Technical field
The present invention relates to a kind of automatic washing machine, more particularly, the present invention relates to a kind of drainage arrangement and controlling arrangement in washing of automatic washing machine, be provided with a secondary connector in the described drainage arrangement, so as by the mode of setting in wash cycle and take off/impeller and washing/dehydrating bucket are rotated individually or simultaneously in the draining circulation.
Background technology
Washing machine can be washed till former state with various dirty linens according to certain setting means and not damage the quality of these clothings.Owing to developed various textiless in the last few years, therefore needed the higher washing machine of a kind of washing force.
What Fig. 1 showed is a kind of typical common full-automatic single barrel washing machine sectional drawing of (as disclosed the sort of among the open H7-227494 of Japan Patent).
Common full-automatic single barrel washing machine comprises the outer bucket 2 that is positioned at laundry fuselage 1, the washing/dehydrating bucket 3 that is positioned at outer bucket 2.Impeller (pulsator) 4 (being a kind of agitator) is installed in the inside of washing/dehydrating bucket 3, and washing motor 5 is installed under the outer bucket 2.Connector 9 and reduction gearing 8 are installed on the motor 5, and wash shaft 6 and dehydrating shaft 7 directly are connected between reduction gearing 8 and the impeller 4.Draining valve 12 and scupper hose 13 are installed in the zone of outer bucket below 2, after washing and rinse cycle waste water are discharged to outside the washing machine.Bung 10 is installed in the upper top of outer bucket 2.The fluid balance device 11 at washing/dehydrating bucket 3 tops prevents to produce vibration and noise in washing and dehydration.
In order to improve washing force by impeller 4 in the conventional laundry apparatus with above-mentioned system and washing/dehydrating bucket 3 are rotated simultaneously, be provided with independent impeller drive motor and washing/dehydrating bucket CD-ROM drive motor, or at this two one of on reduction gearing 8 is set.Yet this washing machine makes that the people recognizes is impeller 4 and washing/dehydrating bucket 3 washing machine and the control method thereof with opposite direction rotation.In addition, although the torque forward of washing motor 5 can be passed to washtub 6 and dehydration barrel 7 by the structure of forming by reduction gearing 8, connector 9 and washing motor, but there is not the accurate control of motor 5, just can not give axle with the torque accurate transfer of motor 5, the washing machine of this so far energy accurate transfer moment does not drop in the practical application as yet.
Fig. 2 is the sectional drawing of the common automatic washing machine (open H8-57186 is disclosed the sort of as Japan Patent) of another kind of type.
The system of this conventional laundry apparatus is with shown in Figure 1 identical, the lower end structure of different is outer bucket 2 and washing/dehydrating bucket 3 and according to the clothing kind or fix or rotate the combination of the pattern of washing/dehydrating bucket 3 in the unlatching situation of washing or rinse cycle middle cover (not shown).Specifically, with regard to its system, last wash shaft 6a is connected with following wash shaft 6b by solar reduction gear 8, and washing motor 5 is connected down on the wash shaft 6b.Following dehydrating shaft 6c is connected with last dehydrating shaft 6d by brake drum 20.Following wash shaft 6b is connected with belt pulley 14a on washing motor 5 by belt pulley 14b and belt 15.
In having the common automatic washing machine of said system, if the user has set the washing mode that washs large-scale clothing, then thereby driver running preset time is with the 27 pull-up certain distances of the pull bar shown in Fig. 3 A, this distance makes brake drum 20 and brake band leave certain distance, so that the 3 independent rotations of washing/dehydrating bucket, and make impeller 4 and washing/dehydrating bucket 3 with opposite direction rotation.In this case, engaging gear and aforementioned attachment keep engagement.If the user has set the washing mode that washs meticulous clothing, thereby then driver disconnects and to make brake bar 27 return to reset condition, and brake drum is connected with the brake band (not shown), with fixing washing/dehydrating bucket 3.In this case, if user's uncap when washing/dehydrating bucket 3 is unfettered, only in view of stability reasons, washing/dehydrating bucket 3 is converted to fixing pattern at once.
Fig. 3 A has illustrated the joint running of the open disclosed washing machine shown in Figure 2 of H8-57187 of Japan Patent during its wash cycle.
If connect brake bar 27 has been moved by " L " to L1 because of driver " a segment distance; although two attachment 23 of cantilever 22 front ends still with engaging gear 21 engagements; because brake band (not shown) and brake drum 20 have left certain distance, make dehydrating shaft become unfettered.That is, when attachment 23 meshed with engaging gear 21, the brake drum that joint reed (not shown) will not inserted down wash shaft fused (can't be connected) with following dehydrating shaft, and impeller and washing/dehydrating bucket are with opposite direction rotation.Washing/dehydrating bucket 3 is in unfettered pattern at this moment.On the other hand, if driver disconnects, then brake bar 27 returns to i.e. " L " position of reset condition by reed 26, thereby is connected with brake drum by brake band.Washing/dehydrating bucket 3 is in fixed mode at this moment.
Fig. 3 B has illustrated the joint running of washing machine shown in Figure 2 during dewatering cycle, and wherein, if brake drum 20 is thrown off fully, washing/dehydrating bucket 3 can rotate at a high speed.
If pull bar 27 has moved a segment distance by " L " to " L2 " by driver, then two attachment 23 of cantilever 22 front ends are deviate from from engaging gear 21.This makes the brake drum of wash shaft under the insertion be abutted against the restoring force that closes the reed (not shown) with following dehydrating shaft and fuses, thereby impeller and washing/dehydrating bucket are rotated in the same way.That is, because therefore the torque of washing motor can carry out dewatering cycle not by reduction gearing but be directly passed to impeller and washing/dehydrating bucket.
As shown in Figure 1, although conventional laundry apparatus can by during washing and dewatering cycle simultaneously rotary blade 4 and washing/dehydrating bucket 3 improve washing force, during uncap washtub stop suddenly can making the user think that washing machine is undesired by mistake.
And, when impeller during the wash cycle transships, although not rotating in the same way that dehydrating shaft and wash shaft produce by planetary gear (a kind of reducing gear) makes impeller avoid overload, but need carry out repeatedly therefore needing long wash time and having reduced washing force until getting rid of overload owing to get rid of the operation of overload.
Although figure is not gone through, among the figure for during washing, rinsing and dewatering cycle, should become prerequisite that impeller and washtub rotate simultaneously engage and discharge structure is not made an explanation fully.And the geared motor of draining not being used is fully made an explanation.

The specific embodiment
Explain the preferred embodiments of the invention now, accompanying drawing has showed these embodiments
Embodiment.
What Fig. 4 showed is the sectional drawing of the automatic washing machine of the preferred embodiment of the invention.
The automatic washing machine of the preferred embodiment of the invention comprises: the wash shaft 46 that be arranged in washing/dehydrating bucket 43, links to each other with impeller 44, the dehydrating shaft 47 that be arranged in outer bucket 42, links to each other with washing/dehydrating bucket 43, wash shaft 46 are installed on same the straight line and by engaging mechanism 49 with dehydrating shaft 47 and link together.Belt 55 will be connected the first belt pulley 54b on the engaging mechanism 49 and be connected the second belt pulley 54a that washs on the motor 45 and couple together.Drainage system is installed under the outer bucket 42, comprises one-level or two-stage drainage system, and drainage system has connection flexible pipe 65, draining valve 64, scupper hose 66 and the connecting pin 63 that is connected outer bucket 42 bottoms.This drainage system links to each other with the geared motor with dual output cam mechanism by connecting rod 62; and this geared motor 61 is with normal or mutually opposite direction rotary blade 44 and washing/dehydrating bucket 43, operates corresponding fixed mode, rotary mode, rotation/fixed mode or high speed rotary mode with one-level or the secondary that adapts to geared motor 61.
At first, the automatic washing machine with said system under the control of microcomputer 11 (seeing Figure 12), in fixing or rotary mode respectively with normal or opposite direction rotary blade 44 and washing/dehydrating bucket 43, thereby carry out common washing or rinse cycle.
The second, if washing machine cover 50 is opened in rotation/fixed mode, then washing/dehydrating bucket 43 still rotated preset time before stopping, and in the meantime, impeller 44 only is to rotate in order to improve washing force.
The 3rd, in the high speed rotary mode, thereby, impeller 44 and washing/dehydrating bucket 43 carry out dewatering cycle by being rotated at a high speed.
Fig. 5 is a width of cloth perspective diagram, has showed being connected of engaging mechanism and drainage arrangement among Fig. 4, and Fig. 6 is the sectional drawing of drainage arrangement shown in Figure 5, and Fig. 7 is the perspective view of the critical component of jockey in the engaging mechanism shown in Figure 5.
With reference to Fig. 5, in joint and drainage system that washing machine shown in Figure 4 adopts, engaging mechanism 49 comprises that one movably is fixed on engaging lever 69 on engaging mechanism 49 housings by bolt 74, and one movably is fixed on the brake lever 70 that fixed frame 73a goes up and contacts with gap adjustment screws 72.Comprise attaching parts 63 that have adjustable projection 67 with the drainage system of engaging mechanism interlocking, the fixed part 63a that drainage system is used, the hook shaped component 68 used with the connecting rod 62 of geared motor 61, be connected the draining valve 64 on the fixed part 63a, and geared motor 61, this motor has a hook-type projection 75 that inserts hook shaped component 68, in order to the adjustable projection 67 on the attaching parts 63 is changed to first or the second level.
With regard to above system,, be fixed on the end that adjustable projection 67 on the attaching parts 63 promotes brake levers 70 when driven wheel drive motor 61 during with connecting rod 62 pull-ups.Because the mobile projection 72a that has promoted on the gap adjustment bolt 72 of brake lever 70, the attachment 71 on the engaging lever 69 get loose.In this case, if attachment 71 and the engagement of engaging gear (not shown), as conventional laundry apparatus, because engage the reed (not shown) brake drum of wash shaft under the insertion and following dehydrating shaft are fused, so washing/dehydrating bucket 43 is mutual to opposite direction rotation with impeller 44.On the other hand, if attachment 71 do not mesh with the engaging gear (not shown), still as conventional laundry apparatus, because engage reed the brake drum of wash shaft under the insertion and following dehydrating shaft are fused, so washing/dehydrating bucket 43 rotates at a high speed with identical direction with impeller 44.In this case, because the torque of washing motor is by reduction gearing but directly make the rotation of impeller and washing/dehydrating bucket, what therefore carry out is dewatering cycle.When the connecting rod on the geared motor 61 62 during with the complete pull-up of attaching parts 63, the draining valve 64 that is connected on the fixed part 63a is opened, and therefore can carry out dewatering cycle.Like this because brake lever 70 and engaging lever 69 interlockings and combine with the brake drum (not shown) by the brake band (not shown) or throw off, so brake lever 70 can make automatic washing machine fix or rotary mode in operate.
The drainage system of automatic washing machine of the present invention is elaborated with reference to Fig. 6 and Fig. 7.
Automatic washing machine of the present invention comprises attaching parts 63, these attaching parts are installed in the drainage system, during getting rid of waste water, operate, these attaching parts have a hook shaped component 68 that is used to hook the connecting rod 62 that is positioned on the geared motor 61, a long guiding hole 84 that is used for fixing adjustable projection 67, with one be used for hooking and the fixing fixed part 63a of the draining valve 64 of drainage system, this washing machine also comprises a geared motor 61, it hooks and is fixed on the hook shaped component 68 of attaching parts 63 1 sides by the hook-type projection 75 of connecting rod 62 1 ends, in order to an end of the device pull-up brake lever 70 by adjustable projection 67.
This drainage arrangement comprises a bellows 76, this bellows is compressed from the horizontal pull of geared motor 61 and the elastic force of one group of reed, thereby open draining valve 64, be used to guide first bar 77 and second bar 78 of bellows 76 and first and second reeds 79 and 80, and one along with the guiding of first bar 77 and second bar 78 mobile draining valve 64, thereby open or close the connection flexible pipe 65 that links to each other with washing/dehydrating bucket 43 and the path between the scupper hose 66.Adjustable projection 67 inserts in the long guiding hole 84, and this projection has a gap to the engaging mechanism of considering the joint clearance, and this projection is also fixing with bolt 67b and nut 60.The top of adjustable projection 67 has groove 67a in order to regulate this gap.First bar 77 has insertion first reed 79 and step 81 wherein, and an end hook of reed 79 is gone in the groove of draining valve 64, and the other end hooks hole 63b, and the rib 82 on the step 81 and second bar 78 is installed on the same straight line.Second bar 78 has second reed 80 and bellows 76, and they are installed on the periphery of second bar 78.
In above-mentioned drainage arrangement, adjustable projection 67 opens or closes draining valve 64 according to the operating mode of moving corresponding to the stretching of connecting rod 62, below will be elaborated to this.
During with connecting rod 62 pullings one segment distance D,, in the draining circulation,, will be arranged in first reed, 79 pullings of first bar 77 of drainage arrangement by to geared motor 61 power supplies that are installed on the automatic washing machine lower frame 73 as first order pulling.In this case, although first bar 77 has moved a segment distance D under the effect of the elastic force of first reed 79, second bar 78 does not move.When connecting rod 62 had moved distance D, adjustable projection 67 promoted brake lever 70, and this is adjustable, and projection 67 passes in a pair of pad 83 insertion long guiding holes 84, and for brake lever 70, this is adjustable, and projection 67 is fixed on the position of 69a by nut 60.Pull distance is lower than apart from E, and E is formed in the step 81 and the distance that is formed between the rib 82 all in second bar 78 in first bar, the 77 1 ends outsides.When geared motor continued from first order pulling position pulling connecting rod 62, connecting rod 62, brake lever 70 and adjustable projection 67 were pulled, and along with the promotion of the rib 82 of the 81 pairs second bar 78 1 end inboards of step of first bar, 77 peripheries, had compressed second reed 80.Because second reed 80 is compressed, bellows 76 is compressed to open draining valve 64, so the slurry in the washing/dehydrating bucket 43 can be discharged outside the bucket.When geared motor 61 turn-offed, by the restoring force of second reed 80 and brake lever 70, connecting rod 62, brake lever 70, adjustable projection 67, second bar 78 and first reed 79 were returned to the home position successively with the bellows 76 and first bar 77.When bellows 76 and draining valve 64 were closed the space that connects between flexible pipe 65 and the scupper hose 66, draining stopped.Therefore, because this drainage arrangement has an effectively also simple system in washing/dehydrating bucket 43, this system is not the slurry of discharging in the first order pulling position of geared motor 61 but in its pulling position, second level in the washing/dehydrating bucket 43, so this drainage arrangement can use common attaching parts.Because partial joint running is same as the prior art, has therefore omitted detailed explanation.
What Fig. 8 A showed is the sectional plan view of the critical component of geared motor 61 shown in Figure 5, and Fig. 8 B is the sectional drawing of output cam shown in Fig. 8 A.
With reference to Fig. 8 A, geared motor 61 comprises internal gear parts that are used to reduce motor speed, and output cam 91, its is according to making connecting rod 62 move to the running of the motor at one-level 62-1 or secondary 62-2 place, makes power connection or shutoff by contact 92 and terminal 93-1,93-2 and 93-3.Shown in Fig. 8 B, make the output cam 91 of contacting or shutoff comprise last output cam 91-1 with different radii, the both sides radiuses is different and less than the following output cam 91-2 of last output cam 91-1 radius, lay respectively at output projection 91-1 and near the first contact 92a and the second contact 92b of following output cam 91-2, and common 93-2, thereby this output cam 91 is according to the first order or the second level running of the interlocking running control gear drive motor 61 of output cam 91-1 on it and following output cam 91-2.
Fig. 9 A～9C performance be the relation between the contact between output cam and the switch in the geared motor shown in Fig. 8 A, Figure 10 A～10C has showed the drive circuit of geared motor shown in Fig. 8 A, what Figure 11 showed is when being applied to electric energy on the geared motor shown in Fig. 8 A, the arrangement of time of triac and switch.
With reference to Figure 10 A, pull down terminal 93-2 and 93-3 after, the staff may often connect it with reporting to the leadship after accomplishing a task.Under this condition, if first triac TR1 that makes geared motor carry out the one-level operation connects, then electric current flows to the other end by first triac TR1 → first switch SW, 1 → second switch SW2 by an end.If second switch SW2 connects, then short circuit disconnects the triac TR1 in the controller.Therefore, cut-off out state, be provided with cam groove 91-3 among the output cam 91-2 down in order to make second switch SW2 place.
What Fig. 9 A and 10A showed is the state of not powering to geared motor 61, it is first and second triac TR1 and the TR2 reset condition when disconnecting, wherein, first switch SW 1 that is connected on first triac TR1 is in on-state, is connected second second switch SW2 on the triac TR2 and is in off-state (seeing the arrangement of time of Figure 11).
What Fig. 9 B and 10B showed is that geared motor 61 has been finished the state the when first order operates.That is, under state shown in Fig. 9 B and the 10B, if only there is first triac TR1 to connect, then electric energy is supplied with relay R Y automatically, because electric energy passes through first switch SW, 1 supply gear drive motor 61, thereby has spurred connecting rod 62, and output cam 91 is rotated counterclockwise.When output cam 91 rotates to a certain degree (in general, when through t1 after a while, first switch SW 1 disconnects), the second switch SW2 of following output cam 91-2 connects.That is, although thereby the disconnection of first switch SW 1 cut off the electric energy of geared motor 61 output cam 91 and connecting rod 62 stopped, first triac TR1 still keeps connecting (seeing the arrangement of time among Figure 11).
What Fig. 9 C and 10C showed is that geared motor 61 has been finished the state the when second level operates.Promptly, under the state shown in Fig. 9 B and the 10B, if second triac TR2 connects, thereby then because electric energy makes it rotation by second switch SW2 supply gear drive motor 61, thereby make output cam 91 rotations and connecting rod 62 is pulled to gear-box.In this case, more stable in order to make running with reference to Figure 11 although first order running is finished substantially behind t1 after a while, second level running is designed to begin to come into operation after the time through t1+ α from first order running.(in general, second switch SW2 disconnects when through t2 after a while) because second switch SW2 also disconnects, cut off the electric energy of geared motor 61 when output cam 91 rotates to a certain degree, thereby output cam 91 and connecting rod 62 stop.Only in this case, because system controlled by computer the connection to first triac of major general TR1, so not answer of connecting rod 62, but under the condition of relay R Y running, this connecting rod is parked in second level running position 62-2.Simultaneously, with reference to Figure 10 A, even the staff is with terminal 93-2 and assembling of alternately being connected again after 93-3 pulls down, because second switch SW2 is in off-state, although geared motor 61 does not turn round.(even when first triac that is used for first order running is connection) can not be short-circuited yet.Therefore, though staff's wrong terminal because the contact point effect of circuit by the dual output cam forms an open loop, therefore can prevent to damage the element in the control assembly.
Figure 12 is the fully-automatic washing machine actuating device block diagram of the preferred embodiment of the invention.
With reference to Fig. 4 and 12, this drive unit comprises microcomputer 110, I/O in order to the various controls of control relevant controlling external equipment, keying unit 112, offer microcomputer 110 and show the operating state of washing machine in order to the pattern that the user is set, water-level detecting parts 111, in order under the control of microcomputer 110, to survey the amount of the slurry that adds washing/dehydrating bucket 43, feed water valve driver part 114, thereby in washing/dehydrating bucket 43, add an amount of slurry in order to the water level control feed water valve 59 that records according to water-level detecting parts 111, the exploring block 117 of uncapping, cover 50 opening in order to carry out the cycle period detection at washing machine, the first order and second level draining valve driver part 113 and 115, in order under the control of microcomputer 110, thereby operate by the first order or the second level of draining valve 59 in geared motor 61 power supply control drainage arrangements.
In above-mentioned drive unit, microcomputer 110 is being controlled the external device (ED) of this automatic washing machine, and keying unit 112 offers microcomputer 110 with the push button signalling that the user sets pattern.When the mensuration by keying unit 112 or laundry amounts was provided with water level, feed water valve driver part 114 was opened feed water valve 59.Then, because feed water valve 59 is opened, therefore water-level detecting parts 111 detect the water level whether slurry has arrived setting, as arriving, then draining valve 64 is pulled under the condition of the first order at first order draining valve driver part 113, washing motor 45 is driven, thereby washing/dehydrating bucket 43 and impeller 44 are all rotated.During the wash cycle of washing/dehydrating bucket 43 and impeller 44 rotations, the exploring block 117 of uncapping is surveyed and is covered 50 unlatching situation, and will record signal supply microcomputer 110.If passed through the setting wash time, thereby then second level draining valve driver part 115 opens to the second level with draining valve 64 and carries out batch (-type) dehydration and powerful dehydration.
The driving rule of drive unit describes with reference to Figure 13 and 14.
Figure 13 is the control method of washing flow chart of first embodiment of the invention, especially during washing or the rinse cycle when lid is opened the function situation of washing machine.
When automatic washing machine entered washing or rinsing pattern (S130), whether this fully-automatic washing machine testing was wash cycle or rinse cycle (S131).If to record this circulation be circulation except that washing or rinse cycle to step (S131) after testing, then finish running carrying out this circulation (S140) back.If to record this circulation be washing or rinse cycle to step (S131) after testing, then rotary blade 44 and washing/dehydrating bucket 43 is mutually with opposite direction rotation (S132).That is, if this circulation is washing or rinse cycle, impeller 44 and washing/dehydrating bucket 43 just with opposite direction rotation, if not washing or rinse cycle, are just carried out this circulation (S140).According to the detection to washing or rinse cycle, in the process of impeller 44 and the 43 mutual rotations in the opposite direction of washing/dehydrating bucket, washing machine is surveyed lid and whether is opened (S133).Be opened as operculum 50, then send unusual alarm and inform that be undesired running (S135) this moment.This alarm can be used as a kind of temporarily stopping putting into new clothing.After alarm was sent, for user's safety, impeller 44 and washing/dehydrating bucket 43 all stopped.At this moment, the user can put into new clothing (S139) again.Opposite with above situation, if lid is not opened in the detection steps of uncapping (S133), then detect and whether passed through washing or the rinsing time (S134) set.If process, the then circulation (S140) except that washing or rinse cycle is if process not then repeats above-mentioned steps (S132).
Then, stop through one section preset time, survey 50 the unlatching situation (S138) of covering once more from impeller 44 and washing/dehydrating bucket 43.Be in closed condition as operculum, thereby then by making impeller 44 and washing/dehydrating bucket 43 carry out washing or the rinse cycle of remaining time mutually with opposite direction rotation.Yet, even impeller 44 and washing/dehydrating bucket 43 all stop and all giving the alarm in step (S135) and (S136) since when lid is opened all standing of impeller 44 and washing/dehydrating bucket 43, it is undesired that the user still may misread washing machine.In other words, give the alarm when opening, if impeller and washing/dehydrating bucket all standing have many users and do not think that this is a step or a step of putting into clothing in addition for security reasons owing to lid.
In order to prevent that all standing that the user sends back impeller and washing/dehydrating bucket with alarm from thinking it is that washing machine is undesired by mistake, can make following change to wash cycle.That is,, after recording lid and opening, still can after impeller and washing/dehydrating bucket have rotated a period of time with opposite direction mutually, give the alarm again and stop impeller and washing/dehydrating bucket although do not show among the figure.Figure 14 is the control method flow chart of washer operation under the lid open mode.When having selected washing or rinse cycle, impeller 44 and washing/dehydrating bucket 43 are with opposite direction rotation (S130～S132).If lid is opened, then give the alarm, consider user's safety, impeller 44 and washing/dehydrating bucket 43 rotate at a slow speed and inform that user's washing machine is not undesired (S133, S135 and S136).In addition, the step (S135-1) of sending the laundry amounts alert signal is added on the step (S135), and will sends the step (S136-1) of surveying the laundry amounts signal once more and be added on another step (S136).Like this, because impeller 44 and washing/dehydrating bucket 43 still rotate the several seconds when lid 50 is opened, thereby the user can confirm that washing machine is normal.After this illustrated identical of step and Figure 13.
Figure 15 is the flow chart of control method of washing in the second embodiment of the invention.
When wash cycle begins, according to user's decision designated water level (S150).If designated water level does not then carry out the laundry amounts detection process and is suitable for the water level of laundry amounts with detection, and continues wash cycle (S151).If the user has set suitable water level in step (S151), then the data setting ordinary water level that is provided with according to corresponding water level and suitably water level (S152).Then, open feed water valve 59 (S153) and supply water, and close feed water valve 59 (S155) to the water level of setting (S154).The initial value (S156) of whole wash time T is set then.Thereby driven wheel drive motor 61 is pulled to first order position (S157) with draining valve, washing/dehydrating bucket 43 and impeller 44 with normally/inverse direction rotation (S158), thereby carry out wash cycle.That is, automatic washing machine of the present invention make its washing/dehydrating bucket set by step (S158) operate to rotary mode from fixed mode.In other words; in engaging mechanism; if the engaging lever 69 that is connected on the draining valve 64 is pulled a segment distance; then washing/dehydrating bucket 43 and impeller 44 are with normal or opposite spin; described distance is in draining valve not cause the position of natural drainage, and makes draining valve be in not state with brake lever 70 interlockings.That is, washing machine operates under washing or rinse cycle.
After this, uncap exploring block 117 is surveyed users and whether has been opened washing machine cover (S159) under the washing state when washing/dehydrating bucket 43 and impeller 44 rotations.If do not detect and cover 50 and be opened, then washing/dehydrating bucket 43 and impeller 44 continue the wash time that rotation is set.If detect in the step (S159) and cover 50 and be opened, then calculate initial time and with the time T that calculates and scheduled time t1 relatively (S160).As shown in figure 11, in time comparison step (S160), measured the time point that geared motor 61 should drive.This is a very important step, because this time point has determined the time point that engaging mechanism should drive.Comparison by step (S160); if the user has closed washing machine cover 50 (S161) even should be no more than the scheduled time computing time (being the time that washing machine cover 50 is opened); then be pulled to by the driving of geared motor 61 under the situation of first order position (S162) at draining valve 64, washing/dehydrating bucket 43 and impeller 44 continue with normal or opposite direction rotation (S163).In other words, when the user open washing machine cover 50, when confirming the state of washing/dehydrating bucket 43 and closing cap 50 with eye, (S161～S163) wash cycle that configures can be gone on of above-mentioned several steps.By the comparison of step (S160), if the washing machine cover that calculates is opened the time more than or equal to the scheduled time, then driven wheel drive motor 61 makes draining valve 64 recover first order position (S164) and make impeller 44 rotate (S165) separately.That is, automatic washing machine of the present invention operates with rotation/fixed mode.After the user confirms one period scheduled time in uncap during the washing and with eye to the rotation situation of washing/dehydrating bucket 43 and impeller 44, when through the wash time of setting (S166), draining valve 64 is pulled to position, the second level (S167), washing/dehydrating bucket 43 and impeller 44 rotate in the same way, to comprise the dewatering cycle (S168) of batch (-type) dehydration and powerful dehydration.That is, automatic washing machine of the present invention operates with the high speed rotary mode.Like this, rotate preset times, the circulation of independent rotary blade 44 when lid is opened then by carrying out a kind of washing/dehydrating bucket 43 and impeller 44 of making, got rid of and cause the user to think the out of repair cause of washing machine by mistake, and improved washing force.
