In paragraph 1, The above fan module includes a fan that rotates to send hot air to the cooking chamber, and a fan motor that rotates the fan. The above fan motor includes a BLDC motor configured to rotate the fan at three or more different speeds, and In the above sabas mode, the fan motor rotates the fan at a speed lower than or equal to the third lowest speed among three or more types of speeds.
In paragraph 1, The heating device comprises a convection heater positioned adjacent to the fan module at the rear side of the cooking chamber, and a bake heater positioned at the lower side of the cooking chamber. A cooking device in which, in the above sabas mode, at least one of the convection heater and the fan module operates, and the bake heater does not operate.
In paragraph 1, The above fan module includes a fan that rotates to send hot air to the cooking chamber, and a fan motor configured to rotate the fan in the forward and reverse directions. In the above sabas mode, the fan motor is a cooking appliance in which the forward and reverse rotations of the fan are alternately operated.
A method for controlling a cooking device comprising a main body forming a cooking chamber and a heating device having a fan module that operates to send hot air to the cooking chamber, wherein Input verification step for verifying the input operation mode; and It includes an operation control step for controlling the operation of the fan module according to the type of input operation mode, and If the operation mode entered in the above input verification step is a normal operation mode, the above operation control step operates the fan module to either a first output or a second output lower than the first output, and A method for controlling a cooking device in which, if the operation mode entered in the above input verification step is a sabas mode, the above operation control step operates the fan module at a third output lower than the second output.
In paragraph 8, A control method for a cooking appliance in which, if the operation mode entered in the above input verification step is a sabbath mode, the operation of an input unit that generates a signal for manually operating at least one of the lighting and heating device implemented in the cooking appliance is deactivated.
In paragraph 8, A control method for a cooking appliance in which, if the operation mode entered in the above input verification step is a sabas mode, operation control for changing the operation of the cooking appliance is deactivated even if door opening/closing or input unit operation occurs.
In paragraph 8, The above fan module includes a fan that rotates to send hot air to the cooking chamber, and a fan motor that rotates the fan. If the operation mode entered in the above input verification step is a normal operation mode, the above operation control step operates the fan motor so that the fan rotates at either a first speed or a second speed lower than the first speed, and A method for controlling a cooking appliance in which, if the operation mode entered in the above input verification step is a sabbath mode, the above operation control step operates the fan motor so that the fan rotates at a third speed lower than the second speed.
In paragraph 8, The heating device comprises a convection heater positioned adjacent to the fan module at the rear side of the cooking chamber, and a bake heater positioned at the lower side of the cooking chamber. A method for controlling a cooking device in which, if the operation mode entered in the above input verification step is a sabas mode, the above operation control step operates at least one of the convection heater and the fan module without operating the bake heater.
In paragraph 8, The above fan module includes a fan that rotates to send hot air to the cooking chamber, and a fan motor configured to rotate the fan in the forward and reverse directions. If the operation mode entered in the above input verification step is a sabas mode, the above operation control step is a method for controlling a cooking appliance that operates the fan motor so that the forward and reverse rotations of the fan alternate.

Description

Cooking appliance and method for controlling thereof The present invention relates to a cooking appliance, and more specifically, to a cooking appliance that provides a Sabbath mode and a method for controlling the same. Cooking appliances are household appliances installed in a kitchen space to cook food according to the user's intentions. Such cooking appliances can be classified in various ways depending on the heat source or form used, or the type of fuel. When classifying cooking appliances according to the form in which food is cooked, they can be classified into open and closed types based on the shape of the space where the food is placed. Closed cooking appliances include ovens and microwave ovens, while open cooking appliances include cooktops, hobs, and griddles. A sealed cooking appliance is a cooking device that shields the space where food is placed and cooks the food by heating that shielded space. A sealed cooking appliance is provided with a cooking chamber, which is a space that is shielded when food is placed and cooked. This cooking chamber effectively becomes the space where the food is cooked. A sealed cooking appliance is provided with a rotatable door that selectively opens and closes the cooking chamber. The door is rotatably installed on the main body by means of a door hinge provided between the main body, which has a cooking chamber formed inside, and the door. By rotating the door around the part connected to the main body through the door hinge, the cooking chamber can be selectively opened and closed. A heat source is provided in the interior space of the cooking chamber, which is opened and closed by the above door, to heat the cooking chamber. A gas burner or an electric heater may be used as such a heat source. As an example, a broil burner or a grill heater may be installed on the upper side of the cooking chamber, and a bake burner or a bake heater may be installed on the rear or lower side of the cooking chamber. Additionally, a convection device may be further provided at the rear of the cooking chamber. The convection device is a device that performs the operation of circulating air inside the cooking chamber so that heat is evenly distributed throughout the entire cooking chamber. Such a convection device may include a fan cover installed on the rear wall of the cooking chamber and a convection fan installed in the internal space of the fan cover. An intake port and an exhaust port may be provided in the fan cover. Of these, the intake port may be formed in the center of the front of the fan cover facing the door, and the exhaust port may be formed on the side of the fan cover facing the side of the cooking chamber. The convection fan rotates inside the fan cover and can generate airflow. Through this convection fan, an air circulation flow can be created in which air from the cooking chamber is drawn into the fan cover through the intake port, and air heated inside the fan cover is discharged into the cooking chamber through the exhaust port.
