Gas burner and method for controlling the same

Abstract

Disclosed are a gas burner and a method for controlling the same in which stable use is possible and combustion efficiency is improved. The gas burner includes a burner body burned by a mixture gas of gas fuel and air, a gas supplying valve supplying the gas fuel to the burner body through a gas supplying tube connected with the burner body, an air supplying fan supplying the air to the burner body through an air supplying tube connected with the burner body, and a control part controlling air flow supplied to the burner body by controlling revolution per minute (RPM) of the air supplying fan. Since an optimal air-fuel ratio can be maintained by controlling the RPM of the air supplying fan, combustion efficiency can be increased. Since a temperature of a glass can be maintained properly, life span of the gas burner can be increased and its stable use is possible.

1 . A gas burner comprising: 
 a burner body burning a mixture gas of gas fuel and air;    a gas supplying valve supplying the gas fuel to the burner body through a gas supplying tube connected with the burner body;    an air supplying fan supplying the air to the burner body through an air supplying tube connected with the burner body; and    a control part controlling air flow supplied to the burner body by controlling revolution per minute (RPM) of the air supplying fan.    
   
   
       2 . The gas burner according to  claim 1 , further comprising at least one of a temperature sensor measuring a temperature of a glass provided on the burner body and a pressure sensor measuring inner pressure of the gas burner.  
   
   
       3 . The gas burner according to  claim 2 , wherein the temperature sensor is provided at the bottom of the glass.  
   
   
       4 . The gas burner according to  claim 3 , wherein the control part controls the RPM of the air supplying fan depending on the temperature of the glass measured by the temperature sensor.  
   
   
       5 . The gas burner according to  claim 1 , wherein the burner body includes a burner chamber in which the mixture gas is burned, a burner mat heated by burning the mixture gas, and a burner housing fixed to the burner chamber while pressurizing the edge of the burner mat.  
   
   
       6 . The gas burner according to  claim 2 , wherein the pressure sensor is provided in the air supplying tube that connects the burner body with the air supplying fan.  
   
   
       7 . The gas burner according to  claim 6 , wherein the control part controls the RPM of the air supplying fan depending on the pressure measured by the pressure sensor.  
   
   
       8 . A method for controlling a gas burner comprising: 
 a first step of measuring data for controlling RPM of an air supplying fan, which supplies air to the gas burner, using at least one of a temperature sensor and a pressure sensor provided at one side of the gas burner;    a second step of comparing the data measured in the first step with data previously set in the gas burner; and    a third step of controlling the RPM of the air supplying fan depending on the result of the second step.    
   
   
       9 . The method according to  claim 8 , wherein the third step includes increasing the RPM of the air supplying fan if the temperature measured by the temperature sensor is higher than the previously set data.  
   
   
       10 . The method according to  claim 8 , wherein the third step includes maintaining the RPM of the air supplying fan as it is if the temperature measured by the temperature sensor is lower than the previously set data.  
   
   
       11 . The method according to  claim 8 , wherein the third step includes decreasing the RPM of the air supplying fan if the pressure measured by the pressure sensor is higher than the previously set data.  
   
   
       12 . The method according to  claim 8 , wherein the third step includes increasing the RPM of the air supplying fan if the pressure measured by the pressure sensor is lower than the previously set data.
