Description
Technical field
The present invention relates to washing machine technology field, be specifically related to a kind of laundry machine dehydration control system and method.
Background technology
Washing machine is appliances indispensable in Modern Family's life, no matter it adopts is common electric machine or variable-frequency motor, the dewatering time of washing machine is all program Solidification.But the material of dewatering time needed for clothing reality and clothing has much relations, the clothes dewatering efficiency of different loads, unlike material, different initial aqueous rate is not identical yet.If dewatering time is long, not only causes the waste of water resource and electric resources, also have damage to clothing; If dewatering time is too short, then clothing is de-does not do, and dehydrating effect is bad.
In order to improve the dehydrating effect of washing machine, improve the dewatering efficiency of washing machine, existing dewatering control method for washing machine, is generally the offset situation first being judged machine barrel by eccentricity detecting, then formulates different dehydrating speeds according to eccentric situation.
As, application number be 201510375762.4 Chinese patent application file disclose a kind of eccentric detection method of roller washing machine, wherein, roller washing machine comprises series excited machine, this eccentric detection method comprises the following steps: after detecting that dehydration procedure starts, and controls series excited machine and starts; Control series excited machine raising speed to the first preset rotation speed, and maintain the first Preset Time in the first preset rotation speed, and calculate the undulating value of series excited machine rotating speed in the first Preset Time; Series excited machine nature reduction of speed to the second preset rotation speed, and detect the deceleration time of series excited machine from the first preset rotation speed reduction of speed to the second preset rotation speed, the second preset rotation speed is less than the first preset rotation speed; And obtain eccentricity value according to undulating value and deceleration time.Adopt above-mentioned eccentric detection method can carry out eccentricity detecting more accurately to washing machine, improve the stationarity of roller washing machine.
But in actual application, when the physical hardwares such as the complete machine structure part of washing machine and shock mitigation system do not make change, when the load load-bearing of machine barrel is different, offset can produce impact in various degree to the vibrations of complete machine, noise, safety and life-span.Based on different load weights, offset is different on the impact of dehydrating effect, and when load is less, complete machine institute's eccentric value that bears when high speed dewatering is less; When load is larger, the eccentric value that complete machine can bear when high speed dewatering is larger.But because clothing is in dehydration, the load moisture content of clothing constantly diminishes, the offset of washing machine reality and load moment are changing, so existing dehydration controlling method can not test the Vibration Condition of machine barrel and complete machine in real time, accurately, make dehydrating effect undesirable, and the vibrations of washing machine, noise, safety and life-span etc. are had an impact.
