HOUSEHOLD APPLIANCE EQUIPPED WITH DEVICE OF DIAGNOSTICS OF POSITION OF DOOR LOCKING ELEMENT Russian patent published in 2012 - IPC A47L15/42 

FIELD: personal use articles.

SUBSTANCE: invention relates to a household appliance (10) comprising at least one door (14) and a device for determining an open or closed position of the door, made with the ability to measure inductance, and the devices for determining the position of the door contain at least one permanent magnet (34) and a Hall sensor (36) and at the open or closed position the doors give a signal corresponding to the position of the door, in particular, different from zero, characterised by the fact that the devices for determining the position of the door are connected to the controlling circuit (38) performed with the possibility, at least, to control the working capacity of devices for determining the position of the door, and the controlling circuit (38) includes a differential circuit (56) which compares the output signals of the Hall sensor (36) with the reference signal of the Hall sensor (36), and in the case of deviation of the output signals of the Hall sensor (36) from the reference signal it gives a signal, and a control device of the appliance (10) processes the signal and, depending on the specified signal initiates a variety of security measures in the form of switching off the pump, in particular, the circulating pump, or switching off the heating. In addition, the invention relates to a device (64) for determining the position of the door locking element.

EFFECT: invention is directed to create a household appliance with a self-test function.
