The invention provides a digital lock (100, 1001, 1002) including at least two magnets. One magnet is a semi hard magnet (310) and the other magnet is a hard magnet (320). The hard magnet (320) is configured to open or close the digital lock (100, 1001, 1002). The semi hard magnet (310) and the hard magnet (320) are placed adjacent to each other. A change in magnetisation polarisation of the semi hard magnet (310) is configured to push or pull the hard magnet (320) to open or close the digital lock (100, 1001, 1002).

The invention provides a digital lock including at least two magnets. One magnet is a semi-hard magnet and the other magnet is a hard magnet. The hard magnet is configured to move to close the digital lock in the event of malicious attack, blocking the intruder thereby the magnets acting as a blocking pin, and the mechanical and/or electromagnetic energy of the attack is configured to move the hard magnet to seal the digital lock from the intruder.

Provided are a motor driving circuit, a control method therefor, and a driving chip. The motor driving circuit includes a logic module and a push-pull module, a channel selection module, an instruction recognition module, and an isolating switch module. An input signal is outputted by the logic module and the push-pull module to control the motor. The channel selection module is configured to select a channel for the input signal to make the input signal to be connected to the isolating switch module or the instruction recognition module, or disconnected. The instruction recognition module is configured to perform a corresponding operation on the isolating switch module according to an inputted instruction. The isolating switch module is configured to receive an instruction of the channel selection module and an instruction of the instruction recognition module to connect or disconnect the logic module.

The invention provides a magnetic actuator (100, 1001, 1002) including at least two magnets. One magnet is a semi hard magnet (310) and the other magnet is a hard magnet (320). The hard magnet (320) is configured to open or close the magnetic actuator (100, 1001, 1002). The semi hard magnet (310) and the hard magnet (320) are placed adjacent to each other. A change in magnetization polarization of the semi hard magnet (310) is configured to push or pull the hard magnet (320) to open or close a digital lock realised with the magnetic actuator 100, 1001, 1002. The magnetic actuator of the invention can also be used to realise a valve.

A digital lock including at least two magnets is disclosed. One magnet is a semi-hard magnet and the other magnet is a hard magnet. The hard magnet is configured to open or close the digital lock. The semi hard magnet and the hard magnet are placed adjacent to each other. A change in magnetization polarization of the semi hard magnet is configured to push or pull the hard magnet to open or close the digital lock.

A door lock for a domestic electrical appliance comprises a movably arranged locking member, which is selectively adjustable into an unlocking position and a locking position and in the unlocking position permits the opening of a closed door of the domestic appliance and in the locking position is in blocking engagement with a blockable component, at least when the door is closed. The blocking engagement causes the closed door to be blocked against opening. The door lock further comprises an electrically controllable actuator for actuating the locking member, and an electrical door detection switch that switches depending on the closing of the door. The doer lock also comprises an electrical auxiliary switch device, which selectively opens or closes an electrical shunt path to the door detection switch depending on the position of the locking member.

A door lock for a domestic electrical appliance includes a locking member which is electrically switchable between an unlocking position and a locking position, which locking member in the unlocking position allows a closed door of the domestic appliance to be opened and in the locking position is in blocking engagement with a blockable component at least when the door is closed, and an auxiliary member, separate from the blockable component, which is movable in dependence on the closing of the door from a release position into a blocking position. The blocking engagement effects blocking of the closed door against opening. In the release position, the auxiliary member allows the locking member to be transferred from the unlocking position into the locking position; in contrast, in its blocking position, the auxiliary member blocks the locking member against being transferred from the unlocking position into the locking position.

A door lock for a domestic electrical appliance such as, for example, a washing machine of the top loader type includes a lock module, a housing shell for the floating mounting of the lock module on a housing wall portion of a body of the domestic appliance, a locking member which is arranged to be movable between an unlocking position and a locking position, and an electrically controllable actuator for actuating the locking member. The lock module has an insertion opening for insertion of a closing element on closing of the door of the domestic appliance. The locking member in its unlocking position allows the closing element to move out of the insertion opening and in the locking position effects blocking of the closing element against moving out of the insertion opening. At least one centring slope for the closing element is formed at the insertion opening.

Electromechanical lock utilizing magnetic field forces. An actuator is moved (1202) from a locked position (260) to an open position (400) by electric power. In the locked position (260), a permanent magnet arrangement directs (1204) a near magnetic field to block an access control mechanism to rotate, and simultaneously the permanent magnet arrangement attenuates (1206) the near magnetic field towards a far magnetic break-in field originating from outside of the electromechanical lock. In the open position (400), the permanent magnet arrangement directs (1208) a reversed near magnetic field to release the access control mechanism to rotate, and simultaneously the permanent magnet arrangement attenuates (1210) the reversed near magnetic field towards the far magnetic break-in field.

The invention provides a digital lock including at least two magnets. One magnet is a semi-hard magnet and the other magnet is a hard magnet. The hard magnet is configured to move to close the digital lock in the event of malicious attack, blocking the intruder thereby the magnets acting as a blocking pin, and the mechanical and/or electromagnetic energy of the attack is configured to move the hard magnet to seal the digital lock from the intruder.
