Description
Technical Field
[0001] The present invention relates to the technical field of burners, in particular to a burner capable of realizing combustion monitoring and control. Background Art
[0002] The working principle of the burner is that the gas enters the burner from the air inlet pipe through the gas valve adjustment. After the gas and air are mixed, the mixed gas is ejected from the fire hole of the ignition distributor and ignited by the ignition device to form a flame in the burner. At present, the burner is mostly composed of an inner ring and an outer ring. A damper is installed at the gas inlet of the inner ring and the outer ring respectively. The air intake volume is adjusted by the damper to control the air-fuel ratio of the gas and air mixture. The air-fuel ratio is the volume ratio of air to gas when the burner is burning.
[0003] Existing burners are mostly used indoors (such as in kitchens), where gas mixes with the indoor air for combustion. After prolonged use, the oxygen content in the indoor air decreases, and insufficient oxygen supply causes incomplete combustion of the gas, producing harmful carbon monoxide. Therefore, burner safety regulations remind people to open doors and windows for ventilation to maintain sufficient oxygen in the indoor air. However, many elderly people and those with limited knowledge are unaware of the need for ventilation during burner operation, lacking a device that utilizes ambient air outside the room for combustion control. Furthermore, existing burner dampers require manual adjustment, making it impossible to adjust the air-to-fuel ratio in real time based on the specific combustion conditions. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] The burner capable of realizing combustion monitoring and control is provided with a ventilation cavity, an air inlet pipe and an air outlet pipe. By extending one end of the air inlet pipe and the air outlet pipe away from the control box to the indoor and outdoor sides and communicating with the external environment, the air inlet pipe, the air outlet pipe and the ventilation cavity form an air circulation loop, so that the air from indoor and outdoor sides circulates in the ventilation cavity. The ventilation cavity and the sealing cover are connected by a telescopic tube. The sealing cover is covered on the outside of the damper assembly. The air from indoor and outdoor sides enters the sealing cover through the telescopic tube and passes through the damper to mix with the gas, so that the ambient air from indoor and outdoor sides is mixed with the gas, thereby providing a sufficient oxygen-containing environment for gas combustion, so that the burner can be used safely even in a room without ventilation.
[0017] The burner capable of realizing combustion monitoring and control is provided with an adjusting component. When the air door needs to be adjusted, the electric push rod is first extended to push the movable plate forward on the fixed plate, and the movable plate drives the dial block to move forward through the movable block, and the dial block applies a forward thrust to the dial piece inserted inside it, so that the dial piece drives the positioning protrusion to be pulled out from the positioning hole on the iron plate, canceling the limiting effect of the positioning hole on the dial piece, and then the screw is driven by the motor to rotate, and the screw drives the two movable blocks to move horizontally in the movable groove through the screw hole, and the movable block drives the dial block to move, and the dial block applies a horizontal pushing effect to the dial piece inserted inside it, so that the dial piece drives the baffle to rotate relative to the fixed rod, thereby adjusting the air intake amount of the burner body and thus adjusting the air-fuel ratio. The air-fuel ratio is adjusted according to actual conditions to ensure effective combustion of the gas and avoid wasting gas resources. In view of the limiting effect of the baffle on the baffle by the existing air door structure, the dial piece is automatically driven to move in the horizontal and vertical directions, and the air intake amount of the air door is adjusted according to actual conditions.
[0018] The burner capable of realizing combustion monitoring and control is provided with a sealing cover, and the upper shell and the lower shell are respectively covered above and below the sealing door assembly, and the upper shell and the lower shell are assembled and connected by bolts passing through the mounting holes, so that the sealing cover can be quickly installed.

[0032] like Figures 1 to 8As shown, the burner of this embodiment can realize combustion monitoring and control, including a control box 1, a damper assembly 2 and a burner body 21. The burner body 21 is an existing structure, consisting of an inner ring, an outer ring and a pipe. The inner ring and the outer ring are connected to the pipe to form a gas inlet end. Figure 5 The inherent structure of the burner body 21 is not drawn in the figure. There are two pipes for respectively passing the mixed gas into the inner ring and the outer ring. Since the inner ring and the outer ring ignite at the same time when the burner body 21 is in use, the adjustment component 57 directly adjusts the two paddles 29 synchronously. An air outlet 3 is provided on the top of the control box 1. A telescopic tube 4 is connected to the top of the air outlet 3 to connect the air outlet 3 and the sealing cover 5 so that the inner cavity of the sealing cover 5 is communicated with the control box 1. The top of the telescopic tube 4 is connected to the sealing cover 5. A partition 6 is installed inside the control box 1 to separate the inner cavity of the control box 1. The inner cavity of the control box 1 above the partition 6 forms a ventilation cavity 7, which is connected to the air inlet pipe 9 and An air outlet pipe 10 forms an air circulation loop, and a filter 8 is installed inside the ventilation cavity 7. The filter 8 is used to filter out dust and impurities entering the air inlet pipe 9 to prevent the indoor and outdoor ambient air from carrying impurities into the air. An air inlet pipe 9 is installed on the side wall of the control box 1 on one side of the ventilation cavity 7, and an air outlet pipe 10 is installed on the side wall of the control box 1 on the other side of the ventilation cavity 7. A support leg 11 is connected to the bottom of the control box 1. A processor 12 is installed inside the control box 1 below the partition 6. The input end of the processor 12 is electrically connected to a flame detector 13 for detecting the flame combustion state and flame color. A sealing door 14 is connected to the front side of the control box 1, and the sealing door 14 is used to close the control box 1;
[0033] The sealing cover 5 includes an upper shell 52 and a lower shell 51 installed on the upper and lower sides of the damper assembly 2. The upper shell 52 and the lower shell 51 are both semi-box-shaped with a hollow interior. The left and right sides of the upper shell 52 and the lower shell 51 are integrally connected with side ears 53. The side where the upper shell 52 and the lower shell 51 are close to each other is provided with a sealing gasket 54. The sealing gasket 54 is made of temperature-resistant elastic material and is used to fit tightly when the upper shell 52 and the lower shell 51 are combined. A mounting hole 55 is opened through the side ear 53, and a bolt 56 is opened through the mounting hole 55. The upper shell 52 and the lower shell 51 are combined and connected by the bolt 56 to achieve the effect of quick disassembly and assembly of the upper shell 52 and the lower shell 51. An adjusting component 57 is installed inside the lower shell 51 for adjusting the air intake amount of the damper assembly 2. An air inlet 58 is opened at the bottom of the lower shell 51 for connecting the telescopic tube 4 with the inner cavity of the sealing cover 5.
[0034] Specifically, the rear side of the flame detector 13 is electrically connected to an infrared detection probe 131 and an ultraviolet detection probe 132. The actual models of the infrared detection probe 131 and the ultraviolet detection probe 132 are selected according to the actual distance between their installation positions and the burner body 21, ensuring that the distances between the infrared detection probe 131 and the ultraviolet detection probe 132 and the burner body 21 are within their detection ranges. The infrared detection probe 131 and the ultraviolet detection probe 132 are installed on one side of the burner body 21. The infrared detection probe 131 detects the infrared wavelength of the flame, and the ultraviolet detection probe 132 detects the ultraviolet wavelength of the flame. External wavelength: Since the flame of normal burning is blue flame, the ultraviolet wavelength of blue flame is greater than the infrared wavelength, and the flame of abnormal burning is yellow flame or red flame, the infrared wavelength of yellow flame and red flame is greater than the ultraviolet wavelength, so the infrared detection probe 131 and the ultraviolet detection probe 132 collect the infrared and ultraviolet wavelengths, and transmit the data to the flame detector 13. The flame detector 13 calculates the difference between the infrared and ultraviolet rays. After the difference between the two reaches the preset range value, it can be judged whether the flame is blue flame, yellow flame, or red flame at this time, and then the gas combustion state can be judged. In addition, when the infrared and ultraviolet wavelengths disappear, it can be judged that the flame disappears.
[0035] Furthermore, the left and right sides of the ventilation cavity 7 are respectively connected with the air inlet pipe 9 and the air outlet pipe 10, and the air inlet pipe 9 and the air outlet pipe 10 are both bellows. The air inlet pipe 9 and the air outlet pipe 10 extend to the indoor and outdoor sides away from the control box 1 and communicate with the external environment. In actual application, it is best to pass the air inlet pipe 9 and the air outlet pipe 10 through the indoor wall to the outdoors. The air inlet pipe 9, the air outlet pipe 10 and the ventilation cavity 7 form an air circulation loop, so that the indoor and outdoor air circulate in the ventilation cavity 7. The top of the ventilation cavity 7 is connected with the telescopic pipe 4 through the air outlet 3, and the telescopic pipe 4 is connected to the air inlet 5. 8 is communicated with the inner cavity of the sealing cover 5, and the ventilation cavity 7 and the sealing cover 5 are connected by the telescopic tube 4. The sealing cover 5 is covered on the outside of the damper assembly 2, so that the air inside and outside the room can enter the sealing cover 5 from the telescopic tube 4 and then pass through the damper to mix with the gas, thereby achieving the effect of mixing the ambient air inside and outside the room with the gas, providing a sufficient oxygen-containing environment for gas combustion, so that the burner can be used safely in an unventilated room, avoiding the situation where some elderly people and people with lack of knowledge use the burner without opening the window, resulting in incomplete gas combustion and causing carbon monoxide poisoning.
[0036] Furthermore, the adjustment assembly 57 includes two fixed plates 571 mounted on the inner wall of the lower shell 51, and the two fixed plates 571 are provided with a sliding groove 572. The two sliding grooves 572 are slidably connected with a slider 573. The longitudinal section of the slider 573 is L-shaped. The slider 573 slides in the sliding groove 572. The upper surfaces of the two sliders 573 are commonly connected with a movable plate 574. The movable plate 574 can move back and forth relative to the fixed plate 571 through the slider 573. A movable groove 575 is provided inside the movable plate 574. Two movable blocks 576 are slidably connected inside the movable groove 575. Screw holes 577 are provided in the middle of the two movable blocks 576. A screw rod 578 is commonly provided inside the two screw holes 577. The thread directions of the two parts are consistent. When the screw 578 rotates, the two movable blocks 576 are driven to move in the same direction through the screw hole 577, so that the movable block 576 drives the two shift blocks 5711 to move in the same direction, and the two shift pieces 29 are adjusted at the same time. Bearings 579 are installed between the two ends of the screw 578 and the side walls of the movable plate 574. One end of the screw 578 extends from the side wall of the movable plate 574 and is connected to a motor 5710. The motor 5710 is installed on the side wall of the movable plate 574. An electric push rod 5714 is connected to the center of the rear side wall of the movable plate 574. In actual application, if the motor 5710 and the electric push rod 5714 are not heat-resistant, a heat insulation cover can be installed on the outside of the motor 5710 and the electric push rod 5714 to avoid the heat influence of the gas combustion on the burner body 21.
[0037] Furthermore, the movable plate 574 is slidably connected with the two fixed plates 571 through the slider 573, and the side of the movable plate 574 close to the motor 5710 extends from the side wall of the lower shell 51. The side wall of the lower shell 51 is provided with a rectangular groove for the movable plate 574 to extend and move back and forth. In order to avoid air leakage between the movable plate 574 and the sealing cover 5, elastic sealing members are connected between the two sides of the movable plate 574 and the rectangular groove. The screw 578 passes through the screw hole 577 and forms a threaded connection with the two movable blocks 576. The two movable blocks 576 are slidably connected with the movable plate 574. The two movable blocks 576 are driven to move horizontally in the movable groove 575 by the rotation of the screw 578. The movable block 576 drives the shift block 5711 to move. The shift block 5711 exerts a lateral pushing effect on the shift piece 29 inserted therein, so that the shift piece 29 drives the baffle 23 to rotate relative to the fixed rod, thereby adjusting the air intake amount of the burner body 21 and thus adjusting the air-fuel ratio.
[0038] Furthermore, the electric push rod 5714 is installed on the rear side of the lower housing 51, and the telescopic end of the electric push rod 5714 is connected to the rear side wall of the movable plate 574. The electric push rod 5714 is extended to push the movable plate 574 forward on the fixed plate 571. The movable plate 574 drives the shift block 5711 forward through the movable block 576. The shift block 5711 applies a forward thrust to the shift piece 29 inserted therein, so that the shift piece 29 drives the positioning protrusion to move out of the iron sheet 22. The movable plate 574 is pulled out from the positioning hole 28, and the limiting effect of the positioning hole 28 on the paddle 29 is cancelled. After the screw 578 drives the paddle block 5711 to move the paddle 29 laterally, the electric push rod 5714 contracts and pulls the movable plate 574 backward to reset. The positioning protrusion on the rear side of the paddle 29 is reinserted into the positioning hole 28. The electric push rod 5714 and the motor 5710 are electrically connected to the processor 12 through the circuit and are controlled by the processor 12 to realize automatic adjustment of the damper assembly 2.
[0039] Furthermore, the damper assembly 2 includes an iron sheet 22 mounted on the air inlet end of the burner body 21, a fixed tube 25 is connected to the center of one side of the iron sheet 22, and a gas pipe 26 is connected to the end of the fixed tube 25 away from the iron sheet 22. A baffle 23 is movably sleeved on the outer side of the fixed tube 25 on one side of the iron sheet 22, and a through hole 24 is penetrated on the baffle 23 and the iron sheet 22. By rotating the baffle 23 relative to the fixed tube 25, the baffle 23 and the through hole 24 on the iron sheet 22 are staggered to achieve the effect of adjusting the air intake volume. A spring 27 is sleeved on the outer side of the fixed tube 25 between the baffle 23 and the gas pipe 26. When the positioning protrusion is pulled out of the positioning hole 28, the paddle 29 drives the baffle 23 to move toward the side away from the iron sheet 22, and the spring 27 contracts to provide moving space for the baffle 23. There are several positioning holes 28, and the bottom of the baffle 23 is integrally connected with a paddle 29. The damper assembly 2 is an existing structure. The sealing cover 5 can be directly installed on the existing damper assembly 2 for combustion control. When the intersection area of the iron sheet 22 and the through hole 24 on the baffle 23 is small, the air intake becomes less. At this time, the gas concentration is greater than the air concentration, and this state is set to the initial ignition mode. After the burner body 21 is closed, the flame detector 13 detects that the flame disappears, and the processor 12 controls the adjustment component 57 to adjust the damper assembly 2 to put it in the ignition mode. After the ignition is completed and the flame appears, the air volume is insufficient and the flame is yellow or red. The state is positioned as the insufficient combustion mode. The processor 12 controls the adjustment component 57 to adjust the air intake of the damper assembly 2 to increase until the flame is normal blue, and the state is set to the normal combustion mode.
[0040] Furthermore, a shift block 5711 is connected to the upper surface of the movable block 576, and a slot 5712 is provided inside the shift block 5711. An elastic pad 5713 is installed on the inner wall of the slot 5712. The elastic pad 5713 is made of temperature-resistant elastic material. After the shift piece 29 is inserted into the slot 5712, the elastic pad 5713 is used to fill the gap between the shift piece 29 and the shift block 5711. A positioning protrusion that is adapted to the inner diameter of the positioning hole 28 is provided on the rear side wall of the shift piece 29. The positioning protrusion is movably connected to the positioning hole 28. In the prior art, the positioning protrusion is connected to the positioning hole 28 to maintain the stability of the baffle 23. The width of the shift piece 29 matches the width of the slot 5712. The shift piece 29 is movably connected to the shift block 5711 through the slot 5712. When the shift block 5711 moves forward and backward and left and right, the shift piece 29 is driven to move together.
[0041] Furthermore, the upper shell 52 and the lower shell 51 have a common front side wall with a first groove 511, and the upper shell 52 and the lower shell 51 have a common rear side wall with a second groove 512. The sizes of the first groove 511 and the second groove 512 can be customized according to the actual sizes of the burner body 21 of different models, so that the upper shell 52 and the lower shell 51 can be smoothly installed on the outside of the damper assembly 2. The bolts 56 pass through the side ears 53 on the upper shell 52 and the lower shell 51 in sequence through the mounting holes 55. The upper shell 52 and the lower shell 51 are connected in combination by the bolts 56 and covered on the outside of the damper assembly 2. The gas pipeline 26 passes through the upper shell 52 and the front side wall of the lower shell 51 through the first groove 511, and the burner body 21 passes through the upper shell 52 and the rear side wall of the lower shell 51 through the second groove 512, so that the sealing cover 5 can be directly installed on the existing burner for use.
[0042] The method of using this embodiment is as follows: when the user actually controls the combustion of the burner used indoors, first, the upper shell 52 and the lower shell 51 are placed on the upper and lower sides of the damper assembly 2 respectively, the paddle 29 at the bottom of the baffle 23 is inserted into the slot 5712 of the paddle block 5711, and then the bolts 56 are passed through the side ears 53 of the upper shell 52 and the lower shell 51 in sequence, and the upper shell 52 and the lower shell 51 are assembled and connected by the bolts 56, and the front and rear positions of the upper shell 52 and the lower shell 51 are adjusted to ensure that the burner body 21 is stuck in the second groove 512 and the gas pipe 26 is stuck in the first groove 511, and the gaps between the upper shell 52, the lower shell 51 and the burner body 21 and the gas pipe 26 are sealed by the sealing gasket 54, and then Place the control box 1 in the kitchen cabinet below the burner body 21, install the infrared detection probe 131 and the ultraviolet detection probe 132 on one side of the burner body 21, keep the monitoring directions of the infrared detection probe 131 and the ultraviolet detection probe 132 facing the burner body 21, then connect the telescopic tube 4 at the bottom of the sealing cover 5 to the air outlet 3, and pass the air inlet pipe 9 and the air outlet pipe 10 on both sides of the control box 1 through the indoor wall to connect with the indoor and outdoor environment. After the control box 1 is connected to the power supply, the processor 12 outputs a signal to control the motor 5710 and the electric push rod 5714 to start, and the electric push rod 5714 extends to push the movable plate 574 forward on the fixed plate 571, and the movable plate 574 drives the shift block 5711 to move forward through the movable block 576, and the shift block 57 11 applies a forward thrust to the paddle 29 inserted therein, so that the paddle 29 drives the positioning protrusion to be pulled out from the positioning hole 28 on the iron sheet 22, canceling the limiting effect of the positioning hole 28 on the paddle 29, and then the motor 5710 drives the screw 578 to rotate, and the screw 578 drives the two movable blocks 576 to move to one side in the movable groove 575 through the screw hole 577, and the movable block 576 drives the paddle block 5711 to move, and the paddle block 5711 applies a lateral pushing effect to the paddle 29 inserted therein, so that the paddle 29 drives the baffle 23 to rotate to one side relative to the fixed rod, reducing the air intake, making the gas concentration greater than the air concentration to start the initial ignition mode. When in use, the air inlet pipe 9, the air outlet pipe 10 and the ventilation cavity 7 form an air circulation circuit. The indoor and outdoor air circulates in the ventilation cavity 7, and then enters the sealed cover 5 through the telescopic tube 4. The gas in the gas pipe 26 mixes with the external ambient air introduced into the sealed cover 5, and then flows into the burner body 21 to be ignited by the ignition device for combustion. When the gas burns, a flame appears, and the flame generates infrared and ultraviolet rays. The infrared detection probe 131 and the ultraviolet detection probe 132 respectively detect the infrared and ultraviolet wavelengths of the flame, and transmit the data to the flame detector 13. The flame detector 13 inputs a flame signal to the processor 12. After receiving the signal, the processor 12 starts the combustion mode, controls the electric push rod 5714 and the motor 5710 to start, increases the air intake of the damper assembly 2, and keeps the gas concentration and the air concentration in balance.When the gas combustion is incomplete and the flame appears yellow or red, the infrared detection probe 131 and the ultraviolet detection probe 132 detect that the difference between the infrared and ultraviolet rays reaches the preset range value. The flame detector 13 inputs a signal to the processor 12, which controls the electric push rod 5714 and the motor 5710 to start, and increases the air intake of the damper assembly 2 again until the flame returns to its normal blue color.
