Referring to fig. 1, the present application provides a method for controlling a burner, including step S100 and step S200.

Step S100: acquiring the aggregation information of the flame in the combustor during the operation of the combustor.

Specifically, the combustor includes burning main part and ignition needle, and the ignition needle connects in the burning main part, has seted up the venthole in the burning main part, and at the in-process of combustor work, the venthole blowout from burning main part is followed to the gas, and the ignition needle exports high voltage electric arc to light from the venthole blowout gas and form flame.

More specifically, the burning main part is including furnace end, branch fire dish and the outer loop fire lid that stacks gradually the setting, and the inner ring fire lid is worn to locate the middle part of outer loop fire lid and is divided the fire dish butt. The outer ring fire cover is provided with an outer ring gas outlet hole for the outer ring gas to flow out, and the inner ring fire cover is provided with an inner ring gas outlet hole for the inner ring gas to flow out. In the working process of the burner, the inner ring gas is sprayed out from the inner ring gas outlet hole in the burning main body and forms inner ring flame under the action of the ignition needle, the outer ring gas is sprayed out from the outer ring gas outlet hole in the burning main body and forms outer ring flame under the action of the ignition needle, and the outer ring flame is arranged around the circumference of the inner ring flame. The flame includes inner ring flame and outer loop flame, and the venthole includes inner ring gas venthole and outer loop gas venthole.

It should be understood that the manner of obtaining the aggregate information of the flames in the burner is not exclusive, and for example, the aggregate information may be acquired by a detection device disposed in the burner and then directly sent to the controller; or the user may obtain the measurement result from a measurement device disposed in the combustor and input the measurement result to the controller through a corresponding interaction device (e.g., a key, a touch screen, etc.).

Referring to fig. 2, specifically, the aggregate information may be any one or both of a size parameter of the flame in the radial direction of the burner and an area that can be covered by the flame in the radial direction of the burner. Step S100: acquiring the aggregated information of the flame of the burner during the operation of the burner may include the step S110: acquiring a size parameter of the flame in a radial direction of the combustor during the operation of the combustor; alternatively, the method may further include step S120: in the working process of the burner, the area which can be covered by the flame of the burner in the radial direction of the burner is obtained.

Specifically, a plurality of reference planes which are sequentially stacked are defined in the axial direction of the combustor, a plurality of radial lines of the combustor are arranged in each reference plane, each radial line in each reference plane simultaneously penetrates through the flame and sequentially intersects with the flame at four different intersection points, and the four intersection points are respectively named as a first intersection point, a second intersection point, a third intersection point and a fourth intersection point in sequence. The first and fourth intersection points are the intersection points of the radial line and the outer flame of the flame, and the second and third intersection points are the intersection points of the inner flame of the radial line. And the distance between the first intersection point and the fourth intersection point of the same radial line and the flame is the radial distance of the flame. In each reference plane, a plurality of radial lines intersect with the flame to form a plurality of radial intervals, wherein the radial interval with the largest interval value is the largest radial distance of the flame in the reference plane, and each reference plane has one radial line intersecting with the flame to form the largest radial interval. The dimensional parameter of the flame in the radial direction of the burner refers to the maximum radial spacing of any one reference plane. If the aggregated information is a dimension parameter of the flame in the radial direction of the combustor, the dimension parameter of the flame in the radial direction of the combustor is taken as a maximum value among a plurality of maximum radial intervals sequentially arranged along the axial direction of the combustor.

When each reference plane penetrates through the flame, the area overlapped with the flame is a radial area, and the area which can be covered by the flame in the radial direction of the burner refers to the area overlapped with the flame when any reference plane penetrates through the flame. If the aggregate information is the area that can be covered by the flame in the radial direction of the burner, the description will be given by taking as an example that the area that can be covered by the flame in the radial direction of the burner is the maximum value among the areas that overlap with the flame in a plurality of reference planes sequentially arranged in the axial direction of the burner when the burner is in the off-pot state.

The size parameter of the flame in the radial direction of the combustor may include at least one of a size parameter of the inner ring flame in the radial direction of the combustor and a size parameter of the outer ring flame in the radial direction of the combustor. The area that the flame can cover in the radial direction of the combustor may include at least one of an area that the inner ring flame can cover in the radial direction of the combustor and an area that the outer ring flame can cover in the radial direction of the combustor.

Step S200: and when the pot-leaving condition is met based on the aggregated information, controlling a pot-leaving adjusting device corresponding to the pot-leaving condition to execute a first action so as to reduce the firepower output by the burner. Specifically, the pan-out condition corresponds to the pan-out adjustment device, and the firepower output by the burner can be adjusted when the pan-out adjustment device executes the first action, so that the firepower output by the burner matches the aggregated information.

Specifically, the off-pot condition may be a judgment condition set according to the needs of a general user group, or may also be a judgment condition set according to the needs of a special user group. The condition of leaving the pot is not unique, and can be adjusted according to the requirement of a user in actual operation.

For example, taking the aggregated information as the size parameter of the flame in the radial direction of the burner and the off-pot condition as the size parameter of the flame in the radial direction of the burner is less than or equal to the first preset value as an example, step S200: when the out-of-pot condition is satisfied based on the aggregated information, controlling an out-of-pot adjustment device corresponding to the out-of-pot condition to perform a first action to reduce the firepower output by the burner, including step S210: when the size parameter of the flame in the radial direction of the burner is smaller than or equal to a first preset value, the size parameter of the flame in the radial direction of the burner is judged to meet a pan-leaving condition, and the pan-leaving adjusting device corresponding to the pan-leaving condition is controlled to execute a first action so as to reduce the firepower output by the burner.

For another example, taking the aggregation information as the area that the flame can cover in the radial direction of the burner and the off-pot condition as the area that the flame can cover in the radial direction of the burner is less than or equal to the second preset value as an example, step S200: when the out-of-pot condition is satisfied based on the aggregated information, controlling an out-of-pot adjustment device corresponding to the out-of-pot condition to perform a first action to reduce the firepower output by the burner, including step S220: when the area which can be covered by the flame in the radial direction of the burner is smaller than or equal to a second preset value, the area which can be covered by the flame in the radial direction of the burner is judged to meet the pot leaving condition, and the controller controls the pot leaving adjusting device corresponding to the pot leaving condition to execute a first action so as to reduce the firepower output by the burner.

The method for controlling the burner includes the steps of S100: acquiring the aggregation information of the flame in the burner in the working process of the burner, and step S200: when the pot leaving condition is met based on the aggregated information, the pot leaving adjusting device corresponding to the pot leaving condition is controlled to execute a first action so as to reduce the firepower output by the burner, so that the burner can automatically reduce the output firepower when the aggregated information meets the pot leaving condition, energy conservation and emission reduction are facilitated, and the operating efficiency of the burner can be effectively improved.

Preferably, step S100: acquiring the aggregation information of the flame in the combustor in the working process of the combustor, wherein the aggregation information comprises;

step S110: acquiring a size parameter of the flame in a radial direction of the combustor during the operation of the combustor;

step S200: when a pot-leaving condition is satisfied based on the aggregated information, controlling a pot-leaving adjusting device corresponding to the pot-leaving condition to perform a first action to reduce the firepower output by the burner, including:

step S210: when the pot-leaving condition is satisfied based on a size parameter of the burner in the radial direction, controlling the pot-leaving adjusting device corresponding to the pot-leaving condition to execute a first action so as to reduce the firepower output by the burner.

Specifically, the burner has a pot-sitting state and a pot-leaving state, when the burner is in the pot-sitting state, the pot is located above the burner and heated under the action of inner ring flame and outer ring flame of the burner, the pot is not guaranteed to have higher heating efficiency, and at the moment, the burner is required to output larger firepower; when the burner is in a state of being away from the pot, the pot is separated from the burner, and a user can clean the pot.

When the burner is in a pot-sitting state, under the action of a pot, the inner ring flame and the outer ring flame are both expanded along the radial direction of the burner, and the size parameters of the inner ring flame and the outer ring flame in the radial direction of the burner are also increased; when the burner is in a state of being away from the pot, the inner ring flame and the outer ring flame are both automatically furled along the radial direction of the burner, and the size parameters of the inner ring flame and the outer ring flame in the radial direction of the burner are also reduced. Therefore, during the state switching process of the burner between the pot-sitting state and the pot-leaving state, the dimension parameters of the inner ring flame and the outer ring flame in the radial direction of the burner can be sensitively changed along with the state change of the burner. Thus, by step S110: acquiring a dimension parameter of the flame in a radial direction of the burner during operation of the burner, and step S210: when the radial dimension parameter based on the burner meets the pan-leaving condition, the pan-leaving adjusting device corresponding to the pan-leaving condition is controlled to execute a first action so as to reduce the firepower output by the burner, so that the controller can acquire the state change of the burner in time, and further the controller can control the firepower output by the burner according to the state change of the burner, so that the burner has higher operation efficiency.

Referring to fig. 3, further, step S100: acquiring the aggregation information of the flame in the combustor in the working process of the combustor, wherein the aggregation information comprises;

step S130: and acquiring the aggregated information of the inner ring flame in the combustor in the working process of the combustor.

In the working process of the burner, the inner ring flame is positioned at the inner side of the outer ring flame, so that the inner ring flame is less influenced by external environmental factors (such as wind), and the inner ring flame is not easy to swing, so that the burner has better combustion stability. Therefore, the acquired aggregation information is more accurate. Then in the process of combustor work, the controller can accurate the gathering information that obtains inner ring flame, for example the radial ascending size parameter of inner ring flame at the combustor to whether the judgement that can be accurate according to the gathering information gathers information and satisfies from the pot condition, so that the controller can be accurate and timely control combustor with suitable firepower output.

Referring to fig. 4, specifically, step S100: acquiring aggregated information of a flame in a burner during operation of the burner, including:

step S140: in the working process of the burner, acquiring parameter information of a pot-sitting combustion area of flame in the burner;

step S150: acquiring the aggregation information of the flame in the combustor according to the parameter information;

When the combustor is in the state of sitting on the pot, the pan is located in the top of combustor to heat under the effect of the inner ring flame of combustor and outer loop flame, when the combustor is in the state of leaving the pot, pan and combustor separation, the user can wash the pan. In particular, the pot-sitting combustion region of flames may comprise at least one of a pot-sitting combustion region of inner ring flames and a pot-sitting combustion region of outer ring flames. The pot-sitting combustion area of the inner ring flame refers to the area where the inner ring flame in the burner can reach when the burner is in a pot-sitting state, and the inner ring flame in the burner cannot reach when the burner is in a pot-leaving state. That is, the seated combustion region of the inner ring flame refers to a region where the inner ring flame in the burner can burn when the burner is in the seated state, and the inner ring flame in the burner cannot burn when the burner is in the away state. Similarly, the sitting-pot combustion area of the outer ring flame refers to an area where the outer ring flame in the burner can reach when the burner is in the sitting-pot state, and the outer ring flame in the burner cannot reach when the burner is in the off-pot state.

Specifically, the parameter information includes at least one of temperature, thermoelectric potential, and thermal energy radiation intensity. When the burner is in a pot-sitting state, under the action of the pot, the inner ring flame and the outer ring flame are both expanded to respective pot-sitting combustion areas along the radial direction of the burner, so correspondingly, the temperature, the thermoelectric potential and the heat energy radiation intensity in the pot-sitting combustion areas of the inner ring flame are all increased, and the temperature, the thermoelectric potential and the heat energy radiation intensity in the pot-sitting combustion areas of the outer ring flame are also increased. When the burner is in a state of being away from the boiler, the inner ring flame and the outer ring flame are automatically furled along the radial direction of the burner, and flames do not exist in the boiler sitting combustion area of the inner ring flame and the boiler sitting combustion area of the outer ring flame, so that the temperature, the thermoelectric potential and the heat energy radiation intensity in the boiler sitting combustion area of the inner ring flame are all reduced, and the temperature, the thermoelectric potential and the heat energy radiation intensity in the boiler sitting combustion area of the outer ring flame are also all reduced. Therefore, the temperature, the thermoelectric potential and the heat energy radiation intensity in the sitting boiler combustion area of the inner ring flame and the temperature, the thermoelectric potential and the heat energy radiation intensity in the sitting boiler combustion area of the outer ring flame can be changed along with the state change of the burner. Therefore, the controller can timely and sensitively acquire the state change of the burner by setting the parameter information of the controller according to the sitting boiler combustion area of the flame in the burner and acquiring the aggregation information of the flame of the burner according to the parameter information, so that the firepower output by the burner is conveniently controlled according to the state change of the burner, and the burner has higher operation efficiency.

Specifically, the combustor further comprises a first detection piece, wherein the first detection piece is connected to the combustion main body in a coupling mode and used for detecting parameter information of a pot setting combustion area of flame in the combustor and sending the parameter information to the controller, so that the controller can obtain aggregation information of the flame of the combustor according to the parameter information.

Alternatively, the first detection member may be a thermocouple for detecting a thermoelectric potential of the pot burning region of the flame; alternatively, the first detecting member may be a thermistor, and the thermistor is used for detecting the temperature of the pot burning area of the flame.

For example, the first detection element detects that the temperature of a pot-sitting combustion area of the inner ring flame is a first temperature, the first temperature is sent to the controller, the controller obtains the size parameter of the inner ring flame in the burner in the radial direction according to the first temperature, and judges whether the size parameter of the inner ring flame in the radial direction of the burner is smaller than or equal to a first preset value, if yes, the controller controls the pot-leaving adjustment element corresponding to the pot-leaving condition to execute a first action, so that the firepower output by the burner is reduced.

For another example, the first detection element detects that the thermoelectric force of the pot-sitting combustion area of the inner ring flame is the first thermoelectric force, and sends the first thermoelectric force to the controller, the controller obtains the area which can be covered by the inner ring flame in the burner in the radial direction of the burner according to the first thermoelectric force, and judges whether the area which can be covered by the inner ring flame in the radial direction of the burner is smaller than or equal to the second preset value, if so, the controller controls the pot-leaving adjustment element corresponding to the pot-leaving condition to execute the first action, so as to reduce the firepower output by the burner.

Referring to fig. 5, the burner further includes an injection pipe and a gas valve, the gas valve is coupled to the injection pipe, and the pot-leaving adjusting device includes a gas valve;

step S230: and when the out-of-boiler condition is satisfied based on the aggregated information, controlling the gas valve corresponding to the out-of-boiler condition to reduce the opening degree so as to reduce the firepower output by the burner.

Specifically, draw and penetrate the pipe and connect in the burning main part, draw and penetrate the pipe and be used for to the burning main part internal injection gas to make the gas can spout and burn through the gas outlet. When the opening degree of the gas valve is reduced, the gas injected into the combustion main body is reduced, and the gas sprayed out of the gas outlet is reduced, so that the output firepower is reduced. When the opening degree of the gas valve is increased, the amount of gas injected into the combustion main body is increased, and the amount of gas ejected from the gas outlet is increased, so that the output heat is increased. By setting step S230: and when the boiler leaving condition is met based on the aggregated information, controlling the gas valve corresponding to the boiler leaving condition to reduce the opening degree so as to reduce the firepower output by the burner, so that the controller can directly and effectively control the firepower output by the burner.

More specifically, draw and penetrate the pipe and draw and penetrate pipe and gas distribution pipe including inner ring, outer loop, the gas valve joins in marriage and connects on the gas distribution pipe, and the gas is shunted and is formed inner ring gas and outer loop gas in gas distribution pipe department, and the inner ring gas flows to the inner ring and draws and penetrate the pipe, and outer loop gas flows to the outer loop and draws and penetrate the pipe.

The inner ring injection pipe is used for injecting inner ring fuel gas into the combustion main body, and the outer ring injection pipe is used for injecting outer ring fuel gas into the combustion main body. The aperture of gas valve reduces, but the inner ring gas and the outer loop gas flow that the simultaneous control inner ring penetrated pipe and the outer loop and penetrated the pipe and input respectively reduce, and the aperture increase of gas valve can the simultaneous control inner ring penetrated pipe and the outer loop and penetrated the pipe and inject inner ring gas and the outer loop gas flow that the pipe was input respectively and increase.

Referring to fig. 6, in addition, the method for controlling the burner further includes step S300: when the off-pot condition is not satisfied based on the aggregated information, the burner is controlled to maintain the output power unchanged, and therefore, the burner has high thermal efficiency, thereby enabling rapid heating of the pot.

Referring to fig. 7, further, in step S200: after the controlling, when a pot exit condition is satisfied based on the aggregated information, a pot exit adjusting device corresponding to the pot exit condition to perform a first action to reduce the firepower output by the burner, the method further includes:

step S400: when the off-pot condition is not satisfied based on the aggregated information, controlling the burner to output greater than the fire power when the off-pot adjustment means performs the first action.

That is to say, when the user puts the pan back on the combustor again, the flame of combustor will expand automatically owing to contact with the pan, and at this moment, first detection piece detects that the parameter information of the seat pot burning zone of flame in the combustor changes and feeds back to the controller, and when not satisfying based on aggregated information from the pot condition, the controller control with from pot adjusting device that from pot condition corresponds carries out the second action (for example, inner ring gas valve and outer loop gas valve increase aperture), thereby make the combustor can be greater than from the firepower output when pot adjusting device carries out first action, so that rapid heating pan. Therefore, when the burner is in a state of being away from the pot, the controller can automatically control the burner to output smaller firepower, and when the burner is in a state of being seated, the controller can automatically control the burner to output larger firepower, so that the burner can automatically adjust the firepower according to different states, and the burner has higher operation efficiency.

Referring to fig. 9, 10 and 13, the present application further provides a gas cooker, where the gas cooker includes a burner 100, the burner 100 includes a burning main body 10, a pan-off adjustment device (not shown) and a controller (not shown), the pan-off adjustment device is coupled to the burning main body 10, the controller is electrically connected to the pan-off adjustment device, and the controller is configured to obtain aggregation information of flames in the burner 100 during operation of the burner 100, and control the pan-off adjustment device corresponding to the pan-off condition to perform a first action when the pan-off condition is satisfied based on the aggregation information, so as to reduce firepower output by the burner 100.

The aggregated information of the flame in the burner 100 is acquired by adopting the controller in the working process of the burner 100, and when the pan-leaving condition is met based on the aggregated information, the pan-leaving adjusting device corresponding to the pan-leaving condition is controlled to execute the first action so as to reduce the firepower output by the burner 100, so that the burner 100 can automatically reduce the output firepower when the aggregated information meets the pan-leaving condition, thereby being convenient for energy conservation and emission reduction, and effectively improving the operating efficiency of the burner 100.

Specifically, the burner 100 further includes an ignition needle 40, the ignition needle 40 is coupled to the combustion main body 10, an air outlet is formed in the combustion main body 10, and in the working process of the burner 100, the gas is ejected from the air outlet of the combustion main body 10, and the ignition needle 40 outputs a high-voltage arc to ignite the gas ejected from the air outlet and form a flame.

More specifically, the combustion body 10 includes a burner 11, a distributor 12 and an outer ring fire cover 13, which are stacked in sequence, and the inner ring fire cover 14 is inserted into the middle of the outer ring fire cover 13 and abuts against the distributor 12. The outer ring fire cover 13 is provided with an outer ring gas outlet hole 132 for the outer ring gas to flow out, and the inner ring fire cover 14 is provided with an inner ring gas outlet hole 142 for the inner ring gas to flow out. During the operation of the burner 100, the inner ring gas is ejected from the inner ring gas outlet 142 of the combustion body 10 and acted by the ignition needle 40 to form the inner ring flame 500, and the outer ring gas is ejected from the outer ring gas outlet 132 of the combustion body 10 and acted by the ignition needle 40 to form the outer ring flame, which is arranged around the circumference of the inner ring flame 500. The flames include an inner ring flame 500 and an outer ring flame, and the gas outlets include an inner ring gas outlet 142 and an outer ring gas outlet 132.

It should be understood that the manner of obtaining the aggregate information of the flame in the combustor 100 is not exclusive, and for example, the aggregate information may be collected by a detection device disposed in the combustor 100 and then directly sent to the controller; the user may also obtain the measurement result from a measurement device disposed in the burner 100 and input the measurement result to the controller through a corresponding interaction device (e.g., a button, a touch screen, etc.).

Specifically, the aggregate information may be any one of or both of a size parameter of the flame in the radial direction of the combustor 100 and an area that can be covered by the flame in the radial direction of the combustor 100. The controller obtains the aggregation information of the flame of the combustor 100 during the operation of the combustor 100, which may be a size parameter of the flame in a radial direction of the combustor 100 obtained during the operation of the combustor 100 by the controller; alternatively, the controller may obtain the area covered by the flame of the combustor 100 in the radial direction of the combustor 100 during the operation of the combustor 100.

Specifically, a plurality of reference planes which are sequentially stacked in the axial direction of the combustor 100 are defined, a plurality of radial lines of the combustor 100 are arranged in each reference plane, each radial line in each reference plane simultaneously penetrates through the flame and sequentially intersects with the flame at four different intersection points, and the four intersection points are respectively named as a first intersection point, a second intersection point, a third intersection point and a fourth intersection point in sequence. The first and fourth intersection points are the intersection points of the radial line and the outer flame of the flame, and the second and third intersection points are the intersection points of the inner flame of the radial line. And the distance between the first intersection point and the fourth intersection point of the same radial line and the flame is the radial distance of the flame. In each reference plane, a plurality of radial lines intersect with the flame to form a plurality of radial intervals, wherein the radial interval with the largest interval value is the largest radial distance of the flame in the reference plane, and each reference plane has one radial line intersecting with the flame to form the largest radial interval. The dimensional parameter of the flame in the radial direction of the burner 100 refers to the maximum radial spacing of any one reference plane. If the aggregate information is a dimension parameter of the flame in the radial direction of the combustor 100, the dimension parameter of the flame in the radial direction of the combustor 100 is a maximum value among a plurality of maximum radial pitches sequentially arranged in the axial direction of the combustor 100.

When each reference plane passes through the flame, the area coinciding with the flame is a radial area, and the area that the flame can cover in the radial direction of the burner 100 refers to the area coinciding with the flame when any one reference plane passes through the flame. If the aggregate information is the area that can be covered by the flame in the radial direction of the burner 100, the description will be given taking as an example the case where the area that can be covered by the flame in the radial direction of the burner 100 is the maximum value among the areas where the flame overlaps with a plurality of reference planes sequentially arranged in the axial direction of the burner 100 when the burner 100 is in the off-pot state.

The size parameter of the flame in the radial direction of the combustor 100 may include at least one of the size parameter of the inner ring flame 500 in the radial direction of the combustor 100 and the size parameter of the outer ring flame in the radial direction of the combustor 100. The area that the flame can cover in the radial direction of the combustor 100 may include at least one of an area that the inner ring flame 500 can cover in the radial direction of the combustor 100 and an area that the outer ring flame can cover in the radial direction of the combustor 100.

When the out-of-pot condition is satisfied based on the aggregated information, the controller controls the out-of-pot adjustment device corresponding to the out-of-pot condition to perform a first action to reduce the firepower output by the burner 100. Specifically, the out-of-pot condition corresponds to the out-of-pot adjustment device, and the firepower output from the burner 100 can be adjusted so that the firepower output from the burner 100 matches the aggregated information when the out-of-pot adjustment device performs the first action.

For example, taking the aggregated information as the size parameter of the flame in the radial direction of the burner 100 and the off-pot condition as the size parameter of the flame in the radial direction of the burner 100 being less than or equal to the first preset value as an example, when the off-pot condition is satisfied based on the aggregated information, the controller controls the off-pot adjusting device corresponding to the off-pot condition to perform the first action to reduce the firepower output by the burner 100, including when the size parameter in the radial direction of the burner 100 based on the flame is less than or equal to the first preset value, the controller judges that the size parameter of the flame in the radial direction of the burner 100 satisfies the off-pot condition, and the controller controls the off-pot adjusting device corresponding to the off-pot condition to perform the first action to reduce the firepower output by the burner 100.

For another example, taking the aggregate information as the area that the flame can cover in the radial direction of the burner 100, and the pan-out condition as the area that the flame can cover in the radial direction of the burner 100 is less than or equal to the second preset value as an example, when the pan-out condition is satisfied based on the aggregate information, the controller controls the pan-out adjusting device corresponding to the pan-out condition to perform the first action to reduce the firepower output by the burner 100, including when the area that the flame can cover in the radial direction of the burner 100 satisfies the second preset value, the controller determines that the area that the flame can cover in the radial direction of the burner 100 satisfies the pan-out condition, and the controller controls the pan-out adjusting device corresponding to the pan-out condition to perform the first action to reduce the firepower output by the burner 100.

Specifically, after the controller controls the pot exit adjusting device corresponding to the pot exit condition to perform the first action to reduce the fire power output from the burner 100 when the pot exit condition is satisfied based on the aggregated information, the controller also controls the burner 100 to output the fire power larger than when the pot exit adjusting device performs the first action when the pot exit condition is not satisfied based on the aggregated information. The specific operation is similar to the above method, and is not described herein again.

Specifically, the controller also controls the burner 100 to maintain the output fire constant when the off-pot condition is not satisfied based on the aggregated information. The specific operation is similar to the above method, and is not described herein again.

Preferably, in the operation process of the burner 100, the controller obtains the aggregate information of the flame in the burner 100, and when the pan-out condition is satisfied based on the aggregate information, the controller controls the pan-out adjustment device corresponding to the pan-out condition to execute a first action to reduce the firepower output by the burner 100, specifically: during the operation of the burner 100, a dimension parameter of the flame in the radial direction of the burner 100 is acquired, and when the out-of-pot condition is satisfied based on the dimension parameter in the radial direction of the burner 100, the controller controls the out-of-pot adjusting device corresponding to the out-of-pot condition to execute a first action so as to reduce the firepower output by the burner 100.

Referring to fig. 9 and 10 again, specifically, the burner 100 has a pot-sitting state and a pot-leaving state, when the burner 100 is in the pot-sitting state, the pot 600 is located above the burner 100 and heated under the action of the inner ring flame 500 and the outer ring flame of the burner 100, in order to ensure that the pot 600 has higher heating efficiency, at this time, the burner 100 should output larger fire power; when the burner 100 is in the state of being separated from the pot, the pot 600 is separated from the burner 100, and the user can clean the pot 600, at this time, the burner 100 should output less fire power for saving energy.

When the burner 100 is in a seated state, under the action of the pot 600, the inner ring flame 500 and the outer ring flame both expand along the radial direction of the burner 100, and the size parameters of the inner ring flame 500 and the outer ring flame in the radial direction of the burner 100 are also increased; when the burner 100 is in the off-pot state, the inner ring flame 500 and the outer ring flame are both automatically folded along the radial direction of the burner 100, and the size parameters of the inner ring flame 500 and the outer ring flame in the radial direction of the burner 100 are also reduced. It can be seen that during the state switching of the burner 100 between the pot-on state and the pot-off state, the dimension parameters of the inner ring flame 500 and the outer ring flame in the radial direction of the burner 100 will change sensitively following the state change of the burner 100. Therefore, by setting that the controller acquires the size parameter of the flame in the radial direction of the burner 100 during the operation of the burner 100, when the size parameter in the radial direction of the burner 100 satisfies the pan leaving condition, the controller controls the pan leaving adjusting device corresponding to the pan leaving condition to perform the first action to reduce the firepower output by the burner 100, so that the controller can acquire the state change of the burner 100 in time, and further, the controller can control the firepower output by the burner 100 according to the state change of the burner 100, so that the burner 100 has higher operating efficiency.

Further, in the working process of the burner 100, the controller obtains the aggregation information of the flame in the burner 100, specifically: during operation of the combustor 100, the controller obtains aggregate information of the inner ring flames 500 in the combustor 100.

Since the inner ring flame 500 is positioned inside the outer ring flame during the operation of the burner 100, the inner ring flame 500 is less affected by external environmental factors (e.g., wind), and the inner ring flame 500 is less prone to swing, thereby having better combustion stability. Therefore, in the operation process of the burner 100, the controller can accurately acquire the aggregate information of the inner ring flame 500, for example, the size parameter of the inner ring flame 500 in the radial direction of the burner 100, and can accurately determine whether the aggregate information meets the pan leaving condition according to the aggregate information, so that the controller can accurately and timely control the burner 100 to output appropriate fire power.

Referring to fig. 11 and 12, the burner 100 further includes a first detecting member 20, wherein the first detecting member 20 is coupled to the burning body 10 and electrically connected to the controller; the first detecting part 20 is configured to detect parameter information of a pot burning area of flame in the burner 100 and send the parameter information to a controller during operation of the burner 100, the controller is configured to obtain the parameter information of the pot burning area of flame in the burner 100 and obtain aggregation information of flame in the burner 100 according to the parameter information of the pot burning area of flame; the sitting-pan combustion area of the flame is an area where the flame in the burner 100 can reach when the burner 100 is in the sitting-pan state, and the flame in the burner 100 cannot reach when the burner 100 is in the leaving-pan state.

When the burner 100 is in the state of being seated on a pot, the pot 600 is seated on the burner 100 and heated under the action of the inner ring flame 500 and the outer ring flame of the burner 100, and when the burner 100 is in the state of being separated from the pot, the pot 600 is separated from the burner 100, so that a user can clean the pot 600. Specifically, the pot burning zone of the flame may include at least one of the pot burning zone of the inner ring flame 500 and the pot burning zone of the outer ring flame. The seated combustion area of the inner ring flame 500 refers to an area where the inner ring flame 500 in the burner 100 can reach when the burner 100 is in a seated state, and the inner ring flame 500 in the burner 100 cannot reach when the burner 100 is in an off-pot state. That is, the seated combustion region of the inner ring flame 500 refers to a region in which the inner ring flame 500 can be burned in the burner 100 when the burner 100 is in the seated state, and the inner ring flame 500 cannot be burned in the burner 100 when the burner 100 is in the away state. Similarly, the sitting-pan combustion area of the outer ring flame refers to an area where the outer ring flame in the burner 100 can extend when the burner 100 is in the sitting-pan state, and the outer ring flame in the burner 100 cannot extend when the burner 100 is in the off-pan state.

Specifically, the parameter information includes at least one of temperature, thermoelectric potential, and thermal energy radiation intensity. When the burner 100 is in the seated state, under the action of the pot 600, the inner ring flame 500 and the outer ring flame both expand to respective seated combustion areas along the radial direction of the burner 100, and accordingly, the temperature, the thermoelectric potential and the heat energy radiation intensity in the seated combustion areas of the inner ring flame 500 will all increase, and the temperature, the thermoelectric potential and the heat energy radiation intensity in the seated combustion areas of the outer ring flame will also increase. When the burner 100 is in the off-pot state, the inner ring flame 500 and the outer ring flame are both automatically furled along the radial direction of the burner 100, and no flame exists in the sitting pot combustion area of the inner ring flame 500 and the sitting pot combustion area of the outer ring flame, so that the temperature, the thermoelectric potential and the heat energy radiation intensity in the sitting pot combustion area of the inner ring flame 500 are all reduced, and the temperature, the thermoelectric potential and the heat energy radiation intensity in the sitting pot combustion area of the outer ring flame are also reduced. It can be seen that the temperature, thermoelectric potential and thermal energy radiation intensity in the sitting boiler combustion area of the inner ring flame 500 and the temperature, thermoelectric potential and thermal energy radiation intensity in the sitting boiler combustion area of the outer ring flame are changed according to the state change of the burner 100. Therefore, by setting the parameter information of the controller according to the sitting boiler combustion area of the flame in the burner 100 and obtaining the aggregated information of the flame of the burner 100 according to the parameter information, the controller can timely and sharply acquire the state change of the burner 100, so as to control the firepower output by the burner 100 according to the state change of the burner 100, thereby enabling the burner 100 to have high operation efficiency.

Specifically, the first sensing member 20 may be a thermocouple for sensing a thermoelectric force of a pot burning region of the flame; alternatively, the first detecting member 20 may be a thermistor for detecting the temperature of the pot burning area of the flame.

For example, the first detecting element 20 detects that the temperature of the pan burning area of the inner ring flame 500 is the first temperature, and sends the first temperature to the controller, the controller obtains the size parameter of the inner ring flame 500 in the burner 100 in the radial direction of the burner 100 according to the first temperature, and determines whether the size parameter of the inner ring flame 500 in the radial direction of the burner 100 is smaller than or equal to the first preset value, if so, the controller controls the pan leaving adjusting element corresponding to the pan leaving condition to execute the first action so as to reduce the firepower output by the burner 100, and if not, the controller controls the pan leaving adjusting element corresponding to the pan leaving condition to not act.

For another example, the first detecting element 20 detects that the thermoelectric force of the pan burning region of the inner ring flame 500 is a first thermoelectric force, and sends the first thermoelectric force to the controller, and the controller obtains the area that the inner ring flame 500 can cover in the radial direction of the burner 100 in the burner 100 according to the first thermoelectric force, and determines whether the area that the inner ring flame 500 can cover in the radial direction of the burner 100 is smaller than or equal to a second preset value, if so, the controller controls the pan leaving adjusting element corresponding to the pan leaving condition to execute a first action to reduce the firepower output by the burner 100, and if not, the controller controls the pan leaving adjusting element corresponding to the pan leaving condition to be inactive.

Referring to fig. 11 and 12 again, specifically, the outer ring fire cover 13 surrounds the circumference of the inner ring fire cover 14 and is spaced from the inner ring fire cover 14 to form a limiting space 15 with the inner and outer fire covers, and the first detecting element 20 penetrates through the limiting space 15 along the axial direction of the outer ring fire cover 13 and is used for detecting the parameter information of the pot combustion area located in the limiting space 15. Specifically, the axial direction of the outer ring flame cover 13 coincides with the axial direction of the combustor 100. The detection area of the first detection part 20 is located in the limit space 15, due to the blocking of the outer ring fire cover 13, the influence of external environmental factors (such as wind) on the parameter information of the pot combustion area of the flame located in the limit space 15 is small, and when the first detection part 20 detects the parameter information of the pot combustion area of the flame located in the limit space 15, the stability and accuracy of the detection of the first detection part 20 are high, so that the controller can accurately and timely control the combustor 100 to output appropriate firepower.

Further, the first detecting member 20 is disposed in the pot combustion area of the inner ring flame 500, the first detecting member 20 is configured to detect parameter information of the pot combustion area of the inner ring flame 500 in the burner 100 and send the parameter information to the controller during the operation of the burner 100, and the controller is configured to obtain the aggregate information of the inner ring flame 500 in the burner 100 according to the parameter information of the pot combustion area of the inner ring flame 500.

Since the inner ring flame 500 is positioned inside the outer ring flame during the operation of the burner 100, the inner ring flame 500 is less affected by external environmental factors (e.g., wind), and the inner ring flame 500 is less prone to swing, thereby having better combustion stability. Therefore, the acquired aggregation information is more accurate. The first detecting member 20 can accurately obtain the parameter information of the sitting-boiler combustion area of the inner ring flame 500 and send the parameter information to the controller during the operation of the burner 100, and the controller can accurately obtain the aggregate information of the inner ring flame 500 in the burner 100 according to the parameter information of the sitting-boiler combustion area of the inner ring flame 500, so that the controller can accurately and timely control the burner 100 to output the appropriate fire power.

In addition, the burner 100 further comprises an ignition needle 40, and the ignition needle 40 penetrates through the limit space 15 along the axial direction of the outer ring fire cover 13. Due to the blocking of the outer ring ignition cover 13, the region in the limit space 15 is less affected by external environmental factors (such as wind), so that in the process that the ignition needle 40 outputs high-voltage electric arc to ignite the gas sprayed from the gas outlet and form flame, the wind in the external environment can be prevented from interfering the ignition needle 40 to ignite, and the inner ring gas and the outer ring gas can be ignited conveniently.

The burner 100 further comprises an injection pipe 50 and a gas valve (not shown), wherein the injection pipe 50 is connected to the combustion main body 10, the gas valve is connected to the injection pipe 50 and electrically connected with the controller, and the pot separation adjusting device comprises a gas valve; the controller is configured to control the gas valve corresponding to the leaving-pot condition to decrease the opening degree to decrease the thermal power output by the burner 100 when the leaving-pot condition is satisfied based on the aggregated information.

Specifically, the injection pipe 50 is coupled to the combustion body 10, and the injection pipe 50 is used for injecting the gas into the combustion body 10, so that the gas can be injected and combusted through the gas outlet. When the opening degree of the gas valve is reduced, the gas injected into the combustion body 10 is also reduced, and the gas injected from the gas outlet is also reduced, so that the output fire is also reduced. When the opening degree of the gas valve is increased, the amount of gas injected into the combustion body 10 is increased, and the amount of gas discharged from the gas outlet is increased, so that the output heat is increased. By controlling the gas valve corresponding to the off-pot condition to decrease the opening when the off-pot condition is satisfied based on the aggregated information to decrease the firepower output from the burner 100, the controller can directly and effectively control the firepower output from the burner 100.

More specifically, the injection pipe 50 includes an inner ring injection pipe 51, an outer ring injection pipe 52 and a gas distribution pipe (not shown), the gas valve is coupled to the gas distribution pipe, the gas is distributed at the gas distribution pipe to form inner ring gas and outer ring gas, the inner ring gas flows to the inner ring injection pipe 51, and the outer ring gas flows to the outer ring injection pipe 52.

The inner ring injection pipe 51 is used for injecting inner ring gas into the combustion main body 10, and the outer ring injection pipe 52 is used for injecting outer ring gas into the combustion main body 10. The opening degree of the gas valve is reduced, the inner ring gas and the outer ring gas flow which are respectively input by the inner ring injection pipe 51 and the outer ring injection pipe 52 can be simultaneously controlled to be reduced, the opening degree of the gas valve is increased, and the inner ring gas and the outer ring gas flow which are respectively input by the inner ring injection pipe 51 and the outer ring injection pipe 52 can be simultaneously controlled to be increased.

The burner 100 further comprises a second detecting member 30, the second detecting member 30 is coupled to the burning body 10 and electrically connected to the controller; the second sensing member 30 is configured to sense operation information of the burner 100 and transmit it to the controller during operation of the burner 100, and the controller controls the gas valve to be closed when a fault condition is satisfied based on the operation information. When the fault condition is not satisfied based on the operation information, the controller controls the gas valves to maintain the opening degrees constant, and the burner 100 outputs the current fire.

Specifically, the operating information may include at least one of a thermoelectric potential of an operating combustion zone of the flame, a temperature of the operating combustion zone of the flame, and a thermal energy radiation intensity of the operating combustion zone of the flame, the operating combustion zone of the flame including an operating combustion zone of the inner ring flame 500 and an operating combustion zone of the outer ring flame. The operating combustion zone of the inner ring flame 500 refers to the zone that the inner ring flame 500 can reach regardless of whether the burner 100 is in a seated or out-of-pot condition. That is, the operating combustion region of the inner ring flame 500 refers to a region where the inner ring flame 500 can be burned regardless of whether the burner 100 is in a pot-on state or a pot-off state. The working combustion region of the outer ring flame refers to a region that the outer ring flame can reach no matter the burner 100 is in a pot-sitting state or in a pot-leaving state. That is, the operating combustion region of the outer ring flame refers to a region that the outer ring flame can burn regardless of whether the burner 100 is in a pot-on state or a pot-off state. Specifically, the fault condition may be a judgment condition set according to the needs of a general user group, or may also be a judgment condition set according to the needs of a special user group. The fault condition is not unique and in actual operation can be adjusted according to the requirements of the user.

For example, taking the working information as the thermoelectric potential of the working combustion area of the inner ring flame 500, and taking the fault condition as that the thermoelectric potential of the working combustion area of the inner ring flame 500 is less than or equal to a first preset threshold (e.g., 4mv), the second detecting element 30 detects the thermoelectric potential of the working combustion area of the inner ring flame 500 and sends the thermoelectric potential to the controller, the controller determines whether the thermoelectric potential is less than or equal to the first preset threshold according to the thermoelectric potential of the working combustion area of the inner ring flame 500, if so, it indicates that the burner 100 may be suddenly extinguished, and in order to avoid a safety accident, the controller controls the gas valve to be closed, so that the inner ring gas and the outer ring gas cannot be injected into the whole burner 100, and thus the safety of the use of the burner 100 can be ensured; if not, the controller controls the inner ring gas valve and the outer ring gas valve to maintain the opening unchanged.

For another example, taking the temperature of the working combustion area of the inner ring flame 500 as the working information and the temperature of the working combustion area of the inner ring flame 500 as the fault condition being less than or equal to the second preset threshold (for example, 20 ℃), the temperature of the working combustion area of the inner ring flame 500 detected by the second detecting element 30 is sent to the controller, the controller determines whether the temperature is less than or equal to the second preset threshold according to the temperature of the working combustion area of the inner ring flame 500, if so, it indicates that the burner 100 may be suddenly extinguished, and in order to avoid a safety accident, the controller controls the gas valve to be closed, so that the inner ring gas and the outer ring gas cannot be injected into the whole burner 100, and thus the safety of the use of the burner 100 can be ensured; if not, the controller controls the inner ring gas valve and the outer ring gas valve to maintain the opening unchanged.

Alternatively, the second sensing member 30 may be a thermocouple for sensing a thermoelectric potential of the operating combustion region of the flame; alternatively, the second sensing member 30 may be a thermistor for sensing the temperature of the working combustion area of the flame.

Further, the combustion main body 10 is provided with an inner ring fire cover 14 and an outer ring fire cover 13, the outer ring fire cover 13 surrounds the circumference of the inner ring fire cover 14 and is arranged at intervals with the inner ring fire cover 14 so as to form a limit space 15 with the inner and outer fire covers, and the second detection piece 30 penetrates through the limit space 15 along the axial direction of the outer ring fire cover 13 and is arranged at intervals with the inner ring cover and the outer ring fire cover 13.

Specifically, the work combustion area of the flame that the second detection piece 30 can detect is located in the limit space 15, and due to the blocking of the outer ring fire cover 13, the work combustion area of the flame that is located in the limit space 15 is less affected by the wind of the external environment, and then when the second detection piece 30 detects the temperature, the thermoelectric force, and the like of the work combustion area of the flame, the stability and the accuracy that the second detection piece 30 detects are both higher, so that the controller can accurately and timely control the combustor 100 to output the appropriate fire.

Further, the second detecting member 30 is disposed in the working combustion region of the inner ring flame 500; the second detection member 30 is configured to detect operation information of an operation combustion area of the inner ring flame 500 in the burner 100 and transmit the operation information to the controller during operation of the burner 100, and the controller controls the gas valve to be closed when a fault condition is satisfied based on the operation information; the working combustion area of the inner ring flame 500 is an area that the inner ring flame 500 can reach when the gas burner 100 is in the sitting state and the away state. The operating information of the operating combustion zone of the inner ring flame 500 includes at least one of a thermoelectric potential of the operating combustion zone of the inner ring flame 500, a temperature of the operating combustion zone of the inner ring flame 500, and a thermal energy radiation intensity of the operating combustion zone of the inner ring flame 500.

Since the inner ring flame 500 is positioned inside the outer ring flame during the operation of the burner 100, the inner ring flame 500 is less affected by external environmental factors (e.g., wind), and the inner ring flame 500 is less prone to swing, thereby having better combustion stability. Therefore, the acquisition of the operation information of the operation combustion region of the inner ring flame 500 is also more accurate. The second detecting member 30 can accurately obtain the operation information of the operation combustion area of the inner ring flame 500 and transmit the operation information to the controller during the operation of the burner 100, and the controller can accurately obtain the operation information of the burner 100 according to the operation information of the operation combustion area of the inner ring flame 500, so that the controller can accurately and timely control the burner 100 to output the appropriate fire power.

The operation of the entire combustor 100 will now be described in detail.

After the burner 100 is started, the first detection part 20 and the second detection part 30 work, the first detection part 20 is used for detecting parameter information of a pot setting combustion area of flame in the burner 100 and sending the parameter information to the controller, and the second detection part 30 is used for detecting working information of the burner 100 and sending the working information to the controller. When the fault condition is satisfied based on the operation information, the controller controls the inner ring gas valve and the outer ring gas valve to be closed, and the burner 100 performs a fire-shutting action. When the no-fault condition is satisfied based on the operation information, the controller controls the inner ring gas valve and the outer ring gas valve to maintain the opening degrees unchanged, and the burner 100 outputs the current fire power. In the working process of the burner 100, the first detection part 20 detects parameter information of a sitting boiler combustion area of flame in the burner 100 and sends the parameter information to the controller, the controller obtains aggregate information of the flame in the burner 100 according to the parameter information of the sitting boiler combustion area of the flame, and when the aggregate information meets a boiler leaving condition, the controller controls a boiler leaving adjustment part corresponding to the boiler leaving condition to execute a first action so as to reduce the firepower output by the burner 100; controlling the burner 100 to maintain the output fire constant when the off-pot condition is not satisfied based on the aggregated information; after the controller performs the first action to reduce the firepower output from the burner 100 by the boiler leaving adjustment device corresponding to the boiler leaving condition, when the boiler leaving condition is not satisfied based on the aggregated information, the burner 100 is controlled to output the firepower larger than that when the boiler leaving adjustment device performs the first action, so that the burner 100 can automatically adjust the firepower in the boiler leaving state and the boiler sitting state, thereby having high operation efficiency and facilitating energy saving and emission reduction.
