Description
- This application claims the benefit of Korean Patent Application No. 10-2007-57877, filed Jun. 13, 2007, which is hereby incorporated by reference as if fully set forth herein.
- 1. Field of the Invention
- The present invention relates to a washing machine and a method for controlling the same, and more particularly, to a washing machine, in which a washing operation is set according to obtained washing data to perform washing of laundry, and a method for controlling the same.
- 2. Discussion of the Related Art
- Generally, washing machines are apparatuses, which remove various contaminants attached to clothing and bedding using emulsification of a detergent and friction between water and laundry. Recent washing machines continuously carry out a series of processes, i.e., washing, rinsing, and dehydrating processes.
-
FIG. 1 is a perspective view of a conventional washing machine having a detergent box. - As shown in
FIG. 1 , aconventional washing machine 1 includes a cabinet 2 forming the external appearance of thewashing machine 1, a tub (not shown) horizontally installed in the cabinet 2 to contain washing water, and adrum 4 rotatably installed in the tub to wash laundry put into thedrum 4. A plurality oflifters 6, which lifts the laundry such that the laundry at a designated height can fall by gravity, is installed on the inner surface of thedrum 4. Further, a motor (not shown) generating rotary force of thedrum 4 is installed at the rear of the tub. - A
cabinet cover 8 provided with a laundry entrance H, through which the laundry is put into and taken out of thewashing machine 1, is mounted on the front surface of the cabinet 2, and acontrol panel 10 including amanipulation unit 10 a for manipulating the operation of thewashing machine 1 and adisplay unit 10 b for displaying the operation of thewashing machine 1 is mounted on the front surface of the cabinet 2 above thecabinet cover 8. - A
door 12 for opening and closing the laundry entrance H is rotatably installed on thecabinet cover 8, and atop plate 14 is mounted on the upper surface of the cabinet 2. - A
receipt unit 10 c is formed at one side of thecontrol panel 10, and adetergent box 20 for putting a main detergent or a subsidiary detergent into thewashing machine 1 is detachably inserted into thereceipt unit 10 c. - The
detergent box 20 is disposed on a water supply channel of thewashing machine 1 such that the main detergent and the subsidiary detergent together with supplied water can be fed into the tub. - The
detergent box 20 has a hexahedral structure, the upper surface of which is opened, and includes an internal space, into which the detergents are put. - That is, the internal space of the
detergent box 20 is divided into a main detergent storing unit, in which a powdery detergent is stored such that the detergent together with water is supplied during main-washing, and a subsidiary detergent storing unit, in which a liquid detergent, such as a softening agent or a bleaching agent, is stored. - Hereafter, an operation of the above conventional washing machine will be described.
- Laundry is put into the
drum 4, and proper amounts of a powdery detergent and a liquid detergent are respectively put into the main detergent storing unit and the subsidiary detergent storing unit of thedetergent box 20. - When power is applied to the
washing machine 1, water is supplied to the tub, the detergents in thedetergent box 20 are washed by the sprayed water and are supplied to the tub. Then, thedrum 4 is rotated by the motor, and thus washing, rinsing, and dehydrating of the laundry is carried out. - However, since a user directly measures the amounts of the detergents and puts the detergents into the
detergent box 20, the conventional washing machine causes a difficulty in putting the proper amounts of the detergents into thedetergent box 20 according to the kinds of the detergents, the weight of the laundry, or the contamination degree of the laundry. - Further, since designated amounts of the detergents required to perform the washing of the laundry one time must be put into the
detergent box 20, the conventional washing machine causes inconvenience of supplying the detergents to the inside of thedetergent box 20 whenever a user wants to wash laundry. - Accordingly, the present invention is directed to a washing machine and a method for controlling the same.
- One object of the present invention is to provide a washing machine, which determines a proper amount of a detergent according to the kind of the detergent and the weight of laundry, and thus allows the proper amount of the detergent to be automatically put into the washing machine, and a method for controlling the same.

detergent supply pipe 210, in case that thedetergent supply pipe 210 is clogged, will be described. - Generally, in case that washing water is supplied to the
washing unit 111, the fourth valve V4 is opened on condition that the first valve V1 is closed and thus the washing water is supplied from thewater supply unit 230 to thewashing unit 111, and in case that a detergent is put into thetub 112, the first valve V1 is closed, the second and third valves V2 and V3 are opened, thepump 220 is driven, and thus the detergent is supplied from thedetergent storing unit 120 to thewashing unit 111. - However, in case that the
detergent supply pipe 210 is clogged, the second and fourth valves V2 and V4 are closed and the first and third valves V1 and V3 are opened, and thus the washing water is supplied from thewater supply unit 230 to thedetergent supply pipe 20 through thebypass pipe 250, thereby washing thedetergent supply pipe 210. - Hereinafter, with reference to
FIG. 5 , a method for controlling theabove washing machine 100 in accordance with an embodiment of the present invention will be described in more detail. - First, in case that a new detergent is used, the
reading unit 130 obtains data regarding the corresponding detergent from the data tag (S100). - Herein, the data regarding the detergent include data regarding the kind of the detergent.
- Concurrently, the
weight measuring unit 140 detects data regarding the weight of laundry to be washed (S110). - Further, the
contamination degree sensor 150 detects the contamination degree of the laundry to be washed (S120). - The
control unit 160 extracts a proper amount of the detergent based on the data obtained from the data tag, theweight measuring unit 140, and thecontamination degree sensor 150, and allows a user to confirm the extracted data through the display unit 132 (S130). - In case that the data tag is a data tag including the data regarding the kind of the detergent, a corresponding data is extracted from the storing
unit 170, in which data regarding proper amounts of detergents according to kinds of the detergents and weights of laundry are stored, during the above extracting process. - Thereafter, the washing machine supplies the proper amount of the detergent to the
washing unit 111 based on the extracted data (S140). - Thereafter, the data regarding the detergent are automatically stored in the
storing unit 170, and thus in case that the same detergent is used, a washing operation is carried out according the stored data (S150). - The washing machine of the present invention recognizes a proper amount of a liquid detergent according to the kind of the detergent and the weight of laundry to be washed, and allows the proper amount of the liquid detergent to be put into the
washing unit 111. - The washing machine of the present invention contains a large amount of the detergent, and thus reduces the trouble of supplying the detergent whenever a washing operation is carried out.
- It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
