becomes.

And if comparison level formula and tilting, then tilting is littler than the torque of horizontal rotary load.If the reason that the rotary load torque of tilting diminishes is because swing roller 11 tilts then washings concentrates on the rear side end face of these swing roller 11 inboards, so the amount of the washings of being mentioned by hoisting mechanism 11c reduces and reduces and mention power.Therefore, make the tumbling-box washing machine of the tilting that swing roller 11 tilts have the rotary load torque that can reduce swing roller 11 and can reduce to rotate the advantage of the output torque of the drum drive motor 13 that drives this swing roller 11.

Then, further specify rinsing with reference to Figure 10, Figure 11.

Figure 10 is the figure of the water level of expression in the washing procedure, and L4 (depth of water H4) is the water level in the matting, and is to be used to wash 8kg washings 10 and water level when supplying with the rinse water of the 30L water yield.Because utilize to possess the washing machine that has a vertical washer box of stirring vane in washer box central authorities and wash the employed cleaning water yield of 8kg washings and be generally 60L, so tumbling-box washing machine can be realized water saving.

L5 (depth of water H5) is the water level in the rinsing process, is the water level when supplying with the washings of the 37L water yield.As mentioned above, owing to rinsing is undertaken by the dilution detergent ingredients, so the rinsing water yield is more favourable.Rinsing process is undertaken finishing rinsing twice by the rinsing water yield of returning with 37L/.Because the rinsing water yield of returning with 60L/ in the washing machine of common vertical washer box is carried out twice rinsing, so rinsing degree by comparison is slightly poor.

As its countermeasure, the dehydrating speed of the swing roller 11 in centrifugal the sloughing of the washings when advancing to rinsing process for the second time after the rinse water when advancing to rinsing process by improving after finishing matting centrifugal sloughs and rinsing process finishes for the first time improves dehydration rate, and adopt and to open water supply electromagnetic valve 20 and limit and spray the method that the spray dehydration etc. of centrifugal dehydration is carried out in waterside from the beginning, can realize and the equal rinsing of washing machine that possesses vertical washer box to washings 10.Like this, can eliminate because of the not enough peculiar smell that washing agent produced that residues in the washings 10 of rinsing.

And, if increase the rinsing water yield, the end of a thread that is attached on the washings 10 is flowed out in the washings well, capture mechanism 5 by the end of a thread and capture the end of a thread well, thereby can carry out the rinsing that the end of a thread is removed function admirable.

Figure 11 is the curve map of the relation of expression corner of swing roller 11 and rotary load torque.At water level is in the matting of L4, and the rotary load torque is for maximum when the corner of swing roller 11 is 135 °.In the rinsing process of water level L5, the rotary load torque is for maximum when the corner of swing roller 11 is 90 °.

If increase the rinsing water yield, then need to increase the output torque that rotation drives the drum drive motor 13 of swing roller 11.But, if use current transformer drive-type direct current generator to be used as drum drive motor 13, then, can increase the output torque by in rinsing process, coming low speed rotation to drive swing roller 11 with the rotating speed (20-30rpm) lower than matting medium speed (40-50rpm) according to its characteristic.Like this, in the rinsing process of high water level H5, drive swing roller 11 by rotating with the speed lower than matting, and by the drum drive motor (current transformer drive-type direct current generator) 13 of output characteristics necessary in the matting, the rinsing that can realize ideal.

And, the rotation of swing roller 11 drives that the water yield is under the situation of 30L in matting, being the turn-on time to drum drive motor 13 energisings that 8 seconds-18 seconds, dwell time (power-off time) are to connect in cycle of 4 seconds-6 seconds and the positive and negative rotation of cutting off the power supply drives.Have, turn-on time, (8 seconds-18 seconds) became according to cloth amount and cloth matter again.

But, in rinsing process, if to capture performance be the rotation driving time (turn-on time) that prolongs swing roller 11 under the state of 50L making the water yield in order to improve rinsing performance and the end of a thread, then produce the problem that washings begin that wave is arranged, dress water tank 12 rocks and clash into housing 1 significantly in swing roller 11 and the dress water tank 12.

Here, in rinsing process, the rinsing water yield is being set at 37L, when the speed setting of swing roller 11 is 30rpm, by making the turn-on time to drum drive motor 13 energisings is 0.5 second-0.9 second, and the corner that can make swing roller 11 is 90 °-162 °, and rotates in 135 ° scope.Thereafter, making power-off time is 1 second-2 seconds, rotates up the negative side and drives 0.5 second-0.9 second.Drive by rotation like this, can suppress to adorn shaking also of water tank 12 and can carry out quiet rinsing.

In addition, at the rotating speed that makes swing roller 11 is under the situation of 20rpm, if owing to make the turn-on time to drum drive motor 13 energising is 0.5 second-0.9 second, then the corner of swing roller 11 be 60 °-108 ° so not enough, be 0.7 second-1.4 seconds so it is desirable to make turn-on time.

Have again, in the running that can suppress this rinsing process that shakes, though shortened to 0.5 second turn-on time-0.9 second (90 °-135 °), but owing to supply with the water yield washings of Duoing than the cleaning water yield in the matting, so can dilute detergent ingredients contained in the washings 10 well, so shortened the rotation driving time of swing roller 11 and enough.
