Recirculating downdraft system for a cooking appliance
Provided is a cooking appliance that includes an oven cavity and an oven door pivotally mounted to a front surface and configured to selectively provide access to an interior of the oven cavity. A cooktop includes a heating element and an inlet of a downdraft system exposed at a top surface of the cooking appliance. An outlet is provided through which air drawn into the downdraft system through the inlet is exhausted to an ambient environment of a room in which the cooking appliance is located. An air duct system conveys air between the inlet and the outlet, and a blower draws air from the ambient environment of the cooking appliance adjacent to the cooktop into the inlet and through the air duct system to be expelled through the outlet back into the ambient environment.
1. A cooking appliance comprising:
an oven cavity;
an oven door pivotally mounted to a front surface and configured to selectively provide access to an interior of the oven cavity;
a cooktop including at least one heating element and a single inlet of a downdraft system, the cooktop defining a top surface of the cooking appliance;
an air duct system comprising a first air path for the air to flow between the single inlet and a first outlet and a separate, second air path for the air to flow between the single inlet and a second outlet; and
a blower configured to draw air from an ambient environment of the cooking appliance adjacent to the cooktop into the single inlet and through the air duct system to the first outlet and the second outlet, and to exhaust the air through a main outlet back into the ambient environment.
2. The cooking appliance of claim 1 , wherein the air duct system comprises a first plenum and a second plenum, wherein the first plenum extends along a first side surface in between the first side surface and the oven cavity, further wherein the second plenum extends along a second side surface in between the second side surface and the oven cavity.
3. A cooking appliance comprising:
an oven cavity;
an oven door pivotally mounted to a front surface and configured to selectively provide access to an interior of the oven cavity;
a cooktop defining a top surface of the cooking appliance and including at least one heating element and a single inlet of a downdraft system, an access member pivotally mounted to the cooktop and pivotable between a first position and a second position, wherein at the first position the access member conceals the single inlet, and at the second position the access member permits air to enter the single inlet;
an air duct system comprising a first air path for the air to flow between the single inlet and a first outlet and a separate, second air path for the air to flow between the single inlet and a second outlet; and
a blower configured to draw air from the ambient environment of the cooking appliance adjacent to the cooktop into the single inlet and through the air duct system to the first outlet and the second outlet, and to expel the air through a main outlet back into the ambient environment.
4. The cooking appliance of claim 3 , wherein the access member comprises a catch member configured to selectively prevent rotation of the access member beyond the second position to a third position, wherein at the third position, the access member provides access to the air duct system.
5. The cooking appliance of claim 3 , wherein the access member comprises a cover surface that extends over the single inlet at an angle relative to the top surface when the access member is in the second position.
6. The cooking appliance of claim 3 , wherein the access member comprises an opening that is elevated relative to the cooktop and permits the air to pass therethrough and enter the single inlet when the access member is in the second position.
7. The cooking appliance of claim 1 , further comprising an auxiliary door configured to selectively provide access to the air duct system, wherein the auxiliary door is movable between an open position and a closed position.
8. The cooking appliance of claim 7 , wherein the auxiliary door defines the main outlet.
9. The cooking appliance of claim 1 , wherein the main outlet is located below the oven cavity.
10. The cooking appliance of claim 1 , wherein the cooktop comprises a rear edge, a front edge, and a total number of heating elements, wherein the single inlet is adjacent the rear edge and the total number of heating elements are each located at least partially between the single inlet and the front edge.
11. The cooking appliance of claim 10 , wherein the cooktop comprises a centerline and the single inlet is arranged along the centerline.
12. A cooking appliance having a top surface, bottom surface, front surface, back surface, a first side surface, and a second side surface opposing the first side surface, the cooking appliance comprising:
an oven cavity;
an oven door pivotally mounted to the front surface and configured to selectively provide access to the oven cavity;
a cooktop including at least one heating element and an inlet, the cooktop defining the top surface of the cooking appliance;
a first outlet and a second outlet;
an air duct system configured to selectively provide air communication between the inlet and the first outlet and further configured to selectively provide air communication between the inlet and the second outlet; and
a blower configured to selectively draw air from an ambient environment of the cooking appliance into the inlet and through the air duct system and expel the air out the first outlet back into the ambient environment, the blower further configured to selectively draw the air from the ambient environment of the cooking appliance into the inlet and through the air duct system and expel the air out the second outlet.
