Description

Technical Field

[0001] This invention relates to a combustion device, particularly a combustion device with high combustion efficiency. Background Technology

[0002] Please refer to the Taiwan Patent No. I306498, "Improved Structure of Gas Burner Outlet Pipe", which is a gas burner outlet pipe. It is an outlet pipe with a first end and a second end. The first end has an air inlet to allow gas to enter. The outlet pipe has several small holes and several air inlets. The diameter of the air inlets is larger than that of the small holes. The small holes allow the flame to burst out when the gas is burning, and the air inlets allow fresh air to enter.

[0003] Reference Figure 5 The diagram shows a partially enlarged cross-sectional view of the outlet pipe of an existing gas burner. In addition to the air inlet in the middle and rear section, the outlet pipe 90 of the above-mentioned burner also needs to be equipped with a main mixing port 91 for air to enter. However, the main mixing port 91 of the conventional gas burner is located at the lower edge of the outlet pipe 90 in the vertical direction. This is mainly to prevent the juice produced during the grilling process from dripping into the outlet pipe 90 through the mixing port 91. However, this arrangement also causes the gas flow rate in the outlet pipe to drop rapidly due to the bending of the pipe, which in turn affects the air intake effect of the outlet pipe and leads to a decrease in combustion efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a combustion device with high combustion efficiency, thereby solving at least one of the aforementioned technical problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A combustion device with high combustion efficiency, characterized in that it comprises:

The air mixing cover and the second side form an air passage. The two ends of the air passage along the axial direction of the baseline are open.

[0012] The X-axis and the Y-axis form a rectangular coordinate system, and the intersection of the X-axis and the Y-axis forms an origin. The first curved section is located in the second quadrant of the rectangular coordinate system of the X-axis and the Y-axis.

The third bend is located in the third quadrant of the rectangular coordinate system of the X-axis and the Y-axis. The center of the bend arc of the third bend is located on the side of the third bend adjacent to the origin.

The first mixing port 312 is disposed on the second side 314. The exhaust section 32 is connected to one end of the mixing section 31 opposite to the intake port 311. The exhaust section 32 is provided with a straight section 321 and a first curved section 322. The straight section 321 extends along the baseline L-axis and one end is connected to the mixing section 31. One end of the first curved section 322 is connected to one end of the straight section 321 opposite to the mixing section 31, and the other end extends away from the mixing section 31 and toward the Y-axis.

[0024] The burner tube 30 is connected to a gas nozzle 40, which is inserted into the mixing section 31 through the air inlet 311. A second mixing port 315 is formed between the inner periphery of the mixing section 31 and the outer periphery of the gas nozzle 40. The second mixing port 315 is open at one end opposite to the gas outlet section 32.

[0025] The burner tube 30 is provided with a mixing cover 33. One side of the mixing cover 33 is connected to the upper edge of the mixing section 31 in the vertical direction and the other side is connected to the lower edge of the mixing section 31 in the vertical direction. The mixing cover 33 covers but does not close the first mixing port 312.

[0026] The air inlet 311 protrudes from the base 20. One end of the air mixing cover 33 along the axial direction of the baseline L is disposed inside the base 20 and the other end protrudes from the base 20. The air mixing cover 33 and the second side 314 form an air channel 331. The two ends of the air channel 331 along the axial direction of the baseline L are respectively open.

[0027] The X-axis and the Y-axis form a rectangular coordinate system, and the intersection of the X-axis and the Y-axis forms an origin O. The first curved portion 322 is located in the second quadrant of the rectangular coordinate system of the X-axis and the Y-axis. The center of the curved arc of the first curved portion 322 is located on the side of the first curved portion 322 adjacent to the origin O. The air outlet section 32 is provided with a second curved portion 323. One end of the second curved portion 323 is connected to the end of the first curved portion 322 opposite to the straight portion 321. The second curved portion 323 is located in the first quadrant of the rectangular coordinate system of the X-axis and the Y-axis. The center of the curved arc of the second curved portion 323 is located on the side of the second curved portion 323 adjacent to the origin O.

[0028] The air outlet section 32 is provided with a third curved section 324. One end of the third curved section 324 is connected to the end of the second curved section 323 opposite to the first curved section 322. The third curved section 324 is located in the third quadrant of the rectangular coordinate system of the X-axis and the Y-axis. The center of the curved arc of the third curved section 324 is located on the side of the third curved section 324 adjacent to the origin O. The radius of the curved arc of the third curved section 324 is smaller than the radius of the curved arc of the first curved section 322 and the radius of the curved arc of the second curved section 323.

[0029] The air outlet section 32 is provided with a straight pipe section 325. One end of the straight pipe section 325 is connected to the end of the third bend section 324 opposite to the second bend section 323. The straight pipe section 325 extends in a straight line along a direction parallel to the X-axis toward the straight passage section 321. The end of the straight pipe section 325 opposite to the third bend section 324 is closed.

[0030] The combustion device 10 improves combustion efficiency through the aforementioned structure. Gas can enter the burner tube 30 through the air inlet 311. The negative pressure generated by the gas flow rate draws air in through the first mixing port 312 and the second mixing port 315. After the gas mixes with the air, it flows to the straight section 321. Because the opening direction of the first mixing port 312 and the bending direction of the first curved section 322 are on the same side of the mixing section 31, the air and gas can flow smoothly along the shape of the first curved section 322 after mixing, reducing the velocity loss of gas and air flowing in the burner tube 30. This also avoids reducing the initial velocity of the gas in the mixing section 31, allowing the mixing section 31 to introduce more air and improve combustion efficiency.
