WATER-CONSUMING HOUSEHOLD ELECTRICAL DEVICE AND VALVE FOR SUCH DEVICE Russian patent published in 2010 - IPC F16K31/70 A47L15/42 

FIELD: machine building.

SUBSTANCE: group of inventions relates to variable flow control facilities of actuating medium, control of which is provided by thermal drives. Water-consuming household electrical device, particularly dishwashing machine or clothes washer with valve (1) for such device contains casing (2) of valve, cavity (3) of valve and interconnect devices for supply (4) and withdrawal (5) of medium. In casing (2) it is installed body (6) of valve. For driving of body (6) of valve into closed position and into open position of valve (1) it is an element (20) with shape memory effect. The latter is implemented from unstrained state of rest through strained stressed state more into from unstrained state of rest. It is also device for changing of effort direction, by means of which element (20) with shape memory effect, particularly of unidirectional type, drives body (6) of valve into closed position and into open position of valve (1) exclusively either at conversion into its stressed state, or at conversion into state of rest. Device for changing of direction of effort contains reversible mechanism (13) with crank guide (14) or corresponds lever mechanism.

EFFECT: invention provides increasing of durability and reliable performance of valve and water-consuming household electrical device, using such valve.
