Abstract
A door latching or locking mechanism or module for a self-cleaning oven includes latching linkage of the door latch module that enables use of lighter duty, less expensive motor. The mechanical advantage and vector optimization of the latching linkage avoids stalling especially from a locked position. The latching mechanism includes a plurality of switches having a corresponding plurality of terminals. The terminals are grouped or ganged to allow connection with a single connector interface. The switches are selectively actuable/de-actuable by a cam and cam plate that utilizes linear motion translated from rotational motion of a driven (motor) to selectively actuate and/or de-actuate the switches.
Claims20
A latch mechanism for a self-cleaning oven comprising:
- a support;
- a reciprocating cam maintained by said support;
- a motor coupled to said reciprocating cam and operative to drive said reciprocating cam;
- a latch mechanism coupled to said motor and driven by said motor;
- a plurality of switches maintained by said support;
- and
- a cam plate coupled to said reciprocating cam and driven by said reciprocating cam, said cam plate operative to actuate selective switches of said plurality of switches during cam plate motion.
A latch mechanism for a self-cleaning oven comprising:
- a support;
- a rotatable cam maintained by said support;
- a motor coupled to said rotatable cam and operative to drive said rotatable cam;
- a latch mechanism coupled to said motor and driven by said motor;
- a plurality of switches maintained by said support;
- and
- a cam plate maintained by said support, said cam plate coupled to and driven by said rotatable cam so as to undergo linear translation during cam rotation, said cam plate operative to actuate selective switches of said plurality of switches during cam plate linear translation.
In a self-cleaning oven having a door hingedly attached to a frame, and a controller operative to control the self-cleaning oven, a door latch mechanism comprising:
- a support;
- a reciprocating cam maintained by said support;
- a motor coupled to said reciprocating cam and operative to drive said reciprocating cam;
- a latch mechanism coupled to said motor and driven by said motor;
- a plurality of switches maintained by said support;
- and
- a cam plate coupled to said reciprocating cam and driven by said reciprocating cam, said cam plate operative to actuate and de-actuate selective switches of said plurality of switches during cam plate motion.
