Method for controlling cleaning cooking appliance

A method for controlling cleaning of a cooking appliance, the cooking appliance including a cavity configured to accommodate food to be cooked, the cavity including a panel, a heater configured to heat an interior of the cavity, and a controller configured to control the heater, the method comprising:

• increasing an internal temperature of the cavity to a set first temperature and then to a set second temperature;
• and
• maintaining the internal temperature of the cavity at the second temperature,
• wherein the increasing the internal temperature includes:
• increasing the internal temperature of the cavity to the first temperature set lower than the second temperature;
• and
• increasing the internal temperature of the cavity to reach the second temperature from the first temperature,
• wherein a temperature increase rate inside the cavity in the increasing the internal temperature of the cavity to the first temperature is set higher than a temperature increase rate inside the cavity in the increasing the internal temperature of the cavity to reach the second temperature,
• wherein the heater includes a broil heater and a bake heater, and
• wherein, after the internal temperature of the cavity reaches the first temperature, an inner heater of the broil heater and the bake heater alternate outputting heat more frequently than after the internal temperature of the cavity reaches the second temperature.

A method for controlling cleaning of a cooking appliance, the cooking appliance including a cavity configured to accommodate food to be cooked, the cavity including a panel, an inner heater disposed at an upper portion of the cavity, an outer heater disposed at the upper portion of the cavity to surround the inner heater, the outer heater having a maximum heat output lower than a maximum heat output of the inner heater, and a bake heater configured to heat the panel, the method comprising:

• increasing an internal temperature of the cavity to a set first temperature and then to a set second temperature;
• and
• maintaining the internal temperature of the cavity at the set second temperature,
• wherein the increasing the internal temperature and the maintaining the internal temperature each include:
• operating the inner heater and the bake heater in a continuous alternating manner;
• and
• setting an operation time of the bake heater to be longer than an operation time of the inner heater,
• wherein the increasing the internal temperature includes:
• increasing the internal temperature of the cavity to the first temperature set lower than the second temperature;
• and
• increasing the internal temperature of the cavity to reach the second temperature from the first temperature,
• wherein a temperature increase rate inside the cavity in the increasing the internal temperature of the cavity to the first temperature is set higher than a temperature increase rate inside the cavity in the increasing the internal temperature of the cavity to reach the second temperature,
• wherein a broil heater includes the inner heater and outer heater, and
• wherein, after the internal temperature of the cavity reaches the first temperature, the inner heater of the broil heater and the bake heater alternate outputting heat more frequently than after the internal temperature of the cavity reaches the second temperature.
