3D Models of Washer / Washing Machines Appliances for the Laundry.
The first washing machine, launched into serial production, was created in 1907 by William Blackstone, she had a manual drive (there is also an opinion that Nathaniel Briggs did the first one). In Europe, the first washing machines began to be produced in Germany in 1900. Modern, electrically driven machines appeared in 1908. The mechanization of labor practically led to the disappearance of the laundress profession.
A machine of an activator type is a washing machine with the presence of an activator – a rotating shaft with blades or a disk that provides mixing during washing.
A special feature of this type of washer is low foaming, therefore, powders for hand washing are also suitable for use in activator type machines.
The basis of the design of a washer of an activator type is a tank made of stainless steel or plastic. The upper part (for loading clothes) – removable or flip cover. At the bottom or in the lower part of one of the walls there is an activator – a plastic flat circle or a shaft with protrusions – blades. The axis of the activator comes out of the tank, driven by an electric motor.
The activator machines of the Soviet period, as a rule, had a vertical tank of aluminum or stainless steel with a capacity of up to 30 liters and dimensions up to about 400x400x600 (height) mm, with a bottom in the shape of a semicircle. An activator (most often made of bakelite) with a diameter of about 200 mm, driven through a belt drive by a capacitor electric motor located under the tank, was located on one of the flat walls along the axis of the semicircle of the bottom. The control included a mechanical time relay for 15 minutes (with a specified accuracy of 1 minute), automatically turning on the electric motor alternately in different directions through pauses. Also (on later models) the engine power could be separately regulated (2 or 3 “wash modes”).
