Motor device of top opening barrel washing machine for accurately halting and positioning

Abstract

The invention relates to a motor device of a top opening barrel washing machine for accurately halting and positioning. A washing barrel of a washing machine consists of an outer barrel positioned on an outer layer and an inner barrel positioned in the outer barrel; both the inner barrel and the outer barrel are positioned in the shell of the washing machine; a motor is arranged beside the inner barrel and drives the inner barrel to rotate; a locking piece is arranged on the inner wall of the outer barrel; the motor is provided with a controller for controlling the locking piece to be at the locking position; and the inner barrel is controlled by the controller to be kept at a position in which clothes and articles are put into or taken out. A small block of magnetic steel is additionally arranged on a motor rotor and matched with a fourth Hall sensor on a motor stator, thus the motor can stop in the same posture; and when a direct current brushless motor is used on the top opening washing machine, the cover-opening position of the inner barrel faces upward and stops at the position at which the clothes and articles are put into or taken out by people, thereby realizing the humanized design of the washing machine and enabling the operation of the washing machine to become simple, comfortable and convenient.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a motor device for accurate stop positioning of a top-loading drum washing machine. technical background [0002] Brushless DC motors are widely used in the field of home appliances as the power to drive rotation. For the control of brushless DC motors for general washing, three Hall elements are usually used to control the operation and shutdown of the motor. During the control, the exact position of the motor when it stops cannot be controlled, and the stop position of the motor is affected by the inertia of the weight of the laundry. Due to the influence of the inner cylinder, it is impossible to accurately locate it. It is often necessary for the user to manually move the inner cylinder to find the opening of the inner cylinder. The operation is complicated and difficult. Contents of the invention [0003] The technical problem to be solved by the present invention is t...

For the control of brushless DC motors for general washing, three Hall elements are usually used to control the operation and shutdown of the motor. During the control, the exact position when the motor stops cannot be controlled, and the stop position of the motor is affected by the inertia of the weight of the laundry. Influenced by the influence, precise positioning is impossible, and the user often needs to manually toggle the inner cylinder to find the opening of the inner cylinder, which is complicated and difficult to operate
