Method for controlling heating apparatus

Abstract

Provided is a method for controlling a heating apparatus. A method for controlling preheating of a heating apparatus, in which a fuel tank and a fuel injection part are provided in a first passage that provides a moving path, and fuel remaining in the first passage moves in a second direction opposite to a first direction while preheating a fuel injection part, which injects the supplied fuel in the first direction, before ignition, includes a passage opening process of allowing the first passage to communicate with the outside through a discharge valve provided in the first passage, and a preheating process of heating at least a portion of the fuel injection part before the fuel injected from the fuel injection part is ignited.

What is claimed is: 
     
         1 . A method for controlling preheating of a heating apparatus, in which a fuel tank and a fuel injection part are provided in a first passage that provides a moving path, and fuel remaining in the first passage moves in a second direction opposite to a first direction while preheating a fuel injection part, which injects the supplied fuel in the first direction, before ignition, the method comprising:
 a passage opening process of allowing the first passage to communicate with the outside through a discharge valve provided in the first passage; and   a preheating process of heating at least a portion of the fuel injection part before the fuel injected from the fuel injection part is ignited.   
     
     
         2 . The method of  claim 1 , wherein the passage opening process and the preheating process are performed at the same time or at different times. 
     
     
         3 . The method of  claim 1 , wherein the heating apparatus comprises:
 a fuel pump;   a fuel inflow part provided downstream of the first passage from the fuel pump to allow the fuel tank and the fuel pump to communicate with each other; and   a fuel discharge part provided upstream of the first passage to guide discharge of the fuel of the fuel pump,   wherein the discharge valve is provided in the fuel discharge part.   
     
     
         4 . The method of  claim 1 , wherein the heating apparatus further comprises:
 a hot air discharge part configured to accommodate the fuel injection part and guide hot air generated by igniting the fuel injected from the fuel injection part to the outside; and   a blowing fan configured to introduce external air so as to move to the hot air discharge part,   wherein, while the passage opening process and the preheating process are performed, the method further comprises an external air supply process of supplying the external air by the blowing fan to a second passage provided so that the air moves from the blowing fan to the outside through the hot air discharge part.   
     
     
         5 . The method of  claim 1 , further comprising, while the passage opening process and the preheating process are performed, an igniter operation process of operating an igniter configured to ignite the fuel injected from the fuel injection part. 
     
     
         6 . The method of  claim 5 , further comprising a passage closing process of closing the discharge valve to prevent the first passage from communicating with the outside. 
     
     
         7 . The method of  claim 6 , wherein the igniter operation process and the passage closing process are performed at the same time or at different times. 
     
     
         8 . The method of  claim 7 , further comprising a fuel supply process of operating a fuel pump provided downstream of the first passage from the discharge valve to allow the fuel to move to the fuel injection part after the passage closing process.
