Benefits of technology

The present invention provides a washing machine with a nozzle that sprays water into the drum at a broadened angle, improving washing and rinsing efficiency, and reducing water consumption. The nozzle has a vertical water-spraying angle in the range of 30-40 degrees or a horizontal water-spraying angle in the range of 110-130 degrees. The washing machine can also have a different right and left water-spraying angle for more effective spraying.

Problems solved by technology

Further, the washing water-circulating device increases friction between the laundry and a current of the washing water, thus increasing washing capacity.

second embodiment

[0069]FIG. 5 is a cross-sectional view of the nozzle of the washing machine in accordance with the present invention.

[0070] As shown in FIG. 5, the nozzle 74 of this embodiment has a horizontal spraying angle in the range of 110° to 130° so that the sprayed washing water is not spread over sides of the nozzle 74 and is directed concentrically to the inside of the drum 20. Other elements, such as the circulating device, in the second embodiment except for the nozzle 74 are substantially the same as those in the first embodiment and thus denoted by the same reference numerals even though they are depicted in different drawings. Thus, a detailed description of such elements in the second embodiment will be omitted because it is considered to be unnecessary.

[0071] The washing water (w) sprayed by the nozzle 74 tends to gradually get bent inwardly. Preferably, the nozzle 74 has an opened rear surface and an angle between both side surfaces of the nozzle 74 in the range of 130° to 140′ i...

fourth embodiment

[0079]FIG. 8 is a cross-sectional view of the nozzle of the washing machine in accordance with the present invention.

[0080] As shown in FIG. 8, the nozzle 74 of this embodiment has horizontal spraying angles (Y1, Y2) of different degrees. Other elements, such as the circulating device, in the fourth embodiment except for the nozzle 74 are substantially the same as those in the first, second or third embodiment and thus denoted by the same reference numerals even though they are depicted in different drawings. Thus, a detailed description of such elements in the fourth embodiment will be omitted because it is considered to be unnecessary.

[0081] The nozzle 74 includes the upper horizontal portion protruded horizontally from the lower end of the cylinder, the front vertical portion 76 protruded perpendicularly from the upper horizontal portion, the lower sloping portion 77 extended from the lower end of the front vertical portion 76 and located to be opposite to the through hole of th...

Abstract

Disclosed is a washing machine provided with a nozzle for spraying washing water into a drum at a broadened angle, thus improving washing efficiency and rinsing efficiency and reducing a quantity of the washing water consumed. The washing machine comprises a tub for containing washing water, a drum rotatably arranged in the tub for accommodating laundry, a motor for rotating the drum, and a washing water-circulating device for circulating the washing water so that the washing water in the tub is sprayed into the drum, wherein the washing water-circulating device includes a nozzle having a vertical water-spraying angle in the range of 30° to 40°.

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 washing machine provided with an improved nozzle for spraying washing water into a drum at a broadened angle. [0003] 2. Description of the Related Art [0004] Generally, washing machines are apparatuses for removing contaminants from laundry by the action of detergent and water. [0005] Such washing machines are divided into agitator-type washing machines, pulsator-type washing machines, and drum-type washing machines. [0006] The agitator-type washing machine washes laundry placed therein by rotating a rod rising from a central area of a washing tank in both directions. The pulsator-type washing machine washes laundry placed therein by means of friction between the laundry and a water current generated by rotating a pulsator having a disk shape installed on a lower portion of a washing tank in both directions. The drum-type washing machine ...
