DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention will be more clear from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
A gas intake structure of the present invention is used in a gas stove, and the cooking part of the gas stove in accordance with present invention, as shown in FIG. 6, comprises: a sink 20, a rack 21, a burner 22, two intake pipes 23, two intake structures 24, and an intake valve 25. The rack 21 is detachably installed in the sink 20, the burner 22 is received in the sink 20, and the sink 20 is formed with a port (not numbered) for the burner 22. The two intake pipes 23 are installed in the burner 22 and extend out of the sink 20 via the port (not numbered). The two intake pipes 23 are connected to the two intake structures 24, and the two intake structures 24 are connected to the intake valve 25.
The embodiment of the present invention is shown in FIG. 7, wherein each of the intake structures 24 is a tubular-shaped and has an open end 241 and an output end 242. A through hole 243 is formed in either side surface of the intake structure 24. A plurality of air deflectors 244 is formed in each of the through holes 243 and is inclined toward the flow direction of the gas. A positioning hole 245 is formed in the open end 241 for positioning the intake valve 25, and the output end 242 is connected to the intake pipes 23.
For a better understanding of the embodiment, its operation and function, reference should be made to FIG. 8, gas A flows through the intake valve 25 into the intake structures 24 and is mixed with air B therein. Since the air deflectors 244 of the intake structures 24 are inclined toward the flow direction of the gas A, the air B will be forced by the flow of the gas A to flow through the through holes 243 and the air deflectors 244 and into the intake structures 24. The inclination angle of the air deflectors 244 allows air B to flow more smoothly, the air B intake volume, the flame of the gas stove, the mixture ratio of gas A to air B will be more stable, and as a result, the flame of the burner 22 will be stable.
The number of the through holes 243 in the side surfaces of the intake structure 24 can be one, two, three or more as desired. And both ends of the through holes 243 are also provided with the air deflector 244 for guiding the flow of the gas. The number of the intake structures 24 and the intake pipes 23 are not limited to two, and can also be one. The intake structures 24 and the intake pipes 23 can be made of hard or flexible material. The intake structures 24, the intake pipes 23, and the burner 22 can be integral with one another, as shown in FIG. 9.
The air deflectors 244 of the intake structures 24 are located at an angle of 35 degrees with respect to the vertical direction of the side surface of the intake structures 24. The angle of the air deflectors 244 with respect to the surface of the intake structures 24 ranges from 20 to 60 degrees.
To summarize, a gas intake structure for a gas stove in accordance with the present invention has a tubular shape, and both ends of the gas intake structure are connected to intake valve and intake pipes, respectively. At least one through hole is formed in side surface of the intake structure, and a plurality of air deflectors is formed in the through hole and is inclined toward the flow direction of the gas. The air deflectors allow the air to flow enter the intake structures more smoothly. As a result, the mixture ratio of gas to air is more stable, and the flame of the burner is also more stable.
While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
