Benefits of technology

[0011] It is another aspect of the present invention to provide a washing machine, which precisely senses whether a discharge pump malfunctions or foreign substances are present in the

Problems solved by technology

The suds are leaked to the front surface of the washing machine (for example, through a detergent inlet), or serves as a load obstructing the driving of a motor, thereby causing a difficulty in reaching a normal dehydration rpm (revolutions per minute).
In the conventional suds sensing method, there is a high probability of an error due to a va

Embodiment Construction

[0035] Reference will now be made in detail to the embodiment of the present invention, an example of which is illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiments are described below to explain the present invention by referring to the figures.

[0036]FIG. 1 is a sectional view of a washing machine of an embodiment of the present invention.

[0037] In FIG. 1, the washing machine of the present invention comprises a drum-type tub 11 installed in a main body 10 for containing washing water therein, and a rotary drum 12 rotatably installed in the tub 11.

[0038] The tub 11 slopes toward an installation ground of the washing machine at a designated angle (α) so that a front surface 11a of the tub 11, through which an opening 11b is formed, is located at a position higher than that of a rear surface 11c of the tub 11. The rotary drum 12 installed in the tub 11 has a same structure as that of the tub 11, so that a front...

Abstract

A washing machine and a suds sensing method thereof, in which a generation of suds is precisely sensed using discharge characteristics of suds in a water discharging operation. The suds sensing method of a washing machine includes determining whether a water level reaches a water discharge completion level in a predetermined water discharging time in a water discharging operation, determining whether the water level reaches a suds sensing level in a predetermined suds discharging time by controlling a drainage device such that the drainage device is turned on and off when the water level does not reach the water discharge completion level in the predetermined water discharging time, and sensing the suds by controlling the drainage device such that the drainage device is turned on and off in a predetermined range of the water level when the water level reaches the suds sensing level in the predetermined suds discharging time.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of Korean Patent Application No. 2005-9573, filed Feb. 2, 2005, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a method for sensing suds in a washing machine, and more particularly, to a washing machine, which senses a generation of suds using discharge characteristics of the suds, and suds sensing method thereof. [0004] 2. Description of the Related Art [0005] Generally, a conventional drum-type washing machine is an apparatus for washing laundry in a cylindrical rotary drum by lifting the laundry and then dropping the laundry when the rotary drum is rotated. Compared to a conventional pulsator-type washing machine, the drum-type washing machine has a longer washing time, but minimizes damage to the laundry and has a low water consumption rate,...
