Washing machine

Abstract

A washing machine includes: a cabinet forming an external appearance and having an open upper portion; a reservoir hanging within the cabinet and allowing washing water to be put therein; a washing tub rotatably disposed within the reservoir and accommodating the laundry; and a spray nozzle spraying washing water into the washing tub such that one boundary of sprayed washing machine reaches a side wall of the washing tub and the other boundary of the sprayed washing water reaches the bottom of the washing tub, wherein the spray nozzle includes: a tube part forming a passage along which washing water is introduced; and a spray part connected with the tube part to spray washing water and disposed such that a spray face against which washing water discharged from the tube part splashes is bent at a certain angle with respect to a discharge direction of the tube part. The laundry can be effectively wet by increasing a spray range of washing water.

AI Technical Summary

Benefits of technology

[0009]In the washing machine according to an exemplary embodiment of the present invention, because washing water is simultaneously sprayed to the side wall and bottom of the washing tub, the laundry can be effectively wet and the washing performance and rinsing performance can be improved.

[0010]Also, In the washing machine according to an exemplary embodiment of the present invention, because washing water is directly sprayed to the laundry clinging to the side wall of the washing tub, the amount of consumed washing water can be reduced.

[0012]Moreover, because the washing machine according to an exemplary embodiment of the present invention includes the spray nozzle for spraying washing water to the bottom surface and the side wall of the washing tub and is formed such that the section of a flow path increases toward the side wall of the washing tub, a spray range with respect to the side wall of the washing tub can be increased, so the clothes or laundry can be easily wet.

[0013]Furthermore, in the washing machine according to an exemplary embodiment of the present invention, because the spray nozzle has flat upper, lower, left and right faces without a bent, washing water can be sprayed to be straightly stretched out. Because washing water is straightly sprayed, a spray speed can be improved and a spray range can be secured.

[0014]Also, because the washing machine according to an exemplary embodiment of the present invention includes the spray nozzle for spraying water to the interior of the washing tub, when a load of the washing tub is a minimum load, the spray nozzle sprays water at a height at which the spray nozzle can spray water to the side wall, whereby both the side wall spray and the bottom spray can be performed. Also, when the load of the washing tub is a maximum load, the spray nozzle sprays water to below a pre-set uppermost allowance spray point, thus preventing the occurrence of a phenomenon that sprayed water from flowing out of the washing tub. Thus, the side wall spray and bottom spray of the washing tub can be performed always regardless of the change in the height of the washing tub according to the load of the washing tub. Because the laundry can be effectively wet, the washing and rinsing performance can be improved.

Problems solved by technology

However, the related art washing machine performs washing such that washing water is supplied toward the bottom of a washing tub and, as the supplied washing water fills the washing tub, the laundry is wet.

Thus, in order to wet all the laundry, water must be supplied as high the laundry, causing a problem in that an excessive amount of washing water is consumed.

At this time, the laundry cling to the side wall of the washing tube due to the high speed rotation of the washing tub, and in order to rinse the clinging laundry, washing water must be supplied as high as the position whether the laundry cling, resulting in consumption of an excessive amount of washing water.

In particular, because the process is intermittently repeated during the washing process, further increasing the amount of consumed washing water.
