Problems solved by technology

[0005] However, when the stirring mechanism and the motor that drives the stirring mechanism rotate are abnormal, if it is not found in time, the water that has not been successfully processed is easily returned to the washing bucket, causing pollution to the clothes in the washing bucket.
At the same time, the flocculation efficiency will be greatly affected when the stirring mechanism works at different speeds and turn-to-stop ratios.

Embodiment 1

[0047] In this embodiment, the set value Vi is a set range from V1 to V2; when the detected value V is less than the set value V1, increase the input power of the motor until the detected value V reaches (V1+V2) / 2 ; When the detected value V is greater than the set value V2, reduce the input power of the motor until the detected value V reaches (V1+V2) / 2. Preferably, V2-V1=10rpm, so as to make the setting range reasonable, improve the control precision and reduce the misjudgment rate.

[0048] By setting the setting value as a range interval, a buffer space is provided for the adjustment of the motor, and on the premise of ensuring the accuracy of the speed control, it is avoided that the motor adjusts the frequency too fast and reduces the service life.

[0049] In this embodiment, when the washing machine starts to perform the flocculation process and the agitation mechanism starts to rotate, the input power W of the motor is the maximum value Wmax, so that the rotation spee...

Embodiment 2

[0063] This embodiment introduces a flocculation control method of a flocculation washing machine. In different time periods of the flocculation process, corresponding to different set values ​​Vi, to change the input power W of the motor, so that the stirring mechanism can V rotates. In this embodiment, during the flocculation process of the washing machine, the motor is controlled to work at the corresponding speed V according to the driving method described in the above embodiment, so as to change the speed of the stirring mechanism during the flocculation process and achieve the purpose of precise control of the flocculation process.

[0064] In this embodiment, in the flocculation process of the washing machine, according to the existing sequence of time periods, different corresponding motor speed setting values ​​Vi are correspondingly matched, so as to realize that the stirring mechanism operates at different speeds in different time periods during the flocculation proc...

Embodiment 3

[0070] This embodiment introduces a stirring mechanism of a flocculation washing machine. The washing machine includes a flocculation bucket 1 for flocculation treatment of washing water; Flocculate the water in bucket 1.

[0071] Such as figure 2 with 3 As shown, in this embodiment, the stirring mechanism in the flocculation bucket 1 includes a stirrer driven by the motor 6 to rotate; the stirrer includes a rotating shaft 10, and the rotating shaft 10 is connected with a plurality of stirring blades rotating around the rotating shaft 10 5. The rotating shaft 10 is provided with a pulley 8, which is connected to the output end of the motor 6 through the belt 7, so that the motor 6 is driven by the belt to drive the stirring blade 5 to rotate around the rotating shaft 10.

[0072] In this embodiment, the motor 6 is fixedly installed on the outside of the side wall of the flocculation bucket 1, and the motor 6 is set beyond the liquid level of the flocculation bucket 1. The m...

Abstract

The invention relates to a drying method of a stirring motor in the flocculation treatment process. When the washing machine executes a flocculation program, the motor drives the stirring mechanism to work, and a stirring mechanism rotating speed V is detected; when a detection value V is smaller than a set value Vi, the motor is adjusted to increase the stirring mechanism rotating speed; when the detection value V is smaller than the set value Vi, the motor is adjusted to reduce the stirring mechanism rotating speed. Through the control method, input power and the like of the motor can be subjected to controllable adjustment so as to achieve precise control over the stirring mechanism rotating speed and the purpose of improving flocculation reaction efficiency. The invention further relates to a flocculation washing machine applied to stirring motor driving method. The flocculation washing machine achieves precise control over the flocculation process and precise judgment of the flocculation washing machine fault so as to avoid backflow conditions of sub-standard flocculation water from generating. Meanwhile, the flocculation washing machine is simple in structure, the method is brief, the effect is remarkable, and the flocculation washing machine is suitable for application and popularization.

Description

technical field [0001] The invention relates to a washing machine in the field of washing machines, which adopts a flocculation method to perform self-cleaning treatment on water, in particular to a motor driving method for a stirring mechanism in the flocculation treatment process, and also relates to a washing machine equipped with a stirring mechanism and applying the above method to agitate Mechanism for driving the washing machine. Background technique [0002] With the improvement of people's living standards, the washing machine has become one of the main household appliances in people's daily life. The washing process of the washing machine mainly includes several stages of washing, rinsing and drying. After entering the rinsing stage, in order to rinse off the stains and residual detergent, it is necessary to enter more water or perform more rinsing times to rinse the clothes, which will consume a lot of water resources, even if it is a water-saving drum washing mac...
