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

The present invention is a washing machine that can spray water to both the side wall and bottom of the washing tub, which improves the wetness and washing performance of the laundry. The spray nozzle has a flat face without a bend, allowing for straight spraying, which improves spray speed and range. When the washing tub is at its minimum load, the spray nozzle sprays water to the side wall and bottom, while at its maximum load, the spray nozzle prevents water from flowing out of the washing tub. This ensures both side wall and bottom spraying, regardless of the load on the washing tub. The spray nozzle also includes a flat spray range that allows for effective wetness of the laundry. This washing machine demonstrates improved performance and efficiency in wetting laundry and rinsing clothes.

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.
