Abstract

“DOUBLE-ACTION COMMAND TEMPORIZING FOR ELECTRONIC COMMANDS OPERATION ON SEVERAL DEVICES”, where a rotative button (4), through operating projections (5) in a plate of electronic circuit (1), forms a binary code giving information to an electronic microcontroller, concerning the updated position of the rotative button (4), being said position showed on the external panel of washing machines, drying machines and similar devices, as well as the time spent or to be spent during each function, and since the motor control is done by the microprocessor, it is possible to use a motor (7) which operation does not rely on its physical nature, being the said motor AC, CD, Synchronous, etc, therefore facilitating the use, being the energizing or de-energizing of all the electric and electronic circuit performed through the simple release or lock the contacts (10) and (11) against the projections (12) and (13).

Claims

1. ) DOUBLE-ACTION COMMAND TEMPORIZING FOR ELECTRONIC COMMANDS OPERATION ON SEVERAL DEVICES”

, formed by an electronic circuit plate (1) that, through semi-conductors (2) controls the electric energy flow to the devices under control as valves, motors and etc, which are connected to connectors (3), such plate (1) integrated to a rotative button (4) defined by several projections (5) previously distributed, to lock the electric contacts (6) that execute the function previously scheduled;

such electric contacts (6) acting near the electric motor (7), linked to a gearing set (8) and a ratchet mechanism (9);

such rotative button (4) including contacts (10) and (11) integrated as projections (12) and (13) energizing of electric and electronic circuit.

2. ) “

ELECTRONIC COMMANDS OPERATION SYSTEM ON SEVERAL DEVICES”

, according to the claim 1, defined by the projections (5) forming a binary code able to provide through de electronic circuit plate the updated information to the electronic microcontroller, concerning the position of the rotative button (4), position informed through the movement of the same rotative button (4), which rotation, after release or lock of the electric contacts (6), will place it in the program or part of the program desired and visualized through indications on the external panel of the machine, and after verify the button position (4) the microcontroller will execute the scheduled correspondent function, such movement conducted from the electric motor (7) to the rotative button (4), through the gearing set (8) and the ratchet mechanism (9).

3. ) “

ELECTRONIC COMMANDS OPERATION SYSTEM ON SEVERAL DEVICES”

according the claim 1, defined to avoid corrosion when the electric contacts of the lamina (6), performed in an isolate site by projections (5) of the rotative button (4), through a perpendicular movement relative the impress circuit position.

4. ) “

ELECTRONIC COMMANDS OPERATION SYSTEM ON SEVERAL DEVICES”

according the claim 1, defined by the energizing of the whole electric and electronic circuit through the contacts (10) and (11), activated only by the lock with the projections (12) and (13).

5. ) “

ELECTRONIC COMMANDS OPERATION SYSTEM ON SEVERAL DEVICES”

according to the claim 3, defined by the de-energizing of all the circuits of the machine, preventing shocks after the schedule conclusion, with the rotative button (4) placed in a way that the contacts (10) and (11) are open relative the projections (12) and (13).

6. ) “

ELECTRONIC COMMANDS OPERATION SYSTEM ON SEVERAL DEVICES”

according to the claim 1, defined by the utilization of any kind of electric motor, since the control of this motor is done by the microcontroller.
