Referring to fig. 1,2 and 3, the present application provides a burner 100, wherein the burner 100 is used for heating a cooking appliance. The burner 100 comprises a combustion main body 10 and an ionization piece 20, wherein a plurality of combustion holes 11 which can be used for combustion of fuel gas are formed in the combustion main body 10, the ionization piece 20 is connected to the combustion main body 10 in a matching mode, the ionization piece comprises a plurality of ionization parts 21, the ionization parts 21 are in one-to-one correspondence with the combustion holes 11, each ionization part 21 is arranged in the corresponding combustion hole 11 in a penetrating mode and is arranged at intervals with the wall of the corresponding combustion hole 11, and potential differences which can ionize the fuel gas and generate active groups (such as O, H, CH, O3 and NO) exist between each ionization part 21 and the wall of the corresponding combustion hole 11.

When the burner 100 is operated, the gas flows into each combustion hole 11 and burns in each combustion hole 11, and heat generated by the combustion is transferred to the cooking appliance through the combustion body 10 and the air convection manner, and heats the cooking appliance. Because of the potential difference, the fuel gas introduced into each fuel gas hole can be ionized under the action of the potential difference and generate active groups. The active groups can mix with and support combustion of the fuel gas so that the fuel gas can be fully combusted, so that the thermal efficiency of the burner 100 can be effectively improved. In addition, the reactive groups can react with harmful gases (e.g., carbon monoxide) formed after combustion of the fuel gas and generate harmless gases (e.g., carbon dioxide), thereby providing the burner 100 with better environmental protection performance. Further, since the combustion and ionization of the gas are both performed in the combustion hole 11, the high temperature generated in the combustion process can also promote ionization and generate active groups with higher concentration, so that the combustion of the gas can also be better promoted and the emission of harmful gases is less, and therefore, the burner 100 has higher thermal efficiency and better environmental protection performance.

Specifically, the gas in each combustion hole 11 may be ignited by an ignition needle additionally provided on the burner 100, or may be ignited by the combined action of the ionization member 20 and the combustion body 10. Preferably, the combustion gases in each combustion bore 11 are ignited by the combined action of the ioniser 20 and the combustion body 10. In this way, the trouble of providing the ignition needle can be reduced, thereby making the structure of the burner 100 simpler and the manufacturing cost lower. Specifically, before the gas in each combustion hole 11 is not ignited, the potential difference between each ionization section 21 and the wall of the corresponding combustion hole 11 is controlled to be a potential difference capable of igniting the gas so that the gas in each combustion hole 11 can be ignited. Then, the potential difference between each ionization part 21 and the wall of the corresponding combustion hole 11 is controlled to be a potential difference capable of ionizing the fuel gas and generating active groups so as to ionize the fuel gas.

Referring to fig. 4, specifically, each ionization part 21 may be electrically connected to a high-voltage positive electrode, the combustion body 10 may be electrically connected to a high-voltage negative electrode, or each ionization part 21 may be electrically connected to a high-voltage negative electrode, and the combustion body 10 may be electrically connected to a high-voltage positive electrode. Preferably, the combustion body 10 and the ionization member 20 are both conductive members (e.g., metal), each ionization portion 21 is electrically connected to an external high-voltage positive electrode, and the combustion body 10 is grounded, so that a potential difference of ionized gas can be formed between each ionization portion 21 and the wall of the corresponding combustion hole 11. It should be appreciated that grounding of the combustion body 10 may be accomplished by directly carrying the combustion body 10 on an external mounting surface (e.g., the ground, or a table top). Since the combustion body 10 is located outside the ionization member 20, the manner of directly placing the combustion body 10 on the mounting surface for grounding and electrically connecting the ionization portion 21 with the high-voltage positive electrode to form a potential difference is simpler and more convenient to operate.

More specifically, the combustion body 10 is provided with a plurality of connection holes (not shown), which are in one-to-one correspondence with the plurality of combustion holes 11, and each connection hole penetrates the combustion body 10 in the radial direction of the combustion body 10 and is communicated between the corresponding combustion hole 11 and the outside. The burner 100 further includes a plurality of conductive members 7, where the plurality of conductive members 70 are in one-to-one correspondence with the plurality of connection holes, and each conductive member 70 is inserted into the corresponding connection hole and connected between the corresponding ionization portion 21 and the high-voltage positive electrode, so as to realize electrical connection between the high-voltage electrode and the ionization portion 21. To prevent each ionization section 21 from being electrically connected to the combustion body 10 to be short-circuited, it is necessary to ensure that each ionization section 21 is not in contact with the combustion body 10 and that an insulating material is coated on the surface of each conductive member 70 to separate the combustion body 10 from the conductive member 70.

Each ionization part 21 is defined to have a plurality of ionization position points, all ionization position points on each ionization part 21 are combined to form the outer surface of the ionization part 21, the hole wall of each combustion hole 11 is defined to have a plurality of combustion position points, and all combustion position points on the hole wall of each combustion hole 11 are combined to form the hole wall of the combustion hole 11. Each ionization part 21 is arranged in the corresponding combustion hole 11 in a penetrating way, and potential difference exists between the walls of the corresponding combustion hole 11, specifically, each ionization position point on each ionization part 21 has a corresponding combustion position point in the corresponding combustion hole 11, and potential difference is formed between the corresponding combustion position point and the ionization position point. In this way, in each combustion hole 11, the gas may be ionized at any position, so that the gas has better ionization reliability, and further, the burner 100 has higher thermal efficiency and better environmental protection performance.

Referring to fig. 2 and 4 again, further, each ionization portion 21 includes an ionization main body portion 212 and a plurality of ionization branch portions 214, the ionization main body is disposed in the corresponding combustion hole 11, all the ionization branch portions 214 are disposed on the ionization main body portion 212 at intervals, and potential differences exist between the ionization main body portion 212, each ionization branch portion 214 and the wall of the corresponding combustion hole 11. Specifically, the ionization main body 212 and each ionization branch 214 have a plurality of combustion points thereon, and the ionization main body 212 and the combustion points on all ionization branches 214 combine to form the outer surface of the ionization section 21. Each ionization position point on the ionization main body portion 212 and each ionization position point on each ionization branch portion 214 have corresponding combustion position points on the wall of the combustion hole 11 corresponding thereto, respectively, and a potential difference is formed between the combustion position points and the ionization position points in one-to-one correspondence. By arranging the ionization main body portion 212 and the plurality of ionization branch portions 214, the surface area of each ionization portion 21 can be effectively increased, so that each ionization portion 21 has more ionization position points, and correspondingly, combustion position points corresponding to the ionization position points respectively exist on the wall of each combustion hole 11. In this manner, the burner 100 has more corresponding ionization sites and potential differences between the combustion sites, thereby enabling the combustion gases to be ionized better.

Alternatively, in each ionization section 21, the ionization main body portion 212 extends in the axial direction of the combustion hole 11 corresponding thereto, and the plurality of ionization branch portions 214 may be arranged at intervals in the extending direction of the ionization main body portion 212, or may also be arranged around the circumferential direction of the ionization main body portion 212, or the like.

Of course, in other embodiments, the shape of the ionization portion 21 is not limited to one of the above, and in another embodiment, each ionization portion 21 may include only the ionization main body portion 212. In other embodiments, there may be a portion of the ionization section 21 including the ionization body portion 212 and a number of ionization branches 214, with the remaining portion of the ionization section 21 including only the ionization body portion 212.

Further, the plurality of combustion holes 11 are arranged in groups to form a plurality of groups of combustion holes, the groups of combustion holes are arranged at intervals along the radial direction of the combustion body 10, and all the combustion holes 11 in each group of combustion holes are arranged at intervals along the circumferential direction of the combustion body 10. Correspondingly, the plurality of ionization parts 21 are arranged in groups to form a plurality of ionization part groups, the plurality of ionization part groups are arranged at intervals along the radial direction of the combustion main body 10, and all ionization parts 21 in each ionization part group are arranged at intervals along the circumferential direction of the combustion main body 10. Therefore, when all the gas in the combustion holes 11 is burned, heat generated by the combustion of the gas can be uniformly diffused to the outside and uniformly heat the cooking appliance.

Further, the ionization member 20 further includes a connection portion 22, and any two ionization portions 21 are connected by the connection portion 22. Thus, the ionization member 20 has better integrity, so as to facilitate the assembly of the ionization member 20. Specifically, the connection portion 22 is also made of a metal material, and the connection portion 22 and the plurality of ionization portions 21 may be integrally formed.

Referring to fig. 3 again, specifically, the combustion main body 10 includes a main housing 12 and a combustion body 14, the main housing 12 has a housing cavity 121, an air inlet 123 and an air outlet 125 are provided on the main housing 12, a plurality of combustion holes 11 are provided on the combustion body 14, and the air inlet 123, the housing cavity 121, each combustion hole 11 and the air outlet 125 are sequentially communicated. Specifically, the main casing 12 and the combustion body 14 are both conductive members, and the main casing 12 has a supporting and protecting function for the combustion body 14, and by providing the main casing 12, the service life of the combustion body 14 can be prolonged, so that the service life of the burner 100 can be further prolonged. Specifically, during the operation of the burner 100, the fuel gas flows in through the air inlet 123 and flows into each combustion hole 11 for combustion after passing through the accommodating cavity 121, and harmless gas generated by the combustion is discharged to the outside from the air outlet 125, while part of heat generated by the combustion is transferred to the cooking appliance through the combustion body 14 and the main housing 12 in sequence, and the rest of heat can be transferred to the cooking appliance through the air pair flowing through the air outlet 125.

Specifically, each combustion hole 11 may penetrate the combustion body 10 in the axial direction of the combustion body 10 and directly communicate with the air outlet 125; alternatively, the combustion body 14 may be a loose porous member, and the combustion body 14 is provided with a plurality of communication holes (not shown), each combustion hole 11 is at least communicated with the air outlet 125 through one communication hole, and different combustion holes 11 are at least communicated with the air outlet 125 through one different communication hole. In addition, the shape of the combustion hole 11 and the shape of the corresponding ionization part 21 are approximately matched, so that the distance between the hole wall of the combustion hole 11 and the corresponding ionization part 21 can be smaller, and the distance between the hole wall of the combustion hole 11 and the corresponding ionization part 21 can meet ionization requirements.

Further, the burner 100 further includes a tempering preventing member 30, where the tempering preventing member 30 is coupled to the accommodating cavity 121 and located at a side of the combustion body 14 facing the air inlet 123, and a plurality of tempering preventing holes are formed in the tempering preventing member 30, and each tempering preventing hole is configured to allow the gas to pass through. Specifically, each tempering preventing hole penetrates the tempering preventing member 30 in the axial direction of the combustion body 10. When the burner 100 is in operation, fuel gas flows into the accommodating chamber 121 from the air inlet 123 and flows into the combustion hole 11 through the backfire preventing hole. During the combustion of the gas in each combustion hole 11, flame generated by the combustion of the gas may overflow in a direction toward the gas inlet 123 to form flashback, and the concentration of the gas at the inlet and outlet is generally greater than that in each combustion hole 11, so that the gas is easily detonated due to the flashback, resulting in serious safety accidents. By arranging the tempering preventing member 30, a plurality of densely arranged tempering preventing holes are arranged on the tempering preventing member 30, and when tempering enters at least part of the tempering preventing holes, the tempering preventing holes are easy to be extinguished due to oxygen deficiency, so that the burner 100 has higher safety.

Alternatively, the flashback arrestor 30 may be spaced from the combustion body 14 or may be disposed in close proximity to the combustion body 14. Preferably, the side of the backfire preventing member 30 facing the combustion body 14 is attached to the combustion body 14. Therefore, the heat generated by the combustion of the fuel gas in each combustion hole 11 can be transferred to the anti-backfire member 30 through the combustion body 14, and the fuel gas can be preheated by the anti-backfire member 30 in the process that the fuel gas passes through the air inlet 123 and the receiving cavity 121 and flows through each anti-backfire hole, thereby enabling the burner 100 to have higher thermal efficiency.

Referring to fig. 2 again, further, the anti-backfire member 30 is recessed toward the surface of the combustion body 14 to form a clearance groove 32, and when the combustion body 14 is attached to the anti-backfire member 30, the connecting portion 22 is accommodated in the clearance groove 32 for clearance. In this way, the tightness of the installation of the combustion body 14 with the anti-backfire 30 can be further improved. It should be noted that, in order to prevent the connection portion 22 from being shorted by contacting the main housing 12 with the tempering member, the connection portion 22 should be spaced from the wall of the clearance groove 32 when the connection portion 22 is received in the clearance groove 32.

The burner 100 further comprises an injection pipe 40 and a nozzle 50, wherein the injection pipe 40 is connected to the air inlet 123 in a matching way and is communicated with the air inlet 123, the nozzle 50 and one end, far away from the air inlet 123, of the injection pipe 40 are arranged at intervals, and the nozzle 50 is used for injecting fuel gas into the injection pipe 40 so that the fuel gas can enter the accommodating cavity 121 through the injection pipe 40 and the air inlet 123. Because the nozzle 50 and the end of the injection pipe 40 far away from the air inlet 123 are arranged at intervals, in the process of injecting the fuel gas from the nozzle 50 to the injection pipe 40, the fuel gas can drive the air surrounding the end of the injection pipe 40 far away from the air inlet 123 and the air surrounding the nozzle 50 to flow into the injection pipe 40 because the fuel gas has higher speed, so that the air can be fully mixed with the fuel gas in the injection pipe 40, thereby further improving the combustion sufficiency and enabling the combustor 100 to have higher thermal efficiency.

The burner 100 further includes an energy concentrating ring 60, the energy concentrating ring 60 being coupled to the air outlet 125 and in communication with the air outlet 125. When the burner 100 works, the cooking appliance is coupled to one end of the energy collecting ring 60 away from the air outlet 125, and heat generated by the combustion of the gas can be transferred to the cooking appliance from the combustion body 14 through the energy collecting ring 60, can be transferred to the cooking appliance through the combustion body 14 and the main housing 12, and can be transferred to the cooking appliance through air convection. The energy collecting ring 60 has an effect of collecting energy, and by providing the energy collecting ring 60, heat can be prevented from being rapidly diffused to the outside, so that the heat can be intensively acted on the cooking appliance, thereby facilitating further improvement of the heat efficiency of the burner 100.

In the above-mentioned burner 100, since each ionization part 21 is inserted into the corresponding combustion hole 11, and a potential difference exists between each ionization part 21 and the wall of the corresponding combustion hole 11, which can ionize the fuel gas and generate the active group, when the fuel gas flows into each combustion hole 11 and burns in the combustion hole 11, the fuel gas can be ionized and form the active group, and the active group can be mixed with the fuel gas and enable the fuel gas to burn sufficiently, thereby improving the thermal efficiency of the burner 100. In addition, the active groups can react with harmful gases (such as carbon monoxide) generated after combustion of the fuel gas and generate harmless gases (such as carbon dioxide), so that the burner 100 has better environmental protection performance. Moreover, since the combustion and ionization of the fuel gas are both performed in the combustion hole 11, the high temperature generated in the combustion process can also promote ionization and generate active groups with higher concentration, so that the combustion can be further promoted and the emission of harmful gases is less, and the burner 100 has higher thermal efficiency and better environmental protection performance.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
