Heating apparatus of washing machine and washing method thereof

Abstract

A heating apparatus of a washing machine and a washing method thereof. The heating apparatus includes a circulation channel installed outside a tub for connecting one side of the tub to the other side of the tub, and an orifice, water drop supply device for supplying water, an air blower for circulating the water, and a heater, which are sequentially installed in the circulation channel. The heating apparatus supplies steam or hot wind to the tub in a washing or rinsing operation, thereby improving the washing capacity of the washing machine, minimizing the time taken to perform the washing or rinsing operation and an energy consumption rate, and allows the washing machine to perform a drying operation using hot wind without any additional element, thereby diversifying its functions and minimizing production costs.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a washing machine, and more particularly to a heating apparatus of a washing machine, which provides hot wind or steam in a washing or rinsing mode, and is also operated in a drying mode, and a washing method thereof. [0003] 2. Description of the Related Art [0004]FIG. 1 is a longitudinal-sectional view of a conventional washing machine. [0005] The conventional washing machine comprises a cabinet 2 provided with a door 1 installed on the front door thereof, a tub 4 placed in the cabinet 2 and supported by a damper 3, a drum 6 rotatably installed in the tub 4 and provided with a plurality of water pores 5 formed through the cylindrical surface thereof, and a driving device 10 installed outside the tub 4 and connected to the drum 6 by a rotary shaft for rotating the drum 6.
