Structure below with reference to the existing tumbling-box washing machine of Fig. 1 schematic illustration.
Fig. 1 is the skiagraph of existing tumbling-box washing machine one example.Wherein, casing (5) inboard is provided with steel ladle (3), and the inboard of steel ladle (3) is provided with cylinder (9).
Be provided with the rotating shaft (13) that is used for the driving force of motor (6) is delivered to cylinder (9) in the cylinder (9).
Simultaneously, the front and back of rotating shaft (13) respectively are provided with bearing (12), and the central authorities of the rear wall parts of steel ladle (3) then are provided with the bearing block that is used to support above-mentioned bearing (12).
The rear portion of steel ladle (3) directly is linked with the stator (7) that constitutes motor (6), then is combined with the rotor (8) that together constitutes motor (6) with stator (7) in the rotating shaft (13).
Thus, cylinder (9) directly connects rotor (8) and rotates.
In addition, the place ahead of casing (5) is provided with hatch door (1), then is provided with pad (2) between hatch door (1) and the steel ladle (3).
And, be provided with the lifting spring (4) that is used to support steel ladle (3) on the inboard of casing (5) between the upper outside face of end face and steel ladle (3).Be provided with between the outside bottom surface of the inboard bottom surface of said machine casing (5) and steel ladle (3) and produce the damper (10) of vibrations when being used to reduce steel ladle (3) dehydration.
In addition, a side of motor (6) is provided for the electromechanical transducer (11) of detection rotor (8) rotation number.
As above in the existing tumbling-box washing machine of structure, in washings is rendered to cylinder (9) after, selected required laundry pattern and when driving washing machine, washings supply in the cylinder (9), begin rotation and carry out washing process with back roll (9).
After finishing washing process, washings are to the outside discharge and carry out rinse cycle.Then, motor (6) beginning is rotation at a high speed, and the washings that attaches on will the madial wall to cylinder (9) by the centrifugal force that produces dewaters.
After finishing, rinse cycle then carries out dehydration.
Fig. 2 is the flow chart of prior art intermediate roll formula laundry machine dehydration process.
Dehydration is divided into the main water smoking of cylinder (9) with the high speed rotation of water smoking at initial stage of rotor (8) low speed rotation and cylinder (9).
In when dehydration at initial stage, consider unbalance problem and carry out the washings amount and detect (S201), to satisfy the unbalance condition that is suitable for drive system.
The method that above-mentioned washings amount detects reaches certain speed (about 70 rev/mins) the required time by cylinder (9) and judges.
Because the washings amount reaches the time (t) of certain speed when increasing also increase thereupon, judge the washings amount so can reach the required time of certain speed by cylinder (9).
For the inner washings of cylinder (9) is evenly disperseed, (about+as 1/100ms) slowly to quicken cylinder (9) (S202) with certain acceleration.
The balance of washings is to finish when cylinder (9) quickens because cylinder (9) inside does not have remaining washings, when rotary speed near 108 rev/mins, washings will be attached on the madial wall of cylinder (9).
When the rotary speed of cylinder (9) arrives 108 rev/mins, according to the variable quantity detection eccentric mass (S203) of rotary speed.
At this moment, if the dispersion of washings is better in the above-mentioned equilibrium process, washings is evenly spread under the situation of cylinder (9) inwall, swing roller (9) makes on the motor (6) and is added with certain load mutually; If the dispersion of washings is relatively poor in the above-mentioned equilibrium process, make washings not evenly spread to cylinder (9) inwall and be inclined under the situation of a side or entanglement, the load of addition was bigger when cylinder was raised tendency one side of washings or entanglement part, and then the load of addition is less when falling washings and be inclined to a side or entanglement part on the contrary.
Therefore, the magnitude of load that is added on the motor (6) when disperseing when washings is eccentric is indefinite, and the rotation that causes cylinder (9) is unstable and rock.In the control part of control motor rotation, when the rotary speed of motor changes in setting range, be judged as eccentric mass in tolerance band; When the rotary speed of motor changes beyond setting range, then be judged as eccentric mass greater than tolerance band (S204).
Here, when the washings eccentric mass that is judged as detection below institute's qualification motor rotary speed (example: about 108 rev/mins) satisfies tolerance band, end initial stage dehydration and the interim rotation number that promotes rotor (8) are led dehydration (S205) rising under the state of maximal rate.
On the contrary, when being judged as the washings eccentric mass that below the qualification rotation number, detects when exceeding tolerance band, motor (6) is stopped a period of time after (S206), turn back to above-mentioned steps S202 and cylinder is quickened with certain acceleration.
At this moment, above-mentioned acceleration is got certain value, and irrelevant with the washings amount.
But the dehydration controlling method of existing tumbling-box washing machine has following problem:
In the equilibrium process of prior art, no matter washings what and with certain acceleration cylinder (9) is quickened.
Like this, no matter washings what and adopt identical acceleration to quicken cylinder, it is also just different that its washings disperses, and makes the dispersion of washings relatively poor.
Thus, when the dispersion of washings is relatively poor master's water smoking enter difficulty, main water smoking entry time is lengthening immediately also, also can cause the vibrations of steel ladle (3) bigger even if dewater.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide the washings good dispersion to make the dehydration controlling method of the tumbling-box washing machine that the dehydration entry time shortens, steel ladle shakes when reducing dehydration simultaneously.
The dehydration controlling method of tumbling-box washing machine involved in the present invention accelerates to cylinder in the process that washings adheres to speed for detecting the degree of eccentricity, controls the size of acceleration according to the washings amount in the cylinder.
Wherein, it is ideal that the size of above-mentioned acceleration can make the washings dispersion effect of corresponding washings amount.
The dehydration controlling method of related tumbling-box washing machine is divided into following several stages among the present invention: in the 1st stage, detect the washings amount; In the 2nd stage, the acceleration of determining according to the washings amount quickens cylinder; In the 3rd stage, detect the cylinder eccentric mass that adheres to the speed rotation by washings; In the 4th stage, when eccentric mass rotates at a high speed during less than a reference value and dewaters, after then stopping certain hour with motor during greater than a reference value, eccentric mass turned back to for the 2nd stage.
Wherein, the size of acceleration is the ideal accekeration of washings dispersion effect that can make corresponding washings amount in above-mentioned the 2nd stage.
After turning back to above-mentioned the 2nd stage, the acceleration magnitude at the size of acceleration and the 2nd initial stage in stage is different.
As mentioned above, the dehydration controlling method of tumbling-box washing machine involved in the present invention when quickening for the dispersion of washings, is selected best acceleration for use according to the washings amount, makes it reach washings and disperses optimization.
The good dispersion of washings has shortened the dehydration entry time, the vibrations of steel ladle when having reduced dehydration simultaneously.
Content by above-mentioned explanation as can be known, person skilled can be carried out multiple different distortion and correction in the scope that does not exceed the technology of the present invention thought.When will describing example in detail in conjunction with the drawings, other purpose of the present invention, feature and advantage further introduce.

The specific embodiment
Specific embodiments of the invention are described with reference to the accompanying drawings.
Fig. 3 is the precedence diagram of the dehydration of intermediate roll formula washing machine of the present invention, and Fig. 4 is the drum rotation speed chart during for intermediate roll formula laundry machine dehydration of the present invention.
In the washing process of tumbling-box washing machine, at first washings is rendered in the cylinder (9), selected required washing mode also drives washing machine, and washings are supplied in the cylinder (9), begins the left and right directions rotation and carries out washing process by motor (6) head roll (9).
Washings are discharged to the outside after washing process finishes, and washings are re-supplied in the cylinder (9), and then cylinder (9) begins rotation and carries out rinse cycle.After being over, rinse cycle then carries out cylinder (9) the washings dehydration of rotation at a high speed.
Dehydration is divided into the initial stage water smoking of cylinder (9) along with rotor (8) low speed rotation, and rotates the main water smoking of realizing main dehydrating function at a high speed.
In when dehydration at initial stage, consider unbalance problem and carry out the washings amount and detect (S301), to satisfy the unbalance condition that is suitable for drive system.
The method that above-mentioned washings amount detects reaches certain speed (about 70 rev/mins) the required time by cylinder (9) and judges.
Because the washings amount reaches the time (t) of above-mentioned certain speed when increasing also increase immediately, judge the washings amount so can reach the required time of certain speed by cylinder (9).
For the inner washings of cylinder (9) is evenly disperseed, cylinder (9) is slowly accelerated to washings attached to adhering to speed (S302) on the inner wall of rotary drum according to the acceleration of the washings amount decision of above-mentioned detection.
The balance of washings is to finish when cylinder (9) quickens, and the acceleration magnitude with maximum washings dispersion effect is difference with the difference of washings amount.
For this reason, use the different best accekeration of corresponding different washings amounts respectively among the present invention, thereby improved the efficient that washings disperses.
Below table 1 list according to the difference of washings amount and different accekerations.
Table 1
| The washings amount | Acceleration |
| In a small amount below 70 | 1/160ms, 1/190ms are alternately |
| Amount 70-80 in little | ??1/150ms |
| Middle amount 80-90 | ??1/180ms |
| A large amount of more than 90 | ??1/200ms |
Hence one can see that, when for the balance of washings cylinder (9) being quickened, according to the different acceleration of how much selecting of washings amount, thereby the washings dispersion effect maximized.
Wherein, when the washings amount is a small amount of situation below 70, be used alternatingly the acceleration of two kinds of different sizes of 1/160ms, 1/190ms.
That is, as shown in Figure 4, when the washings of same thing amount is used alternatingly different acceleration, can further improve the dispersion effect of washings.
When the rotary speed of cylinder (9) arrives 108 rev/mins, detect eccentric mass (S303) according to the change in rotational speed amount.
At this moment,, washings is evenly spread under the situation of cylinder (9) inwall, be added with certain load mutually on the motor (6) during swing roller (9) if the dispersion of washings is better in the above-mentioned equilibrium process; If the dispersion of washings is relatively poor in the above-mentioned equilibrium process, make washings not evenly spread to cylinder (9) inwall and be inclined under the situation of a side and entanglement, the load of addition is bigger when raising tendency one side or entanglement part with the winding drum hoist structure, and then the load of addition is less when falling tendency one side or entanglement part on the contrary.
Therefore, the magnitude of load that is added on the motor (6) when washings is eccentric is indefinite, and the rotation that causes cylinder (9) is unstable and rock.In the control part of control motor rotation, when the rotary speed of motor changes in setting range, be judged as eccentric mass in tolerance band; When the rotary speed of motor changes beyond setting range, then be judged as eccentric mass greater than tolerance band (S304).
Here, setting below the rotation revolution when being judged as, when the eccentric mass of the washings of detection exceeds tolerance band, motor (6) stopped a period of time after, turn back to above-mentioned steps S302 and cylinder (9) slowly quickened by the acceleration of washings amount decision.
On the contrary, when being judged as below above-mentioned setting rotation revolution, when the eccentric mass of the washings of detection satisfied tolerance band, dehydration of end initial stage and the interim rotation number that promotes rotor (8) were led dehydration (S305) rising under the state of maximal rate.
Therefore, in above-mentioned equilibrium process, determine the size of acceleration by the washings amount, make the washings dispersion effect reach maximization, thereby reduced owing to eccentric mass exceeds the number of times that tolerance band turns back to step S302, make that to enter main dehydration easy, shortened the entry time of main dehydration simultaneously.
Finished the dehydration process of intermediate roll formula washing machine of the present invention by above-mentioned steps.
