Problems solved by technology

This method has gradually exposed its shortcomings after long-term use: the number of unbalanced times needs to be recalculated every time it is rinsed, that is to say, the unbalanced alarm will be issued after accumulating 3 times in a single rinsing and dehydration. If the washing machine Due to the reasons of the balance system such as the boom or other reasons, in a standard program with a second rinse, there may be 6 unbalance corrections, and some unbalanced states do not necessarily need to be corrected by refilling the water. eliminate
However, such an unscientific unbalanced correction program method may consume 6 buckets of washing water, waste a lot of water resources, consume electricity, and correspondingly prolong the entire washing time
[0003] The Chinese invention patent with the application number of 200310105668.4 discloses a method for the washing process of a fully automatic washing machine. The number of unbalanced times is accumulated in the whole process of the washing process. When the total process of the washing process accumulates 3 times and the barrel is unbalanced, the alarm will be issued. Using the accumulated unbalanced times and taking the entire washing process of the washing machine as the basis for the accumulated alarm, although unnecessary correction times have been reduced and water consumption has been saved to a certain extent, the effect of correcting the unbalance is poor and often occurs. alarm phenomenon

Embodiment 1

[0035] The dehydration unbalance correction process of the washing machine in this embodiment: add one water storage correction after 3 times of water storage correction, and alarm after 3 dehydration still occurs after 3 times of dehydration.

[0036] details as follows:

[0037] When the drum is unbalanced during the first dehydration, the safety switch is disconnected and the drum stops;

[0038] Use 0.8 times the motor startup acceleration during the first dehydration as the motor startup acceleration for the second dehydration. If the barrel is unbalanced, the safety switch is turned off and the barrel stops;

[0039] Use 0.8 times of the motor start-up acceleration during the second dehydration as the motor start-up acceleration for the third dehydration. If the barrel is unbalanced, the safety switch is turned off, and the first water storage correction is performed. After the brakes, the water is filled to the original setting. Water level, after washing with balanced...

Embodiment 2

[0043] The dehydration unbalance correction process of the washing machine in this embodiment: add a water storage correction after 3 times of water storage and correction, and an alarm will be given if the 2 times of dehydration still occur after the 2 times of water storage correction, and the others are the same as in the first embodiment.

[0044] If present embodiment reports to the police, then takes place 8 times of dehydration, 2 times of water storage correction.

Embodiment 3

[0046] The difference between this embodiment and the above-mentioned embodiment 1 and embodiment 2 is that the starting acceleration of the motor is changed during dehydration, and 0.8 times of the starting acceleration of the motor during the first dehydration is used as the starting acceleration of the motor for the second dehydration. The barrel is unbalanced, the safety switch is disconnected, and the barrel stops;

[0047] Use 0.6 times of the motor start-up acceleration during the second dehydration as the motor start-up acceleration for the third dehydration. If the barrel is unbalanced, the safety switch is turned off, and the first water storage correction is performed;

[0048]The change mode of the motor starting acceleration during dehydration before the second water storage correction is as follows: the motor starting acceleration during the first dehydration is used as the motor starting acceleration for the second dehydration. stop;

[0049] Use 0.8 times of t...

Abstract

The invention discloses a dewatering unbalance correction method for washing machine. In the dewatering process, a water storage correction operation is performed after dewatering barrel-impact unbalance occurs for N times, and if barrel-impact unbalance still occurs after water storage correction for M times and dewatering for N1 times, an alarm is given, wherein N is more than or equal to 2, M is more than or equal to 2, and N is more than or equal to N1 more than or equal to 1. The invention adopts water storage correction at time intervals, dewatering start-up times is accumulated in each time interval, and dewatering start-up times is calculated after water storage correction times is achieved, so as to give an alarm. In such a way, dewatering start-up times is increased, water storage correction probability is greatly reduced, water used in unbalance correction is saved, and washing time delayed by unbalance correction is shortened.

Description

technical field [0001] The invention relates to a washing machine dehydration method, in particular to an imbalance correction method capable of saving water during the washing machine dehydration process. Background technique [0002] The execution process of the existing standard program of a fully automatic washing machine is as follows: start-water intake to the set water level-washing-drainage-intermittent dehydration-continuous dehydration-inertia dehydration-water intake to the set water level-rinsing 1-drainage-intermittent dehydration- Continuous dehydration-inertial dehydration-water intake to set water level-rinsing 2-drainage-intermittent dehydration-final continuous dehydration-inertial dehydration-end. The above laundry procedures are defined as standard washing. The washing machine using the above laundry procedure method has unbalance correction. The specific method is to detect the unbalance switch of the washing machine during dehydration. The unbalance sw...
