Description

Technical Field

[0001] The present invention relates to the technical field of gas stoves, and particularly to a burner structure and a gas stove. Background Art

[0002] The full combustion of the primary mixed gas in a gas stove depends on the sufficient combustion support of the oxygen in the external air by the flame during combustion. The current gas stoves adopt an "upward air intake" combustion method with a multi-layer flame arrangement. During the combustion process, the oxygen content in the air received by the outer flame is sufficient for combustion support, while the air for the central flame is the air that has been used by the outer ring, with a low oxygen content, resulting in a large amount of carbon monoxide, the phenomenon of blackening the bottom of the pot, and a reduction in thermal efficiency.

[0003] In the prior art, the patent "Burner and Gas Stove Having the Same" with the application number 201410710857.2 discloses a gas supplementing device 50. When the temperature sensing device 40 disposed between the central burner cap 31 and the outer ring burner cap 32 senses an increase in temperature, the gas valve body of the gas supplementing device 50 is opened, and the gas valve body is connected to the burner 20. In the description of its specific implementation, it is clearly stated that the gas is first mixed with air in the burner base 10. One end of the gas supplementing device 50 is connected to the temperature sensing device 40, and the other end communicates with the burner base 10. The burner base 10 communicates with the burner 20. As long as the temperature sensing device senses after the flame burns, the gas valve body is opened, and air is supplemented through the two intake pipes 12 of the burner base 10. In fact, it is to increase the proportion of air content during the first mixing of gas and air, but it cannot solve the problem that the air for the inner ring flame is the air that has been used by the outer ring, with a low oxygen content, insufficient combustion support, resulting in a large amount of carbon monoxide and blackening the bottom of the pot.

[0004] The patent "A Gas Stove for Combustion Support and Oil Fume Shielding" with the application number 202010330129.4 provides two annular air guiding rings 5 - 6 between the inner ring burner cap 1 and the outer ring burner cap 2 and outside the outer ring burner cap 2, and uses a fan or a blower to supply air. A ventilation window 13 is provided on the lower cabinet door of the stove. The ventilation window of this stove is set on the cabinet door to meet the air intake requirement.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0028] Embodiment

[0029] See Figure 1 , a burner structure provided by an embodiment of the present invention, as Figure 1 shown, this structure may include:

[0030] A mixed gas supply mechanism, the mixed gas supply mechanism includes a tubular main body 17;

[0031] Wherein, the air outlet of the tubular main body 17 extends to the inside of the inner ring burner cap 3 on the fire distribution base; the tubular main body 17 includes at least two air inlets, and at least two of the air inlets are respectively connected to the first gas supply pipe 21 and the first air supply pipe 15, and a fan 14 is arranged on the first air supply pipe 15.

[0032] The burner structure provided by the embodiment of the present application adds a mixed gas supply mechanism on the basis of not changing the traditional gas stove burner. The mixed gas supply mechanism can mix gas and air and supply it to the central combustion port of the inner ring burner cap, increasing the supplement of mixed air for the central flame, so as to achieve the purpose of improving the combustion efficiency.

[0033] The air inlets of the burners of traditional gas stoves are all arranged below the panel, which makes the oxygen concentration in the air below the panel low. In order to ensure a higher oxygen concentration in the supplied mixed gas and make the combustion more complete, the embodiment of the present application can provide a panel 16. One end of the first air supply pipe away from the tubular main body passes through the panel and extends to the upper part of the panel. The first air supply pipe extracts air from above the panel, so as to ensure that the oxygen content in the extracted air is higher than that in the air below the panel.

[0034] Further, the fire distribution base 2 is formed with an inner ring air outlet 7 and an outer ring air outlet 8, and the inner ring air outlet 7 and the outer ring air outlet 8 are respectively connected to the second gas supply pipe 1. The inner ring air outlet, the outer ring air outlet and the second gas supply pipe can be made by conventional setting methods.

[0035] In practical applications, to facilitate the installation of the gas mixture supply mechanism, an embodiment of the present application can further provide that the distributor seat is formed with a central through hole 9, and the air outlet of the tubular body 17 extends into the interior of the central through hole 9. The central through hole is provided at the center of the distributor seat and is not communicated with the inner ring air outlet. To facilitate the adjustment of the air content in the second gas supply pipe, an embodiment of the present application can further provide that the second gas supply pipe is connected with an air adjustment hole.

[0036] Furthermore, it further includes an ignition needle 12, and the ignition needle 12 is connected to the panel and is located outside the inner ring burner cap. The second gas supply pipe is configured with an electromagnetic valve and a control board, and the ignition needle is electrically connected to the electromagnetic valve and the control board.

[0037] To facilitate the power supply to the fan and the electromagnetic valve, an embodiment of the present application can provide that it further includes a first thermocouple 13 and a second thermocouple 23 provided on the panel. The first thermocouple 13 is connected to the electromagnetic valve, and the second thermocouple 23 is connected to the fan 14. The first thermocouple is located between the inner ring burner cap and the outer ring burner cap, and the second thermocouple is located outside the outer ring burner cap.

[0038] In practical applications, the distributor seat, the gas supply pipe, the barrel body of the gas mixture supply mechanism, the burner air intake port, etc. can be integrally manufactured.

[0039] In the embodiment of the present application, the electromagnetic valve, the gas inlet pipe, the fan, and the air connection pipe are located below the horizontal plane of the panel, and the distributor seat, the central burner cap, the outer ring burner cap, the ignition needle, and the thermocouple are located above the horizontal plane of the panel. The second thermocouple is connected to the fan, and the second thermocouple generates a thermoelectric potential when heated to drive the fan to work.

[0040] In summary, the burner structure provided by the embodiment of the present application has a simple and reasonable structure, and is convenient for installation and use. Through the gas mixture supply mechanism, the air outside the panel can be mixed with the gas and then transmitted to the inside of the inner ring burner cap, and the air can be introduced into the center of the burner from the far end of the panel to assist combustion, improving the thermal efficiency. The central flame burns fully. At the same time, it will not affect the air supply below the burner panel and is worthy of large-scale popularization and use.

[0041] The present application can further provide a gas stove including the above burner structure.

[0042] Specifically, the ignition needle 12 provided in the embodiment of the present application is arranged outside the gas hole 11 of the inner ring burner cap. The ignition needle 12 is connected to the electromagnetic valve and the control board, and the electromagnetic valve is arranged at the front end of the second gas supply pipe 1 and is connected to the gas supply end.

[0043] An air regulating hole 5 for regulating air intake is provided at the front end of the second gas supply pipe 1. The outlet 6 at the rear end of the first gas inlet pipe communicates with the gas outlet of the fire distributing base 2. The fire distributing base 2 is provided with an inner ring gas outlet 7, at least one outer ring gas outlet 8, and a central through hole 9.

[0044] The central through hole 9 is provided at the center of the fire distributing base 2 and is not communicated with the inner ring gas outlet 7.

[0045] A central combustion port 10 is provided at the center of the inner ring burner cap 3, and gas holes 11 are provided on the outside. The gas holes 11 of the inner ring burner cap are communicated with the inner ring gas outlet 7 of the fire distributing base 2.

[0046] The gas holes 11 of the outer ring burner cap 4 are communicated with the outer ring gas outlet 8 of the fire distributing base 2.

[0047] A fan 14 is provided at the burner air inlet 22. The first gas supply pipe 21 is provided with a gas injection port 20 at one end of the tubular main body 17. The air entering through one of the air inlets 22 of the tubular main body is mixed with the gas of the first gas supply pipe 21 inside the tubular main body 17 and then sprayed out through the air outlet 19 of the tubular main body.

[0048] The central combustion port 10 of the inner ring burner cap is communicated with the central through hole 9 of the fire distributing base and the gas-air mixing port.

[0049] A first thermocouple 13 is provided at the outer flame combustion position of the gas holes 11 of the inner ring burner cap 3. The first thermocouple 13 is connected to an electromagnetic valve.

[0050] A second thermocouple 23 is provided at the outer flame combustion position of the gas holes 11 of the outer ring burner cap 4. The second thermocouple 23 is connected to the fan 14. The fan 14 is installed inside the air connection pipe 15. The mixing port of the air connection pipe 15 is communicated with the central through hole 9 of the inner ring burner cap 3. The air inlet end of the air connection pipe 15 is connected to the air inlet 18 of the panel 16.

[0051] As Figure 1 shown, the electromagnetic valve, control board, gas inlet pipe, fan 14, and air connection pipe 15 are located below the horizontal plane of the panel 16, and the fire distributing base 2, inner ring burner cap 3, outer ring burner cap 4, ignition needle 12, and thermocouple are located above the horizontal plane of the panel 16.

[0052] This structure generates a thermoelectric potential due to the heat received by the thermocouple, and generates an electric current in the closed circuit to drive the fan 14. The fan 14 transports the air from the air inlet 18 of the panel through the first air supply pipe 15 to the air outlet 19 of the tubular main body 17. The air with a high oxygen content at the far end of the panel is mixed and burned with the gas at the gas injection port of the tubular main body 17, improving the thermal efficiency and solving the defect that the air with a low oxygen content is likely to produce black smoke (carbon monoxide) during the air mixing of the central flame in the "upward air intake".

[0053] When the gas stove is adjusted to burn with a low flame, the central flame no longer has the obstruction of the outer ring flame. The second mixture of air contains sufficient oxygen content. At this time, the first thermocouple 13 of the outer ring burner cap 4 has no potential difference due to the extinction of the outer ring flame, and the fan 14 also stops working.

[0054] The components above and below the horizontal plane of the panel 14 provided in this application are only relative positions. The thermocouple is set at the flame positions of the inner ring and outer ring burner caps, etc. Those skilled in the art can make advantageous position adjustments, or an air outlet 19 is provided between the inner ring air outlet 7 and the outer ring air outlet 8, and the fan conveys air to between the inner ring air outlet 7 and the outer ring air outlet 8 to assist the combustion of the inner ring flame. The air source conveyed by the fan from other places except the panel, etc. are all inspired by the technology of the present invention. The above are only the preferred embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention are all included in the protection scope of the present invention.
