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=mgcos 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.
Can realize the attaching of washings 21 till being carved near the drum rotation speed shown in the circular Reference numeral 2 during from stopping shown in the circular Reference numeral 1 of Fig. 7 and being about 50rpm reliably.In addition, the anglec of rotation θ of the swing roller 24 that the attaching of washings 21 is required satisfies the condition of having stated less than 90 degree.
In addition, washings 21 is attached on the swing roller 24 and with its cylinder anglec of rotation of lifting for greater than 90 degree and less than 180 degree, but in the example of Fig. 7, near 125 degree of the cylinder anglec of rotation shown in circular Reference numeral 2.Being recited as the heavy line of " attaching degree " and the solid line of swing roller 24 rotations intersects near this cylinder anglec of rotation 125.When the cylinder anglec of rotation was neighbouring greater than 125 degree, the solid line of swing roller 24 rotations was positioned at the downside of the heavy line that is recited as " attaching degree ".Therefore, by near the braking that stops spending near the cylinder anglec of rotation 140 that reaches circular Reference numeral 3 the cylinder anglec of rotation 125 degree as can be known, the maximum (top) speed of the inner surface of washings 21 spinning cylinders 24 being peeled off because of the deadweight that acts on rotatory inertia on the washings 21 and washings 21 gets final product for being decelerated to 45rpm a little.
According to aforementioned calculation and experience as can be known, the maximum rotative speed of arc rotating is more than 40rpm under positive and negative arc rotating drive pattern, by the braking of carrying out with maximum rotative speed washings 21 is peeled off, can obtain the effect of positive and negative arc rotating drive pattern.In addition, peel off under the positive and negative arc rotating drive pattern washings 21 can be as illustrated in fig. 7 by being that brakings in the scopes of 125 degree～140 degree are carried out in the cylinder anglec of rotation.Particularly, when with the drum rotation speed being the arc rotating deceleration of carrying out more than the 40rpm, because desire continues rotatory inertia and deadweight with the washings 21 that is rotated more than the 40rpm, washings 21 is applied and to the corresponding pressure peeling force of deceleration of slowing down less than 40rpm it fallen.
And, shown in Fig. 6 B under the positive and negative arc rotating drive pattern, initial camber line carries out near being rotated in 140 degree, the later arc rotating of Fig. 6 B shown in Fig. 6 C～Fig. 6 F shown in solid line among Fig. 7 near the cylinder anglec of rotation is 140 degree～carry out near 30 the scopes spending.And, when initial arc rotating, by the cylinder anglec of rotation is the top of the initial arc rotating side about near the arc rotating 120 degree will be still in swing roller 24 bottoms shown in dotted line among solid line, Fig. 6 B among Fig. 6 A washings 21 is lifted to, and brakes between 120 degree～140 degree.As a result, can make washings 21 fall the roughly bottom of swing roller 24.Washings 21 falls later arc rotating, will lift on the position on top, the same side (for example 150 spend) of swing roller 24 near a side about swing roller 24 (for example 30 degree) washings 21 that falls.The action that can obtain to make the left and right sides opposition side of falling swing roller 24 is symmetry and fall distance for the maximum of the diameter amount of swing roller 24 roughly.Thus, can improve the effect that tangling of washings 21 untied and beaten.
As shown in Figure 4, when carrying out the stirring 2 of the 2nd whipping process, do not confirm whether to have supplied water predetermined water level by water level detecting portion 39.Whether the mixing time of confirming stirring 2 in step 116 has reached stipulated time S2 (for example 8 seconds), continues to stir 2 if then do not turn back to step 115 through stipulated time S2.Under the situation of having passed through stipulated time S2, be transferred to step 117.Judge in step 117 whether wash time has passed through stipulated time T1, under the situation of having passed through stipulated time T1, in step 118, finish washing process, in control part 44, stop the driving of motor 28, make the stirring rotation of swing roller 24 stop the rinse cycle after transferring to.If then not turning back to step 109 through stipulated time T1, wash time carries out the 1st whipping process.
As mentioned above, the washing process alternate repetition carries out the 1st whipping process and the 2nd whipping process.At this, in the 1st whipping process, the rotary speed of the action that falls with expression upborne washings 21 is dominant from its deadweight by the rotation of swing roller 24 height makes swing roller 24 just change repeatedly, stop, reversing, stop continuously; In the 2nd whipping process, positive and negative alternate ground carries out following action repeatedly: make swing roller 24 carry out arc rotating rapidly, the anglec of rotation that the centrifugal force that utilization produces because of the arc rotating rapidly of swing roller 24 is attached on swing roller 24 inner surfaces washings 21 the lower position of washings 21 spinning cylinders 24 is lifted to swing roller 24 is greater than 90 degree and less than the positions of 180 degree, then by the rotation of brake motor 28 rapidly, when washings 21 is peeled off because of its inertia and deadweight spinning cylinder 24 inner surfaces to swing roller 24 bottoms with lift the heterochiral side of side and fall.
And the fluctuation of water table in whipping process avoids carrying out the detection of water level than in the 1st whipping process the 2nd whipping process big, that the water level detecting deviation is bigger.As a result,, therefore, the deviation that makes water consumption of tumbling-box washing machine be can reduce, cleaning, rinsing function-stableization made owing to can utilize water level detecting portion 39 to detect the necessary predetermined water level of washing.
Fig. 8 A, 8B are the major part action flow charts of the tumbling-box washing machine of embodiment of the present invention 2.The longitudinal section of the tumbling-box washing machine of embodiment of the present invention 2, module control circuit figure, input configuration part and display part are identical with the tumbling-box washing machine of embodiment of the present invention 1, therefore to the identical same Reference numeral of structural detail mark, omit its explanation.
Shown in Fig. 8 A, Fig. 8 B, in the 1st whipping process of the tumbling-box washing machine of embodiment of the present invention 2, do not reach in wash time under the situation of stipulated time T1, the water level of always additional washings 50 with tank 26 remains the control of water level.That is, in the 1st whipping process, the 1st predetermined water level W1, the 2nd predetermined water level W2, the 3rd predetermined water level W3 are set, after water level detecting portion 39 detects the water level of the 2nd predetermined water level W2 or the washings 50 more than the 3rd predetermined water level W3, carry out the 2nd whipping process.
More specifically, in the step 114 of the 1st whipping process, wash time is not passed through under the situation of stipulated time T1 (for example 25 minutes), is transferred to step 115, confirms whether to have reached washing necessary the 2nd predetermined water level W2 (for example 60mm).Under the situation that does not reach the 2nd predetermined water level W2, in step 116, supply water.Under the situation that has reached predetermined water level W2, be transferred to step 118.
After in step 116, supplying water, in step 117, judge whether to have reached the 3rd predetermined water level W3 (for example 80mm).Under the situation that reaches the 3rd predetermined water level W3, be transferred to step 118 and be transferred to the 2nd whipping process and stir 2.Under the situation that does not reach the 3rd predetermined water level W3, turn back to step 116 and supply water.
