Description

가스곤로용 버너{A burner for gas stove}Burner for gas stove {A burner for gas stove}

본 발명은, 버너본체에 화구홈을 갖는 버너헤드를 재치하여 화구를 형성하는 형식의 곤로용 버너에 관한 것이다.The present invention relates to a furnace burner of a type in which a burner head having a crater groove in a burner body is mounted to form a crater.

종래의 가스곤로용 버너는, 약한 불로 줄였을 때의 화력이 0.465KW(400㎉/h)정도이고, 이 때문에 화력을 약하게 하면 불꽃이 꺼지거나 가스분배실측으로 불꽃이 되돌아오는 역화현상(逆火現象)이 생기는 일이 있다. 도 5는, 약화(弱火)시의 보염성을 개선하여 역화의 방지를 의도한 종래의 버너헤드의 일례를 나타낸 것(일본국 특공소 평4-61246호)으로, a는 버너헤드, b는 가스분배로, c는 화구홈형성부이고, 그 내주측에 내주돌기(d)를 설치하고, 외주측에 내주돌기(d)와 위상을 엇갈리게 외주돌기(e)를 설치하며, 내주돌기(d,d) 사이에 내주측통로(d1)를 형성하고, 외주돌기(e,e) 사이에 화구홈(e1)를 형성하며, 외주돌기(e)의 단면(端面)에 얕은 보조화구홈(e2)을 설치한다. 이 버너헤드(a)는, 내주측통로(d1)와 화구홈(e1)이 비직선상에 있기 때문에 통과저항이 커서, 그 때문에 가스공급량이 과잉일 때는, 유출속도를 제어하고, 또 가스공급량을 작게 줄였을 때는, 불꽃이 화살표(f)방향으로 반대로 되는 것을 방지할 수 있어, 가스의 최저공급량을 작게 할 수 있다고 되어 있다. 또, g는 내측 화구이다.The conventional burner for gas stove has a fire power of 0.465 KW (400 kW / h) when it is reduced to low heat. Therefore, if the fire power is reduced, the flame turns off or the flame returns to the gas distribution chamber. I) may occur. Fig. 5 shows an example of a conventional burner head intended to improve flame resistance at the time of weakening and to prevent backfire (JP-A 4-61246), where a is burner head and b is By gas distribution, c is a crater groove forming part, and an inner circumferential protrusion (d) is installed on the inner circumferential side thereof, and an outer circumferential protrusion (e) is installed on the outer circumferential side with the inner circumferential protrusion (d) alternately arranged, The inner peripheral passage (d 1 ) is formed between the, d), the crater groove (e 1 ) is formed between the outer peripheral protrusions (e, e), and the auxiliary crater grooves shallow in the cross section of the outer peripheral protrusion (e) Install (e 2 ). This burner head (a) has a large passage resistance because the inner circumferential side passage (d 1 ) and the crater groove (e 1 ) are in a non-linear fashion, so that when the gas supply amount is excessive, the outflow rate is controlled. When the gas supply amount is reduced, the flame can be prevented from being reversed in the direction of the arrow f, and the minimum supply amount of gas can be reduced. G is an inner crater.

그러나, 이 버너헤드(a)에 있어서는, 홈형성부(c)에 전체 가장자리에 걸쳐내주돌기(d)와 외주돌기(e) 2열의 돌기를 설치하기 때문에, 구조가 복잡하고, 소경(小經)의 버너헤드에 적용하는 것은 치수면에서 문제점이 있었다. 또한, 화구홈(e1) 모두가 감속작용을 가지기 때문에, 불꽃의 강약의 변화량을 크게 할 수는 없다.However, in this burner head (a), because the groove forming portion (c) is provided with two rows of inner circumferential protrusions (d) and outer circumferential protrusions (e) over the entire edge, the structure is complicated, and the small diameter Application to the burner head of a) has been problematic in terms of dimensions. In addition, since all the crater grooves e 1 have a deceleration action, the amount of change in the intensity of the flame cannot be increased.

본 발명은, 간단한 수단으로 종래보다, 화력을 줄인 경우의 버너의 보염성을 높히고, 동시에 역화현상을 방지할 수 있는 버너를 얻는 것을 과제로 한다.An object of the present invention is to obtain a burner capable of increasing the flame resistance of the burner in the case of reducing the thermal power by simple means and at the same time preventing backfire.

상기한 과제를 해결하기 위한 수단은, 청구항 1항에 기재한 바와 같이, 버너헤드에 가스분배로와 화구홈형성부를 링형상으로 내외 이중으로 설치하고, 화구홈형성부에 다수의 화구홈을 방사형상으로 설치하며, 상기 화구홈형성부를 버너 본체의 링형상의 받침면에 재치하여 양부분에 의해 화구를 형성한 가스곤로용 버너에 있어서, 상기 화구홈과 깊이가 거의 동일하고 상기 화구홈보다 홈폭이 크고 길이가 짧은 보염화구홈를, 버너헤드의 화구홈형성부의 여러 부분에 설치하여, 상기 보염화구홈 내주에 중간의 격벽으로 분기된 수 개의 좁은 유입홈을 연설한 것을 특징으로 한다.Means for solving the above problems, as described in claim 1, the gas distribution path and the crater groove forming portion in the ring shape in the burner head, the inside and outside of the ring shape, and radiates a plurality of crater grooves in the crater groove forming portion A gas furnace burner having a shape and having the crater groove forming part mounted on a ring-shaped support surface of a burner main body, wherein the crater is formed by both portions, the depth of which is substantially the same as that of the crater groove, and the groove width is greater than that of the crater groove. The large and short flameproof groove is installed in various parts of the burner groove forming portion of the burner head, and the several narrow inflow grooves branched into the middle partition wall in the inner flameproof groove are characterized by speech.

이 버너에 있어서, 가스를 줄여 약화로 하였을 때, 보염화구이외의 화구의 연소가 불안정하게 되려고 해도, 보염화구의 불꽃이 안정하기 때문에, 상기 보염화구로부터 다른 화구로 불꽃이동되어 연소가 안정화한다. 또한, 약화되었을 때 보염화구내에서 역화현상이 생기려고 해도, 보염화구내의 격벽이 역화의 저항이 되어 역화를 억제한다.In this burner, when the gas is reduced and weakened, even if the combustion of the fireball other than the flame burner is unstable, the flame of the flame burner is stable, and the flame is moved from the flame burner to the other fireball to stabilize the combustion. . In addition, even when the backfire occurs in the flame burner when weakened, the partition wall in the flame burner becomes a resistance to backfire and suppresses the backfire.

발명의 실시형태Embodiment of the invention

이하, 도면을 참조하여 본 발명의 실시 형태를 설명한다. 도 1, 도 4에 있어서, 1은 버너헤드, 2는 버너본체이고, 양자에 의해 버너(B)가 구성된다. 버너헤드(1)는, 도1∼도3에 도시한 바와 같이 중앙의 감합통(3) 주위에 링형상의 가스분배로(4)와 화구홈형성부(5)가 내외이중으로 설치되어 있다. 화구홈형성부(5)는, 하향의 링형상의 부분을 가지며, 상기 부분에 종래의 버너헤드와 마찬가지로 깊은 화구홈(6)과 얕은 보조화구홈(7)이 방사방향으로 설치되고, 일부에 점화부(8)가 설치된다. 화구홈형성부(5)에는, 상기 점화부(8)부분을 제외하고 거의 등간격으로 여섯 개의 보염화구홈(10)이 설치되어 있다.EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described with reference to drawings. 1 and 4, 1 is a burner head, 2 is a burner main body, and the burner B is comprised by both. As shown in Figs. 1 to 3, the burner head 1 is provided with a ring-shaped gas distribution passage 4 and a crater groove forming portion 5 around the fitting tube 3 in the center. . The crater groove forming portion 5 has a downward ring-shaped portion, in which the deep crater groove 6 and the shallow auxiliary crater groove 7 are radially installed, as in the conventional burner head. An ignition section 8 is provided. In the crater groove forming unit 5, six flame-retardant crater grooves 10 are provided at substantially equal intervals except for the ignition unit 8 portion.

보염화구홈(10)의 홈폭은 W, 길이는 L로서 표시되며, 홈폭(W)은 화구홈(6) 폭의 2∼3배이고, 길이(L)는 화구홈(6) 길이의 거의 반이다. 보염화구홈(10)의 내주측에는 격벽(11)을 끼워 두 개의 유입홈(12,12)이 형성된다. 도면 중에서 13은, 버너(B)의 중심공에 하방으로부터 삽입되는 도외(圖外)의 온도센서에 대한 보호통이다.The groove width of the flameproof groove 10 is expressed as W, the length is indicated as L, the groove width W is two to three times the width of the crater groove 6, and the length L is almost half the length of the crater groove 6. . Two inflow grooves 12 and 12 are formed on the inner circumferential side of the flame retardant groove 10 by sandwiching the partition wall 11. In the figure, 13 is a protective cylinder with respect to the outside temperature sensor inserted from below into the center hole of burner B. As shown in FIG.

도 4에 도시한 바와 같이, 버너헤드(1)를 종래에 통상적으로 이용되고 있는 버너본체(2)에 취부하여 버너(B)를 구성하면, 가스분배로(4)는 버너본체(2)의 유도로(14)와 공동으로 분배실(4A)을 형성하고, 화구홈(6), 보조화구홈(7), 보염화구홈(10) 및 유입홈(12)은 버너본체(2)의 받침면(15)과 공동으로 화구(6A),보조화구(7A), 보염화구(10A) 및 유입구(12A)를 형성한다.As shown in FIG. 4, when the burner head 1 is attached to the burner body 2 which is conventionally used, and the burner B is comprised, the gas distribution path 4 of the burner body 2 is carried out. A distribution chamber 4A is formed jointly with the induction furnace 14, and the crater groove 6, the auxiliary crater groove 7, the flame burner groove 10, and the inlet groove 12 support the burner body 2. The crater 6A, the auxiliary crater 7A, the flame extinguisher 10A, and the inlet 12A are jointly formed with the face 15.

이 버너(B)의 보염화구(10)에 있어서는, 홈폭(W)이 크기 때문에, 화구출구주변의 가장자리부의 길이가 길어져, 이로써 보염성이 향상된다. 또한, 길이(L)가 짧아 보염화구(10A)내의 통과저항이 적기 때문에, 가스밸브를 조작했을 때의 화염의 변화가 완화되어, 급격히 약화조작을 하더라도 소화하지 않게 된다. 더욱이, 약화성능이 향상되어 조리품의 보온성이 좋게 된다. 상기 보온성을 확실히 하기 위한 보온테스트는, 직경 20㎝의 알루미늄 냄비에 1000㎖의 물을 넣어 중불에서 끓이고, 약화에서 5분간 보지하며, 이 때의 중량을 초기중량으로 하고 약화를 계속하여 1시간 후의 증발량을 조사하는 테스트로, 테스트가스 13A-1, 가스압 2.0㎪의 조건에서 최소화력 0.29㎾(250㎉/h)의 버너에 의해 이루어졌다.In the flame retardant tool 10 of this burner B, since the groove width W is large, the length of the edge part of the flame outlet periphery becomes long, and a flame retardance improves by this. In addition, since the length L is short and the passage resistance in the flame burner 10A is small, the change of the flame when the gas valve is operated is alleviated, and the fire is not extinguished even if the abrupt operation is abruptly performed. Moreover, the weakening performance is improved, and the warmth of the cooked food is improved. Insulation test to ensure the heat retention, put 1000ml of water in a 20cm diameter aluminum pot, boil at medium heat, hold for 5 minutes in weakening, the weight at this time as the initial weight and continued weakening after 1 hour The test for checking the evaporation amount was performed by a burner having a minimum force of 0.29 kPa (250 kPa / h) under the test gas 13A-1 and gas pressure of 2.0 kPa.

종래의 버너에 있어서는, 최소 0.465㎾(400㎉/h)에서 증발량 180g인 것에 비해, 도시한 버너(B)에 있어서는, 화력을 0.29㎾(250㎉/h)로도 줄일 수 있고 이 화력에서 증발량은 70g이었다. 이 테스트에 있어서, 증발량은 61% 감소하였고, 화력은 37.5% 감소하였다. 이와 같이, 화력의 감소량에 비해 증발량의 감소량이 큰 것은 약화에서의 수분의 증발이 적어, 끓임 또는 보온에 적합하다라는 것이다.In the conventional burner, the thermal power can be reduced to 0.29 kPa (250 kW / h) in the burner B shown in comparison with the evaporation rate of 180 g at the minimum of 0.465 kPa (400 kPa / h). It was 70 g. In this test, the amount of evaporation decreased 61% and the thermal power decreased 37.5%. In this way, the larger amount of evaporation is lower than the reduced amount of thermal power is that evaporation of moisture in the weakening is small and suitable for boiling or warming.

또한, 상기 0.29㎾(250㎉/h) 전후로 줄여도, 화살표(f)로 나타낸 바와 같은 역화현상은 모두 생기지 않았다. 이것은 격벽(11)에 의해 역류에 대한 저항이 생긴 것에 기인한다고 이해할 수 있다.Moreover, even if it reduced to around 0.29 kPa (250 kPa / h), all the backfires as shown by the arrow f did not generate | occur | produce. It can be understood that this is due to the occurrence of resistance to backflow by the partition 11.

또한, 상기 버너는 보조화구(7A)를 가지는 것이지만, 보조화구가 없는 버너에 있어서도 같은 작용이 생긴다.The burner has an auxiliary crater 7A, but the same action occurs in the burner without the auxiliary crater.

이상의 설명으로 명확한 바와 같이, 보염화구로서 다른 화구에 비해 깊이는 거의 동일하고 홈폭이 크며 길이가 짧은 보염화구를 설치함으로써, 상기 보염화구의 화구출구주변의 가장자리부의 길이가 길어져 보염성이 향상하며, 상기 보염화구의 길이가 짧기 때문에, 통과저항이 적어져, 이로써 불꽃의 변화가 완화되어 급격한 화력조작을 하더라도 소화되지 않고, 유입구측 격벽의 저항에 의해 역화현상이 방지되는 효과가 있다. 또한, 상기 보염화구를 버너의 여러 부분에 설치하였기 때문에, 보염작용이 확실히 이루어지는 이점이 있다.As is clear from the above description, by providing a flame-proofing tool having a depth that is substantially the same as other fireballs, having a larger groove width and a shorter length, the length of the edge portion around the fire outlet of the flame-proofing tool is improved, thereby improving flame resistance. In addition, since the length of the flame burner is short, the passage resistance is reduced, thereby reducing the change in the flame, even if a rapid fire operation is not extinguished, there is an effect that the backfire phenomenon is prevented by the resistance of the inlet side partition wall. In addition, since the flame-retaining tool is provided in various parts of the burner, there is an advantage that the flame-retardant action is surely performed.
