  • 2. Description of the Prior Art
  • Gas cannot combust without being mixed with Oxygen, therefore, the gas of a gas stove must be mixed with oxygen before ignition, otherwise, it cannot be ignited. A conventional gas stove is shown in FIG. 1, and the cooking part of the gas stove as shown in FIG. 2 comprises a sink 10, a rack 11, a burner 12, two intake pipes 13, two intake structures 14, and a intake valve 15. The rack 11 is detachably disposed at the entrance (not numbered), and the burner 12 is received in the sink 10. The sink 10 is formed with a port (not numbered) for the burner 12. The two intake pipes 13 are disposed on the burner 12 and extend out of the sink 10 via the port (not numbered). The two intake structures 14 and the two intake pipes 13 are connected to each other. The installation positions of the burner 12, the two intake pipes 13 and the two intake structures 14 are shown in FIG. 3. The two intake structures 14 are connected to the intake valve 15. The rough route that the gas takes is from the intake valve 15, via the two intake structures 14 and the two intake pipes 13, and then to the burner 12 for combustion. The intake structures 14 are the places where air enters and is mixed with the gas.
  • The conventional intake structures 14 include netted intake structure 16 and hole type intake structure 17. The netted intake structure 16, as shown in FIG. 4, has a tubular shape. Both ends of the netted intake structure 16 are connected to the intake valve 15 and the intake pipes 13, respectively. A separating net 161 is arranged on each side of the netted intake structure 16. When flowing through the two nets 161, the gas is mixed with air by the nets 161, so that the gas flowed through the netted intake structure 16 can be mixed with oxygen and will be ignited after being ejected out of the burner 12. However, the direction of air entering the netted intake structure 16 is vertical to the flowing direction of the gas, air cannot enter the netted intake structure 16 easily, as a result, air intake volume is unstable, and the mixture ratio of gas to air is also unstable. Accordingly, the flame of the gas stove is unstable. Besides, making two pieces of separating net 161 is troublesome and not cost saving.
  • The hole type intake structure 17, as shown FIG. 5, has a tubular shape. Both ends of the hole type intake structure 17 are connected to the intake valve 15 and the intake pipes 13, respectively. A plurality of intake holes 171 is annularly formed in the outer surface of the hole type intake structure 17. As compared with the netted intake structure 16, the hole type intake structure 17 is a unitary structure integrally formed with the intake holes without needing particularly to make the separating nets 161, and its cost is comparatively low. However, air is still unable to enter the hole type intake structure 17 easily, and the unstable mixture ratio of air to gas is still not solved.
  • The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
    • SUMMARY OF THE INVENTION
  • The primary objective of the present invention is to provide a gas intake structure for a gas stove, which allows air to flow more smoothly into the intake structure and to be mixed with the gas.
  • To obtain this objective, the tubular intake structure of the present invention is formed in either side surface thereof with a through hole, 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.
  • The secondary objective of the present invention is to provide a gas intake structure for a gas stove that can prevent the invasion of foreign objects.
  • In addition to guiding the flow of air, the plurality of air deflectors formed in the through hole can also prevent the invasion of foreign objects into the gas intake structure.

    •  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.
