what household items became widespread after worrld war 1?

Answer 1

Tungsten Filaments in light bulbs (invented 1915)

Pop-up toasters (invented 1918)

Answer 2

Widespread might be hard to justify but just about everything we 21st Century folks have to come to expect to find in the kitchen began appearing after the Great War. Actual honest to goodness refrigerators, electric toasters, and electric mixing machines all began trickling into the 'modern home.'

"""Two of the first home refrigerators both appeared in Fort Wayne, Indiana, where, in 1911, General Electric company unveiled a unit invented by a French monk. In 1915 the first "Guardian" refrigerator - a predecessor of the Frigidaire - was assembled in a wash house in a Fort Wayne backyard.
Kelvinator and Servel models were among some two dozen home refrigerators introduced to the U.S. market in 1916. In 1920 the number had increased to more than 200. Compressors were generally driven by belts attached to motors located in the basement or in an adjoining room.
In 1918 Kelvinator introduced the first refrigerator with any type of automatic control. One manufacturer's 1922 model had a wooden cabinet, a water-cooled compressor, two ice cube trays and nine cubic feet of storage space. It cost $714. In 1923 Frigidaire introduced the first self-contained unit. Steel and porcelain cabinets began appearing in the mid-20s.
In the 1920s and '30s, consumers were introduced to freezers when the first electric refrigerators with ice cube compartments came on the market. Mass production of modern refrigerators didn't get started until after World War II."""

"""A wringer, invented in 1861, was added to the washer. Metal tubs replaced wooden types around 1900. Drive belts made possible use of steam or gasoline engines in the early 1900s and electric motor power for the first time in 1906. Maytag's first washer, built in 1907, was operated by a rotary handle and a flywheel underneath.
In 1922 The Maytag Company introduced a system of forcing water through the clothes by means of an agitator rather than dragging the clothes through the water. This system is most commonly used now. ""
