Description

Cooking apparatus and method of controlling cooking apparatus The present disclosure relates to a cooking appliance and a method for controlling the cooking appliance. Generally, a cooking appliance is a device that cooks food by being equipped with a cooking chamber, a heating device that applies heat to the cooking chamber, and a circulation fan that circulates the heat generated by the heating device within the cooking chamber. Cooking appliances are devices that cook food by sealing and heating it, and they can generally be classified into electric, gas, and electronic types based on their heat source. Electric ovens utilize electric heaters as a heat source, while gas ovens and microwave ovens utilize heat generated by gas and frictional heat from water molecules caused by high frequency, respectively. Generally, a cooking appliance comprises a main body that forms the exterior and has an open front, forming a cooking chamber into which food to be cooked is placed, and a door installed on the front of the main body to selectively open and close the cooking chamber. The door is composed of multiple glass panels to prevent heat from inside the cooking chamber from being released to the outside. Since the door's temperature rises due to the heat inside the cooking chamber, an air intake is provided in the door to draw in outside air in order to prevent the door's temperature from rising. The air drawn in through the air intake circulates through an air passage provided between the multiple glass panels to lower the temperature of the air, and then is discharged to the outside of the door. Generally, to lower the surface temperature of the outside of the door, high-temperature air inside the door is expelled to the outside of the door by a cooling structure utilizing the Venturi effect, or high-temperature air inside the door is forcibly sucked in and expelled to the outside of the door by a cooling fan. The present disclosure provides a cooking appliance and a method for controlling the cooking appliance, which can open and close a discharge hole of a door duct that discharges high-temperature air inside the door to the outside of the door according to the temperature of the cooking chamber. The technical problems to be solved in this document are not limited to those mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art to which this invention belongs from the description below. A cooking device according to one embodiment of the present disclosure may include: a main body; a cooking chamber provided inside the main body so as to have its front open; a door for opening and closing the cooking chamber; a door duct including a discharge hole for discharging air inside the door to the outside of the door; and a control unit that opens the discharge hole based on the temperature inside the cooking chamber being above a preset temperature, and closes the discharge hole based on the temperature inside the cooking chamber being below the preset temperature. A control method for a cooking appliance according to one embodiment of the present disclosure may include: detecting the temperature inside a cooking chamber; opening a discharge hole of a door duct that discharges air inside a door to the outside of the door based on the fact that the temperature inside the cooking chamber is above a preset temperature; and closing the discharge hole based on the fact that the temperature inside the cooking chamber is below the preset temperature.
