KR960010961A - Washing stroke control method and control device using vibration sensor - Google Patents

Abstract

The present invention relates to a fully automatic washing machine, and more particularly, to a washing stroke control method and control device using a vibration sensor to prevent washing of the laundry by detecting the frequency of the washing tank during the washing process to control washing and rinsing. The washing machine does not consider the influence of the washing factors when the user washes and rinses, and thus performs the turbid water stroke, or when the laundry is unbalanced, the laundry is rewatered to the washing tank when the water is dehydrated to dehydrate the unbalanced laundry so that the washing machine vibrates and There was a problem that noise occurs and the washing machine is easily broken.

Therefore, in order to solve the conventional problem, the present invention attaches a vibration sensor unit to the washing tank to sense the amount of vibration generated in the washing tank when driving the washing machine to control the washing stroke, and to suppress the kinking during washing and rinsing. In addition, to control the progress of the imbalance stroke during dehydration, it is applied to a washing machine.

Claims (2)

A case 11 for supporting the entire washing machine, a washing tank 12 and a dehydrating tank 13 for washing and dehydrating laundry, a clutch 15 and a motor 16 for controlling power of the washing blade 14, The vibration sensor unit 17 attached to the outer surface of the washing tank 12 for detecting the vibration of the washing tank 12 during the washing process, and the vibration signal detected by the vibration sensor unit 17 receives the most when washing and rinsing A storage unit for storing the vibration amount of the microcomputer 18 which selects an appropriate washing factor and controls each part of the washing machine and the washing tank 12 detected by the vibration sensor unit 17 according to the washing state of the washing tank 12 ( 19 and the comparison unit 20 for comparing the vibration amount stored in the storage unit 19 with the vibration amount of the washing tub 12 detected by the vibration sensor unit 17 and the comparison unit 20 Washing stroke control device using a vibration sensor consisting of a control unit 21 for receiving the received signal to control the washing progress through the motor (16). The first process of determining whether the rotation speed (RPM) of the washing tank 12 is greater than or equal to a predetermined value (X) during the dehydration stroke, and if the rotation speed of the washing tank 12 is greater than or equal to the predetermined value, is detected by the vibration sensor unit 17. A second process of detecting the frequency N of the washing tub 12 and a washing factor B ₁ -B _{n + 1} corresponding to the frequency N detected by the vibration sensor 17. After the process 3 and the washing factor (B ₁ -B _{n + 1} ) corresponding to the electric power (N) detected by the vibration sensor unit 17 as a result of the third process is determined, it is applied to the microcomputer 18 and then present. Washing machine dehydration time (T) @ The washing stroke control method using a vibration sensor configured to proceed to the fourth step of controlling the washing stroke by determining whether the set dehydration time (A). ※ Note: The disclosure is based on the initial application.
