Benefits of technology

An object of the present invention is to provide a more accurate amount of water which is supplied to a washer and more precise washing parameters such as time intervals of washing, rinsing and dehydrating cycles, and a temperature of the supplied water so that the performance of the washer can be improved.

Problems solved by technology

However, the related art's method of determining the load weight has caused a significant problem in determining proper washing parameters such as time intervals of the washing, rinsing and dehydrating cycles, and a temperature of the supplied water, thus resulted in descending the performance of washers.

Embodiment Construction

Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

FIG. 2 illustrates a schematic block diagram of a drum washer in accordance with the present invention. The drum washer includes a key input unit 101 which receives an user's command for a washing operation, and a microprocessor 105, which determines a load weight by using the time, T1, during which a motor 106 rotates up to a pre-determined speed, and T2 during which the motor 106 comes to a full stop after the motor 106 is powered off. Then, the microprocessor 105 decides washing operation parameters such as time intervals of washing, rinsing and dehydrating cycles, and a temperature of the supplied water according to the determined load weight.

The washer also includes a water level sensor 103 which senses a...

Abstract

A washer and a method of determining a load weight are disclosed. The washer includes a tub which stores clothes to be washed, and a motor which rotates the tub. It further includes a microprocessor which measures an acceleration time during which the motor rotates up to a certain speed, and a deceleration time during which the motor comes from another certain speed to a full stop. Then, the microprocessor determines the load weight by using at least one of the acceleration and the deceleration times.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of Korean Application No. P2003-59805, filed on Aug. 26, 2003, which is hereby incorporated by reference. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washer, and more particularly, to a drum washer and a method of determining a load weight in the washer. 2. Discussion of the Related Art Generally, a washer performs a washing operation by executing washing, rinsing, and dehydrating cycles. Washers may be categorized into a pulsator, an agitator, a drum type, and the like based on how the washing cycle performs. Referring to FIG. 1, a body 1 includes a tub 2 inside of the body 1, which is connected by a damper (not shown in FIG. 1). Dirty clothes to be washed are placed in the tub 2, and a driving force of a motor 10 is transmitted through a belt 11, which rotates a drum 3. In the mean time, water is added through an inlet pipe 6 while a thermometer 4 (e.g., t...
