Description

Detailed Description of the Invention

[0001]

The present invention relates to relates to a gas burner applied to Gascon B, more particularly hard boiled affected spill gas burner.

[0002]

2. Description of the Related Art The flame holes of a gas burner for a gas stove that has been conventionally used are provided on the upper surface or the inclined upper surface. As shown in FIG. 5, the gas burner 51 is cooked by putting a pan 53 through the Gotoku 52. When the pan is boiled, the contents spill out from between the pan lid 54 and the pan 53. Then, the spilled water, so-called boiled spill, travels along the outer surface of the pan 53 and hits the flame to extinguish the flame.
If the flame goes out, raw gas spouts out of the flame hole, creating a dangerous condition. In addition, a part of the flame hole is blocked by spillage, the flames of the gas become uneven, and there is an inconvenience such as partial boiling.

Further, the flame ejected from the flame holes goes straight upward, heats the bottom surface of the pan 53, and goes outward through the side surface of the pan. Therefore, the pan 53 and the combustion gas do not come into strong contact with each other, resulting in poor thermal efficiency.

[0006]

According to the present invention, the gas burner for the stove is formed in a ring shape, and the vertical inner peripheral surface is provided with flame holes. The upper surface of the ring is covered with a lid, and the lid projects inward from the inner peripheral surface of the ring. For this reason, even if spillage occurs, the water content of the spillage drips from the side of the pan onto the lid and is guided to the center of the ring from the lid, and the spillage does not reach the flame holes directly.

Further, according to the present invention, the flame holes are provided on the inner peripheral surface of the ring burner in the shape of a groove for ejecting gas at an angle of 30 to 60 ° with respect to the normal line direction of the inner peripheral surface. The combustion gas is applied at. This causes the combustion gas to collide violently with the cooking utensil, resulting in high thermal efficiency. The corner is 30
If it is less than 60 degrees, it is less effective, and if it is more than 60 degrees, there is a risk of blowing out. Particularly according to the invention, a ring-shaped burner head
The plurality of flame holes 6b formed in 5b are slit-shaped.
Are formed at equal intervals in the circumferential direction, and
It has an inclination of 30 to 60 with respect to the normal line 14 (see FIG.
), The shape is inclined with respect to the axis 13 of the burner head 5b.
Is generated (see FIG. 3 described later), and is therefore sprayed on the flame hole 6b.
It is formed by the mixture of secondary air with the injected mixed gas.
The flame is formed almost uniformly in the circumferential direction of the burner head 5b.
Therefore, a pan or the like can be heated uniformly.

EXAMPLES The present invention will be more specifically described below with reference to examples. FIG. 1 shows a gas burner 1 for a stove, which is a premise of the present invention.
2 is a cross-sectional view taken along the line II-II in FIG. In the ring-shaped gas burner 1, the fuel gas and the primary air are mixed in the mixing pipe 2, and the mixture enters into the ring-shaped second mixing pipe 3 in the tangential direction. The mixed gas is ejected toward the center of the ring from the flame hole 6 of the burner head 5 provided on the inner peripheral surface 4 of the second mixing pipe 3. When the mixed gas is ignited, the secondary air is directed to the burner along arrow 7 by the draft action.
The fuel gas is sucked inward on the inner peripheral surface of the pad 5, and the fuel gas burns.
The combustion gas further rises along the arrow 8 and heats the cookware 12 on the Gotoku 11. The upper surface of the burner head 5 has lid 9, the inner circumferential surface 10 of the lid 9 protrudes remote inwardly by the inner circumferential surface of the burner head 5. This is the pan 12
The spilled boiled off the sardine is transmitted to the inside of the ring from the inner peripheral surface 10 of the lid 9 along the side surface of the pan 12, and the spilled spill does not directly reach the burner head 5. The inner circumferential surface 10 of the cover 9 against the inner peripheral surface of the burner head 5, for example, 1m
It is protruding.

In this structure , the flame holes 6 of the burner head 5 are provided in a slit shape parallel to the axis 13 of the burner head 5.
However, in the embodiment of the present invention shown in FIG. 3, the burner head 5 having the slit-shaped flame holes 6b inclined with respect to the axis 13 is provided.
b is used .

[0010] direction of the burner ports 6 has a 30 to 60 ° inclination with respect to the normal of the circumferential circle towards the center of the burner head 6.
FIG. 4 shows the burner head 5 according to the section line IV-IV of FIG.
FIG. The flame holes 6 are arranged at equal intervals on the ring-shaped inner peripheral surface 4, for example, at intervals of 10 °, and the normal line 1 to the inner peripheral surface 4 of the ring.
36 pieces are provided at an angle of 30 ° with respect to 4. Mixed gas ejected from the burner ports 6 is ignited, collide with mixed gas jetted from adjacent burner ports 6, the ring center Sunawa
Then, a turbulent turbulent flow is formed toward the center of the burner head 5b, and the heating efficiency is increased by violent contact with the bottom surface of the cooking utensil 12 on the Gotoku 11 as well. Further, since the spiral swirling flow promotes the suction of the secondary air, high load combustion is possible even if the inner peripheral surface of the ring has a relatively small area. Further, when the stove is used under a low load, the gas ejection amount is small and the gas concentration is low, but a stable combustion state can be maintained even in such a state.

[0011]

As described above, according to the present invention, the spillage does not directly hit the flame holes of the gas burner for the stove, and the spillage extinguishes the gas to generate no raw gas. Further, according to the present invention, the gas becomes a swirling flow in the ring, and the thermal efficiency is increased. According to the invention, a plurality of burner heads 5b
The flame holes 6b are slit-shaped and are formed at equal intervals in the circumferential direction.
30 to 60 with respect to the normal line 14 of the inner circle toward the center
It has an inclination of ° and it is on the axis 13 of the burner head 5b.
Since it is formed so as to be inclined, a uniform flame is formed in the circumferential direction.
The pan can be heated uniformly.
