Description

Technical Field

[0001] The present invention relates to the technical field of burners, and specifically to a burner capable of realizing combustion monitoring and control. Background Technique

[0002] The working principle of the burner is that gas enters the burner head through the gas inlet pipe after being regulated by the gas valve. After the gas is mixed with air, the mixed gas is ejected from the fire holes of the distributor and is ignited by the ignition device to form a flame inside the burner. Currently, most burners are 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 through the damper to control the air-fuel ratio of the gas-air mixture. The air-fuel ratio is the volume ratio of air to gas when the burner burns.

[0003] Most of the existing burners are used indoors (such as in the kitchen). The gas is mixed with the air in the room for combustion. After the burner is used for a long time, the oxygen content in the indoor air decreases due to the consumption of oxygen, and insufficient oxygen supply will cause incomplete combustion of the gas to generate harmful gas carbon monoxide. Therefore, the safety specifications for burner use will remind people to keep the doors and windows open for ventilation indoors to ensure sufficient oxygen content in the indoor air. However, for some elderly people and people with lack of knowledge, most of them do not know that ventilation is required when using the burner, and there is a lack of a device that borrows the ambient air outside the room for combustion control; in addition, the dampers on the existing burners all need to be manually adjusted, and the air-fuel ratio cannot be adjusted in real time according to the specific combustion situation of the gas.

[0010] Preferably, the electric push rod is installed at the rear side of the lower shell, and the telescopic end of the electric push rod is connected to the rear side wall of the movable plate. Both the electric push rod and the motor are electrically connected to the processor through circuits.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] like Figures 1 to 8As shown, the burner in this embodiment can achieve combustion monitoring and control, including a control box 1, a damper assembly 2 and a burner main body 21. The burner main body 21 is an existing structure, consisting of an inner ring, an outer ring and pipes. Both the inner ring and the outer ring are connected to the pipes to form a gas inlet end. Figure 5 The inherent structure of the burner main body 21 is not drawn in Figure 5 . The pipes are two respectively used to introduce the mixed gas into the inner ring and the outer ring. Since the inner ring and the outer ring produce flames simultaneously when the burner main body 21 is in use, the adjusting assembly 57 directly adjusts the two vanes 29 synchronously. An air outlet 3 is opened at the top of the control box 1, and a telescopic pipe 4 is connected to the top of the air outlet 3 for connecting the air outlet 3 and the sealing cover 5, so that the inner cavity of the sealing cover 5 communicates with the control box 1. The top of the telescopic pipe 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. The ventilation cavity 7 is connected to an air inlet pipe 9 and an air outlet pipe 10 to form an air circulation loop. A filter screen 8 is installed inside the ventilation cavity 7. The filter screen 8 is used to filter out the dust and impurities entering from the air inlet pipe 9 to avoid the indoor and outdoor environmental air carrying impurities into it. The air inlet pipe 9 is installed on the side wall of the control box 1 on one side of the ventilation cavity 7, and the air outlet pipe 10 is installed on the side wall of the control box 1 on the other side of the ventilation cavity 7. The bottom of the control box 1 is connected to a support leg 11. 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 the flame color. A sealing door 14 is connected to the front side of the control box 1. The sealing door 14 is used to close the control box 1. 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. Both the upper shell 52 and the lower shell 51 are semi-box-shaped with a hollow interior. On the left and right sides of the upper shell 52 and the lower shell 51, there are integrally connected side ears 53. On the side where the upper shell 52 and the lower shell 51 are close to each other, there is a sealing gasket 54. The sealing gasket 54 is made of a temperature-resistant elastic material for close fitting when the upper shell 52 and the lower shell 51 are combined. An installation hole 55 is penetrated through the side ear 53, and a bolt 56 is penetrated through the installation hole 55. The upper shell 52 and the lower shell 51 are combined and connected by borrowing the bolt 56 to achieve the effect of quick disassembly and assembly of the upper shell 52 and the lower shell 51. An adjusting assembly 57 is installed inside the lower shell 51 for adjusting the air intake of the damper assembly 2. An air inlet 58 is opened at the bottom of the lower shell 51 for connecting the telescopic pipe 4 and the inner cavity of the sealing cover 5.

[0024] Specifically, an infrared detection probe 131 and a ultraviolet detection probe 132 are electrically connected to the rear side of the flame detector 13. 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 main body 21, ensuring that the distances between the infrared detection probe 131 and the ultraviolet detection probe 132 and the burner main 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 main 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. Since the flame of normal combustion is blue, the ultraviolet wavelength of the blue flame is greater than the infrared wavelength, while the flames of abnormal combustion are yellow or red, and the infrared wavelengths of the yellow and red flames are greater than the ultraviolet wavelength. Therefore, the infrared and ultraviolet wavelengths are collected by the infrared detection probe 131 and the ultraviolet detection probe 132, and the data is transmitted to the flame detector 13. The flame detector 13 calculates the difference between the infrared and ultraviolet rays. After the difference reaches the preset range value, it can be determined whether the flame is blue, yellow or red 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 has disappeared.

[0025] Furthermore, the left and right sides of the ventilation cavity 7 communicate with the air inlet pipe 9 and the air outlet pipe 10 respectively. Both the air inlet pipe 9 and the air outlet pipe 10 use corrugated pipes. The ends of the air inlet pipe 9 and the air outlet pipe 10 far from the control box 1 extend to the inside and outside of the room 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 outside. The air inlet pipe 9, the air outlet pipe 10 and the ventilation cavity 7 form an air circulation loop, enabling the indoor and outdoor air to circulate in the ventilation cavity 7. The top of the ventilation cavity 7 is connected to the telescopic pipe 4 through the air outlet 3. The telescopic pipe 4 is connected to the inner cavity of the sealing cover 5 through the air inlet 58. The telescopic pipe 4 connects the ventilation cavity 7 and the sealing cover 5. The sealing cover 5 covers the outside of the damper assembly 2, allowing the air outside the room to enter the sealing cover 5 from the telescopic pipe 4 and then pass through the damper to be mixed with the gas, achieving the effect of mixing the ambient air outside the room with the gas, providing a sufficient oxygen-containing environment for gas combustion, enabling the burner to be safely used in a room without ventilation, and avoiding the situation that some elderly people and people with lack of knowledge use the burner without opening the window, resulting in incomplete gas combustion and carbon monoxide poisoning.

[0026] Further, the adjusting component 57 includes two fixing plates 571 mounted on the inner wall of the lower housing 51. Both of the two fixing plates 571 are provided with sliding grooves 572 inside. A slider 573 is slidably connected inside both of the two sliding grooves 572. The longitudinal section of the slider 573 is in an L shape. The slider 573 is stuck inside the sliding groove 572 and slides. The upper surfaces of the two sliders 573 are jointly connected with a movable plate 574. The movable plate 574 can move back and forth relative to the fixing plate 571 through the slider 573. An activity groove 575 is provided inside the movable plate 574. Two movable blocks 576 are slidably connected inside the activity groove 575. A screw hole 577 is penetrated through the middle of both of the two movable blocks 576. A screw rod 578 is penetrated through both of the two screw holes 577. The thread directions inside both of the two screw holes 577 are the same. When the screw rod 578 rotates, it drives the two movable blocks 576 to move in the same direction through the screw holes 577, so that the movable blocks 576 drive the two dial blocks 5711 to move in the same direction, and at the same time adjust the two dial pieces 29. Bearings 579 are installed between both ends of the screw rod 578 and the side wall of the movable plate 574. One end of the screw rod 578 extends out from the side wall of the movable plate 574 and is connected with a motor 5710. The motor 5710 is installed on the side wall of the movable plate 574. The center of the rear side wall of the movable plate 574 is connected with an electric push rod 5714. In practical applications, if the motor 5710 and the electric push rod 5714 are not temperature-resistant, a heat insulation cover can be sleeved outside the motor 5710 and the electric push rod 5714 to avoid the influence of the heat generated by the gas combustion on the burner main body 21.

[0027] Further, the movable plate 574 forms a sliding connection with the two fixing plates 571 through the slider 573. One side of the movable plate 574 close to the motor 5710 extends out from the side wall of the lower housing 51. A rectangular groove for the movable plate 574 to extend out and move back and forth is provided on the side wall of the lower housing 51. And in order to prevent air leakage between the movable plate 574 and the sealing cover 5, elastic sealing members are connected between both sides of the movable plate 574 and the rectangular groove. The screw rod 578 penetrates through the screw hole 577 and forms a threaded connection with the two movable blocks 576. The two movable blocks 576 form a sliding connection with the movable plate 574. By rotating the screw rod 578, the two movable blocks 576 are driven to move horizontally in the activity groove 575. The movable blocks 576 drive the dial blocks 5711 to move. The dial blocks 5711 exert a horizontal pushing force on the dial pieces 29 inserted inside them, so that the dial pieces 29 drive the baffle 23 to rotate relative to the fixed rod, and the air intake of the burner main body 21 is adjusted to further adjust the air-fuel ratio.

[0028] 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, and the movable plate 574 drives the shift block 5711 to move 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 from the iron sheet 22. The paddle 29 is pulled out from the positioning hole 28 to cancel the limiting effect of the positioning hole 28 on the paddle 29. 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.

[0029] Furthermore, the damper assembly 2 includes an iron sheet 22 installed at 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 pipeline 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 through the baffle 23 and the iron sheet 22. By shifting the baffle 23 to rotate 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 pipeline 26. When the positioning protrusion is pushed 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 a moving space for the baffle 23. A plurality of positioning holes 28 are provided, and a paddle 29 is integrally connected to the bottom of the baffle 23. The damper assembly 2 is an existing structure, and the sealing cover 5 can be directly installed on the existing damper assembly 2 for combustion control. When the intersection area between the iron sheet 22 and the through hole 24 on the baffle 23 is small, the air intake amount 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 flame is yellow or red due to insufficient air volume, and this 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 this state is set to the normal combustion mode.

[0030] Further, a dial block 5711 is connected to the upper surface of the movable block 576. A slot 5712 is formed inside the dial block 5711. An elastic pad 5713 is installed on the inner wall of the slot 5712. The elastic pad 5713 is made of a temperature-resistant elastic material. After the dial piece 29 is inserted into the slot 5712, the elastic pad 5713 is used to fill the gap between the dial piece 29 and the dial block 5711. A positioning protrusion adapted to the inner diameter of the positioning hole 28 is provided on the rear side wall of the dial piece 29. The positioning protrusion is movably inserted into the positioning hole 28. In the prior art, the positioning protrusion is inserted into the positioning hole 28 to maintain the stability of the retaining piece 23. The width dimension of the dial piece 29 matches the width dimension of the slot 5712. The dial piece 29 is movably inserted into the dial block 5711 through the slot 5712. By inserting the dial piece 29 into the dial block 5711, when the dial block 5711 moves forward and backward and left and right, the dial piece 29 is driven to move together.

[0031] Furthermore, a first groove 511 is jointly formed in the front side walls of the upper housing 52 and the lower housing 51, and a second groove 512 is jointly formed in the rear side walls of the upper housing 52 and the lower housing 51. The sizes of the first groove 511 and the second groove 512 can be customized according to the actual sizes of different models of the burner main body 21, so that the upper housing 52 and the lower housing 51 can be smoothly installed outside the damper assembly 2. The bolts 56 sequentially pass through the side ears 53 on the upper housing 52 and the lower housing 51 through the mounting holes 55. The upper housing 52 and the lower housing 51 are combined and connected by the bolts 56 and cover the outside of the damper assembly 2. The gas pipeline 26 passes through the front side walls of the upper housing 52 and the lower housing 51 through the first groove 511, and the burner main body 21 passes through the rear side walls of the upper housing 52 and the lower housing 51 through the second groove 512, so that the sealing cover 5 can be directly installed on the existing burner for use.

[0032] The usage method of this embodiment is as follows: When the user actually controls the combustion of the burner used indoors, first place the upper housing 52 and the lower housing 51 on the upper and lower sides of the air damper assembly 2 respectively. Insert the paddle 29 at the bottom of the baffle 23 into the slot 5712 of the dial block 5711. Then, pass the bolts 56 through the side ears 53 of the upper housing 52 and the lower housing 51 in sequence, and connect the upper housing 52 and the lower housing 51 by the bolts 56. Adjust the front and rear positions of the upper housing 52 and the lower housing 51 to ensure that the burner body 21 is stuck in the second groove 512 and the gas pipeline 26 is stuck in the first groove 511. The gasket 54 seals the gaps between the upper housing 52, the lower housing 51, the burner body 21, and the gas pipeline 26. Then, place the control box 1 in the stove cabinet under the burner body 21, and install the infrared detection probe 131 and the ultraviolet detection probe 132 on one side of the burner body 21, keeping 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 pipes 9 and the air outlet pipes 10 on both sides of the control box 1 through the indoor wall to communicate with the indoor and outdoor environments. 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. The electric push rod 5714 extends to push the movable plate 574 to move forward on the fixed plate 571. The movable plate 574 drives the dial block 5711 to move forward through the movable block 576. The dial block 5711 exerts a forward thrust on the paddle 29 inserted into it, causing the paddle 29 to drive the positioning protrusion to be pulled out of the positioning hole 28 on the iron sheet 22, canceling the limiting effect of the positioning hole 28 on the paddle 29. Then, the motor 5710 drives the screw rod 578 to rotate. The screw rod 578 drives the two movable blocks 576 to move to one side in the movable groove 575 through the screw holes 577. The movable blocks 576 drive the dial block 5711 to move. The dial block 5711 exerts a lateral pushing effect on the paddle 29 inserted into it, causing the paddle 29 to drive the baffle 23 to rotate towards one side relative to the fixed rod, reducing the air intake volume, making the gas concentration greater than the air concentration to start the initial ignition mode. During use, the air inlet pipes 9, the air outlet pipes 10, and the ventilation cavity 7 form an air circulation loop. The indoor and outdoor air circulates in the ventilation cavity 7 and then enters the sealing cover 5 through the telescopic tube 4. The gas in the gas pipeline 26 is mixed with the external environment air introduced into the sealing cover 5 and then leads to the burner body 21 to be ignited by the ignition device for combustion. When the gas burns, a flame appears. The flame generates infrared and ultraviolet light rays. The infrared detection probe 131 and the ultraviolet detection probe 132 respectively detect the wavelengths of the infrared and ultraviolet light rays 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 turns on the combustion mode, controls the electric push rod 5714 and the motor 5710 to start, and increases the air intake volume of the air damper assembly 2 to keep the gas concentration and the air concentration in balance.When the gas burns insufficiently 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 ray and the ultraviolet ray reaches the preset range value, and the flame detector 13 inputs a signal to the processor 12. The processor 12 controls the electric push rod 5714 and the motor 5710 to start, and increases the air intake of the air door assembly 2 again until the flame returns to normal blue.
