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 door latch module for a self-cleaning oven comprising:
- a support adapted to be mounted to the self-cleaning oven;
- a motor maintained on said support;
- a latching mechanism maintained by said support and driven by said motor;
- a plurality of switches maintained on said support;
- and
- a plurality of terminals associated with said plurality of switches, said plurality of terminals configured to connect to a single terminal interface.
A door latch for a self-cleaning oven comprising:
- a support adapted to be mounted to a self-cleaning oven;
- a cam maintained by said support;
- a cam plate coupled to said cam and driven by said cam;
- a motor coupled to said cam and operative to drive said cam;
- a latch mechanism coupled to and driven by said motor;
- a plurality of switches maintained on said support and selectively actuated by said cam plate;
- and
- a plurality of terminals associated with said plurality of switches and maintained on said support, said plurality of terminals ganged to permit connection to a single terminal interface.
In a self-cleaning oven having door hingedly attached to a frame, and a controller operative to control the self-cleaning oven, a door latch mechanism comprising:
- a support coupled to the frame proximate the door;
- a rotating cam maintained by said support;
- a motor coupled to said rotating cam and operative to drive said rotating cam;
- a cam plate coupled to said rotating cam and driven by said rotating cam;
- a latch mechanism coupled to and driven by said motor, said latch mechanism driven by said motor to lock the door during a locking mode and to allow free movement of the door during a non-locking mode;
- a plurality of switches maintained on said support;
- and
- a plurality of terminals associated with said plurality of switches and maintained on said support, said plurality of terminals ganged to permit connection to a single point terminal connector.
