Washing machine and control method thereof

Abstract

A washing machine provided with a structure thereof capable of draining and circulating by using a single pump and capable of enhancing washing performance by using a circulation of water and a rotation of a drum, and a control method thereof, in which the structure of the washing machine is simplified through the change of the flow path that enables the draining and the circulation of water by using a general pump while decreasing the number of the components of the washing machine. The manufacturing cost of the washing machine is reduced, because the washing machine accelerates the dissolution of detergent by generating large amount of bubbles by using the circulation of water and the rotation of the drum, without additional components, thereby washing performance of the washing machine is enhanced, and by maintaining the bubbles that are generated, the non-tangible quality that a user feels in the course of washing is enhanced.

AI Technical Summary

Benefits of technology

[0012]In an aspect of one or more embodiments, there is provided a washing machine provided with a structure thereof capable of draining and circulating by using a single pump and capable of enhancing washing performance by using a circulation of water and a rotation of a drum, and a control method thereof.

[0047]In an aspect of one or more embodiments of a washing machine and control method thereof, by using a conventional drain pump, through the switch of the flow path that enables the draining and the circulation of water, the structure of the washing machine may be simplified while the number of the components of the washing machine may be decreased, and thereby the manufacturing cost of the washing machine may be reduced.

[0048]In an aspect of one or more embodiments of a washing machine and control method thereof, by generating large amount of bubbles by using the circulation of water as well as the rotation of the drum, without additional components, the dissolution of detergent may be accelerated, and thereby washing performance of the washing machine may be enhanced, and by maintaining the bubbles that are generated, the non-tangible quality that a user feels in the course of washing may be enhanced.

Problems solved by technology

However, a conventional washing machine is needed to be provided with water filled up to the space between the tub and the drum to perform a washing, and thus the consumption of water is large and the detergent is needed to be used in proportion to the amount of the water, and in a case of performing a washing using heat, as to increase the temperature of the water being input into the conventional washing machine, the amount of energy is as large in proportion to the amount of the water.

In addition, as to enhance washing performance of the conventional washing machine, washing water is needed to be effectively delivered to the laundry that is positioned at a center of an inner portion of the conventional washing machine, but due to the structural characteristics of the conventional washing machine, without additional use of water, the height ascension of the washing water is difficult while some of the detergent that is being input into the conventional washing machine along with the washing water may be wasted without being dissolved, and thus the concentration of the washing water may be reduced, and accordingly, a limitation in implementing a high-concentration washing may be present.

However, as to circulate the water or to generate bubbles at an inside the tub, additional components such as a pump, a hose, and other injection-molded product, are needed to be added thereto, and accordingly, an additional process is added in manufacturing the conventional washing machine and the material cost of the conventional washing machine is increased.
