WHAT IS WASHING MACHINE? A washing machine is a machine used to wash laundry, such as clothing and sheets.

IN EARLY TIMES, WE WASH BY HAND Laundering by dry hand involves soaking, beating, scrubbing, and rinsing dirty textiles. The entire process often occupied an entire day of hard work, plus drying and ironing.

DEVELOPMENT OF WASHING MACHINE ( 1 ) A drawing of an early washing machine appeared in the January 1752 issue of The Gentlemen's Magazine, a British publication. Jacob Christian Schäffer's washing machine design was published 1767 in Germany.

DEVELOPMENT OF WASHING MACHINE (2) In 1782, Henry Sidgier issued a British patent for a rotating drum washer. This crude agitator technology was hand-powered, but still more effective than actually handwashing the clothes.

DEVELOPMENT OF WASHING MACHINE (3) The earliest special-purpose mechanical washing device was the washboard, invented in 1797 by Nathaniel Briggs of New Hampshire.

DEVELOPMENT OF WASHING MACHINE ( 4 ) By the mid-1850 s steam-driven commercial laundry machinery were on sale in the UK and US. The rotary washing machine was patented by Hamilton Smith in 1858. As electricity was not commonly available until at least 1930, some early washing machines were operated by a low-speed, single-cylinder hit-and-miss gasoline engine.

DEVELOPMENT OF WASHING MACHINE (5) The first automatic washing machine came into use in 1937. In appearance and mechanical detail, this first machine was not unlike the front loading automatic washers produced today.

DEVELOPMENT OF WASHING MACHINE ( 6 ) Features available in most modern consumer washing machines: ①Delayed execution: a timer to delay the start of the laundry cycle ②Predefined programs for different laundry types ③Rotation speed settings ④Variable temperatures, including cold wash ⑤Child lock ⑥Steam ⑦Time remaining indication

CONCLUSION: Clothes washer technology developed as a way to reduce the manual labor spent. The earliest machines were hand-operated and constructed from wood, while later machines made of metal and get power from electricity. Today’s modern washing machine let people feel washing is enjoyment and leisure.
