In step 107, make feed water valve 37 work and supply water, in step 108, utilize the 1st predetermined water level W1 (for example 60mm) that judges whether to supply water of water level detecting portion 39.Under the situation that is judged as the 1st predetermined water level W1 that supplies water, in step 109, enter the 1st whipping process, drive motor 28, the stirring rotation of beginning swing roller 24 and stir 1 (for example repeat to turn round 15 seconds, stop 3 seconds, the just commentaries on classics counter-rotating of rotational speed N=45rpm).
Stirring in 1, driving swing roller 24 rotations with rotational speed N (for example 45rpm), dropping on the water surface after the washings 21 in the swing roller 24 are lifted by lobe plate 29, on other clothings or swing roller 24 inner bottom parts, wash by motor 28.In addition, under the situation of the 1st predetermined water level W1 that do not supply water, turn back to step 107.Judge in step 110 whether water level has reached the 2nd predetermined water level W2 (for example 60mm),, then be transferred to step 113 if reach the 2nd predetermined water level W2.If do not reach the 2nd predetermined water level W2, then be transferred to step 111 and supply water, in step 112, judge whether to reach washing necessary the 3rd predetermined water level W3 (for example 80mm).
If reach the 3rd predetermined water level W3, then be transferred to step 113.If do not reach the 3rd predetermined water level W3, then return step 111 and supply water.Like this, in washing process, supply comprises promptly that owing to washings 21 absorbs the water in shortage that moisture causes water level to reduce drawdown supplies water interiorly to washing necessary the 3rd predetermined water level W3.
Whether the mixing time of confirming stirring 1 in step 113 has reached stipulated time S1 (for example 54 seconds), does not then turn back to step 109 continuation stirring 1 if reach.Under the situation that has reached stipulated time S1, be transferred to step 114, confirm whether wash time has passed through stipulated time T1 (for example 25 minutes).Under the situation of having passed through stipulated time T1, be transferred to step 118 and stop the driving of motor 28, swing roller 24 is stopped and finishing washing process, the rinse cycle after entering into.If reach stipulated time T1 and then in step 115, be not transferred to the 2nd whipping process, the drive motor 28 and stirring of beginning swing roller 24 stirs 2.
At this, the stirring 2 of the 2nd whipping process is described.
Stir 2 and carry out such arc rotating drive pattern, that is, the anglec of rotation that is rotated cylinder 24 is greater than 90 degree and less than 180 arc rotating rapidly (arc rotating rapidly) and the brakings rapidly of spending.Adopt the arc rotating drive pattern, the anglec of rotation by swing roller 24 can be lifted to washings 21 to greatest extent greater than 90 degree and less than 180 degree greater than 90 degree and less than the arc rotating rapidly of 180 degree and braking rapidly.In addition, the arc rotating drive pattern can produce on-position by the braking rapidly at the terminal hour that lifts washings 21, thereby washings 21 is peeled off because of the inner surface of its inertia and deadweight spinning cylinder 24 and fall because of its deadweight.Therefore,, can apply mechanical force, therefore can improve cleaning function washings 21 preventing to have improved the effect of untiing of tangling when washings 21 tangles mutually.
In addition, positive and negative arc rotating drive pattern is positive rapidly arc rotating of forward and the reverse pattern of anti-arc rotating rapidly that alternately repeats the arc rotating drive pattern.Arc rotating rapidly by positive and negative alternate drives, and alternately changes cocked position, the lowering position of washings 21 about can be in each arc rotating drives.Therefore, can tangle the effect of untiing preventing from further to improve when washings 21 tangles mutually, and can increase the number of times that washings 21 is applied mechanical force, therefore can improve cleaning function.
Next, use the action of the washings 21 in Fig. 6 A~Fig. 6 G explanation arc rotating drive pattern and the positive and negative arc rotating drive pattern.Fig. 6 A~Fig. 6 F is the process schematic diagram of positive and negative arc rotating drive pattern of the tumbling-box washing machine of embodiment of the present invention 1, and Fig. 6 G is the schematic diagram that is illustrated in the explanation usefulness of the cocked position of washings under the positive and negative arc rotating drive pattern of this tumbling-box washing machine and lowering position left-right reversed.In addition, this Fig. 6 A~Fig. 6 G is the schematic diagram that is used to illustrate the action of actual washings 21, does not limit the content that claims are put down in writing.
Above-mentioned swing roller 24 is by lifting to washings 21 to greatest extent greater than 90 degree and less than 180 degree to solid line position from Fig. 6 B, Fig. 6 D, the illustrative dotted line position of Fig. 6 F greater than 90 degree and less than the arc rotating of 180 degree.In addition, by the sequence alternate according to Fig. 6 B, Fig. 6 D, Fig. 6 F, Fig. 6 D, Fig. 6 F... carry out this rapidly arc rotating drive and to form positive rapidly arc rotating and drive and the driving of anti-rapidly arc rotating.Shown in Fig. 6 C, Fig. 6 E, lifting the terminal hour of washings 21, produce the on-position that is used to reverse, washings 21 is peeled off because of its inertia and the inner surface of spinning cylinder 24 of conducting oneself with dignity reliably.Then, utilize the deadweight of washings 21, can make washings 21 draw out as from dotted line position to the parabola ground shown in the arrow of solid line position to lift the heterochiral side of side and fall.
And, arc rotating rapidly by positive and negative alternate drives, the cocked position, lowering position that can make washings 21 in arc rotating drives rapidly at every turn shown in Fig. 6 G about alternately transposing, therefore can not only improve tangling the effect of untiing but also washings 21 being applied mechanical force of washings 21.
That is, the arc rotating rapidly of positive and negative alternate of carrying out washings 21 is lifted to the one-sided top, the left and right sides of swing roller 24 by the arc rotating of swing roller 24 drives, and produces in the final moment of lifting washings 21 or near it to slow down or the state of braking.Then, force to peel off because of its inertia and deadweight and because of the arc rotating rapidly of its deadweight positive and negative rotation of falling of opposition side to the left and right drives by repeated washing thing 21, alternately change cocked position, the lowering position of washings 21 about can be when each arc rotating.The result, can improve the effect of untiing of tangling of washings 21, prevent tangling mutually certainly needless to say of washings 21, can also prevent that the reversing of washings 21, washings 21 are attached on the inner surface of swing roller 24, can easily take out washings 21 and alleviate significantly on the washings 21 to produce fold.And, can apply mechanical force to washings 21.Owing to can increase considerably the drop number of washings 21, therefore can effectively utilize and realize to beat clean result, beat wash effect, stretch the function of tumbling-box washing machine in each process such as open fold effect by what beat generation by what the effect of beating produced.
In addition, the arc rotating of the positive and negative alternate of swing roller 24 drive washings 21 arrive from the lower position of swing roller 24 anglec of rotation be near 90 degree before so that the anxious acceleration that washings 21 is attached on the inner surface of swing roller 24 carry out.Though the lower position of washings 21 spinning cylinders 24 is picked up, they can not be with swing roller 24 rotations, and are easy to fall because of deadweight near the anglec of rotation is 90 degree.
At this, the arc rotating rapidly of the positive and negative alternate of anxious acceleration drives washings 21 applied with the corresponding inertia of the rotary speed of swing roller 24 it is lifted reliably, makes washings 21 be attached to that the cocked position up to regulation can not slide on the inner surface of swing roller 24.As a result, can realize more reliably because of cocked position from the washings 21 that inertia constantly and deadweight peel off to on-position that change left-right reversed with the lowering position of the washings 21 that falls to a side opposite because of the deadweight of washings 21 with lifting side.
In addition, the positive and negative arc rotating that switches in swing roller 24 of the arc rotating direction of swing roller 24 is carried out greater than 90 degree and less than the braking maneuver that adds rapidly under the condition of 180 degree.The result, under the anxious acceleration that makes washings 21 take place to adhere to, the arc rotating direction is reversed positive and negatively rapidly, at the terminal hour of arc rotating, the deadweight of inertia during because of anxious acceleration and washings 21 is peeled off washings 21 reliably and it is fallen to a side opposite with lifting side, thereby can suppress washings 21 is applied the loss of mechanical force.Thereby, can in the shorter time, utilize the function of each process of tumbling-box washing machine, prevent tangling mutually, reversing of washings 21, alleviate the generation of fold.
Observe the action of above-mentioned washings 21 and find that the positive and negative arc rotating drive pattern of the tumbling-box washing machine of embodiment of the present invention 1 can be considered as follows.Promptly, repeat such driving positive and negative arc rotating drive pattern positive and negative alternate, promptly, the centrifugal force that utilization produces because of the arc rotating rapidly of swing roller 24 is attached on the inner surface of swing roller 24 washings 21 and lifts to after the top, brake swing roller 24 rapidly, this upborne washings 21 is peeled off from the inner surface of swing roller 24 because of its inertia, and the driving that falls because of its deadweight.
In addition, positive and negative arc rotating drive pattern is repeated below the pattern of driving with can understanding into positive and negative alternate, that is, the centrifugal force that utilizes the arc rotating rapidly because of swing roller 24 to produce is attached on the inner surface of swing roller 24 washings 21 to lift to the top of swing roller 24.Then, brake swing roller 24 rapidly, washings 21 is peeled off because of the inner surface of its inertia spinning cylinder 24, and the side opposite with lifting side to swing roller 24 bottoms falls because of its inertia and deadweight.
At this, the positive arc rotating of swing roller 24 and anti-arc rotating are adapted at carrying out the best less than carrying out repeatedly under 180 conditions of spending under the conditions greater than 90 degree.
At this, be in the swing roller 24 of 500 ± 50mm at diameter, the gravity that puts on the washings 21 is decomposed along the center position and the tangential direction of swing roller 24, by mr ω 2=m gcos θ (m: the quality of washings 21, r: the center of spinning cylinder 24 is to the distance of washings 21, ω: the angular speed of swing roller 24, g: acceleration of gravity, θ: the anglec of rotation) calculate the drum rotation speed of the power and the centrifugal force balance of center position, the result as shown in Figure 7.Fig. 7 be used for realizing idealizedly embodiment of the present invention 1 tumbling-box washing machine positive and negative arc rotating drive pattern, peel off corresponding revolving property figure from this inner surface with washings is attached on the swing roller inner surface and with washings.
