Dehydration controlling method for drum washing machine

Abstract

This invention relates to the dehydration controlling method of the barrel roller washing machine, which can accurately sensors the quantity of the washing and the shake of the roller is the minimum. The dehydration method of this invention includes the counter of water supplying times during the cleaning process, according to the times of the supplying water, it can judge the stage of the first quantity of the washing. After the finishing of the clean and before the main dehydration, it can calculate the time when the speed of barrel roller gets the fixed value. According to the calculating time, it can judge the second stage of clothings. According to the first and second clothings value, it can determine the ultimate value of the clothings stage. According to the ultimate value of the clothings, it can determine the condition of dehydration, and then it can process the dehydration stage. This invention applies to the dehydration for the barrel roller washing machine, it can improve the sensor accurate of the clothing value, because it can more accurately judge the value of the clothings, it can get more distributing effect of the clothings and reduce the shake and vibration of the washing machine during the dehydration.

Description

[0001] Technical Field The present invention relates to a front-loading washing machine. In more detail, it is a dehydration control method for drum washing machines that can accurately sense the amount of laundry and minimize the vibration of the drum Background technique [0002] The drum washing method is to put the detergent, washing water and laundry into the drum, and use the friction between the drum and the laundry to receive the driving force of the motor to wash. There is almost no damage to the clothes, and the laundry does not It will be entangled with each other, and the washing effect of frustrating and beating can be obtained. [0003] Figure 1 is a schematic cross-sectional view of important parts of the structure of a common drum washing machine. As shown in the figure, a drum washing machine is provided with an outer tub 2 inside a housing 1, and a drum 3 is rotatably provided in the center of the inner tub 2. [0004] On one side of the lower part of the o...

Problems solved by technology

[0021] Although the existing dehydration process considers the amount of laundry in order to improve the dispersion effect of the laundry, it is difficult to perceive the exact amount of laundry if the laundry is severely twisted at the end of the cleaning process.

[0022] That is, when the amount of clothes is perceived and judged only by the amount of clothes behind the washing process, the accuracy is low, and it is possible to mistake multiple pieces of clothing for a single piece of clothing

[0023] Therefore, a good clothes dispersion effect cannot be obtained, and during the dehydration process, the shaking and vibration of the drum are caused to increase the noise
