  Conventionally, as an ignition configuration in this type of gas stove, as shown in FIG. 11, in the gas stove 50 having the stove burner 51, the stove burner 51 has a main flame port 53 arranged on the circumference on the upper surface of the burner body 52. The burner cap 55 having the ignition flame port 54 disposed on a part of the circumference is placed, and the main flame port 53 and the ignition flame port 54 are combusted with the combustion flame 56 and the ignition flame 57 for cooking and heating. It was. In the stove burner 51, the burner cap 55 and the burner body 52 constitute an ignition space 59 in which an ignition electrode 58 is provided, the burner cap 45 facing the ignition electrode 58 constitutes a discharge target 60, and the gas stove 50 performs an ignition operation. If it does, it will be the structure which discharges between the ignition electrode 58 and the discharge target 60, and is the gas stove 50 comprised by the ignition flame opening 54 opening in the ignition space 59 (for example, refer patent document 1).

  However, in the configuration of Patent Document 1, the main flame port 53 is provided on the circumference to form the combustion flame 56, and the ignition flame port 54 is provided on the same circumference to form the ignition flame 57. In both cases, a flame is formed and burns toward the outer periphery of the stove burner 51. Therefore, when heating an object to be heated such as a pan for cooking on the gas stove 50, the center portion of the object to be heated is not heated because the combustion flame 56 or the like is not present, and the outside of the object to be heated is being heated. High-temperature combustion gas flows while heating the side surface from the outer periphery of the bottom surface of the object to be heated. In this way, the combustion gas flows along the outer periphery of the bottom surface of the object to be heated, so that the handle etc. existing on the side surface of the object to be heated becomes high temperature, making it difficult to touch directly, and inconvenience on the cooking work surface Had. In order to prevent the temperature of the handle or the like from becoming too high, a stove as shown in Patent Document 2 in order to provide a safe gas stove 50 by lowering the temperature of the combustion gas that has flowed to the side of the object to be heated. A burner 51 was provided.

In the gas stove 50 equipped with the stove burner 51, since the combustion flame is formed at the center of the object to be heated and heated, the temperature of the combustion gas when reaching the side surface of the object to be heated is the same as that of the object to be heated. Since the heat exchange between the two is low, the temperature of the handle of the object to be heated is low, so that a safe gas stove can be provided. A combustion confirmation flame port 65 is provided on a side surface 64 facing the secondary air passage hole 68 provided in the center of the burner 51 to heat the thermoelectric element 66. When combustion starts at the main flame port 53, the flame is Since the combustion is continued in a state where a swirl flow is generated by flowing obliquely upward along the line, the secondary air around the flame supplied to the flame 67 similarly exhibits a swirl flow state and flows into the flame 67. It is out. Accordingly, since the swirling flow of air is also generated in the region where the combustion confirmation flame port 65 is formed, the flame 67 of the combustion confirmation flame port 65 is blown away by the swirl flow under the influence of the surrounding swirl flow. As a result, there was a problem that a problem of extinguishing the fire occurred.

  Further, when cooking is performed by putting a cooked product into the heated object with the gas stove 50, if the broth or the like spills from the heated object, it spills on the burner cap 55 provided with the flame outlet 65. Since there is no guide or flow restriction for this spill, it flows freely to the flaming port 65, so that the flaming port 65 becomes clogged and combustion does not continue at the flaming port 65, and the heated object is not heated. In addition, there is a problem in that an unusable stove is provided in which the combustion load of the flame outlet 65 is increased, a blow-off phenomenon occurs as a combustion state, or a blow-off phenomenon occurs and the combustion is stopped.

  The present invention proposes a burner in which all the flame openings are formed on the upper surface side of the burner cap in order to solve the above-described conventional problems, shortens the distance from the bottom of the pan, and improves the thermal efficiency by heating uniformly. In particular, in the configuration where the upper surface of the burner cap is uneven and the flame outlet is provided, stable combustion, stable ignition performance, stable extinction safety performance are ensured, and energy saving and thermal efficiency are improved. The purpose is to provide an inexpensive gas stove that is easy to manufacture in terms of manufacturing.

  In order to solve the above-mentioned problems, a gas stove according to the present invention has an annular head having an opening on the upper surface, and a burner body that mixes the supplied gas and combustion air, and the annular head of the burner body can be attached and detached. A flame mouth A having a cross-sectional shape with one end projecting upward from the other end face of the projection provided with a concave projection on the upper surface of the mounting is arranged radially toward the center to form a main flame mouth portion. A gas burner cap is composed of a burner cap that has a concave portion that is larger than the center side of the concave portion A and is inclined toward the outer peripheral side. The ignition electrode and the extinguishing safety device thermoelectric element are provided outside the burner cap. It constitutes a combustion part.

According to the above invention, the flame mouth A having a cross-sectional shape in which one end protrudes upward from the other end surface of the convex portion provided with the concave convex portion on the upper surface of the burner cap that is detachably attached to the annular head of the burner body. A gas stove composed of a burner cap that is arranged radially toward the center side to form a main flame mouth, and the recess between the flame mouths A is made larger than the center side and inclined toward the outer periphery. A burner is mounted on the gas stove. When you start using this gas stove, while cooking the gas supplied from the burner body at the main flame opening and heating the object to be heated, the soup of the food in the object to be heated is spilled. When a phenomenon occurs, the simmered juice falls to the side of the object to be heated or directly to the upper surface of the burner cap. This boiled boiled spilled juice flows over the upper surface of the burner cap. Since this flow flows from the convex part to the concave part which becomes the bottom as compared with the convex part, the concave part serves as a flow path of the flow, and the concave part is inclined to the outer peripheral side of the burner cap. It flows to the outer periphery of. Therefore, as long as the broth spilled from the object to be heated does not spill directly into the flame outlet, the flame mouth will not clog, so when the combustion occurs due to an increase in the flame load due to clogging of the flame mouth. Therefore, a stable combustion state is maintained because there is no blow-off phenomenon or blow-out phenomenon of the combustion flame. Therefore, the normal phenomenon is maintained without causing any abnormality in the gas supply at the time of ignition to the ignition electrode part provided outside the burner cap or the combustion flame for heating the thermoelectric element of the extinguishing safety device provided at the same position. Is done. Furthermore, by providing a flame opening in the convex part and providing a concave part on both sides of the flame outlet, the concave part becomes a flow path against spillage from the object to be heated, etc. By tilting outward, the spillage is prevented from flowing into the gas stove from the opening on the upper surface of the gas stove burner, so that a stable and safe gas stove can be provided.

  Further, since the gas from the radial flame mouth formed on the upper surface of the burner cap is ejected obliquely upward with a speed, the gas is ejected in a swirling flow, and the combustion flame formed at the flame mouth Exhibits swirl combustion. Therefore, when the object to be heated is heated by swirling combustion, the combustion gas is forced to be stirred by the swirling flow, so that a turbulent flow state occurs. Since the turbulent combustion gas flows on the surface of the object to be heated, the temperature boundary layer generated between the surface of the object to be heated and the combustion gas is thinned, so that the heat transfer coefficient between the object to be heated and the combustion gas is increased. Therefore, the amount of heat transferred from the combustion gas to the object to be heated increases. A gas stove equipped with the above-described stove burner can provide an energy-saving gas stove with high thermal efficiency.

  In addition, the swirling flow causes the swirling phenomenon induced by the swirling flow in the air around the swirling flow, so the diffusion coefficient between the combustion flame and the secondary air for combustion increases during combustion, and the combustion Sufficient secondary air is supplied to the flame to achieve complete combustion. This complete combustion can provide a safe gas stove that does not generate carbon monoxide or the like.

  In addition, a flame mouth A having a cross-section with one end projecting upward from the other end surface is provided at equal circumferential intervals toward the center of the burner cap, and a planar portion is provided at both ends of the flame mouth portion to provide a flame mouth dimension. It has a shape that reduces the variation in the size, and is configured so that it can be fully pressed, including the flame opening, which makes it easy to manufacture and inexpensive.

  In addition, the main flame mouth part has a swirling flow due to the force that blows out in the circumferential direction and the force that exhaust heat is further exhausted from the upper direction through the bottom of the pan, resulting in a secondary secondary in the center. More secondary air can be sucked than the air passage hole, and good combustion can be obtained. Furthermore, the bottom of the pan and the burner can be brought closer to each other, and energy saving and thermal efficiency can be improved.

  The gas stove of the present invention provides an easy-to-use gas stove that has a reliable ignition performance that is resistant to spilling of boiled juice with energy saving with improved thermal efficiency, can perform stable combustion detection without extinction, and is easy to use Can do.

  A first invention has an annular head having an opening on the upper surface, a burner body for mixing the supplied gas and combustion air, a detachable attachment to the annular head of the burner body, and a concave protrusion on the upper surface. A flame opening A having a cross-sectional shape with one end projecting upward from the other end face is radially arranged toward the center side of the provided convex part to form a main flame mouth part, and the concave part between the flame mouths A is on the center side The gas burner cap is composed of a burner cap that has a larger amount of recesses and is inclined toward the outer periphery, and a central hole in which the burner cap enters in the center with the ignition electrode and the thermoelectric element of the safety device on the outside of the burner cap. A burner cap is disposed in the central hole of the ring-shaped covering body in which a space portion having an opening A and an opening B is formed on the flame A side and the lower side, and an ignition electrode is disposed in the space portion of the covering body. In the space on the cover facing the ignition electrode Constitute the discharge target the site is characterized in that to constitute a combustion unit.

As a result, the gas from the radial flame mouth formed on the upper surface of the burner cap is ejected at a speed obliquely upward, so that a swirl flow is formed and the gas is ejected, and the combustion formed in the flame mouth The flame exhibits swirl combustion. Therefore, when the object to be heated is heated by swirling combustion, the combustion gas is forced to be stirred by the swirling flow, so that a turbulent flow state occurs. Since the turbulent combustion gas flows on the surface of the object to be heated, the temperature boundary layer generated between the surface of the object to be heated and the combustion gas is thinned, so that the heat transfer coefficient between the object to be heated and the combustion gas is increased. Therefore, the amount of heat transferred from the combustion gas to the object to be heated increases. A gas stove equipped with the above-described stove burner can provide an energy-saving gas stove with high thermal efficiency.

  Further, a flame outlet A having a cross-sectional shape in which one end protrudes upward from the other end surface of the convex portion provided with the concave convex portion on the upper surface of the burner cap that is detachably attached to the annular head of the burner body is directed toward the center side. The main flame mouths are formed radially at regular intervals around the circumference, and the recesses between the flame mouths A are composed of burner caps that are inclined to the outer circumference side with a larger amount of recesses than the center side. When the gas stove is installed on the gas stove, when the gas stove is used, the gas supplied from the burner body is burned at the main flame opening to heat the object to be heated. When a phenomenon occurs in which the broth or the like of the cooked food in the product spills, the boiled juice falls on the side of the object to be heated or directly on the upper surface of the burner cap. This boiled boiled spilled juice flows over the upper surface of the burner cap. Since this flow flows from the convex part to the concave part which becomes the bottom as compared with the convex part, the concave part serves as a flow path of the flow, and the concave part is inclined to the outer peripheral side of the burner cap. It flows to the outer periphery of. Therefore, as long as the broth spilled from the object to be heated does not spill directly into the flame outlet, the flame mouth will not clog, so when the combustion occurs due to an increase in the flame load due to clogging of the flame mouth. Therefore, a stable combustion state is maintained because there is no blow-off phenomenon or blow-out phenomenon of the combustion flame. Therefore, the normal phenomenon is maintained without causing any abnormality in the gas supply at the time of ignition to the ignition electrode part provided outside the burner cap or the combustion flame for heating the thermoelectric element of the extinguishing safety device provided at the same position. Is done. Furthermore, by providing a flame opening in the convex part and providing a concave part on both sides of the flame outlet, the concave part becomes a flow path against spillage from the object to be heated, etc. By tilting outward, the spillage is prevented from flowing into the gas stove from the opening on the upper surface of the gas stove burner, so that a stable and safe gas stove can be provided.

  Further, a covering body provided with a space portion having an opening A having one end opened to the flame opening A side and an opening B having the other end opened to the lower side outside the flame opening is disposed outside the burner cap, An ignition electrode is included in the portion, a discharge target from the ignition electrode is formed in the space portion, a discharge space portion is provided between the ignition electrode and the discharge target to constitute an ignition portion, and a burner cap facing the discharge space portion is formed. On the outer peripheral wall, an ignition flame port portion having a cross-section in which one end protrudes from the other end surface and an ignition flame port portion arranged so as to face each other is formed, so that the gas ejected from the flame port on the upper surface of the burner cap is oblique Since it is ejected at a speed upward, it exhibits a swirling flow. A part of the swirling flow swirls out of the outer diameter of the burner cap due to the centrifugal force generated by the swirling flow outside the burner cap. Further, the gas ejected from the flame mouth B and the flame mouth C collides in the discharge space and exists as a collision flow. Therefore, a part of the swirling flow swirling outside the outer diameter of the burner cap flows into the space formed by the outer peripheral wall of the burner cap and the covering and coexists with the collision flow. When discharging from the ignition electrode toward the discharge target in a state where such a swirl flow and a collision flow are generated, there is a gas flowing in the swirl flow and a gas flowing in the collision flow reliably in the discharge space. It is ignited and combustion starts. In addition, since the ignition electrode is covered with a covering that forms a space, the soup may become wet or dirty even if boiled juice splatters or spills during cooking from the object to be heated. Therefore, it is possible to provide an easy-to-use gas stove by reliable ignition because the electric discharge is surely performed without causing electrical leakage. In addition, when the upper surface of the burner cap provided with the flame outlet A changes for some reason, for example, even if a situation occurs in which unevenness is generated due to adhesion of cooked food or the like and the swirl flow is not normally formed, the collision flow is generated. Since it exists in the discharge space, it is possible to provide an easy-to-use gas stove by reliable ignition.

According to a second aspect of the present invention, there is provided an ignition flame in which a flame mouth B and a flame mouth C having a cross section in which one end protrudes from the other end surface between the recesses of the burner cap on the outer peripheral wall of the burner cap facing the ignition electrode. The mouth portion is configured.

  Thereby, the flame outlet A having a cross-sectional shape in which one end protrudes upward from the other end surface of the convex portion provided with the concave convex portion on the upper surface of the burner cap that is detachably attached to the annular head of the burner body is provided at the center side. A gas stove burner comprising an ignition flame mouth portion composed of a flame mouth B and a flame mouth C on the outer peripheral wall of the burner cap corresponding to a space between the flame mouths A, which is radially arranged toward the front. When the use of this gas stove is started, the gas supplied from the burner body is burned at the main flame opening to heat the object to be heated. When a phenomenon occurs in which the soup of the cooked food or the like spills, the boiled soup falls on the side of the object to be heated or directly on the upper surface of the burner cap. This boiled boiled spilled juice flows over the upper surface of the burner cap. Since this flow flows from the convex part to the concave part which becomes the bottom as compared with the convex part, the concave part serves as a flow path of the flow, and the concave part is inclined to the outer peripheral side of the burner cap. Since the ignition flame mouth part composed of the flame mouth B and the flame mouth C provided between the recesses that become the flow path does not exist on the extension line of the flow path, it will not be clogged with boiled juice . Therefore, there is no clogging of the flame outlet B and the flame outlet C unless the broth spilled from the heated object is directly spilled into the flame outlet B and the flame outlet C. Therefore, there is no ignition failure due to the absence of gas in the discharge space during ignition. Therefore, it is possible to provide a gas stove that is stable and safe and easy to use.

  In addition, since there is no phenomenon that clogs flame mouth B and flame mouth C, the area of the flame mouth does not decrease. As a result, a stable combustion state is maintained. Therefore, the gas supply abnormality at the time of ignition to the ignition electrode portion provided outside the burner cap does not occur, and the normal phenomenon is maintained, so that a stable and safe gas stove can be provided.

  Further, in the stove burner that is ignited by the above-described ignition configuration and forms a swirling main flame on the upper surface of the burner cap, a flame outlet D having a cross-section with one end projecting from the other end surface at an appropriate position on the outer peripheral wall of the burner cap. And a flame outlet E facing each other, forming a thermoelectric element heating part, jetting the mixed gas supplied from the burner body to form a collision flame, and disappearing at a substantially middle part between the flame mouth D and the flame mouth E By arranging the thermoelectric element of the safety device, gas is ejected from the flame outlet D in the circumferential direction of the outer periphery of the burner cap, and the circumferential direction in the direction opposite to the gas ejected from the flame outlet D from the flame outlet E To erupt. Therefore, the gas ejected from the flame port D and the gas ejected from the flame port E are in a flow state of colliding at a substantially intermediate portion between the flame port D and the flame port E. Therefore, when combustion is started at the flame mouth D and the flame mouth E, a flame formed at the time of combustion forms a collision flame between the flame mouth D and the flame mouth E.

  At the same time, a swirl flow is presented at the flame opening A, and the combustion is continued and a swirl flow of secondary air is generated around the burner, so that the impinging flame is also blown away because it is formed in the swirl flow. The swirl flow acts as shown above, but the gas from the flame outlet D is jetted in the direction opposite to the jet direction from the flame mouth E. Thus, the collision flame continues without being blown away, and the thermoelectric element of the safety device disappears stably and is heated by the collision flame. Accordingly, it is possible to provide a stove with good usability that does not cause a problem of disappearing during use.

  The third aspect of the invention is a thermoelectric element heating in which a flame outlet D and a flame outlet E having a cross-section in which one end protrudes from the other end surface between the recesses of the burner cap on the outer peripheral wall of the burner cap facing the thermoelectric element. The portion is formed.

Thereby, the flame mouth A having a cross-sectional shape in which one end protrudes upward from the other end surface of the convex portion provided with the concave convex portion on the upper surface of the burner cap that is detachably attached to the annular head of the burner body.
Are arranged radially toward the center side to form a main flame mouth portion, and a thermoelectric element heating portion composed of a flame mouth D and a flame mouth E on the outer peripheral wall of the burner cap corresponding to the space between the recesses between the flame mouths A By installing the configured gas stove burner on the gas stove, when the use of this gas stove is started, the gas supplied from the burner body is burned at the main flame outlet and the object to be heated is being heated. When a phenomenon occurs in which boiled juice such as cooked food in the heated object is spilled, the boiled juice falls on the side of the heated object or directly on the upper surface of the burner cap. This boiled boiled spilled juice flows over the upper surface of the burner cap. Since this flow flows from the convex part to the concave part which becomes the bottom as compared with the convex part, the concave part serves as a flow path of the flow, and the concave part is inclined to the outer peripheral side of the burner cap. Since the ignition flame mouth part composed of the flame mouth D and the flame mouth E provided between the recesses which become the flow path does not exist on the extension line of the flow path, it will not be clogged with boiling juice . Therefore, there is no clogging of the flame outlet D and the flame outlet E unless the broth spilled from the heated object is directly spilled into the flame outlet D and the flame outlet E. Therefore, the non-heating state of the thermoelectric element due to the extinguishing of the collision flame at the time of use does not occur, so that the safety device does not operate to shut off the gas supply. Therefore, it is possible to provide a gas stove that is stable and safe and easy to use.

  In addition, since there is no phenomenon that clogs the flame mouth D and the flame mouth E, the area of the flame mouth does not decrease. As a result, a stable combustion state is maintained. Therefore, it is possible to provide a stable and safe and easy-to-use gas stove because the normal phenomenon is maintained without causing abnormal gas supply to the flame outlet D and flame outlet E of the thermoelectric elements provided outside the burner cap. is there.

  According to a fourth aspect of the present invention, the flame mouth B and the flame mouth C that form the ignition flame mouth, the flame mouth D and the flame mouth E that form the thermoelectric element heating part, the flame mouth surface formed by projecting one end from the other end surface In addition to providing a flat portion, a flame facing each other along the outer peripheral wall surface of the burner cap is formed.

  As a result, the flame outlet B and the flame outlet C provided with a flat portion on the flame front surface constitute the ignition flame mouth portion, and the flame outlet D and the flame outlet E provided with a flat portion on the flame mouth surface constitute the thermoelectric element heating portion. Since it comprises, the flow direction of the gas to eject is controlled, so gas is ejected in the tangential direction of the outer periphery of the burner cap along the parallel part. Therefore, the collision flame obtained by jetting from both flame outlets has a collision point near the outer periphery of the burner cap, so a negative pressure region is formed between the collision point and the outer wall of the burner cap, and the Coanda effect is more stable. An ignition collision flame and a collision flame are obtained. Therefore, since the normal phenomenon is maintained, it is possible to provide a stable and safe gas-operated gas stove.

  Further, when pressing, the flat part is applied to the mold, and the flame opening B and the flame opening C having a slit width dimension with little variation are obtained.

  5th invention provides the flame mouth F which ejects mixed gas in the direction different from the ejection direction of the flame mouth B and the flame mouth C between the flame mouth B and the flame mouth C which form an ignition flame mouth part, Alternatively, a flame port G for jetting a mixed gas in a direction different from the jet direction of the flame port D and the flame port E is provided between the flame port D and the flame port E forming the thermoelectric element heating unit, and both flame ports F And one or both of the flame mouth G are provided.

  As a result, the ignition collision flame formed along the outer peripheral wall of the burner cap and a flame is formed and burned outward from the outer peripheral wall of the burner cap at a substantially middle portion of the collision flame. The total amount of gas in the mouth and the thermoelectric element heating section is increased, each flame volume is increased, ignition is further ensured, and at the same time, heating of the thermoelectric element is further ensured, and at the same time, an ignition electrode, a discharge target, or a thermoelectric element Even if the positions are slightly shifted due to assembly variations, a large amount of gas is secured, so that stable performance can be obtained.

  In addition, even when the gas supply pressure to the burner is reduced when the gas stove is used, even if the combustion amount changes and the amount of gas in each part decreases, the gas from the flame mouth B, the flame mouth C, and the flame mouth F Since the gas is ejected, the gas amount is larger than the amount of gas ejected from only the flame port B and the flame port C, and the gas is ejected from the flame port D, the flame port E, and the flame port G. Therefore, the amount of gas in the combustible range can be ensured in the discharge space because the amount of gas is larger than the amount of gas ejected from only the flame mouth D and the flame mouth E. Therefore, since the gas stove does not ignite or goes off and the safety device does not operate, it can be used with confidence that it cannot be used.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by the form of a present Example.

Reference numeral 40 denotes a collision flame that heats the thermoelectric element 31 that detects the presence or absence of combustion in the extinguishing safety device formed by the collision flow caused by the ejection of gas from the flame outlet D34 and the flame outlet E35 formed in the burner outer peripheral wall 10.

  As a result, a cross-sectional shape in which one end 13 protrudes upward from the other end surface 14 of the convex portion 9 provided with the concave portion 8 and the convex portion 9 on the upper surface of the burner cap 4 that is detachably attached to the annular head portion of the burner body 3. The main flame mouth part 12 is formed by disposing the flame mouth A11 having the radial shape toward the center side, and the concave amount between the flame mouths A11 is larger than the center side so that the amount of the concave part is increased toward the outer peripheral wall 10 side. By mounting the gas stove burner 2 composed of the inclined burner cap 4 on the gas stove 1, when the gas stove 1 is used, the gas supplied from the burner body 3 is burned at the main flame opening 12 When a phenomenon occurs in which the broth or the like of the cooked food or the like in the heated object 17 is spilled while the heated object 17 is being heated, To the top of the burner cap 4 That. The boiled spilled juice flows over the upper surface of the burner cap 4. Since this flow flows from the convex portion 8 to the concave portion 8 which becomes the bottom as compared with the convex portion 9, the concave portion 8 serves as a flow channel, and the concave portion 8 is inclined toward the outer peripheral side 10 of the burner cap 4. Since it is configured, it flows to the outer periphery of the burner cap 4. Therefore, the flame mouth A11 does not clog unless the broth spilled from the object to be heated 17 is directly spilled into the flame mouth, so that the flame mouth load during combustion due to clogging of the flame mouth A11 increases. A stable combustion state is maintained because there is no blow-off phenomenon or blow-out phenomenon of the combustion flame at the time of combustion. Therefore, the normal phenomenon can occur without causing any abnormality in the gas supply at the time of ignition to the ignition electrode portion 23 provided outside the burner cap 4 or the combustion for heating the thermoelectric element 31 of the extinguishing safety device provided at the same position. Maintained. Furthermore, since the flared portion A11 is provided in the convex portion 9 and the concave portions 8 are provided on both sides of the flared portion A11, the concave portion 8 becomes a flow path for spillage from the heated object 17 and the like, and the spilled guide In addition to providing the above-mentioned effect, it is possible to provide a stable and safe and easy-to-use gas stove 1 because it is prevented from flowing into the gas stove 1 through the opening on the upper surface of the gas stove burner 2 by being inclined outward. It is.

  As a result, when the operation portion of the gas stove 1 is ignited, the flame outlet A11 of the burner cap 4 of the stove burner 2 is configured with the flame opening slit width 15, so that the gas ejection from the flame outlet A11 is directed obliquely upward. become. A swirling flow is generated by the gas jetted obliquely upward and flowing obliquely upward along the circumference. At the same time, since the gas from the flame outlet A11 has an obliquely upward velocity, a part of the swirling flow is caused by the centrifugal force generated by the swirling flow at the outer portion 18 of the burner cap 4 to burner cap 4. It swivels out of the outer diameter of the outside. Accordingly, a part of the swirling flow swirling outside the outer diameter of the burner cap 4 flows into the discharge space 22 constituted by the outer peripheral wall 10 and the covering body 19 of the burner cap 4 from the opening A20. It is turning. At the same time, gas is jetted counterclockwise from the flame outlet B28, and gas is jetted clockwise from the flame outlet C29 to coexist in the discharge space 22 as a collision flow. In such a state where the swirl flow and the collision flow coexist, when the electric discharge is performed from the ignition electrode 23 toward the discharge target 25, the ignition is surely ignited, and the ignition collision flame 39 formed by the flame port B28 and the flame port C29 is caused. As an ignition source, the gas emitted from the main flame 16 starts to burn in the main flame opening portion 12. Combustion is obtained by sucking and supplying secondary air from the central secondary air passage hole 5 to obtain optimum good combustion.

Further, gas is ejected from the flame outlet B28, the flame orifice C29, the flame orifice D34, and the flame orifice E35 in the direction in which both collide in the tangential direction of the outer peripheral wall 10 of the burner cap 4. Therefore, since the ignition collision flame 39 and the collision flame 40 obtained by jetting from both flame ports form a collision point in the vicinity of the outer peripheral wall 10 of the burner cap 4, a negative pressure is generated between the collision point and the outer peripheral wall of the burner cap 4. Since the region is formed, the Coanda effect is generated, and more stable ignition collision flame 39 and collision flame 40 are obtained, so that more stable ignition and combustion can be obtained.

  Further, the main flame opening portion 12 is swirled by a force that blows out in the circumferential direction when the main flame 16 is obliquely upward, and a force that exhaust heat is further discharged from the upper direction through the bottom of the object to be heated 17. As a result, more secondary air can be sucked in than the central secondary air passage hole 5, and good combustion can be obtained. Accordingly, when the object to be heated 17 is heated by swirling combustion, the combustion gas is forced to be stirred by the swirling flow, so that a turbulent flow state occurs. Since the turbulent combustion gas flows on the surface of the object to be heated 17, the temperature boundary layer generated between the surface of the object to be heated 17 and the combustion gas becomes thin, so that the heat transfer coefficient between the object to be heated 17 and the combustion gas becomes large. Become. Therefore, the amount of heat transferred from the combustion gas to the object to be heated 17 increases. The gas stove 1 equipped with the above-described stove burner 2 can provide an energy-saving gas stove 1 with high thermal efficiency. In addition, since good combustion is obtained by stirring, the distance between the bottom of the article to be heated 17 and the stove burner 2 can be reduced, and energy saving and thermal efficiency can be improved.

  In addition, since the ignition electrode 23 is covered with the covering 19 that forms the discharge space portion 22, the ignition electrode 23 may get wet even if boiled juice spills or spills from the heated object 17 or the like during cooking. Or since it does not become dirty, it discharges reliably without causing an electric leak, so that it is possible to provide a gas stove 1 that is easy to use by reliable ignition.

  Further, a part of the gas flows into the discharge space 22 until ignition, but the main flame 16 is related to the combustion speed of the combustion flame or the amount of combustion air formed in the flame outlet A11 simultaneously with the ignition. Since there is no phenomenon that protrudes to the outer side 18 of the burner cap 4, the ignition collision flame 39, the collision flame 40, and the main flame 16 formed in the flame outlet A11 do not interfere with each other, so that there is no shortage of combustion air during combustion. As a result, good combustion can be obtained, and a safe and economical gas stove 1 with little loss of combustion heat can be provided.

  Further, in the stove burner 2 that is ignited by the above-described ignition configuration and forms the swirling main flame 12 on the upper surface of the burner cap 4, one end 32 protrudes from the other end surface 33 at a suitable position on the outer peripheral wall 10 of the burner cap 4. The thermoelectric element heating section 36 is formed in such a manner that the flame mouth D34 and the flame mouth E35 having a cross section facing each other are formed, and the mixed gas supplied from the burner body 3 is ejected to form the impingement flame 40. By disposing the thermoelectric element 31 of the safety device at a substantially intermediate portion of the portion 36, gas is ejected from the flame outlet D34 in the circumferential direction of the outer periphery of the burner cap 4, and is ejected from the flame outlet E34 from the flame outlet D34. Spout in the circumferential direction opposite to the gas. Accordingly, the gas ejected from the flame port D34 and the gas ejected from the flame port E35 are in a flow state of colliding at a substantially intermediate portion between the flame port D34 and the flame port E35. Therefore, when combustion is started at the flame mouth D34 and the flame mouth E35, the heating flame 32 formed at the time of combustion forms a collision flame 40 between the flame mouth D34 and the flame mouth E35.

  At the same time, a swirl flow is exhibited at the flame outlet A11 and combustion is continued, so that a swirl flow of secondary air is generated around the stove burner 2. Therefore, the collision flame 40 is also formed in the swirl flow. The swirling flow acts as if blown away, but the gas from the flame outlet D34 is jetted in the direction opposite to the jet direction from the flame outlet E35, so that the force of the swirling flow is balanced with the flow facing the swirling flow. As a result, the collision flame 40 continues to burn stably without being blown off, so that the thermoelectric element 31 of the safety device is stably heated by the collision flame 40. Therefore, it is possible to provide a gas stove 1 that is easy to use and does not cause a problem of disappearing during use.

As described above, the gas stove in the present embodiment provides an ignition configuration that can ensure stable ignition performance in the configuration in which all the flame openings A11 are provided on the upper surface side of the burner cap 4.

The main flame mouth part 12 is formed by arranging the flame mouth A11 having a radial shape toward the center side, and the flame mouth B28 and the flame mouth are formed on the outer peripheral wall 10 of the burner cap 4 corresponding to the gap 8 between the flame mouths A11. The gas stove burner 2 constituted by the ignition flame port 30 constituted by C29 is mounted on the gas stove 1, so that when the gas stove 1 is used, the gas supplied from the burner body 3 at the main flame port 12 is The boiled simmered juice is a side surface of the heated object 17 when a phenomenon occurs in which the broth of the cooked food or the like in the heated object 17 is spilled during the heating of the heated object 17 by burning. Or directly burner cap Fall to the upper surface. The boiled spilled juice flows over the upper surface of the burner cap 4. Since this flow flows from the convex portion 8 to the concave portion 8 which becomes the bottom as compared with the convex portion 9, the concave portion 8 serves as a flow path of the flow, and the concave portion 8 is inclined to the outer peripheral side of the burner cap 4. Therefore, the ignition flame mouth portion 30 constituted by the flame mouth B28 and the flame mouth C29 provided between the recesses 8 serving as the flow passage flows in the direction of the outer peripheral wall 10 of the burner cap 4, and does not exist on the extension line of the flow passage. So it won't get clogged with boiling juice. Therefore, unless the broth spilled from the object to be heated 17 is directly spilled into the flame outlet B28 and the flame outlet C29, the flame outlet B28 and the flame outlet C29 do not clog. Due to clogging, there is no ignition failure due to the absence of gas in the discharge space 22 during ignition. Therefore, the gas stove 1 that is stable and safe and easy to use can be provided.

  In addition, since there is no phenomenon that clogs the flame opening B28 and the flame opening C29, the area of the flame mouth does not decrease. As a result, a stable combustion state is maintained. Therefore, since the normal phenomenon is maintained without causing abnormal gas supply at the time of ignition to the discharge space portion 22 provided on the outer side 18 of the burner cap 4, it is possible to provide the gas stove 1 that is stable and safe and easy to use. is there.

(Embodiment 3)
The thermoelectric element and combustion state of the extinguishing safety device according to the third embodiment of the present invention will be described with reference to the diagram shown in the first embodiment. In addition, the same number is attached | subjected to the same function and effect | action as another embodiment, and description is abbreviate | omitted.

  In the figure, the flame outlet D34 and the flame outlet E35 having a cross section in which one end 32 protrudes from the other end surface 33 between the recesses 8 of the burner cap 4 on the outer peripheral wall of the burner cap 4 facing the thermoelectric element 31 are arranged to face each other. The thermoelectric element heating part 36 is formed.

Thereby, it has a cross-sectional shape in which one end 13 protrudes upward from the other end surface 14 of the convex portion 9 provided with the concave portion 8 convex portion 9 on the upper surface of the burner cap 4 that is detachably attached to the annular head of the burner body 3. The flame mouth A11 is radially arranged toward the center to form the main flame mouth part 12, and the outer wall of the burner cap 4 corresponding to the space between the flame mouths A11 is composed of the flame mouth D34 and the flame mouth E35. Since the gas stove burner 2 configured by the thermoelectric element heating unit 36 is mounted on the gas stove 1, when the use of the gas stove 1 is started, the gas supplied from the burner body 3 is burned at the main flame opening 12. When a phenomenon occurs in which the broth or the like of the cooked food in the heated object 17 is spilled while the heated object is being heated, Upper surface of burner cap 4 Fall. The boiled spilled juice flows over the upper surface of the burner cap 4. Since this flow flows from the convex portion 9 to the concave portion 8 which becomes the bottom as compared with the convex portion 9, the concave portion 8 serves as a flow path of the flow, and the concave portion 8 is inclined to the outer peripheral side of the burner cap 4. Therefore, the ignition flame mouth portion 30 composed of the flame mouth D34 and the flame mouth E35 provided between the recesses 8 serving as the flow passage flows in the direction of the outer peripheral wall 10 of the burner cap 4 and does not exist on the extension line of the flow passage. So it won't get clogged with boiling juice. Therefore, unless the broth spilled from the object to be heated 17 is spilled directly into the flame outlet D34 and the flame outlet E35, the flame mouth D34 and the flame outlet E35 do not clog. Since the non-heating state of the thermoelectric element 31 due to the collision flame 40 extinguishing at the time of use due to clogging does not occur, there is no operation in which the safety device disappears and the gas supply is shut off. Therefore, the gas stove 1 that is stable and safe and easy to use can be provided.

  In addition, since there is no phenomenon of clogging the flame outlet D34 and flame outlet E35, the area of the flame mouth does not decrease. As a result, a stable combustion state is maintained. Therefore, the normal phenomenon is maintained without causing abnormal gas supply to the flame outlet D34 and the flame outlet E35 of the thermoelectric element provided on the outer side 18 of the burner cap 4, so that the gas stove 1 having a stable and safe user-friendliness is obtained.

In addition, the same number is attached | subjected to the same function and effect | action as another embodiment, and description is abbreviate | omitted.

  In the figure, a flame mouth B28 and a flame mouth C29 that form the ignition flame mouth portion 30 and a flame mouth D34 and a flame mouth E35 that form the thermoelectric element heating portion 36 are formed by projecting one end 13 from the other end surface 14. A flat portion 41 is provided on the A11 surface, and flames facing each other along the outer peripheral wall 10 surface of the burner cap 4 are formed.

  Thus, the ignition flame opening 30 is constituted by the flame outlet B28 and the flame opening C29 provided with the plane portion on the flame outlet A11 surface, and the thermoelectricity is provided by the flame outlet D34 and the flame outlet E35 provided with the plane portion 41 on the flame orifice A11 surface. Since the element heating unit 36 is configured, the flow direction of the gas to be ejected is restricted, so that the gas is ejected in the tangential direction of the outer periphery of the burner cap 4 along the parallel part. Accordingly, since the collision point of the ignition collision flame 39 and the collision flame 40 obtained by jetting from both flame outlets exists in the vicinity of the outer periphery of the burner cap 4, a negative pressure region is present between the collision point and the outer peripheral wall 10 of the burner cap 4. The ignition collision flame 39 and the collision flame 40 which are formed and are more stable by the Coanda effect are obtained. Therefore, since the normal phenomenon is maintained, the gas stove 1 that is stable and safe and easy to use can be provided.

(Embodiment 5)
9 and 10 show the cross-sectional shapes of the flame mouth F and the flame mouth G according to the fifth embodiment of the present invention.
In addition, the same number is attached | subjected to the same function and action as Embodiment 1, and description is abbreviate | omitted.

In the figure, a flame port F42 for ejecting a mixed gas in a direction different from the ejection direction of the flame port B28 and the flame port C29 is provided between the flame port B28 and the flame port C29 forming the ignition flame port part 30, or Between the flame mouth D34 and the flame mouth E35 forming the thermoelectric element heating unit 36, a flame mouth G43 for ejecting a mixed gas in a direction different from the ejection direction of the flame mouth D34 and the flame mouth E35 is provided. One or both of the flame outlets G43 are provided.

  Thereby, a flame is formed outwardly from the outer peripheral wall 10 of the burner cap 4 and burns at a substantially middle portion of the ignition collision flame 39 and the collision flame 40 formed along the outer peripheral wall 10 of the burner cap 4. Therefore, the total gas amount in the ignition flame port 30 and the thermoelectric element heating unit 36 increases, each flame volume becomes larger, ignition is more sure, and at the same time, heating of the thermoelectric element 31 is more reliable, Even if the position of the ignition electrode 23, the discharge target 25, the thermoelectric element 31 or the like is slightly displaced due to assembly variations, a large amount of gas is secured, so that stable performance can be obtained.

  Further, even if the gas supply pressure supplied to the burner 2 is reduced when the gas stove 1 is used, the amount of combustion changes due to a decrease in the amount of gas in each part, the flame outlet B28, the flame outlet C29, and the flame outlet F42. The gas is ejected from the nozzle B28 and the nozzle C29, so that the amount of gas is larger than that from the nozzle B28 and the nozzle C29, and the gas is ejected from the nozzle D34, the nozzle E35 and the nozzle G43. Therefore, the amount of gas in the combustible range should be ensured in the discharge space because the amount of gas is larger than the amount of gas ejected from only the flame outlet D34 and the flame outlet E35.
