Thus, when detecting sensor tag 13 close to switch 14 (referring to Fig. 2), according to the size for the acceleration horizontally and vertically that acceleration transducer 12 issues, amount of unbalance (M) is calculated by amount of unbalance test section 35, which is exported to amount of unbalance judging part 37.On the other hand, non-equilibrium site test section 36 exports non-equilibrium site signal to water filling control unit 38 according to the angle for calculating uneven direction from the signal of the position of the expression sensor tag 13 inputted close to switch 14.

When having input from the signal for indicating amount of unbalance and non-equilibrium site that amount of unbalance judging part 37 and non-equilibrium site test section 36 issue, control program according to the pre-stored data determines whether to some lifting rib 6 in rotating cylinder 5 and carries out water supply and the water supply water filling control unit 38.Then, selected solenoid valve 26a, 26b, 26c are opened, the water filling for being adjusted water is started.When rotating cylinder 5 generates imbalance, calculating based on the amount of unbalance starts guiding gutter 19a, 19b, 19c from chosen nozzle nozzle 25a, 25b, 25c injection adjustment water to water receiving ring element 18, when eliminating imbalance by lifting rib 6, stop the injection of adjustment water.Do not need to make the rotation of rotating cylinder 5 to slow down as a result, it can be in the generation for continuing to prevent vibration, noise in the state of dehydration operating.

It should be noted that, as shown in the determination such as Figure 14 for the lifting rib 6 that the water filling control unit 38 carries out, when between the lifting rib 6 of position B and position C that the washings agglomerate LD for constituting unbalanced element is in rotating cylinder 5, the lifting rib of adjustment water to position A is provided.In addition, when washings agglomerate LD is located near the lifting rib 6 of position A, providing when as shown in figure 15 and adjusting water to being located at position B With the lifting rib 6 of position C.

Next, the flow chart according to shown in Figure 16 carries out as described below the control flow of the dehydration operating of washing machine 1 of the invention.Figure 16 is the flow chart for indicating the control flow of dehydration operating of washing machine 1 of the invention.

In step sl, central control 31 starts dehydration, moves to step 2 in the input signal received from dehydration button (not shown) or when receiving the signal for being intended to start dehydration in washing mode operation process.

In step s 2, central control 31 notifies the signal for being intended to start low speed rotation (N1) to rotation speed control unit 33.Rotation speed control unit 33 is based on the notice and sends control signals to motor controling part 34, and motor controling part 34 is based on the control signal and is powered, and drives Rolling motor 10.Rotating cylinder 5 (is driven in rotation for 100rpm~400rpm) in the present embodiment with scheduled revolving speed, moves to step S3 as a result,.

In step s3, central control 31 reads non-equilibrium site test section 36, and judges whether non-equilibrium site test section 36 has received the signal for being intended to have detected that sensor tag 13 issued close to switch 14.Step S4 is moved in the case where having detected that sensor tag 13, and step S3 is repeated in the case where sensor tag 13 are not detected.

In step s 4, central control 31 reads amount of unbalance test section 35, obtains the acceleration horizontally and vertically that acceleration transducer 12 provides, and carry out scheduled operation, amount of unbalance M is calculated, and non-equilibrium site is detected by non-equilibrium site test section 36, moves to step S5.

In step s 5, central control 31 compares amount of unbalance M with the amount of unbalance setting value (m1) for being stored in memory 32, judges whether M > m1 is true.Step S6 is moved in the case where M > m1 is set up, moves to step S7 in the case where M > m1 is invalid.Amount of unbalance setting value (m1) is It can start the threshold value of the high-speed rotating scheduled amount of unbalance of rotating cylinder 5.In step s 5, M > m1 is invalid refers to that amount of unbalance M is the high-speed rotating value that can start rotating cylinder 5.In other words, the invalid imbalance for referring to rotating cylinder 5 of M > m1 is enhanced or is not present from the beginning.

In step s 6, the signal that water filling starts is sent to water filling control unit 38 by central control 31, starts to inject adjustment water to lifting rib 6.In addition, continuing to open the solenoid valve 26a~26c opened in initial step 6 in the case where the movement of step 6 is second circulation.

Specifically, central control 31 is as shown in figure 14 in the testing result of non-equilibrium site, in the case that washings agglomerate LD is present between lifting rib 6, some solenoid valve 26a~26c corresponding with the lifting rib 6 of opposed locations of washings agglomerate LD is located at is opened, starts to fill the water to the lifting rib 6 for being located at the position opposed with washings agglomerate LD.

Furthermore, central control 31 is as shown in figure 15 in the testing result of non-equilibrium site, in the case that washings agglomerate LD is present in a certain lifting rib 6 nearby, solenoid valve 26a~26c corresponding with the lifting rib 6 except the lifting rib 6 is opened, starts the lifting rib 6 except the lifting rib 6 being located near washings agglomerate LD and fills the water.Then, return step S3.

In the step s 7, central control gives the instruction notification for being intended to close solenoid valve 26a~26c to water filling control unit 38, stops providing adjustment water to lifting rib 6.Then step S8 is moved to.It should be noted that solenoid valve 26a~26c is the state being both turned off, therefore is done nothing without step S6, it is moved directly to step S8.

In step s 8, central control 31 starts to carry out the high speed rotation of rotating cylinder 5.It notifies specifically, central control 31 will be intended to start high-speed rotating signal to rotation speed control unit 33.Rotation speed control unit 33 is based on the notice and sends control signals to motor controling part 34, and motor controling part 34 is based on the control signal and is powered, and drives Rolling motor 10.Rotating cylinder 5 (is driven in rotation for 500rpm~800rpm) in the present embodiment with scheduled high speed revolving speed, moves to step S9 as a result,.

In step s 9, central control 31 reads non-equilibrium site test section 36, judges whether detect sensor tag 13 close to switch 14.Step S10 is moved in the case where judging that close switch 14 detects sensor tag 13, step S9 is repeated in the case where judging that sensor tag 13 are not detected close to switch 14.

In step slo, central control 31 reads amount of unbalance test section 35, obtains the acceleration horizontally and vertically that acceleration transducer 12 provides, carry out scheduled operation, amount of unbalance M is calculated, and non-equilibrium site is detected by non-equilibrium site test section 36, moves to step S11.

In step S11, central control 31 compares amount of unbalance M with the amount of unbalance setting value (m2) for being stored in memory 32, judges whether M > m2 is true.Step S12 is moved in the case where M > m2 is set up, moves to step S13 in the case where M > m2 is invalid.

Amount of unbalance setting value (m2) is the threshold value for the scheduled amount of unbalance that will not be led to the problem of the revolving speed of rotating cylinder 5 is increased to scheduled high speed revolving speed.In step s 11, M > m2 is invalid refers to that amount of unbalance M is the value of energy high speed rotation rotating cylinder 5.In other words, the invalid unbalanced degree for referring to rotating cylinder 5 of M > m2 is improved to can be carried out high speed rotation, or there is no the imbalances that can interfere high-speed rotating degree from the beginning.

In step s 12, the signal that water filling starts is sent to water filling control unit 38 by central control 31, starts to inject adjustment water to lifting rib 6.In addition, continuing to open the solenoid valve 26a~26c opened in initial step 12 in the case where the movement of step 12 is second circulation.

Specifically, central control 31 is as shown in figure 14 in the testing result of the non-equilibrium site of step S10, in the case that washings agglomerate LD is present between lifting rib 6, some solenoid valve 26a~26c corresponding with the lifting rib 6 of opposed locations of washings agglomerate LD is located at is opened, starts to fill the water to the lifting rib 6 for being located at the position opposed with washings agglomerate LD.

Furthermore, central control 31 is as shown in figure 15 in the testing result of the non-equilibrium site of step S10, in the case that washings agglomerate LD is present in some lifting rib 6 nearby, solenoid valve 26a~26c corresponding with the lifting rib 6 except the lifting rib 6 is opened, is started to the lifting rib 6 being located near washings agglomerate LD Except lifting rib 6 fill the water.Then, it is back to step S9.

In step s 13, central control 31 gives the instruction notification for being intended to close solenoid valve 26a~26c to water filling control unit 38, stops providing adjustment water to lifting rib 6.Then step S14 is moved to.It should be noted that solenoid valve 26a~26c is the state being both turned off, therefore is done nothing without step S12, it is moved directly to step S8.

In step S14, central control 13 reads timing unit (not shown), judges whether since rotating cylinder 5 reaches scheduled high speed revolving speed be more than the scheduled setting time for being dehydrated operating by the time.When by the time being more than the setting time of dehydration operating, step S15 is moved to, when being less than the setting time of dehydration operating by the time, return step 9.

In step 15, it notifies the signal for being intended to terminate dehydration operating to give rotation speed control unit, stops the rotation driving of Rolling motor 10.So terminate dehydration operating.

During so terminating dehydration operating, the adjustment water energy in lifting rib 6 being provided can repeat correctly to control as the slow rotation until rotation of rotating cylinder 5 stops all being discharged to the outside and return original state.

Pass through the process of above-mentioned dehydration operating, detect the scheme that simultaneously view eliminates non-equilibrium state to the non-equilibrium state of rotating cylinder 5 due to using the two stages in low speed rotation and when high speed rotation, the washing machine 1 that can either prevent vibration, the generation of noise during which from dehydration operation start to end can be designed.

More than, first embodiment of the invention is illustrated, but the structure of first embodiment is not limited to above structure, moreover it is possible to carry out various modifications.Such as, Figure 17 is the in-built schematic diagram for indicating the variation of first embodiment of the invention, as shown in figure 17, following scheme can also be used: separate branch pipe 116 from drainpipe 15 and recycled the dehydration liquid W for being trapped in 3 bottom of outer cylinder by pump 17, it is recycled as adjustment water, to increase economic efficiency.That is, can also be using using the dehydration liquid W come by 17 force feeds of pump as the structure for adjusting water and being provided to via solenoid valve 26a, 26b, 26c nozzle 25a, 25b, 25c.

It should be noted that, although above embodiment is made of using water receiving ring element 18 three guiding gutters 19a, 19b, 19c, and the structure there are three balancer 6 correspondingly is set, but the present invention is not limited thereto, can also be using the structure for having more than two multiple balancers 6 and guiding gutter corresponding with its quantity.

As described above in detail, washing machine 1 through the invention can provide adjustment water to lifting rib 6 by centrifugal force caused by the water receiving ring element 18 that rotates together with rotating cylinder 5 to eliminate the imbalance of rotating cylinder 5.Since the generation of the centrifugal force of the water receiving ring element 18 is unrelated with the configuration status of rotating cylinder 5, implementation of the invention is not limited to the horizontal cylinder formula washing machine of present embodiment, also can be implemented in vertical rotary cylinder, tilted drum-type washing machine.

Figure 18 is the explanatory diagram of the variation of water receiving ring element 18.Figure 19 is the assembling stereogram of the water receiving ring element 18 of Figure 18.

Water receiving ring element 18 forms a guiding gutter by the round water guiding ring 23 by being integrally molded so as section "U" font to realize and the ring flat-plate 20 and the comparable structure of bottom plate 21 in first embodiment.Guiding gutter 19a, 19b, 19c are formed by the overlapping of such molding water guiding ring 23, constitutes water receiving ring element 18A.Since the water guiding ring 23 constituted in this way is the same shape, therefore identical with first embodiment, centered on the axis S1 of rotating cylinder 5, guiding gutter 19a, 19b, 19c are configured with mutual 120 ° of differential seat angle bias, fixes tube rod 22a, 22b, 22c at the top of bias in bottom plate 21.Water receiving ring element 18 through such composition, so as to set freely eccentricity, eccentric range will not be limited as first embodiment by the amplitude of ring flat-plate 20.

In addition, Figure 20 is the cross-sectional view for indicating to be disposed in the other examples of lifting rib 6 of rotating cylinder 5, the hang plate 6c tilted down from front end towards rear end is provided in lifting rib 6.Dehydration operating terminates and the rotation speed of rotating cylinder 5 reduces, the centrifugal force in lifting rib 6 is also gradually decayed therewith, adjustment water becomes unaffected, it moves about, is discharged by gravity from tube rod 6b, at this time in lifting rib 6, by the inside that hang plate 6c is set in advance in lifting rib 6, the draining that can promote the adjustment water in especially horizontal cylinder, can efficiently be drained, and remaining will not adjust water in lifting rib 6.

Figure 21 is the explanatory diagram of the variation of water receiving ring element 18, by the way that bottom plate 21 is first formed as funnel-form as shown in figure 21 by the mounting portion of tube rod 22a, 22b, 22c, so as to improve the delay of adjustment water.

(second embodiment)

Figure 22~26 are the figures for indicating the washing machine 50 of second embodiment of the present invention.Figure 22 is the perspective view for the rotating cylinder 5 for indicating that the washing machine 50 of present embodiment has from the back side.Figure 23 is the exploded perspective view of guiding gutter 68.Hereinafter, being illustrated to the structure different from above-mentioned first embodiment.In addition, assigning identical appended drawing reference to structure same as the first embodiment in Figure 22~26.

In the present embodiment, the multiple guiding gutters 68 for constituting water receiving ring element 69 are not mutually eccentric, are configured to concentric circles.In addition, as shown in figure 22, guiding gutter 68 has water guide groove body 68a and bulge 68b.Water guide groove body 68a is the component for the section substantially "U" font that cyclic annular and inner peripheral surface is opened.The position near lifting rib 6 corresponding with each guiding gutter 68 bulge 68b, from the bottom of water guide groove body 68a, along the circumferential direction equally spaced protrusion is formed with multiple (a total of three in the present embodiment).Bulge 68b is connect via cylindric water flowing component 74 with lifting rib 6.Water receiving ring element 69 is configured to that guiding gutter 68 as multiple (being in the present embodiment three) is fixed with 5 concentric circles of rotating cylinder with overlap condition in the bottom 5c of rotating cylinder 5.

Such water receiving ring element 69 is constituted by assembling multiple plates as shown in figure 23.As multiple plates, the both ends of cylindric ring flat-plate 71, the first side plate 70 of disk-shaped multi-disc (being in the present embodiment two panels) with the excircle of approximately equal length with the excircle of ring flat-plate 71, substantially disk-shaped a pair of second side plate 72 with side plate main body 72b and protruding portion 72a and the band-like material of bending can be included and the bulging component 73 that constitutes.

Ring flat-plate 71 is equally spaced formed with the opening 71b or notch 71a for constituting aftermentioned connector in many places (in the present embodiment for three at) of circumferencial direction.Opening 71b is formed in the axis direction central portion of ring flat-plate 71, and notch 71a is formed in the axis direction both ends of ring flat-plate 71.

Second side plate 72 includes side plate main body 72b, and the length of excircle and inner periphery is roughly the same with the first side plate 70；And protruding portion 72a, it is prominent to the radial outside of side plate main body 72b.Protruding portion 72a sketches the contours of the approximate rectangular of gentle circular arc in jag 72a1, is equally spaced formed in many places (in the present embodiment for three at) along the circumferencial direction of side plate main body 72b.In addition, the protruding portion 72a of the side in a pair of second side plate 72, the notch 72a2 for constituting the arc-shaped of aftermentioned outlet pass 68b1 is formed in the one end of jag 72a1.Water flowing component 74 is connected in notch 72a2.

These plates are clamped the ring flat-plate 71 for being embedded with the first side plate of two panels 70 by the second side plate 72 of a pair in a manner of keeping protruding portion 72a Chong Die with opening 71b or notch 71a, and then bulging component 73 is installed between a pair of of protruding portion 72a, 72a, to be integrated.As a result, using ring flat-plate 71 as bottom surface, with the first side plate 70 And second side plate 72 or the first side plate of two panels 70 be used as bottom wall, and be overlapped three guiding gutters 68 for being formed with bulge 68b by protruding portion 72a and bulging component 73, water receiving ring element 69 be consequently formed.

Figure 24 is the partial cross-sectional perspective view for cutting off guiding gutter 68 at the cross section including bulge 68b.The bulge 68b of guiding gutter 68 is as shown in figure 24, there is the outlet pass 68b1 connected for water flowing component 74 shown in Figure 22 in the leading side of the direction of rotation X of rotating cylinder 5, there is the 68a1 that is open with the connection being connected to inside water guide groove body 68a in the lag side of the direction of rotation X of rotating cylinder 5.Connection be open 68a1 it is bigger than outlet pass 68b1, be open about 2/3rds degree of bulge 68b from one end of bulge 68b towards direction of rotation X.

The water guide groove body 68a of adjustment water to such guiding gutter 68 is injected as desired by nozzle unit 25 in dehydration, but it is some how much the adjustment water of injection can be come up in high-speed rotating water guide groove body 68a by volume, and overwhelming majority adjustment water can stay in the lower part of water guide groove body 68a.Moreover, when bulge 68b rotate to constitute water receiving ring element 69 lower part position when, via connection be open 68a1, adjustment water flowed down in bulge 68b.Then, adjustment water is pushed to the side wall 6862 positioned at direction of rotation X lag side of bulge 68b, the outlet pass 68b1 positioned at the leading side direction of rotation X is smoothly flowed therein by centrifugal force, is provided in lifting rib (bag body lifting rib) 6 by hydraulic pressure via water flowing component 74.

So, guiding gutter 68 has cricoid water guide groove body 68a and from water guide groove body 68a to radial outside bulge 68b outstanding, bulge 68b is formed with the opening 68a1 connecting with water guide groove body 68a in the direction of rotation X lag side of rotating cylinder 5, in direction of rotation, the leading side X is connected with water flowing component 74, thus, utilize gravity and centrifugal force, adjustment water from bulge 68b can efficiently be flowed into water flowing component 74 and lifting rib 6, the bias due to washings can be eliminated in a short time and the imbalance (load partially) that generates.

Figure 25 is that washing machine 50 is cut off to the vertical profile perspective view being indicated near nozzle unit 25.As shown in figure 25, in the present embodiment, the lower part (lower part of rotating cylinder 5) of water receiving ring element 69 is provided with the nozzle unit 25 with nozzle 25a~25c, adjusts water by these nozzles 25a~25c and is injected into water guide groove body 68a from above along direction of rotation X.Such nozzle unit 25 is configured at the position that can be supplied water towards guiding gutter 68 in the lower part of water receiving ring element 69, water supply position is set in the lower part of rotating cylinder 5, thus, the water guide groove body 68a of high-speed rotating guiding gutter 68 can be gently filled the water by water is adjusted by nozzle unit 25, can make to be difficult to happen powder-refining with water when injection and splash.

Figure 26 is the figure for indicating the lifting rib 6 being disposed in rotating cylinder 5.Specifically, Figure 26 (a) is the vertical profile perspective view for nearby carrying out local display to the lifting rib 6 of washing machine 50, Figure 26 (b) is to indicate The perspective view of lifting rib 6, Figure 26 (c) are that lifting rib 6 is cut off the cross-sectional view being indicated along the direction orthogonal with its longitudinal direction.

As shown in figure 26, in the present embodiment, it is provided with the partition member (interval) 56 for collapsing the aquifer zones T inside lifting rib 6 along the direction of rotation (circumferencial direction) of rotating cylinder 5.The partition member 56 is the box-like component being open towards the axis S1 (referring to Fig. 2) of rotating cylinder 5, and the length of the length and the longitudinal direction of lifting rib 6 of longitudinal direction is roughly equal.In addition, the length W1 of the partition member 56 on the direction of rotation of rotating cylinder 5 is configured to the half or so of the length W2 of the lifting rib 6 on the direction of rotation of rotating cylinder 5.In addition, in the present embodiment, in one end face of longitudinal direction of lifting rib 6, near the opening edge 56a of partition member 56, the water supply opening 6e being inserted into for water flowing component 74 is formed with as shown in Figure 26 (a).

The adjustment water for flowing into such lifting rib 6 via water flowing component 74 is stored in the partition member 56 for being configured at the direction of rotation central portion of lifting rib 6 until influx is more than the capacity of partition member 56.Thus, as in Figure 26 (c) as shown in dotted line, since adjustment water concentrates on the narrow range on the direction of rotation of lifting rib 6, therefore as used in Figure 26 shown in double dot dash line, compared with the case where adjustment water is provided into the lifting rib 6 for not having partition member 56, the diffusion of the adjustment water of the direction of rotation of rotating cylinder 5 can be inhibited.Although the centrifugal force for being applied to adjustment water when dehydration is the resultant force for being respectively acting on the centrifugal force of water of distribution, but since adjustment water is also the narrow zone for focusing on the direction of rotation of rotating cylinder 5, the direction of centrifugal force can more be drawn close so that resultant vector becomes larger, therefore can efficiently eliminate the inclined load of washings with lesser amount of adjustment water.When the supply amount for adjusting water is more than the capacity of partition member 56, adjustment water is overflowed from the open end 56a of partition member 56, is inwards gradually accumulated from the radial outside of rotating cylinder 5.Then, when for example in order to terminate be dehydrated and reduce the rotation speed of rotating cylinder 5, when centrifugal force becomes smaller, the adjustment water in the lifting rib 6 on the top of rotating cylinder 5 flows to axis S1 (referring to Fig. 2) side by gravity, is expelled to outside lifting rib 6 via water flowing component 74.

Due to being equipped with the partition member 56 for collapsing the aquifer zones T inside lifting rib 6 along the circumferencial direction of rotating cylinder 5 like this, therefore adjustment water can be focused on into the narrow range on the direction of rotation of rotating cylinder 5 in lifting rib 6, it can be with the lesser amount of imbalance for adjusting water and eliminating the bias due to washings in a short time and generating.

Figure 27,28 are the flow charts for indicating the control of washing machine 50 of such second embodiment.Figure 29 is the figure for the control flow for illustrating the dehydration operating of washing machine 50.

In the present embodiment, when the central control 31 receives the input signal from dehydration button (not shown) or receives the signal for being intended to start dehydration in washing mode operating, SP1 is entered step, dehydration is started.It should be noted that in the present embodiment, being omitted about the control between each component as documented by first embodiment in control unit 30.

In step SP1, central control 31 makes spinning up for rotating cylinder 5 after inverting rotating cylinder 5 slowly.

In step SP2, central control 31 is based on low speed rotation setting value (N1), makes 5 low speed rotation of rotating cylinder.

In step SP3, the acceleration value (x-component of acceleration transducer) that central control 31 is provided based on acceleration transducer 12 is detected amount of unbalance (M).

In step SP4, amount of unbalance (M) is compared by central control 31 with the amount of unbalance setting value (ma) for being stored in memory 32, judges whether M < ma is true.When judging that M < ma is set up, SP6 is entered step.On the other hand, when judging that M < ma is invalid, SP5 is entered step.Here, amount of unbalance setting value (ma) is to indicate that the bias degree of washings arrives greatly the threshold value for being difficult to eliminate providing and adjusting water to lifting rib 6.That is, the case where entering step SP5 refers to that judging that the bias degree of washings arrives greatly is difficult to the case where eliminating providing and adjusting water to lifting rib 6.

In step SP5, central control 31 is after the rotation for making rotating cylinder 5 stops, return step SP1, repeats step S1~S4.

In step SP6, central control 31 judge from start low speed rotation after by the time be progress low speed rotation processing scheduled setting time more than when, enter step SP7.

In step SP7, central control 31 is based on high speed rotation setting value (N2), makes 5 high speed rotation of rotating cylinder.

In step SP8, the acceleration value that central control 31 is provided based on acceleration transducer 12 detects amount of unbalance (M) and non-equilibrium site (N).

In step SP9, solenoid valve X, region Y shown in Figure 29, solenoid valve Z are replaced into the value of parameter list according to non-equilibrium site (N) by central control 31.In Figure 29, also by the cross section of rotating cylinder 5 along the circumferential direction six equal part, and the positional relationship with lifting rib 6 is schematically shown, the lifting rib 6 for being marked as 25a indicates to be provided the lifting rib 6 for adjusting water by nozzle 25a shown in Figure 25.Equally, the lifting rib 6 for being marked as 25b indicates the lifting rib 6 that adjustment water is provided by nozzle 25b shown in Figure 25, and the lifting rib 6 for being marked as 25c indicates the lifting rib 6 that adjustment water is provided by nozzle 25c shown in Figure 25.

In step SP10, central control 31 makes the solenoid valve X recorded in the parameter list of Figure 29 be open.For example, solenoid valve X is the solenoid valve 25c of the corresponding lifting rib 6 opposed with region I in the case that non-equilibrium site (N) is region I.Adjustment water is provided as a result, to lifting rib 6 corresponding with solenoid valve X, and the amount and position loaded partially changes.

In step SP11 shown in Figure 28, the acceleration value that central control 31 is provided based on acceleration transducer 12 calculates amount of unbalance (M) and non-equilibrium site (N) again.

In step SP12, amount of unbalance (M) is compared by central control 31 with the amount of unbalance setting value (ma) for being stored in memory 32, judges whether M < ma is true.When judging that M < ma is set up, SP13 is entered step.On the other hand, when judging that M < ma is invalid, into subsequent steps SP21.That is, when the bias degree for judging washings arrive greatly even if provide adjust water to lifting rib be difficult to eliminate when, enter step SP21.

In step SP13, amount of unbalance (M) is compared by central control 31 with the amount of unbalance setting value (mb) for being stored in memory 32, judges whether M < mb is true.When judging that M < mb is set up, into subsequent steps SP23.On the other hand, when judging that M < mb is invalid, SP14 is entered step.Here, amount of unbalance setting value (mb) is the small value of specific unbalance amount setting value (ma), it is to indicate the small threshold value to the degree that will not generate noise not providing adjustment water to lifting rib 6 of the bias of washings.That is, judgement load partially it is small or be not present even if not to lifting rib 6 supply water will not generate noise in the case where, enter step SP23.

In step SP14, central control 31 judge since opening solenoid valve X by the time to be more than setting time when, enter step SP15.Here, the setting time is to fill the required time until being adjusted water in a lifting rib 6.

In step SP15, central control 31 judge non-equilibrium site (N) whether region Y represented by the parameter list for being Figure 29.When judging non-equilibrium site (N) for region Y, SP16 is entered step.When judging non-equilibrium site (N) not for region Y, return step SP11.For example, in the case that the initial non-equilibrium site (N) in step SP11 is region I, hereafter, as long as non-equilibrium site (N) is region I, return step SP16 always without calculating again.Since the result calculated again in step SP16 is varied over when solenoid valve X supplies water, therefore when the weight of lifting rib 6 corresponding with solenoid valve 25c increases, non-equilibrium site (N) becomes region V from region I, when step SP15 is repeated several times, non-equilibrium site (N) becomes region Y.

In step SP16, central control 31 closes solenoid valve X documented by the parameter list of Figure 29, and opens solenoid valve Z.Such as, in the case where initial non-equilibrium site (N) is region I, solenoid valve X is the solenoid valve 25c corresponding to the lifting rib 6 opposed with region I, and solenoid valve Z is the solenoid valve 25b for corresponding to the lifting rib 6 of the position than lifting rib 6 corresponding with solenoid valve 25c closer to region I.Adjustment water is provided to lifting rib 6 corresponding with solenoid valve Z as a result, and the amount and position loaded partially changes.

In step SP17, the acceleration value that central control 31 is provided based on acceleration transducer 12 calculates amount of unbalance (M) and non-equilibrium site (N) again.

In step SP18, amount of unbalance (M) is compared by central control 31 with the amount of unbalance setting value (ma) for being stored in memory 32, judges whether M < ma is true.When judging that M < ma is set up, SP19 is entered step.On the other hand, when judging that M < ma is invalid, into subsequent steps SP21.That is, entering step SP21 when being difficult to eliminate the bias degree for judging washings arrives greatly even if offer more adjustment water to lifting rib 6.

In step SP19, amount of unbalance (M) is compared by central control 31 with the amount of unbalance setting value (mb) for being stored in memory 32, judges whether M < mb is true.When judging that M < mb is set up, into subsequent steps SP23.That is, when judging the degree loaded partially by entering step SP23 to the water supply of lifting rib 6 elimination to when will not generate noise.On the other hand, when judging that M < mb is invalid, SP20 is entered step.

In step SP20, central control 31 judge since opening solenoid valve Z by the time to be more than above-mentioned setting time when, into subsequent steps SP21.On the other hand, when judging the process time since opening solenoid valve Z is not setting time or more, return step SP17.

In step SP21 shown in Figure 27, central control 31 is in off state all solenoid valve X, Y, Z.

In step SP22, central control 31 is after the rotation for making rotating cylinder 5 stops, return step SP1.

In this way, carrying out the processing of step SP21,22, the first step starts to be carried out dehydrating again in the case where the degree that judgement loads partially arrives greatly will not eliminate by the water supply to lifting rib 6.

In step SP23 shown in Figure 28, central control 31 is in off state all solenoid valve X, Y, Z.

In step SP24 shown in Figure 28, central control 31 makes rotating cylinder 5 rotate the stipulated time with maximum speed, is carried out dehydrating.Then, terminate dehydration.

So, in the present embodiment, first, only to positioned at the position farthest from the non-equilibrium site (N) being initially detected, the lifting rib 6 being affected by the adjustment of amount of unbalance (M) and position (N) supplies water, at the end of the water supply to the lifting rib 6, the variation of the amount of unbalance (M) and position (N) that occur due to the water supply is considered, while carrying out the water supply to second lifting rib 6 as needed.Thus, the case where without the concern for as supplying water simultaneously to multiple lifting ribs 6, since the resistance etc. of the wall surface of guiding gutter 68 causes to adjust the case where water is not supplied to each lifting rib 6 quantitatively, it is poor to the feed rate of each lifting rib 6 to adjust by the opening and closing of solenoid valve 16 not need, therefore the opening and closing number of solenoid valve 16 is less, can inhibit the reduction of the Durability of solenoid valve 16.

More than, second embodiment of the present invention is illustrated, but the structure of second embodiment is not limited to above structure, can be carried out various modifications.

For example, as shown in figure 30, it can be using the structure for being provided with multiple water storage boxes (bag) 80 as water storage portion in the bottom 5c of rotating cylinder 5.Figure 30 is the figure for indicating the variation of second embodiment.Specifically, Figure 30 (a) is the perspective view for indicating variation from the bottom 5c of rotating cylinder 5, Figure 30 (b) is the partial cross-sectional perspective view cutting off above-mentioned variation near water storage box 80 and lifting rib 6 and being indicated.Water storage box 80 is the radial outside in water receiving ring element 69 and the hollow part that is configured in position corresponding with each lifting rib 6 using 69 blind area of water receiving ring element.Water storage box 80 is connected to via communication port 80a with corresponding lifting rib 6, and adjustment water is flowed by centrifugal force from lifting rib 6.The adjustment water flowed into water storage box 80 is expelled to lifting rib 6 via communication port 80a when the rotation speed of rotating cylinder 5 reduces so that centrifugal force becomes smaller.

So, by the direction the axis S1 end face for being mounted on the outer surface of rotating cylinder 5, specifically it is mounted on the bottom 5c of rotating cylinder 5, and there are the multiple water storage boxes 80 as water storage portion being respectively communicated with multiple lifting ribs 6, to increase the capacity of lifting rib 6 using water storage box 80, more adjustment water can be absorbed, even if also can restfully eliminate inclined load in the biggish situation of washings agglomerate in dehydration.

The present invention is constituted in addition it is also possible to which the structure of the structure of first embodiment and second embodiment is combined with each other.

In turn, the structure of above embodiment can be applied to vertical washing machine, in this case, it is configured to the lower section configuration water receiving ring element of the cylindric washer for example extended in axis toward up and down direction, and upper surface or the lower surface opening for making guiding gutter, provide adjustment water to guiding gutter from above or below.
