  Gas burner and method for controlling the sameUSPTO Application #: 20060078836Title: 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.

[0001] This application claims the benefit of Korean Application No. P2004-081260, filed on Oct. 12, 2004, and Korean Application No. P2004-081261, filed on Oct. 12, 2004, which are hereby incorporated by reference as if fully set forth herein. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a gas burner and a method for controlling the same, and more particularly, to a gas burner and a method for controlling the same in which stable use is possible and combustion efficiency is improved. [0004] 2. Background of the Related Art [0005] Generally, a gas burner is designed to generate heat for heating, cooking, and the like by burning gas fuel such as LPG and LNG. The gas burner is manufactured in various types depending on its purpose of use. [0006] Hereinafter, a related art gas burner will be described with reference to the accompanying drawings. [0007] FIG. 1 illustrates a related art gas burner, and FIG. 2 is a graph illustrating a temperature of a glass depending on operational time of the gas burner. [0008] Referring to FIG. 1 and FIG. 2, the related art gas burner includes a burner body 1 burning a mixture gas of gas fuel and air, a gas supplying valve 2 supplying the gas fuel to the burner body 1, and an air supplying fan 3 supplying the air to the burner body 1. [0009] A glass 7 is provided on the burner body 1. An object to be heated is laid on the glass 7. A mixing tube 4 is provided at one side of the burner body 1 and supplies the mixture gas to the burner body 1. [0010] A gas supplying tube 5 is provided at one side of the gas supplying valve 2 and serves as a path that supplies the gas fuel to the burner body 1. An air supplying tube 6 is provided at one side of the air supplying fan 3 and serves as a path that supplies the air to the burner body 1. [0011] The gas supplying tube 5 and the air supplying tube 6 are connected with the mixing tube 4, and the mixing tube 4 is connected with the burner body 1. Therefore, the air supplied through the air supplying fan 3 is supplied to the mixing tube 4 through the air supplying tube 6. The gas supplied through the gas supplying valve 2 is supplied to the mixing tube 4 through the gas supplying tube 5. Afterwards, the air and the gas supplied to the mixing tube 4 are mixed with each other in the mixing tube 4 and then supplied to the burner body 1. [0012] The mixture gas supplied to the burner body 1 generates heat while being burned. The glass 7 is heated by the generated heat and the object laid on the glass is heated. At this time, if the gas burner is operated at a constant air-fuel ratio, the temperature of the glass increases in proportion to the operational time. As shown in FIG. 2, after the lapse of predetermined time, the relation graph between the operational time and the temperature of the glass has a non-linear curve. [0013] Meanwhile, load given to the air supplying fan during the operation of the related art gas burner is not constant but revolution per minute (RPM) of the air supplying fan is constant regardless of time. [0014] For this reason, the following problems occur. [0015] If the air flow is excessively supplied, flame becomes unstable to fail to normally supply heat. If the air flow of small quantity is supplied, the mixture gas is imperfectly burned to increase the concentration of CO contained in exhaust gas. [0016] Since the related art burner is operated at a constant air-fuel ratio, the glass is overheated because no separate control device is provided if the temperature of the glass increases at a reference value or greater, thereby reducing stability. [0017] In addition, heat loss increases as the temperature of the glass increases at a reference value or greater. As a result, a room temperature increases and the concentration of CO contained in the exhaust gas increases. SUMMARY OF THE INVENTION [0018] Accordingly, the present invention is directed to provide a gas burner and a method for controlling the same that substantially obviates one or more problems due to limitations and disadvantages of the related art. [0019] An object of the present invention is to provide a gas burner and a method for controlling the same in which stable use is possible. [0020] Another object of the present invention is to provide a gas burner and a method for controlling the same in which combustion efficiency is improved. [0021] Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objectives and other advantages of the invention may be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings. [0022] To achieve these objects and other advantages and in accordance with the purpose of the invention, as embodied and broadly described herein, a gas burner according to the present invention includes 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.
