Hereinafter, with operating process and the effect of description according to the control method of the washing machine of embodiment.

Fig. 4 A and Fig. 4 B are the flow charts that illustrates according to the operation of the control method of the washing machine of embodiment, and refer to the algorithm that can improve scourability and perceptual quality except basic wash cycle by the generation of adding bubble.

In Fig. 4 A to Fig. 4 B, the user puts into clothing in cylinder 12, also washing agent is put in detergent supply device 20.Then, be arranged on the button of the input block 70 on control panel 40 by manipulation, select washing process (100) from standard procedure, wool process and soft process, for example, the user is according to the standard procedure of the type selecting of clothing.At this moment, the activation bit of the washing process of user's selection is imported in control module 72 by input block 70.

Therefore, control module 72 detects the weight (that is, load) of putting into the clothing in cylinder 12, to carry out wash cycle (102).At this moment, the method as the weight of measuring clothing has following method: the time span that reaches predetermined speed or predetermined number of revolutions by the instantaneous acceleration measurement washing motor 15 with washing motor 15 detects the weight of clothing; Perhaps as disclosed in 2002-336593 Japanese publication, 2004-267334 Japanese publication and 07-90077 Japanese publication, continue predetermined amount of time by washing motor 15 being applied moment of torsion, then by utilizing second law of motion (moment of torsion=inertia * acceleration) directly or indirectly to measure the moment of inertia of cylinder 12, thereby measure the method for the weight of clothing.

Except above description, the weight of clothing (that is, load) also can detect by the working load unit.

When the weight that detects clothing (namely, the amount of load) time, control module 72 according to the weight of the clothing that detects (namely, the amount of load) Offered target water level, target rinsing water level, target RPM, the target drives factor (that is, the target On/Off time of motor), wash time and rinsing time (104).

The expression user that arranges of target water level, target rinsing water level, target RPM, the target drives factor (that is, the target On/Off time of motor), wash time and rinsing time does not have input in addition with reference to the situation of the independent order of the operation of washing machine 1.In the situation that the user inputs the independent order with reference to the operation of washing machine in addition, according to the weight of clothing (namely, the amount of load) target water level, target rinsing water level, target RPM, the target drives factor (that is, the target On/Off time of motor), wash time and the rinsing time that arranges changes according to user's order.

Then, the wash time of the washing process selected by consideration of control module 72 determines that the standard of Bubble formation circulation carries out number of times " Ns " (106).

The standard of Bubble formation circulation is carried out number of times " Ns " and is set at least twice, and according to the wash time of each washing process, the standard that changes the Bubble formation circulation is carried out number of times " Ns ".For example, when the wash time overtime, carry out number of times " Ns " by the standard that increases the Bubble formation circulation, scourability is improved, and the observability of the bubble of user's impression simultaneously also strengthens.

Then, control module 72 is according to the weight (that is, the amount of load) of clothing or user's command driven cold valves 33 or hot water valve 34, with the required water (that is, washings) of supply wash cycle.

When cold valves 33 or hot water valve 34 when driven, cold valves 33 or hot water valve 34 are opened, water (that is, washings) by the supply of external water supply pipe is supplied to bucket 11 after through cold feed pipe 31 or hot water supply pipe 32 and process detergent supply device 20.At this moment, the washing agent of detergent supply device 20 inside by water (namely, washings) dissolving, and in being introduced into afterwards bucket 11 through tube connector 35 together with water (that is, washings), therefore, detergent water (namely, the water that mixes with washing agent) be supplied to bucket 11 bottom (that is, specifically, between bucket and cylinder) (108).

Therefore, control module 72 is by using level sensor 16 to detect the water level that is fed to the water in bucket 11, judge whether the water level that is fed to the water in bucket 11 is positioned at the target water level (namely, the water level definite according to predetermined laundry amounts), and continue the action of supplying water, reach the target water level until be fed to the water level of the water in bucket 11.

When operating the water level that is fed to the water of bucket in 11 by water supply and reach the target water level, control module 72 stops by stopping cold valves 33 or hot water valve 34 operation of supplying water.

When the supply of washings (that is, detergent water) is completed and when reaching the target water level, circulation and the rotation of the cylinder 12 Bubble formation circulation (110) that produce a large amount of bubbles of control module 72 by using washings (that is, detergent water).

Basic wash cycle refers at supplying detergent water (namely, washing agent mixes with washings) afterwards, by with target RPM and the target drives factor (namely, the On/Off time of motor) drive washing motor 15, make cylinder forward and oppositely alternately rotation, and wash during predetermined wash time by the motion of using clothing and the current that produced by cylinder 12 forwards and reverse alternately rotation, wherein, target RPM and the target drives factor are all according to the weight (that is, the amount of load) of clothing and be set.

On the contrary, Bubble formation cyclic representation at supplying detergent water (namely, the washings that mix with washing agent) afterwards by driving pump 51 make the bucket 11 inside water (namely, detergent water) circulation, by with predetermined RPM(namely, speed is the RPM of about 80RPM to 89RPM simultaneously) and the motor of about 14 seconds open/the driving factor that the motor of about 6 seconds cuts out drives washing motor 15 to be made cylinder 12 forwards and oppositely alternately rotates.As above-mentioned result, thereby the water between 11 circulates and again is introduced in bucket 11 when inner when cylinder 12 and bucket, along with the rotation of cylinder 12 produces a large amount of bubbles by friction, detergent dissolution is accelerated as a result, and because the dividing plate of the bubble that produces towards the door 19 of the front surface that is positioned at cylinder 12 overflows, so improved the perceptual quality that the user experiences for the washing performance the subject of knowledge and the object of knowledge in washing process.During washing, the direction of the flow path of flow path transfer valve 52 is changed to towards circulating path 56a, along with the driving of pump 51 is not discharged into the outside from the water of bucket 11 pumpings, but is re-introduced in bucket 11 by circulation pipe 56.

Execution about the algorithm of Bubble formation circulation will be described in detail by reference Fig. 5 and Fig. 6.

At this moment, whether control module 72 is (112) by being counted to determine predetermined amount of time (that is, time period of about 1 minute to 2 minutes, and be known as hereinafter for the 5th time period) the carrying out time of Bubble formation circulation if expiring.

If as operation definite result of 112, the 5th time period (that is, the time period of about 1 minute to 2 minutes) does not expire, control module 72 is back to the operation 110 promoting the circulation of qi bubble of going forward side by side and produces circulation, until the 5th time period expired.

If the definite result as operation 112, the 5th time period expired, control module 72 stops the Bubble formation circulation, and the number of times " N " (that is the number of times that, by driving pump and washing motor, drum rotating and water is recycled) that carries out of Bubble formation circulation is counted (114).

As mentioned above, after a large amount of bubbles of generation that circulate by Bubble formation, control module 72 is by with target RPM(namely, speed is the RPM of about 40RPM to 50RPM) and to drive the factor (namely, the On/Off time of motor) drive washing motor and make cylinder 12 forwards and oppositely alternately rotation, produce with detergent water (namely, the washings that mix with washing agent) be delivered to the current of clothing, thereby carry out substrate wash cycle (116), wherein, target RPM and the target drives factor all are determined in advance for wash cycle.

Be applied at a large amount of bubbles that produce of circulate by Bubble formation due to basic wash cycle under the state on the clothing of cylinder 12 inside and carry out, thus scourability improved, and also improved the observability of the bubble that the user experiences simultaneously.

At this moment, control module 72 was counted by the time that Bubble formation circulation is stopped, and whether determining predetermined amount of time (that is, producing at the dissipation of air bubbles promoting the circulation of qi bubble that advances the required predetermined amount of time of about 5 minutes that circulates), (118) expire.

After expiring in about 5 to 6 minutes, the a large amount of dissipation of air bubbles that produce along with the carrying out of Bubble formation circulation, therefore need to be at predetermined amount of time (namely, the predetermined amount of time of about 5 minutes, be known as hereinafter for the 6th time period) in again carry out Bubble formation circulation, thereby remain on the bubble that cylinder 12 inside apply.

If as operation definite result of 118, the 6th time period (that is, the time period of about 5 minutes) does not expire, control module 72 is back to the operation 116 promoting the circulation of qi bubble of going forward side by side and produces circulation, until the 6th time period expired.

If the definite result as operation 118, the 6th time period expired, control module 72 stops basic wash cycle, and determine the carrying out number of times " N " and whether arrive predetermined standard and carry out number of times " Ns " (namely of Bubble formation circulation of counting, the optimality criterion of about 2 to 4 times is carried out number of times, carry out number of times according to optimality criterion, the dissolving of washing agent is accelerated according to the wash time of each washing process, and carry out number of times according to optimality criterion, can improve the observability of the bubble of user's impression) (120).

If the definite result as operation 120, the number of times " N " that carries out of Bubble formation circulation does not reach predetermined standard and carries out number of times " Ns ", control module 72 is back to operation 110, to carry out making by driving pump 51 the Bubble formation circulation of water circulation, until the number of times " N " that carries out of Bubble formation circulation reaches the predetermined standard of determining according to the wash time of each washing process and carry out number of times " Ns ", and make cylinder 12 forwards and oppositely alternately rotate by forward and reverse drive washing motor 15 towards washing motor 15 simultaneously.

As mentioned above, if the number of times " N " that carries out of Bubble formation circulation reaches predetermined standard and carries out number of times " Ns ", control module 72 finishes the Bubble formation circulation, and with target RPM(namely, speed is the RPM of about 40RPM to 50RPM) and drive the factor (namely, the On/Off time of motor) drive washing motor 15, wherein, target RPM and the driving factor all are determined in advance so that wash section remaining time that continues to carry out wash time.Make cylinder 12 forwards and oppositely alternately rotation by the driving according to washing motor 15, produce the current that detergent water (that is, the washings that mix with washing agent) are delivered to clothing, to carry out basic wash cycle (122).

Then, control module 72 is determined wash time predetermined according to the weight of clothing whether expire (124).

If as definite result of operation 124, wash time does not expire, control module 72 is back to operation 122 and carries out basic wash cycle, until remaining wash time expires.

If as definite result of operation 124, wash time expires, control module 72 stops washing motor 15, and discharging detergent water (that is, the washings that mix with washing agent) (126) then carries out interim rotary dehydration (128).When carrying out draining, the direction of the flow path of flow path transfer valve 52 is changed to towards discharge flow path 55a, thereby the water of discharging from bucket 11 according to the driving of pump 51 is not introduced in bucket 11, but is discharged into the outside by drainpipe 55.If the direction of the flow path of flow path transfer valve 52 normal time (namely, in the time except the wash time section) be in the state that is changed to towards discharge flow path 55a, the direction of the flow path of flow path transfer valve 52 does not need to be changed, and in this case, do not need to operate flow path transfer valve 52 by driver element 74.

Then, control module 72 driving cold valves 33 or hot water valve 34 are with the required water (that is, washings) of supply rinse cycle.

When driving cold valves 33 or hot water valve 34, cold valves 33 or hot water valve 34 are opened, and water (that is, washings) is supplied in bucket 11 (130) after through cold feed pipe 31 or hot water supply pipe 32.At this moment, control module 72 will supply water to operate and be controlled to be the replacement water supply operation that is configured to supply washings, make simultaneously cylinder 12 forwards and oppositely alternately rotate to improve rinsing performance, thereby make the clothing that is snarled in cylinder 12 released to mix well with water, therefore, obtained to improve the effect of rinsing performance.

Therefore, control module 72 is by using level sensor 16 to detect the water level that is fed to the water in bucket 11, determine whether the water level that is fed to the water in bucket 11 is in target rinsing water level (namely, according to the definite water level of predetermined laundry amounts), and proceed the operation of supplying water, reach target rinsing water level until be fed to the water level of the water in bucket 11.

Seasonable to the confession of target rinsing water level when completing washings, control module 72 is with target RPM and drive the factor (namely, the On/Off time of motor) drive washing motor 15, thereby carry out rinse cycle (132), wherein, target RPM and drive the factor and all be determined in advance for rinse cycle so that cylinder 12 alternately forward and reverse rotation and generation make the current of washings and contact with clothing.

When completing rinsing in predetermined rinsing time, control module 72 stops washing motor 15, discharge water (that is, washings) (134).Such rinse cycle be repeated to be scheduled to carry out number of times.

When be scheduled in rinse cycle carry out number of times the time when completing last rinse cycle, control module 72 determines whether current circulation is rotary dehydration circulation (136).

If as operation definite result of 136, current circulation is not the rotary dehydration circulation, and control module 72 is back to operation 128 and carries out interim rotary dehydration, then carries out ensuing operation.

If as operation definite result of 136, current circulation is the rotary dehydration circulation, control module 72 with predetermined final rotary dehydration RPM(greatly in the scope of 700RPM to 1000RPM) be rotated dewatering cycle (138).

In the Bubble formation cyclic process, be constructed such that cylinder 12 alternately the driving of the washing motor 15 of forward and recycled back distribute shown in Figure 5.

Fig. 5 illustrates the curve map that the driving of washing motor in the Bubble formation circulation according to the washing machine of embodiment distributes.

In Fig. 5, circulate about Bubble formation, at water (namely, washings) after being supplied in cylinder 12, by making cylinder 12 alternately forward and reverse rotation, water between cylinder 12 and bucket 11 (namely, in particular to detergent water) locate to produce and rub, washing motor 15 remains in predetermined RPM(namely simultaneously, speed is the RPM of about 80RPM to 89RPM, produce friction with this RPM and can produce bubble by friction between water and cylinder and bucket), and with the motor of about 14 seconds open/the driving factor that the motor of about 6 seconds cuts out drives.By the water between cylinder 12 and bucket 11 (namely, detergent water) friction produces a large amount of bubbles, the a large amount of bubbles that produce have accelerated the dissolving of washing agent, and because the dividing plate of a large amount of bubbles towards the door 19 of the front surface that is positioned at cylinder 12 overflows, so the perceptual quality that the user experiences for the washing performance the subject of knowledge and the object of knowledge in washing process is improved.

Begin such Bubble formation circulation after the supply of completing washings.In order to produce bubble, when the diameter of cylinder 12 is about 500 ± 50mm, the RPM of washing motor 15 take speed as about 80RPM to 89RPM is driven surpasses 1 minute (approximate about 1 minute to 2 minutes), and at this moment, do not carry out in a continuous manner the driving of washing motor 15, but the opening time of repeated washing motor 15 and shut-in time, as shown in Figure 5.Shut-in time be configured to by cylinder 12 stop and driving causes other turbulization, rather than by making the alternately turbulent flow that causes of forward and reverse rotation of cylinder 12, and the shut-in time also be configured to provide the bubble that the makes generation time towards the dividing plate of the door 19 of the front surface that is positioned at washing machine moves.

Predetermined RPM(for generation of bubble is, RPM in the scope of about 80RPM to 89RPM) be configured to higher than washing RPM(namely, RPM in the scope of about 40RPM to 50RPM), and be configured to lower than rotary dehydration RPM(namely, higher than the RPM of 700RPM).

In addition, dissipate after about 5 to 6 minutes by the Bubble formation bubble that produces that circulates, therefore by approximately with forward and reverse over-over mode, cylinder 12 additionally being rotated in maximum 5 minutes, producing a large amount of bubbles, thereby can keep the observability of bubble.

Next, the process of the algorithm of Bubble formation circulation will be described by reference Fig. 6.

Fig. 6 is the flow chart that illustrates according to the operation of the Bubble formation of embodiment circulation.

In Fig. 6, seasonable when the confession of completing cylinder 12 and the water (that is, detergent water) of bucket between 11, control module 72 is by driving flow path transfer valves 52 through driver element 74, and the direction of flow path is changed to be become towards circulating path 56a(200).When the direction of the flow path of flow path transfer valve 52 is changed to when circulating path 56a, loop structure is configured such that can not be discharged into the outside from the water that bucket 11 is discharged, but is re-introduced in bucket 11 by circulation pipe 56.

Direction at the flow path of working as flow path transfer valve 52 is changed under the state that circulates path 56a, control module 72 is by driver element 74 driving pumps 51, and the predetermined RPM(take speed as about 80RPM to 89RPM is hereinafter, is called Bubble formation RPM) towards forward drive washing motor 15(201).

Then, the driven and washing motor 15 of 72 pairs of pumps 41 of control module is counted in driven time period of forward with Bubble formation RPM, and whether (202) thereby determine predetermined very first time section (for about 14 seconds) if expiring.

If as operation definite result of 202, very first time section does not expire, control module 72 is back to operation 201 and driving pump 51, with Bubble formation RPM towards forward drive washing motor 15, until very first time section expires.

As mentioned above, when driving pump 51, water between cylinder 12 and bucket 11 (namely, detergent water) be recycled by circulation pipe 56, and the downside in bucket 11 is introduced into, and when in very first time section (being about 14 seconds) with Bubble formation RPM during towards forward drive washing motor 15, cylinder 12 is strongly rotation facing one direction.According to the rotation of the brute force of cylinder 12, the water place be introduced in bucket 11 by circulation pipe 56 in produces and rubs, and consequently, turbulization.Turbulent flow by the rotation by water circuit and cylinder 12 produces produces bubble, thereby accelerates the dissolving of washing agent.

If the definite result as operation 202, very first time section expires, control module 72 makes pump 51 and washing motor 15 stop (204) by driver element 74, then count by the time period that pump 51 and washing motor 15 are stopped experiencing, determine whether predetermined the second time period (for about 6 seconds) (206) expire.

If as definite result of operation 206, the second time period did not expire, control module 72 is back to operation 204 and pump 51 and washing motor 15 is stopped, until the second time period expired.

As mentioned above, after forward drive washing motor 15, when washing motor 15 stopped having continued the second time period when (for about 6 seconds), except the turbulent flow that the rotation of cylinder 12 produces, cause the turbulent flow that produces in addition when process that cylinder 12 repeats to stop and driving, and because the dividing plate of the bubble that produces towards the door 19 of the front surface that is positioned at washing machine 1 moves, so improved the perceptual quality that the user experiences for the washing performance the subject of knowledge and the object of knowledge in washing process.

If as operation definite result of 206, the second time period expired, control module 72 is by driver element 74 driving pumps 51, and with Bubble formation RPM towards reverse drive washing motor 15(208).

Then, the driven and washing motor 15 of 72 pairs of pumps 51 of control module is counted towards reverse driven time period with Bubble formation RPM, thereby determines very first time section whether expire (210).

If as operation definite result of 210, very first time section does not expire, control module 72 is back to operation 208 with driving pump 51, simultaneously with Bubble formation RPM towards reverse drive washing motor 15, until very first time section expires.

As mentioned above, when driving pump 51, water between cylinder 12 and bucket 11 (namely, detergent water) be recycled by circulation pipe 56, and the downside in bucket 11 is introduced into, and when take Bubble formation RPM in very first time section (as about 14 seconds) during towards reverse drive washing motor 15, cylinder is by towards oppositely strongly rotation.At this moment, under the state that produces other turbulent flow, according to the effect towards the rotation of the brute force of reverse cylinder 12, produce power friction at the water place that is being introduced in bucket 11 inside by circulation pipe 56, result produces stronger turbulent flow.Strong turbulence by the rotation towards reverse cylinder 12 produces produces a large amount of bubbles, thereby accelerates detergent dissolution.

If the definite result as operation 210, very first time section expires, control module 72 makes pump 51 and washing motor 15 stop (212) by driver element 74, then count by the time period that pump 51 and washing motor 15 are stopped experiencing, thereby determine the second time period whether expire (214).

If as definite result of operation 214, the second time period did not expire, control module 71 is back to operation 212 and pump 51 and washing motor 15 is stopped, until the second time period expired.

As mentioned above, after reverse drive washing motor 15, when washing motor 15 stops lasting the second time period (for about 6 seconds), except passing through cylinder 12 towards the strong turbulence that reverse rotation produces, when repeating to stop and driving, cylinder 12 causes the turbulent flow of generation in addition, and because the dividing plate of the bubble that produces towards the door 19 of the front surface that is positioned at washing machine 1 overflows, so the observability of the bubble that the raising user experiences.

If as definite result of operation 214, the second time period expired, control module 72 is counted (216) towards forward and reverse driving to the carrying out time period of Bubble formation circulation according to driving and the washing motor 15 of pump 51.

Then, control module 72 proceeds to operation 112, and determines whether the carrying out time period of Bubble formation cycle count is surpassed the 5th time period (being about 1 minute to 2 minutes).As definite result, if the 5th time period (for about 1 minute to 2 minutes) does not expire, control module 72 is proceeded the Bubble formation circulation, until the 5th time period expired.

When the 5th time period expired, control module 72 was determined at the cylinder 12 a large amount of bubbles of inner generation and is finished the Bubble formation circulation.
