Cooking appliance and method for controlling cooking appliance

Abstract

A cooking appliance and a method for controlling the cooking appliance. The cooking appliance comprises: a main body forming a cooking chamber; a burner arrangeable inside the main body to heat the inside of the cooking chamber by burning gas fuel; a gas guide device which is mountable on the main body, including a gas inlet to allow an external gas supply line to supply gas fuel from an external gas source to be connected from an outside of the cooking chamber, and to supply the burner with the gas fuel introduced through the gas inlet; a temperature sensor which is arrangeable adjacent to the gas inlet outside the cooking chamber and detect ambient temperature of the gas inlet; and a controller electrically connectable to the burner and the temperature sensor to control the burner to stop the burning of the gas fuel based on the ambient temperature of the gas inlet being equal to or greater than a preset temperature.

1 . A cooking appliance comprising:
 a main body defining a cooking chamber;   a burner, arrangeable in the main body, configured to heat an inside of the cooking chamber by burning gas fuel;   a gas guide device, mountable on the main body, including:
 a gas inlet configured to allow an external gas supply line configured to supply the gas fuel from an external gas source to be connected from an outside the cooking chamber, and configured to supply the gas fuel from the external gas supply line to the burner to heat the inside of the cooking chamber by burning the gas fuel; 
   a temperature sensor, arrangeable from the outside of the cooking chamber to be adjacent to the gas inlet, to detect ambient temperature of the gas inlet; and   a controller, electrically connectable to the burner and the temperature sensor, configured to control the burner to stop burning the gas fuel based on the ambient temperature of the gas inlet being equal to or greater than a preset temperature.   
     
     
         2 . The cooking appliance of  claim 1 , further comprising:
 a detection circuit which includes the temperature sensor, and   wherein the temperature sensor is configured to switch the detection circuit to have a current flow through the detection circuit based on the ambient temperature of the gas inlet being less than the preset temperature and stop the current flow through the detection circuit based on the ambient temperature of the gas inlet being equal to or greater than the preset temperature.   
     
     
         3 . The cooking appliance of  claim 2 , wherein the controller is electrically connected to the detection circuit, and is configured to control the burner to stop burning the gas fuel based on the current flow through the detection circuit being stopped. 
     
     
         4 . The cooking appliance of  claim 1 , further comprising:
 a speaker electrically connectable to the controller,   wherein the controller is configured to control the speaker to output a sound in relation to an error occurrence based on the ambient temperature of the gas inlet being equal to or greater than the preset temperature.   
     
     
         5 . The cooking appliance of  claim 1 , further comprising:
 a display electrically connected to the controller,   wherein the controller is configured to control the display to display a notification in relation to an error occurrence based on the ambient temperature of the gas inlet being equal to or greater than the preset temperature.   
     
     
         6 . The cooking appliance of  claim 1 , further comprising:
 a communication module configured to communicate with an external terminal device and be electrically connectable to the controller,   wherein the controller is configured to control the communication module to transmit information in relation to an error occurrence to the external terminal device based on the ambient temperature of the gas inlet being equal to or greater than the preset temperature.   
     
     
         7 . The cooking appliance of  claim 1 , wherein the temperature sensor is located above the gas inlet. 
     
     
         8 . The cooking appliance of  claim 1 , wherein the gas guide device further comprises:
 a main gas supply line mountable on the main body and connectable to the burner to supply the gas fuel to the burner, and   a connector arrangeable outside the cooking chamber, connectable to the main gas supply line, and having the gas inlet arranged at the connector, and   wherein the temperature sensor is arranged to be adjacent to the connector.   
     
     
         9 . The cooking appliance of  claim 1 , further comprising:
 a supporter arranged outside the cooking chamber and configured to support the temperature sensor.   
     
     
         10 . The cooking appliance of  claim 9 , wherein the supporter comprises:
 a coupler coupleable to the main body, and   a sensor support portion to support the temperature sensor.   
     
     
         11 . The cooking appliance of  claim 10 , wherein:
 the sensor support portion is located above the gas inlet, and   the temperature sensor is settled on a top surface of the sensor support portion.   
     
     
         12 . The cooking appliance of  claim 9 , further comprising:
 a connector configured to be connectable to the external gas supply line outside the cooking chamber,   wherein the supporter covers at least one side of the connector.   
     
     
         13 . The cooking appliance of  claim 1 , wherein the main body comprises:
 a rear panel on which the gas guide device is mountable, and   a rear cover to cover at least a portion of the rear panel from outside, and   wherein the temperature sensor is arranged between the rear panel and the rear cover and covered by the rear cover.   
     
     
         14 . The cooking appliance of  claim 1 , wherein:
 the burner comprises an ignition configured to generate spark in the gas fuel,   the ignition is electrically connectable to the controller, and   the controller is configured to control the ignition not to generate spark based on the ambient temperature of the gas inlet being equal to or greater than the preset temperature.   
     
     
         15 . A method for controlling a cooking appliance including a burner to heat an inside of a cooking chamber, the method comprising:
 controlling the burner to heat the inside of the cooking chamber by burning gas fuel supplied through a gas inlet connected to an external gas supply line from an outside the cooking chamber; and   stopping the burner from burning the gas fuel based on ambient temperature of the gas inlet being equal to or greater than a preset temperature.
