Dewatering method for drum washing machine

Abstract

The invention relates to a dehydration method for a cylinder washing machine, comprising a plurality of procedures: the single load detection procedure, after the motor accesses to a set voltage, the rotation number of the cylinder is detected at a set time to determine whether the washing packet in the cylinder is a single load. The washing packet opening procedure, if the washing packet is a single load, the motor is accelerated and decelerated repeatedly in the washing packet flowing rpm interval and the washing packet in execution is opened; simultaneously, the velocity deviation of the cylinder is detected to determine whether to do eccentricity detection. The single load eccentric magnitude detecting procedure, if the velocity deviation is lower than the reference velocity deviation, the eccentric magnitude of the washing packet is detected and is compared with the reference velocity deviation. The single load main dehydration procedure: if the eccentric magnitude is lower than the reference eccentric magnitude or the velocity deviation is higher than the reference velocity deviation, the cylinder rotates at a high speed through the motor and does centrifugal dewatering for the washing packet. The invention has the advantage of shortened single load dehydration time.

Description

technical field [0001] The invention relates to a dehydration method of a drum washing machine. Background technique [0002] Generally speaking, the washing machine uses the action of water and detergent. In order to remove the dirt on clothes, pillows, etc. Cleaning device. [0003] Such as figure 1 As shown, a general drum washing machine includes the following parts: a housing 2 forming an appearance; on the inside of the housing 2, it can be buffered and supported by a spring 4 and a shock absorber 6, and is used for a washing bucket containing washing water 8; rotatably installed on the inside of the above-mentioned washing bucket 8, and its outer peripheral surface is formed with a plurality of water holes 10A, and is used to accommodate the drum 10 of the washing bag; installed on the inner surface of the above-mentioned drum 10, when the above-mentioned drum 10 rotates, In order to make the washing bag fall under the action of gravity, the lifting device 12 that ...

Problems solved by technology

However, in the case of the above-mentioned short single load, even if the unpacking of the washing bag (section c) and the detection of eccentricity (section b) are repeated several times, the state of eccentricity will be maintained inside the drum 10.

[0029] In addition, in the dehydration method of the drum washing machine in the prior art, if the eccentric state has not been released after repeated setting times of unpacking the washing bag (section c) and eccentricity detection (section b), it will be judged that the above-mentioned drum 10 is Laundry bags placed in a single load and forced into the main spin step

[0030] Therefore, in the case of the above-mentioned short single load, since unnecessary unpacking of the washing bag (section c) and eccentricity detection (section b) are repeatedly performed for a set number of times, the entire dehydration time of the front-loading washing machine 1 will be prolonged, so that users are dissatisfied

[0031] Since the time for judging the single load of the washing bag is lengthened, it is not possible to accurately determine whether the single load is a long single load or a short single load, so that the dehydration process of the washing bag cannot be performed with the best dehydration method; and, Weaken the vibration characteristics of the front-loading washing machine 1 in the main spin-drying step, thereby causing greater vibration in the above-mentioned front-loading washing machine 1

[0032] And, in the prior art washing bag untie (c section), the rotation direction of the above-mentioned drum 10 will be switched by the set number of times, and the eccentricity of the washing bag will be reduced, so that the rotation of the above-mentioned drum 10 will be slow or Stop and wait for the interval where the washing bag is not unwrapped, which will reduce the effect of unpacking the washing bag and prolong the time for unwrapping the washing bag accordingly

[0033] And, when the above-mentioned washing bag is untied (section c) for a set number of times, it will automatically enter the eccentricity detection (b section) in the prior art regardless of the eccentric state of the above-mentioned washing bag, thereby making the above-mentioned eccentricity Detection failed to take place in proper period and resulted in increased number of off-center detections
