20140175079 | CONTROL OF COOKING APPLIANCE IN RESPONSE TO CONTROL-COMPARTMENT, COOLING FAN FAILURE - A control system for a control-compartment cooling fan of an oven. In one embodiment, the control system includes a sensor for sensing an operating condition of a motor of the cooling fan. The operating condition is selected from the group of a motor current and a motor RPM. A controller is communicatively connected to the sensor and is configured to receive the operating condition from the sensor, compare the operating condition to one or more predetermined tolerances and, when the operating condition exceed at least one of the one or more predetermined tolerances, generate an interrupt command. A heating control element is communicatively connected to the controller and configured to interrupt operation of a heating element in response to receiving the interrupt command. The control system may also include a user interface communicatively connected to the controller. | 06-26-2014 |
20130186387 | SELF-CLEANING OVEN - A conveyor oven having a first mode of operation and a second mode of operation is provided. The conveyor oven generally includes an oven chamber in which food is cooked, a conveyor movable to convey the food through the oven chamber, a burner to generate heat for the oven chamber, at least one blower to circulate air within the oven chamber, and a controller. The burner has a combustion airflow rate, and operates at a first output during the first mode of operation and at a second output that is greater than the first output during the second mode of operation. The blower operates at a first speed during the first mode of operation and at a second speed that is faster than the first speed during the second mode of operation. The controller is responsive to at least one of a burner output and an internal temperature of the oven chamber, and increases the speed of the blower from the first speed during the first mode of operation to the second speed during the second mode of operation responsive to at least one of an increase of the burner output and an increase of the internal temperature of the oven chamber. | 07-25-2013 |
