Washing machine with automatic drum balancing and universal self-centering system

FIELD: human vital needs satisfaction.

SUBSTANCE: in a washing machine with the automatic drum balancing and the universal self-centering system, the dynamic properties of the universal self-centering system are used. The torque is transmitted to the drum shaft from one of the bases of the universal self-centering system, and the balancing is carried out due to turning the drum shaft relative to the base axis of the universal self-centering system; for this purpose, pinions having gear engagement with a pinion fixed to the drum shaft of the washing machine are fixed to the pulleys of one base.

EFFECT: minimizing the degree of the rotating body deviation from the axis at the critical speed.

SUBSTANCE: method to control the supply of steam in washing machine is disclosed. The method of control comprises heating a predetermined volume in the channel which is connected to the tank of the washing machine to a higher temperature than the temperature of the rest volume in the channel, the direct supply of water to the heated predetermined volume for steam generation and supply of air flow to the heated predetermined volume for supplying the generated steam into the tank.

EFFECT: improvement of design.

FIELD: machine building.

SUBSTANCE: household appliance (1) includes housing (2) subject to vibrations and damper (9) attached to housing to damp vibrations and containing support frame (10) rigidly attached to housing (2); at least one first magnet (11, 11') rigidly attached to support frame (10) and at least one second magnet (12, 18, 12') installed on support frame (10) with possibility of sliding so that one of its magnet poles faces one of magnet poles of the first magnet (11). Besides, either the first magnet (11, 11') or the second magnet (12, 18, 12') is electromagnet (12, 12', 18). In addition, damper (9) includes AC power supply (13) of induction coil (17, 20) of electromagnet (12, 12', 18) so that back-and-forth movement of the second magnet (12, 18, 12') can be induced along support frame (10). Device includes electronic central control unit 15 of power supply (13) and is able to determine at every subsequent point of time the frequency of alternating current that is to be supplied to induction coil (17, 20) of electromagnet (12, 12', 18) for creation of mechanical vibrations in opposite phase to mechanical vibrations of housing (2) of the device in order to decrease the amplitude of its mechanical vibrations.

EFFECT: lower amplitude of mechanical vibrations.
