Active venting control system

A ventilation system for a cooking appliance, comprising:

• an internal support defining a cooking cavity;
• an upper wrapper disposed proximate to the internal support, the upper wrapper at least partially defining a venting channel;
• a venting assembly coupled to the upper wrapper, wherein the venting assembly includes:
• a chimney in fluid communication with the venting channel via a vent opening, wherein the venting channel is in fluid communication with the cooking cavity via the vent opening and the chimney;
• an actuator;
• an actuator shaft operably coupled to the actuator;
• a linkage operably coupled to the actuator shaft;
• a cam defining a first groove and a second groove;
• a cover operably coupled to the actuator shaft, wherein the actuator is configured to drive rotation of the actuator shaft, which, consequently, causes rotation of the cover relative to the vent opening to open and close the vent opening;
• and
• a link coupled to the linkage via a connector, wherein the rotation of the actuator shaft causes rotation of the linkage along the cam, and wherein the rotation of the linkage causes rotation of the link via the connector, and wherein the rotation of the link causes rotation of the cover relative to the vent opening;
• and
• a controller communicatively coupled with the venting assembly, wherein the controller is configured to activate the venting assembly to open the vent opening.

A ventilation system for a cooking appliance, comprising:

• an internal support defining a cooking cavity;
• an upper wrapper disposed proximate to the internal support, the upper wrapper at least partially defining a venting channel in fluid communication with the cooking cavity via a vent opening defined in the upper wrapper and a chimney;
• a venting assembly coupled to the upper wrapper, wherein the venting assembly includes:
• a solenoid valve operable between an activated state and a deactivated state;
• a cover disposed proximate to the solenoid valve, wherein the cover includes a cover plate disposed over the vent opening and an end segment offset from the vent opening and operably coupled with the upper wrapper, and wherein the cover includes a fulcrum arm extending from the cover plate and coupled to the upper wrapper;
• and
• a controller communicatively coupled to the venting assembly, wherein the controller is configured to adjust the solenoid valve to the activated state to vertically move the cover relative to the vent opening to open the vent opening, and wherein when the solenoid valve is in the deactivated state the cover plate engages the vent opening and the end segment is at an oblique angle relative to a top surface of the upper wrapper.
