A latching assembly uses a flat sheet metal chassis with electrical switches, an electrical motor driving a cam, a push rod, a hook, a spring, and various actuators/levers. When a first actuator/lever is moved by an outside force, a circuit connection may be opened or closed depending upon the configuration of the electro-mechanical system. This will generate a signal which will allow current to flow to a motor. The motor will, in turn, drive the cam which will push a second actuator/lever to move and cause a hook to move from a first, non-latching position to a second, latching position. The assembly is useful for latching an oven or other appliance door when operating at high temperature. 1. A latching apparatus suitable for use with an appliance door having a proximal end and a distal end and movable between a non-latching state and a latching state , the latching apparatus comprising:a chassis which houses at least one electrical switch, an electrical motor driving a cam, a door switch actuator having a proximal end and a distal end, a latch hook, and a flexible printed circuit;wherein when the latching apparatus is in the non-latching state:a. the proximal end of the door switch actuator is in a first position with respect to the electrical switch and the distal end of the door switch actuator is in corresponding first position wherein the position of proximal end of the door switch actuator with respect to the electrical switch, results in an open or closed electrical circuit with the electrical switch, andb. the latch hook is in a non-latching position wherein the proximal end of the latch hook is engaged with the cam, the cam being in contact with but not activated by the switch, andwherein when the latching apparatus is in the latching state:a. the proximal end of the door switch actuator is in a second position with respect to the electrical connector and the distal end of the door switch actuator is in a corresponding second position wherein:b. the door ...

An apparatus for latching a door having a latching member; a retention cam wherein the retention cam further comprises an extended face and is rotatable about its axis; a spring; a locking member; an actuator; a push out member; and a driving member; wherein the actuator drives the driving member to remove the locking member from contact with the retention cam and the driving member drives the push out member to push the latching member away from the retention cam. The apparatus is capable of assisting both in the latching and unlatching of the device. 1. An apparatus for latching a door comprising:a latching member;a retention cam wherein the retention cam further comprises an extended face and is rotatable about its axis;a locking member;an actuator;a push out member; and 'wherein the actuator drives the driving member to remove the locking member from contact with the retention cam and the driving member drives the push out member to push the latching member away from the retention cam.', 'a driving member;'}2. The apparatus of claim 1 , wherein the latching member is able to travel over the locking member.3. The apparatus of further comprising a spring.4. The apparatus of claim 3 , wherein the spring is capable of limiting the rotation of the retention cam.5. An apparatus for latching a door comprising:a locking member;a retention member;a pivoting cam wherein the pivoting cam is rotatable about its axis;a solenoid; and 'wherein the solenoid rotates the retention member to release the lock member and drive the lock member away from the retention member.', 'a push out member;'}6. An apparatus for latching a door comprising:a latching member;a locking member;at least two magnets;a means for housing the at least two magnets;a spring;an actuator; and 'wherein the magnetic force between the at least two magnets is able to drive the latching member away from the locking member.', 'a pivoting cam wherein the pivoting cam is rotatable about its axis;'}7.

APPLIANCE LOCK WITH REPELLING MAGNETIC SENSING SWITCH ACTUATION IN A HYDROPHOBIC ENCLOSURE

Номер: US20200115923A1
Автор: DeYoung Roger, Lin I-Chiang
Принадлежит: HTI Technology and Industries, Inc.

Provided is a locking mechanism for a consumer appliance comprising a lid or door position sensing feature incorporating two magnets in a repelling relationship. One magnet is incorporated into a lid pawl and the other magnet is incorporated into a switch actuating component inside of the locking mechanism such that their like poles are facing each other to repel each other when the pawl is moved into the actuation zone of the locking mechanism. By nature, magnets tend to seek attraction alignment, therefore a repelling alignment is contrary to the natural tendency of magnets. Structural rigidity is required in the locking mechanism to hold the magnets in the repelling state. Consequently, it is not easy or intuitive for a user to defeat this sensing method with another magnet. 1. An appliance lock comprising:a lid pawl as a latch for a lid of an appliance, for restricting movement of the lid of the appliance, wherein the lid pawl receives and retains a lid pawl repelling magnet;a sliding switch actuator configured for sliding back and forth in a reciprocal motion, wherein the sliding switch actuator receives and retains a switch actuator repelling magnet, such that the lid pawl repelling magnet and the switch actuator repelling magnet are configured with like poles in a facing relationship to repel each other when the lid pawl is moved into an actuation zone; anda lid switch including a lid switch button, wherein magnetic repulsion from the two like poles of the respective switch actuator repelling magnet and the lid pawl repelling magnet facing each other moves the sliding switch actuator into an actuation position with the lid switch button, thus completing the circuit for appliance operation, thereby allowing the appliance to operate.2. The appliance lock of claim 1 , further comprising a circuit board assembly upon which the lid switch is mounted and within which the sliding switch actuator is configured for sliding back and forth in a reciprocal motion.3. The ...

Provided is a locking mechanism incorporating a cost-effective, non-contact lid or door sensing switch that is housed in a hydrophobically sealed enclosure. The lid or door position sensing feature is quiet in operation. The lid or door position sensing switch and the lock position sensing switch both carry high electrical power without the need for additional electrical components. The design also incorporates a spring-loaded lid or door pawl or a breaking pawl that protects the latch from catastrophic failure from a force open event making the appliance inoperable after the occurrence of such an event, thus requiring either the user (or a technician) to replace the pawl in order to operate the appliance. 1. An appliance lock comprising: 'a pawl bracket and a pawl arm comprising at least one protruding arm-like structure which extends away from the pawl bracket; and', 'a pawl mechanism acting as a latch for a lid of an appliance, for restricting movement of the lid of the appliance, wherein the pawl mechanism comprises a locking pin for engaging with the pawl arm of the pawl mechanism to thereby retain the pawl mechanism against movement;', 'a solenoid for displacing a solenoid plunger upon receipt of a momentary activation signal, wherein the solenoid plunger is connected to the locking pin such that as the solenoid plunger is extended, the locking pin is extended, moving the locking pin into a locked position for engaging and restricting the pawl arm, and wherein as the solenoid plunger is retracted, the locking pin is retracted so that the pawl arm can pass freely through an area occupied by the locking pin when in the extended position., 'a lock mechanism for engaging the pawl mechanism and thereby retaining the lid of the appliance in a closed state, wherein the lock mechanism comprises2. The appliance lock of claim 1 , wherein the lock mechanism further comprises a labyrinth block for limiting motion of the solenoid plunger to a locked state or unlocked state ...
