Problems solved by technology

[0025] If the internal temperature of the drum is sufficiently increased to optimize the washing conditions of the washing tub 20 or the drum 30, although this can reduce the water consumption, at this time, the heat generated by the heater (not shown) for a long time is required to Raise the temperature inside the drum, which is not very effective considering the large energy consumption
[0026] At the same time, if the laundry tub is cleaned with laundry powder in it, the laundry powder will generate a lot of foam, hinder the rotation of the laundry tub, and put a load on the motor that drives the laundry tub to rotate, resulting in energy loss

Embodiment

[0142] Another preferred embodiment of the present invention will be described in detail with reference to FIG. 11 .

[0143] After the user selects the washing tub cleaning mode, the controller controlling the operation of the washing machine operates the steam supply device to supply steam to the tub 120 or the drum 130 (S140).

[0144] When steam is supplied to the tub 120 or the drum 130, the controller controls the drum 130 to continuously rotate to actually perform a tub washing cycle (S420).

[0145] That is, the washing cycle of the washing tub is performed by forming a high-temperature, high-humidity environment inside the washing tub 120 or the drum 130 by using high-temperature and humid steam, and through continuous rotation of the drum.

[0146] In this case, it is preferable that the rotation speed of the drum 130 is equal to or lower than that of a washing cycle performed in only one direction.

[0147] Of course, the drum 130 also alternately rotates in the op...

Abstract

The present invention relates to a method for washing a washing tub (120) in a washin machine, and a washing machine having a washing tub washing course provided thereto for enabling washing tub (120) washing by the same, and more particularly, to a method for washing with a washing machine which makes effective washing tub washing, with a small amount of washing water consumption, a lower power consumption, and high washing effect; and a washing machine having the same applied thereto. A method for washing a tub (120) or a drum (130) in a washing machine having the tub (120), the drum (130) rotatably mounted in the tub (120), and a steam supply unit for supplying steam to the tub (120), includes a steam supply step for supplying steam to the tub by using the steam supply unit.

Description

technical field [0001] The invention relates to a method for cleaning a washing bucket in a washing machine, and a washing machine having a washing bucket cleaning process for cleaning the washing bucket by the above method, and specifically relates to a water-saving, power-saving, high-efficiency , and a method for effectively cleaning a washing tub by using a washing machine, and a washing machine with the above-mentioned advantages. Background technique [0002] Generally, among washing machines, there are a pulsator type washing machine having a vertical drum and a drum type washing machine having a horizontally arranged drum. [0003] Since the drum type washing machine has a horizontal drum, the drum type washing machine performs washing by dropping laundry. [0004] Fig. 1 and Fig. 2 schematically show drum-type washing machines in the prior art, respectively. [0005] The drum type washing machine has a main body 10 , a washing tub 20 located in the main body 10 , ...
