Embodiment Construction

[0034] Please refer to FIG. 1 , which is a circuit for detecting the occurrence of a barrel collision phenomenon in the prior art. In the figure, one end of the vibration switch S10 is connected to the power supply Vcc, and the other end is connected to the input port A of the microcontroller through the resistor R10. The function of the switch R10 is to protect the input port of the microcontroller. The C10 connected in parallel with the vibration switch S10 is used to filter the high frequency interference on both sides of the vibration switch S10, and the capacitor C11 is connected between the input port A of the single-chip microcomputer and the power ground to play a filtering role. When the barrel collision phenomenon occurs, the bottom of the outer barrel collides with the box body, and the upper end of the outer barrel touches the vibration switch S10 and disconnects.

[0035] The above circuit cannot detect the unbalance of the rotation of the inner barrel, and can o...

Abstract

This invention discloses one washing machine drying speed control device, which comprises outside barrel and Hall displacement sensor and matched magnetic elements. This invention discloses one drying speed control method, which comprises the following steps: a, testing distance between washing machine outside cylinder and case; b, computing current bias reference values according to washing machine self parameters and current speed and clothes volume; c, judging the distance between outside barrel and case within current reference parameters range; if yes, then entering step d, if not then entering step e; d, improving speed; e, lowering rotation speed.

Description

technical field [0001] The invention relates to a washing machine, in particular to a dehydration speed control device of a washing machine and a method for controlling the dehydration speed of a washing machine. Background technique [0002] When the washing machine is dehydrating, the faster the rotation speed of the inner tub, the faster the dehydration speed, the more thorough the dehydration, and the higher the efficiency. In the past, the washing machine did not have a speed regulation function and could not control the spin speed, and could only spin at a constant speed; now, many washing machines have begun to use technologies such as frequency conversion speed regulation to control the spin speed, and spin at the highest possible speed to improve dehydration. efficiency. [0003] However, when the washing machine is dehydrating, if the clothes in the tub are placed unbalanced, the inner tub will not be able to rotate normally. In severe cases, the outer tub will co...
