Embodiment Construction

[0049] Specific embodiments of the present invention are described in detail below.

[0050] A dehydration control method for a drum washing machine, which divides the range of load eccentricity into n levels, and the eccentricity value increases from 1st level to n level. Note that, of course, the load eccentricity value can also be optimally selected and distributed according to the specific conditions of the washing machine.

[0051] The load eccentricity value is divided into 4 levels, 1, 2, 3, 4, and the order corresponds to the situation where the simulated eccentric weight is 400g, 600g, 800g, and 1000g. During each distribution detection, the inner cylinder accelerates from the shaking speed to the distribution speed with various accelerations. The acceleration is different, and the state of the clothes sticking to the wall of the cylinder is different. After several different attempts, a suitable state of balance. Corresponding to the washing program of ordinary loa...

Abstract

The invention relates to a dewatering control method for a roller washing machine. The dewatering control method includes a distribution detecting step and a dewatering step. The distribution detecting step includes that an eccentric value is divided into a plurality of gears, and during distribution, the gears are tried from low gears to high gears. If an actual eccentric value falls at a certain gear, low-speed dewatering is conducted, after a part of water is removed, an eccentric value is detected, and if the eccentric value still falls at the gear, medium-speed dewatering is conducted, otherwise, distribution is conducted again. Eccentric value detecting is also conducted during medium-speed dewatering, and if gears of an eccentric value are the same, final dewatering is conducted, otherwise, distribution is conducted again. During dewatering, low-speed dewatering and medium-speed dewatering are conducted first, eccentric value detecting is conducted, and final dewatering speed is relevant to the gears, and therefore, vibration of the washing machine can be fully reduced, noise is reduced, and box body collision can be avoided. Load with poor balancing performance is distributed at a high gear, dewatering at the set rotating speed is conducted, distribution detecting time can be effectively reduced, and power consumption and dewatering time can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to a dehydration control method of a drum washing machine. Background technique [0002] The existing drum washing machine generally detects the eccentric value before dehydration. When the detected eccentric value exceeds the set range, the washing machine will retry the distribution of clothes until the detected eccentric value is within the set range, which can effectively The protection of the washing machine will not be damaged due to excessive eccentric load during high-speed dehydration. Now the distribution detection generally accelerates from the shaking speed to multiple distribution speeds through different accelerations. The acceleration time is long, which leads to the imbalance between the distribution and the detection state. Since the uniformity of the distribution of the clothes after they are attached to the wall of the cylinder mainly depe...
